James profile

James Gethi and one of the crops closest to his heart – maize. He also has a soft spot for hardy crop varieties that survive harsh and unforgiving drylands, such as Machakos, Kenya, where this June 2011 photo of him with drought-tolerant KARI maize was taken.

As we tell our closing stories on our Sunset Blog, in parallel, we’re also catching up on the backlog of stories still in our store from the time GCP was a going concern. Our next stop is Kenya, and the narrative below is from 2012, but don’t go away as it is an evergreen – a tale that can be told at any time, as it remains fresh as ever. At that time, and for the duration of the partnership with GCP, the Food Crops Research Institute of the Kenya Agricultural and Livestock Research Organisation (KALRO) was then known as the Kenya Agricultural Research Institute (KARI), and we shall therefore stay with this previous name in the story. KARI was also the the name of the Kenyan institute at the time when James Gethi (pictured) left for a sabbatical at the International Maize and Wheat Improvement Center (CIMMYT by its Spanish acronym). On to the story then, and please remember we’re travelling back in time to the year 2012. 

“I got into science by chance, for the fun of it,” muses James, maize breeder and former GCP scientist “With agricultural school promising a flight to overfly the country’s agricultural areas– this was an interesting prospect for a village guy. ‘This could be fun’, I thought!”

And it turned out to be a chance well worth taking.  His first step was getting the requisite education. And so he armed himself with a BSc in Agriculture from the University of Nairobi, Kenya, topped with a Master’s and PhD in Plant Breeding from the University of Alberta (Canada) and Cornell University (USA), respectively. Beyond academics, in the course of his crop science career, James has developed 13 crop varieties, that included maize and cassava, published papers in numerous peer-reviewed papers (including the 2003 prize for Best paper in the field of crop science in the prestigious Crop Science journal. And in leadership, James headed the national maize research programme in his native Kenya. These are just a few of the achievements James has garnered in the course of his career, traversing  and transcending not only the geographical frontiers initially in his sights, but also scientific ones, reaching professional heights that perhaps his younger self might never have dreamt possible.

As a Research Officer at KARI, a typical day sees James juggling his time between hands-on research (developing maize varieties resistant to drought, field and storage pests) and project administration, coordinating public–private partnerships and the maize research programme at both institutional and country level. What motivates the man shouldering much of the responsibility for the buoyancy of his nation’s staple crop? James explains, “Making a difference by providing solutions to farmers. That’s my passion and that’s what makes me get up in the morning and go to work. It’s hugely satisfying!”

Without GCP, I would not be where I am today as a scientist… [it] gave me a chance to work with the best of the best worldwide… You develop bonds and understanding that last well beyond the life of the projects.”

Rapid transitions: trainee to trainer to leader
It was this passion and unequivocal dedication to his vocation – not to mention a healthy dollop of talent – that GCP was quick to recognise back in 2004, when James first climbed aboard the GCP ship. Like a duck to water, he proceeded to engage in all manner of GCP projects and related activities, steadily climbing the ranks from project collaborator to co-Principal Investigator and, finally, Principal Investigator in his own right, leading a maize drought phenotyping project. Along the way, he also secured GCP Capacity building à la carte and Genotyping Support Service grants to further the maize research he and his team were conducting.

From trainee to trainer and knowledge-sharer: James (behind the camera) training KARI staff on drought phenotyping in June 2009 at Machakos, in Kenya’s drylands.

The GCP experience, James reveals, has been immensely rewarding: “Without GCP, I would not be where I am today as a scientist,” he asserts. And on the opportunity to work with a capable crew beyond national borders, as opposed to operating as a solo traveller, he says: “GCP gave me a chance to work with the best of the best worldwide, and has opened up new opportunities and avenues for collaboration between developing-country researchers and advanced research institutes, creating and cementing links that were not so concrete before. This has shown that we don’t have to compete with one another; we can work together as partners to derive mutual benefits, finding solutions to problems much faster than we would have done working alone and apart from each other.”

The links James has in mind are not only tangible but also sustainable: “You develop bonds and understanding that last well beyond the life of the projects,” James enthuses, citing additional professional engagements (the African Centre for Crop Improvement in KwaZulu-Natal, South Africa, and the West Africa Centre for Crop Improvement, have both welcomed James and his team into their fold), as well as firm friendships with former GCP project colleagues as two key take-home benefits of his interaction with the Programme. These new personal and professional circles have fostered a happy home for dynamic debates on the latest news and views from the crop-science world, and the resultant healthy cross-fertilisation of ideas, James affirms.

Reflecting on what he describes as a ‘mentor’ role of GCP, and on the vital importance of capacity building in general, he continues: “By enhancing the ability of a scientist to collect germplasm, or to analyse that germplasm, or by providing training and tips on how to write a winning project proposal to get that far in the first place, you’re empowering scientists to make decisions on their own – decisions which make a difference in the lives of farmers. This is tremendous empowerment.”

Another potent tool, says James, is the software made available to him through GCP’s Integrated Breeding Platform (IBP), which is a handy resource package to dip into for – among other things – analysing data and selecting the right varieties at the right time. The next step for IBP, he feels, should be scaling up and aiming for outreach to the wider scientific community, forecasting that such a step could bring nothing but success: “The impacts could be enormous!” he projects, with a palpable and infectious enthusiasm.

People… don’t eat publications, they eat food… I’m not belittling knowledge, but we can do both”

Fast but not loose on the R&D continuum: double agent about?
For James, outreach and impacts are not limited to science alone. In parallel with his activities in upstream genetic science, James’ efforts are equally devoted to the needs of his other client base-–the development community and farmers. For this group, James’ focus is on putting tangible products on the table that will translate into higher crop yields and incomes for farmers. Yet whilst products from any highly complex scientific research project worth its salt are typically late bloomers, often years in the making on a slow burner as demanded by the classic linear R&D view that research must always precede development, adaptation and final adoption, James has been quick to recognise that actors in the world of development and the vulnerable communities they serve do not necessarily have this luxury of time.

August 2008: a huge handful, and more where that came from in Kwale, Kenya. This farmer's healthy harvest came from KARI hybrids.

August 2008: a huge handful, and more where that came from in Kwale, Kenya. This farmer’s healthy harvest came from KARI hybrids.

His solution for this challenge? “Sitting where I sit, I realised from very early on that if I followed the traditional linear scientific approach, my development clients would not take it kindly if I still had no products for them within the three-year lifespan of the project. The challenge then was to deliver results for farmers without compromising or jeopardising their integrity or the science behind the product,” he recalls. In the project he refers to – a GCP-funded project to combat drought and disease in maize and rice – James applied a novel double-pronged approach to get around this seeming conundrum of the need for sound science on the one hand, and the need for rapid results for development on the other hand. Essentially, he simultaneously walked on both tracks of the research–development continuum.

The project – led by Rebecca Nelson of Cornell University and with collaborators including James’ team at KARI (leading the maize component), the International Rice Research Institute (IRRI), researchers in Asia, as well as other universities in USA – initially set out with the long-term goal of dissecting quantitative trait loci (QTLs) for rice and maize with a view to combating drought and disease in these crops. Once QTLs were dissected and gene crosses done, James and his team went about backcrossing these new lines to local parental lines, generating useful products in the short term. The results, particularly given the limited resources and time invested, have been impressive, with seven hybrid varieties developed for drylands and coastal regions having been released in Kenya by 2009, and commercialised from 2010.

James and his colleagues have applied the same innovative approach to other GCP projects, grappling to get a good grasp of the genetic basis of drought tolerance, whilst also generating intermediate products for practical use by farmers along the way. James believes this dual approach paves the way for a win-win situation: “People on the ground don’t eat publications, they eat food,” he says. “As we speak now, there are people out there who don’t know where their next meal will come from. I’m not belittling knowledge, but we can do both – boiled maize on the cob and publications on the boil. But let’s not stop at crop science  and knowledge dissemination – let’s move it to the next level, which means products,” he challenges, adding: “With GCP support, we were able do this, and reach our intended beneficiaries.”

It is perhaps this kind of vision and inherent instinct to play the long game that has taken James this far professionally, and that will no doubt also serve him well in the future.

As our conversation comes to a close, we ask James for a few pearls of wisdom for other young budding crop researchers eager to carve out an equally successful career path for themselves, James offers “Form positive links and collaborations with colleagues and peers. Never give up; never let challenges discourage you. Look for organisations where you can explore the limits of your imagination. Stay focused and aim high, and you’ll reach your goal.”

Upon completion of his ongoing sabbatical at CIMMYT in Zimbabwe, where he is currently working on seed systems, James plans to return to KARI, armed with fresh knowledge and ready to seize – with both hands – any promising collaborative opportunities that may come his way .

Certainly, prospects look plentiful for this ‘village lad’ in full flight, and who doesn’t look set to land any time soon!

In full flight – Montpellier, Brazil, Benoni, Bangkok, Bamako, Hyderabad… our boy voyaged from the village to Brazil and back, and far beyond that. Sporting the t-shirt from GCP’s Annual Research Meeting in Brazil in 2006, which James attended, he also attended the same meeting the following year, in Benoni, South Africa, in 2007, when this photo was taken. James is a regular at these meetings which are the pinnacle on  GCP’s calendar (http://bit.ly/I9VfP4). But he always sings for his supper and is practically part of the ‘kitchen crew’, but just as comfortable in high company. For example, he was one of the keynote speakers at the 2011 General Research Meeting (see below).

Peasant lad to leading professor: Paul and his passion for pods

Beyond chickpeas to embrace beans, chickpeas, groundnuts and pigeonpeas

Paul_w2As a scientist who comes from the dessicated drylands of the unforgiving Kerio Valley, where severe drought can mean loss of life through loss of food and animals, what comes first is food security… I could start to give something back to the community… It’s been a dream finally coming true.” – Paul Kimurto, Senior Lecturer and Professor in Crop Physiology and Breeding, Egerton University, Kenya

As a son of peasant farmers growing up in a humble home in the Rift Valley of Kenya, agriculture was, for Paul Kimurto (pictured above), not merely a vocation but a way of life: “Coming from a pastoral community, I used to take care of the cattle and other animals for my father. In my community livestock is key, as is farming of food crops such as maize, beans and finger millet.”

Covering some six kilometres each day by foot to bolster this invaluable home education with rural school, an affiliation and ever-blossoming passion for agriculture soon led him to Kenya’s Egerton University.

There, Paul excelled throughout his undergraduate course in Agricultural Sciences, and was thus hand-picked by his professors to proceed to a Master’s degree in Crop Sciences at the self-same university, before going on to obtain a German Academic Exchange Service (DAAD) scholarship to undertake a ‘sandwich’ PhD in Plant Physiology and Crop Breeding at Egerton University and the Leibniz Institute for AgriculturalEngineering (ATB) in Berlin, Germany.

… what comes first is food security… offering alternative drought-tolerant crops… is a dream finally coming true!…  GCP turned out to be one of the best and biggest relationships and collaborations we’ve had.”

Local action, global interaction
With his freshly minted PhD, Paul returned to Egerton’s faculty staff and steadily climbed the ranks to his current position as Professor and Senior Lecturer in Crop Physiology and Breeding at Egerton’s Crop Sciences Department. Yet for Paul, motivating this professional ascent throughout has been one fundamental factor:  “As a scientist who comes from a dryland area of Kerio valley, where severe drought can mean loss of food and animals, what comes first is food security,” Paul explains. “Throughout the course of my time at Egerton, as I began to understand how to develop and evaluate core crop varieties, I could start to give something back to the community, by offering alternative drought-tolerant crops like chickpeas, pigeonpeas, groundnuts and finger millet that provide farmers and their families with food security. It’s been a dream finally coming true.”

And thus one of academia’s true young-guns was forged: with an insatiable thirst for moving his discipline forward by seeking out innovative solutions to real problems on the ground, Paul focused on casting his net wide and enhancing manpower through effective collaborations, having already established fruitful working relationships with the International Maize and Wheat Improvement Center (CIMMYT), the (then) Kenya Agricultural Research Institute (KARI) and the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) in earlier collaborative projects on dryland crops in Kenya. It was this strategy that paved the way towards teaming up with GCP, when, in 2008, Paul and his team were commissioned to lead the chickpea work in Kenya for the GCP Tropical Legumes I project (TLI), with local efforts being supported by colleagues at ICRISAT, and friends down the road at KARI undertaking the bean work of the project. Climbing aboard the GCP ship, Paul reveals, was a move worth making: “Our initial engagement with GCP started out as a small idea, but in fact, GCP turned out to be one of the best and biggest relationships and collaborations we’ve had.”

…GCP is people-oriented, and people-driven” 

Power to the people!
The success behind this happy marriage, Paul believes, is really quite simple: “The big difference with GCP is that it is people-oriented, and people-driven,” Paul observes, continuing: “GCP is building individuals: people with ideas become equipped to develop professionally.” Paul elaborates further: “I wasn’t very good at molecular breeding before, but now, my colleagues and I have been trained in molecular tools, genotyping, data management, and in the application of molecular tools in the improvement of chickpeas through GCP’s Integrated Breeding Multiyear Course. This has opened up opportunities for our local chickpea research community and beyond, which, without GCP’s support, would not have been possible for us as a developing-country institution.”

Passionate about his teaching and research work, it’s a journey of discovery Paul is excited to have shares with others: “My co-workers and PhD students have all benefitted. Technicians have been trained abroad. All my colleagues have a story to tell,” he says. And whilst these stories may range from examples of access to training, infrastructure or genomic resources, the common thread throughout is one of self-empowerment and the new-found ability to move forward as a team: “Thanks to our involvement with the GCP’s Genotyping Support Service, we now know how to send plant DNA to the some of the world’s best labs and to analyse the results, as well as to plan for the costs. With training in how to prepare the fields, and infrastructure such as irrigation systems and resources such as tablets, which help us to take data in the field more precisely, we are now generating accurate research results leading to high-quality data.”

The links we’ve established have been tremendous, and we think many of them should be long-lasting too: even without GCP“

Teamwork, international connections and science with a strong sense of mission
Teaming up with other like-minded colleagues from crème de la crème institutions worldwide has also been vital, he explains: “The links we’ve established have been tremendous, and we think many of them should be long-lasting too: even without GCP, we should be able to sustain collaboration with KBioscience [now LGC Genomics] or ICRISAT for example, for genotyping or analysing our data.” He holds similar views towards GCP’s Integrated Breeding Platform (IBP): “IBP is one of the ideas which we think, even after GCP’s exit in December 2014, will continue to support our breeding programmes. My colleagues and I consult IBP regularly for a range of aspects, from markers to protocols to germplasm and the helpdesk, as well as for contacts and content available via the IBP Communities of Practice.” Paul’s colleagues are Richard Mulwa, Alice Kosgei, Serah Songok, Moses Oyier, Paul Korir, Bernard Towett, Nancy Njogu and Lilian Samoei. Paul continues: “We’ve also been encouraging our regional partners to register on IBP – I believe colleagues across Eastern and Central Africa could benefit from this one-stop shop.”

Yet whilst talking animatedly about the greater sophistication and accuracy in his work granted as a result of new infrastructure and the wealth of molecular tools and techniques now available to him and his team, at no point do Paul’s attentions stray from the all-important bigger picture of food security and sustainable livelihoods for his local community: “When we started in 2008, chickpeas were known as a minor crop, with little economic value, and in the unfavoured cluster termed ‘orphan crops’ in research. Since intensifying our work on the crop through TLI, we have gradually seen chickpeas become, thanks to their relative resilience against drought, an important rotational crop after maize and wheat during the short rains in dry highlands of Rift valley and also in the harsh environments of the Kerio Valley and swathes of Eastern Kenya.”

This GCP-funded weather station is at Koibatek Farmers Training Centre, Longisa Division, Bomet County.

Having such a back-up in place can prove a vital lifeline to farmers, Paul explains, particularly during moments of crisis, citing the 2011–2012 outbreak of the maize lethal necrosis (MLN) disease which wiped out all the maize throughout Kenya’s  Bomet County, where Paul, Richard, Bernard and their team had been working on the chickpea reference set. Those farmers who had planted chickpeas – Paul recalls Toroto and Absalom as two such fortunate souls – were food-secure. Moreover, GCP support for infrastructure such as a weather station have helped farmers in Koibatek County to predict weather patterns and anticipate rainfall, whilst an irrigation system in the area is being used by the Kenyan Ministry of Agriculture to develop improved seed varieties and pasture for farmers.

The science behind the scenes and the resultant products are of course not to be underestimated: in collaboration with ICRISAT, Paul and his team released four drought-resistant chickpea varieties in Kenya in 2012, with the self-same collaboration leading to the integration of at least four varieties of the crop using marker-assisted backcrossing, one of which is in the final stages and soon to be released for field testing. With GCP having contributed to the recent sequencing of the chickpea genome, Paul and his colleagues are now looking to up their game by possibly moving into work on biotic stresses in the crop such as diseases, an ambitious step which Paul feels confident can be realised through effective collaboration, with potential contenders for the mission including ICRISAT (for molecular markers), Ethiopia and Spain (for germplasm) and researchers at the International Center for Agricultural Research in the Dry Areas (ICARDA) for germplasm. Paul first established contact with all of these partners during GCP meetings.

By coming together, pooling skills from biotechnology, agronomy, breeding, statistics and other disciplines, we are stronger as a unit and better equipped to offer solutions to African agriculture and to the current challenges we face.”

Links that flower, a roving eye, and the heat is on!
In the meantime, the fruits of other links established since joining the GCP family are already starting to blossom. For example, TLI products such as certified seeds of chickpea varieties being released in Kenya – and in particular the yet-to-be-released marker-assisted breeding chickpea lines which are currently under evaluation – caught the eye of George Birigwa, Senior Programme Officer at the Program for Africa’s Seed Systems (PASS) initiative of the Alliance for a Green Revolution in Africa (AGRA), which is now supporting the work being undertaken by Paul and his team through the Egerton Seed Unit and Variety Development Centre (of which Paul is currently Director) at the Agro-Based Science Park.

Yet whilst Paul’s love affair with chickpeas has evidently been going from strength to strength, he has also enjoyed a healthy courtship with research in other legumes: by engaging in a Pan-African Bean Research Alliance (PABRA) bean project coordinated by the International Center for Tropical Agriculture (CIAT), Paul and his team were able to release and commercialise three bean varieties which are currently in farmers’ fields in Kenya.

With so many pots on the boil, the heat is certainly on in Paul’s research kitchen, yet he continues to navigate such daily challenges with characteristic aplomb. As a proven leader of change in his community and a ‘ can-do, make-it-happen’ kind of guy, he is driving research forward to ensure that both his school and discipline remain fresh and relevant – and he’s taking his colleagues, students and local community along with him every step of  the way.

Indeed, rallying the troops for the greater good is an achievement he values dearly: “By coming together, pooling skills from biotechnology, agronomy, breeding, statistics and other disciplines, we are stronger as a unit and better equipped to offer solutions to African agriculture and to the current challenges we face,” he affirms. This is a crusade he has no plans to abandon any time soon, as revealed when quizzed on his future aspirations and career plans: “My aim is to continue nurturing my current achievements, and to work harder to improve my abilities and provide opportunities for my institution, colleagues, students, friends and people within the region.”

With the chickpea research community thriving, resulting in concrete food-security alternatives, we raise a toast to Paul Kimurto and his chickpea champions!

2 – 1 = 3: Seeking sorghum solutions, breeding for more yield with less water

 Africa, Crop breeding, Genetics, Genomics, Sorghum  No Responses »
Aug 292014
 
One of the greatest challenges of our time is growing more crops to feed more people, but using less water

Sorghum is one of the most ‘efficient’ crops in terms of needing less water and nutrients to grow. And although it is naturally well-adapted to sun-scorched drylands, there is still a need to improve its yield and broad adaptability in these harsh environments. In West Africa, for example, while sorghum production has doubled in the last 20 years, its yield has remained stagnant – and low.

The GCP Sorghum Research Initiative comprises several projects, which are exploring ways to use molecular-breeding techniques to improve sorghum yields, particularly in drylands. All projects are interdisciplinary international collaborations with an original focus on Mali, where sorghum-growing areas are large and rainfall is getting more erratic and variable. Through the stay-green project, the research has since broadened to also cover Burkina Faso, Ethiopia, Kenya, Niger and Sudan.

Using molecular markers is new and exciting for us as it will speed up the breeding process. With molecular markers, you can easily see if the plant you’ve bred has the desired characteristics without having to grow the plant and or risk missing the trait through visual inspection.”

What’s MARS got to do with it?

Niaba Témé is a local plant breeder and researcher at Mali’s L’Institut d’économie rurale (IER). He grew up in a farming community on the southern edge of the Sahara Desert, where crops would constantly fail during drier-than-normal seasons.

Niaba says these crop failures were in part his inspiration for a career where he could help farmers like his parents and siblings protect themselves from the risks of drought and extreme temperatures.

For the past four years, Niaba and his team at IER have been collaborating with Jean-François Rami and his team at France’s Centre de coopération internationale en recherche agronomique pour le développement (CIRAD), to improve sorghum grain yield and quality for West African farmers. The work is funded by the Syngenta Foundation for Sustainable Agriculture.

“With the help of CIRAD and Syngenta, we have been learning how to use molecular markers to improve breeding efficiency of sorghum varieties more adapted to the variable environment of Mali and surrounding areas which receive less than 600 millimetres of rainfall per year,” he says.

“Using molecular markers is new and exciting for us as it will speed up the breeding process. With molecular markers, you can easily see if the plant you’ve bred has the desired characteristics without having to grow the plant and or risk missing the trait through visual inspection.”

Jean-François Rami, who is the project’s Principal Investigator, has been impressed by the progress made so far. Jean-François is also GCP’s Product Delivery Coordinator for sorghum.

“Since its inception, the project has progressed very well,” says Jean-François. “With the help of the IER team, we’ve been able to develop two bi-parental populations from elite local varieties, targeting two different environments of sorghum cropping areas in Mali. We’ve then been able to use molecular markers through a process called marker-assisted recurrent selection [MARS] to identify and monitor key regions of the genome in consecutive breeding generations.”

The collaboration with Syngenta came from a common perspective and understanding of what approach could be effectively deployed to rapidly deliver varieties with the desired characteristics.

“Syngenta came with their long experience in implementing MARS in maize. They advised on how to execute the programme and avoid critical pitfalls. They offered to us the software they have developed for the analysis of data which allowed the project team to start the programme immediately,” says Jean-François.

Like all GCP projects, capacity building is a large part of the MARS project. Jean-François says GCP has invested a lot to strengthen IER’s infrastructure and train field technicians, researchers and young scientists. But GCP is not the only player in this: “CIRAD has had a long collaboration in sorghum research in Mali and training young scientists has always been part of our mission. We’ve hosted several IER students here in France and we are interacting with our colleagues in Mali either over the phone or travelling to Mali to give technical workshops in molecular breeding. The Integrated Breeding Platform [IBP] has also been a breakthrough for the project, providing to the project team breeding services, data management tools, and a training programme – the Integrated Breeding Multiyear Course [IB–MYC].”

We don’t have these types of molecular-breeding resources available in Mali, so it’s really exciting to be a part of this project… the approach has the potential to halve the time it takes to develop local sorghum varieties with improved yield and adaptability to drought… one of the great successes of the project has been to bring together sorghum research groups in Mali in a common effort to develop new genetic resources for sorghum breeding.”

Back-to-back: more for Mali’s national breeding programme

On the back of the MARS project, Niaba successfully obtained GCP funding in 2010 to carry out similar research with CIRAD and collaborators in Africa at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT).

“In this project, we are trying to enhance sorghum grain yield and quality for the Sudano-Sahelian zone of West Africa using the backcross nested association mapping (BCNAM) approach,” explains Niaba, who is the Principal Investigator of the BCNAM project. “This involves using an elite recurrent parent that is already adapted to local drought conditions. The benefit of this approach is that it can lead to detecting elite varieties much faster.”

Eva Weltzien has been the Principal Scientist for ICRISAT’s sorghum breeding programme in Mali since 1998. She says the project aligned with much of the work her team had been doing, so it made sense to collaborate considering the new range of sorghum genetic diversity that this approach aims to use.

“We’ve been working with Niaba’s team to develop 100 lines for 50 populations from backcrosses carried out with 30 recurrent parents,” explains Eva. “These lines are being genotyped by CIRAD. We will then be able to use molecular markers to determine if any of these lines have the traits we want. We don’t have these types of molecular-breeding resources available in Mali, so it’s really exciting to be a part of this project.”

Eva says that the approach has the potential to halve the time it takes to develop local sorghum varieties with improved yield and adaptability to drought.

For Jean-François, one of the great successes of the project has been to bring together sorghum research groups in Mali in a common effort to develop new genetic resources for sorghum breeding.

“This project has strengthened the IER and ICRISAT partnerships around a common resource. The large multiparent population that has been developed is analysed collectively to decipher the genetic control of important traits for sorghum breeding in Mali,” says Jean-François.

 Plants with this ‘stay-green’ trait keep their leaves and stems green during the grain-filling period. Typically, these plants have stronger stems, higher grain yield and larger grain.”

Sorghum staying green and strong, with less water

In February 2012, Niaba and his colleague, Sidi B Coulibaly, were invited to Australia as part of another Sorghum Research Initiative project they had been collaborating on with CIRAD, Australia’s University of Queensland and the Queensland Department of Agriculture, Fisheries and Forestry (QDAFF).

“We were invited to Australia for training by Andrew Borrell and David Jordan, who are co-Principal Investigators of the GCP stay-green sorghum project,” says Niaba.

“We learnt about association mapping, population genetics and diversity, molecular breeding, crop modelling using climate forecasts, and sorghum physiology, plus a lot more. It was intense but rewarding – more so the fact that we understood the mechanics of these new stay-green crops we were evaluating back in Mali.”

It wasn't all work and there was clearly also time to play, as we can see her., Sidi Coulibaly and Niaba Teme visiting with the Borrell family in Queensland, Australia.

Stay-green is a post-flowering drought adaptation trait that has contributed significantly to sorghum yield stability in northeastern Australia and southern USA over the last two decades.

Andrew has been researching how the drought-resistant trait functions for almost 20 years, including gene discovery. In 2010, he and his colleague, David Jordan, successfully obtained funding from GCP to collaborate with IER and CIRAD to develop and evaluate drought-adapted stay-green sorghum germplasm for Africa and Australia.

“Stay-green sorghum grows a canopy that is about 10 per cent smaller than other lines. So it uses less water before flowering,” explains Andrew. “More water is then available during the grain-filling period. Plants with this ‘stay-green’ trait keep their leaves and stems green during the grain-filling period. Typically, these plants have stronger stems, higher grain yield and larger grain.”

Andrew says the project is not about introducing stay-green into African germplasm, but rather, enriching the pre-breeding material in Mali for this drought-adaptive trait.

The project has three objectives:

  1. To evaluate the stay-green drought-resistance mechanism in plant architecture and genetic backgrounds appropriate to Mali.
  2. To develop sorghum germplasm populations enriched for stay-green genes that also carry genes for adaptation to cropping environments in Mali.
  3. To improve the capacity of Malian researchers by carrying out training activities for African sorghum researchers in drought physiology and selection for drought adaptation in sorghum.

…we have found that the stay-green trait can improve yields by up to 30 percent in drought conditions with very little downside during a good year, so we are hoping that these new lines will display similar characteristics”

Expansion and extension:  beyond Mali to the world

Andrew explains that there are two phases to the stay-green project. The project team first focused on Mali. During this phase, the Australian team enriched Malian germplasm with stay-green, developing introgression lines, recombinant inbred lines and hybrids. Some of this material was field-tested by Sidi and his team in Mali.

“In the past, we have found that the stay-green trait can improve yields by up to 30 percent in drought conditions with very little downside during a good year, so we are hoping that these new lines will display similar characteristics,” says Andrew. “During the second phase we are also collaborating with ICRISAT in India and now expanding to five other African countries – Niger and Burkina Faso in West Africa; and Kenya, Sudan and Ethiopia in East Africa. During 2013, we grew our stay-green enriched germplasm at two sites in all these countries. We also hosted scientists from Burkina Faso, Sudan and Kenya to undertake training in Queensland in February 2014.”

Andrew says that the collaboration with international researchers has given them a better understanding of how stay-green works in different genetic backgrounds and in different environments, and the applicability is broad. Using these trial data will help provide farmers with better information on growing sorghum, not just in Africa and Australia, but also all over the world.

“Both David and I consider it a privilege to work in this area with these international institutes. We love our science and we are really passionate to make a difference in the world with the science we are doing. GCP gives us the opportunity to expand on what we do in Australia and to have much more of a global impact.”

We’ll likely be hearing more from Andrew on the future of this work at GCP’s General Research Meeting (GRM) in October this year, so watch this space!

The curious case of cassava’s quirks, narrated in Nigeria

 Africa, Cassava  4 Responses »
Jun 242014
 

Triumphs and tragedies, pitfalls and potential of the ‘camel crop’Cassava leaf. Photo: N Palmer/CIAT

We travel through space and time, with a pair of researchers who have a pronounced passion for a plant brought to Africa by seafaring Portuguese traders in the 16th century. Fastforwarding to today, half a millennium later, the plant is widespread and deep inland, and is the staple food for Africa’s most populous nation – Nigeria.

Meet cassava, the survivor. After rice and maize, cassava is the third-largest source of carbohydrate in the tropics. Surviving, nay thriving, in poor soils and shaking off the vagaries of weather – including an exceptionally high threshold for drought – little wonder that cassava, the ‘camel’ of crops is naturally the main staple in Nigeria. And with that, it has propelled Nigeria to the very top of the cassava totem pole as the world’s leading cassava producer, and consumer: most Nigerians eat cassava in one form or another practically every day.

Great, huh? But there’s also a darker side to cassava, as we will soon find out from our two cassava experts. For starters, the undisputed global cassava giant, Nigeria, produces just enough to feed herself. Even if there were a surplus for the external demand, farming families, which make up 70 percent of the Nigerian population, have limited access to these lucrative external markets. Secondly, cassava mosaic disease (CMD) and cassava brown streak disease (CBSD) are deadly in Africa. Plus, cassava is a late bloomer (up to two years growth cycle, typically one year), so breeding and testing improved varieties takes time. Finally, cassava is most definitely not à la mode at all in modern crop breeding: the crop is an unfashionably late entrant into the world of molecular breeding, owing to its complex genetics which denied cassava the molecular tools that open the door to this glamour world of ‘crop supermodels’.

But all is not doom and gloom, which inexorably dissolve in the face of dogged determination. All the above notwithstanding, cassava’s green revolution seems to be decidedly on the way in Nigeria, ably led by born-and-bred sons of the soil: Chiedozie Egesi and Emmanuel Okogbenin (pictured right) are plant breeders and geneticists at the National Root Crops Research Institute (NRCRI). With 36 years’ collective cassava research experience between them, the two men are passionate about getting the best out of Nigeria’s main staple crop, and getting their hands into the sod while about it: “I’m a plant breeder,” says Chiedozie, with pride. “I don’t just work in a laboratory. I am also in the field to experience the realities.”

Hitting two birds with one stone…two stones are even better!
As Principal Investigators (PIs) leading three different projects in the GCP-funded Cassava Research Initiative, Chiedozie and Emmanuel, together with other colleagues from across Africa, form a formidable team. They also share a vision to enable farmers increase cassava production for cash, beyond subsistence. This means ensuring farmers have new varieties of cassava that guarantee high starch-rich yields in the face of evolving diseases and capricious weather.

Chiedozie is one of cassava’s biggest fans. His affection for, and connection to, cassava is almost personal and definitely paternal. He is determined to deploy the best plant-breeding techniques to not only enhance cassava’s commercial value, but to also protect the crop against future disease outbreaks, including ‘defensive‘ breading. But more on that later…

Emmanuel is equally committed to the cassava cause. As part of his brief, Emmanuel liaises with the Nigerian government, to develop for – and promote to – farmers high-starch cassava varieties. This ensures a carefully crafted multi-pronged strategy to revolutionise cassava: NRCRI develops and releases improved varieties, buttressed by financial incentives and marketing opportunities that encourage farmers to grow and sell more cassava, which spurs production, thereby simultaneously boosting food security while also improving livelihoods.

Standing tall. Disease resistance and high starch and yield aside, farmers also prefer an upright architecture, which not only significantly increases the number of plants per unit, but also favours intercropping, a perennial favourite   for cassava farmers.

Cross-continental crosses and cousins, magic for making time, and clocking a first for cassava

No one has been able to manufacture time yet, so how can breeders get around cassava’s notoriously long breeding cycle? MAS (marker-assisted selection) is crop breeding’s magic key for making time. And just as humans can benefit from healthy donor organ replacement, so too does cassava, with cross-continental cousins donating genes to rescue the cousin in need. Latin American cassava is nutrient-rich, while African cassava is hardier, being more resilient to pests, disease and harsh environments.

Thanks to marker-assisted breeding, CMD resistance from African cassava can now be rapidly ‘injected’ much faster into Latin American cassava for release in Africa. Consequently, in just a three-year span (2010–2012), Chiedozie, Emmanuel, Martin Fregene of the Donald Danforth Plant Science Center (USA) and the NRCRI team, released two new cassava varieties from Latin American genetic backgrounds (CR41-10 and CR36-5). These varieties, developed with GCP funding, are the first molecular-bred cassava ever to be released, meaning they are a momentous milestone in cassava’s belated but steady march towards its own green revolution.

Marker-assisted selection is much cheaper, and more focused.” 

On the cusp of a collaborative cassava revolution: on your marks…
With GCP funding, Chiedozie and Emmanuel have been able to use the latest molecular-breeding techniques to speed up CMD resistance. Using marker-assisted selection (MAS) which is much more efficient, the scientists identified plants combining CMD resistance with desirable genetic traits.

“MAS for CMD resistance from Latin American germplasm is much cheaper, and more focused,” explains Emmanuel. “There is no longer any need to ship in tonnes of plant material to Africa. We can narrow down our search at an early stage by selecting only material that displays markers for the genetic traits we’re looking for.” Using markers, combining traits (known as ‘gene pyramiding’) for CMD resistance is faster and more efficient, as it is difficult to distinguish phenotypes with multiple resistance in the field by just observing with the naked eye. This is what makes marker-assisted breeding so effective and desirable in Africa.

GCP’s mode of doing business coupled with its community spirit has spurred the NRCRI scientists to cast their eyes further out to the wider horizon beyond their own borders.

By collaborating with research centres in other parts of the world, Emmanuel and Chiedozie have made remarkable strides in cassava breeding. According to Emmanuel, “GCP helped us make links with advanced laboratories and service providers like LGC Genomics. The outsourcing of genotyping activities for molecular breeding initiatives is very significant, as it enables us to carry out analyses not otherwise possible.”

We can’t afford to sit idle until it comes – we need to be armed and on the ready.”

‘Defensive’ breeding: partnerships to pre-empt catastrophe and combat disease
Closer home in Africa, as PI of the corollary African breeders community of practice (CoP) project, Emmanuel co-organises regular workshops with plant breeders from a dozen other countries (Côte d’Ivoire, DR Congo, Ethiopia, Ghana, Kenya,  Liberia, Malawi, Mozambique, Sierra Leone, Tanzania, Uganda and South Sudan). These events are an opportunity to share knowledge on molecular breeding and compare notes.

Of the diseases that afflict cassava, CBSD is the most devastating. Mercifully, in Nigeria, the disease is non-existent, but Chiedozie is emphatic that this is by no means cause for complacency. “If CBSD gets to Nigeria, it would be a monumental catastrophe!” he cautions. “We can’t afford to sit idle until it comes – we need to be armed and on the ready.”

Putting words to action, though this work on CBSD resistance is still in its early stages, more than 1,000 cassava genotypes (different genetic combinations) have already have been screened in the course of just one year. Chiedozie hopes that the team will be able to identify key genetic markers, and validate these in field trials in Tanzania, where CBSD is widespread. This East African stopover, Chiedozie emphasises, is a crucial checkpoint in the West African process. So the cassava CoP not only provides moral but also material support.

And Africa is not the limit. GCP-funded work on CMD resistance is more advanced than the CBSD work, though the real breakthrough in CMD only happened recently, on the international arena within which the African breeders now operate. According to Chiedozie, two entire decades of screening cassava genotypes from Latin America yielded no resistance to CMD. The reason for this is that although it is widespread in Africa, CMD is non-existent in Latin America.

Through international collaborative efforts, cassava scientists, led by Martin Fregene (now based in USA), screened plants from Nigeria and discovered markers for the CMD2 gene, indicating resistance to CMD. Once they had found these markers, the scientists were off and away! By taking the best of the Latin American material and crossing it with Nigerian genotypes that have CMD resistance, promising lines were developed from which the Nigerian team produced two new varieties. These varieties, CR41-10 and CR36-5, have already been released to farmers, and that is not all. More varieties bred using these two as parents are in the pipeline.

“GCP funding has given us the opportunity to show that a national organisation can do the job and deliver.” 

 

Delivery attracts
The success of the CGP-funded cassava research in Nigeria lies in its in-country leadership. Chiedozie, Emmanuel and Martin are native Nigerian scientists and as such are – in many ways – best placed to drive a research collaboration to benefit the country’s farmers and boost food security. “GCP funding has given us the opportunity to show that a national organisation can do the job and deliver,” says Chiedozie.

This proven expertise has helped NRCRI forge other partnerships and attract more financial support, for example from the Bill & Melinda Gates Foundation for a project on genomic selection. GCP support has also bolstered communications with the Nigerian government, which has launched financial instruments, such as a wheat tariff,* to boost cassava production and use.

[Editors note: * wheat tariff: The Nigerian government is trying to reduce wheat import bills and also boost cassava commercialisation by promoting 20 percent wheat substitution in bread-making. Tariffs are being imposed on wheat to dissuade heavy imports and encourage utilisation of high-quality cassava flour for bread.]

“The government feels that to quickly change the fortunes of farmers, cassava is the way to go,” explains Emmanuel. He clarifies, “The tariff from wheat is expected to be ploughed back to support agricultural development – especially the cassava sector – as the government seeks to increase cassava production to support flour mills. Cassava offers a huge opportunity to transform the agricultural economy and stimulate rural development, including rapid creation of employment for youth.”

The Nigerian government is right in step aiding cassava’s march towards the crop’s own green revolution, as is evident in the the Minister of Agriculture’s tweet earlier this year, and in his video interview below. See also related media story, ‘Long wait for cassava bread’.

Clearly, the ‘camel’ crop – once considered an ‘orphan’ in research  –  has travelled as far in science as in geography, and it is a precious asset to deploy for food production in a climate-change-prone world. As Emmanuel observes, cassava’s future can only be brighter!

Tanzanian groundnut researchers breaking new ground…and carrying their own crosses!

Omari Mponda

Omari Mponda

After getting a good grounding on the realities of groundnut research from Vincent, our next stop is East Africa, Tanzania, where we meet Omari Mponda (pictured). Omari is a Principal Agricultural Officer and plant breeder at Tanzania’s Agricultural Research Institute (ARI), Naliendele, and country groundnut research leader for the Tropical Legumes I (TLI) project, implemented through our Legumes Research Initiative.  Groundnut production in Tanzania is hampered by drought in the central region and by rosette and other foliar diseases in all regions. But all is not bleak, and there is a ray of hope: “We’ve been able to identify good groundnut-breeding material for Tanzania for both drought tolerance as well as disease resistance,” says Omari. Omari’s team are also now carrying their own crosses, and happy about it. Read on to find out why they are not labouring under the weight of the crosses they carry…

…we have already released five varieties…TLI’s major investment in Tanzania’s groundnut breeding has been the irrigation system… Frankly, we were not used to being so well-equipped!”

Q: How  did you go about identifying appropriate groundnut-breeding material for Tanzania?
A: We received 300 reference-set lines from ICRISAT [International Crops Research Institute for the Semi-Arid Tropics], which we then genotyped over three years [2008– 2010] for both drought tolerance and disease resistance. After we identified the best varieties, these were advanced to TLII [TLI’s sister project] for participatory variety selection with farmers in 2011–2012, followed by seed multiplication. From our work with ICRISAT, we have already released five varieties.

Harvesting ref set collection at Naliendele_w

Harvesting the groundnut reference-set collection at Naliendele. A ‘reference set’ is a sub-sample of existing germplasm collections that facilitates and enables access to existing crop diversity for desired traits, such as drought tolerance or resistance to disease or pests.

ARI–Naliendele has also benefitted from both human and infrastructure capacity building. Our scientists and technicians were trained in drought phenotyping at ICRISAT Headquarters in India. One of our research assistants, Mashamba Philipo, benefitted from six-month training, following which he advanced to an MSc specialising in drought phenotpying using molecular breeding. In his work, he is now using drought germplasm received from ICRISAT. In terms of laboratory and field infrastructure, the station got irrigation equipment to optimise drought-phenotyping trials. Precision phenotyping and accurate phenotypic data are indispensable for effective molecular breeding. To facilitate this, ARI–Naliendele benefitted from computers, measuring scales, laboratory ware and a portable weather station, all in a bid to assure good information on phenotyping. But by far, TLI’s major investment in Tanzania’s groundnut breeding has been the irrigation system which is about to be completed. This will be very useful as we enter TLIII for drought phenotyping.

 

For us, this is a big achievement to be able to do national crosses. Previously, we relied on ICRISAT…we are advancing to a functional breeding programme in Tanzania… gains made are not only sustainable, but also give us independence and autonomy to operate..We developing-country scientists are used to applied research and conventional breeding, but we now see the value and the need for adjusting ourselves to understand the use of molecular markers in groundnut breeding.”

Q: What difference has participating in TLI made?
A: Frankly, we were not used to being so well-equipped, neither with dealing with such a large volume as 300 lines! But we filtered down and selected the well-performing lines which had the desired traits, and we built on these good lines. The equipment purchased through the project not only helped us with the actual phenotyping and being able to accurately confirm selected lines, but also made it possible for us to conduct off-season trials.

We’re learning hybridisation skills so that we can use TLI donors to improve local varieties, and our technicians have been specifically trained in this area. For us, this is a big achievement to be able to do national crosses. Previously, we relied on ICRISAT doing the crosses for us, but we can now do our own crosses. The difference this makes is that we are advancing to a functional breeding programme in Tanzania, meaning the gains made are not only sustainable, but also give us independence and autonomy to operate. Consequently, we are coming up with other segregating material from what we’ve already obtained, depending on the trait of interest we are after.

Another big benefit is directly interacting with world-class scientists in the international arena through the GCP community and connections – top-rated experts not just from ICRISAT, but also from IITA, CIAT, EMBRAPA [Brazil], and China’s DNA Research Institute. We have learnt a lot from them, especially during our annual review meetings. We developing-country scientists are used to applied research and conventional breeding, but we now see the value and the need for adjusting ourselves to understand the use of molecular markers in groundnut breeding. We now look forward to TLIII where we expect to make impact by practically applying our knowledge to groundnut production in Tanzania.

Interesting! And this gets us squarely back to capacity building. What are your goals or aspirations in this area?
A: Let us not forget that TLI is implemented by the national programmes. In Africa, capacity building is critical, and people want to be trained. I would love to see fulltime scientists advance to PhD level in these areas which are a new way of doing business for us. I would love for us to have the capacity to adapt to our own environment for QTLs [quantitative trait loci], QTL mapping, and marker-assisted selection. Such capacity at national level would be very welcome. We also hope to link with advanced labs such as BecA [Biosciences eastern and southern Africa] for TLI activities, and to go beyond service provision with them so that our scientists can go to these labs and learn.

There should also be exchange visits between scientists for learning and sharing, to get up to date on the latest methods and technologies out there. For GCP’s Integrated Breeding Platform [IBP], this would help IBP developers to design reality-based tools, and also to benefit from user input in refining the tools.

California’s ‘Constant Gardener’, cowpea crusader and catapult constructor

Jeff Ehlers

Jeff Ehlers

Our guest today is Jeff Ehlers (pictured), Programme Officer at the Bill & Melinda Gates Foundation. Jeff’s an old friend of GCP, most familiar to the GCP community in his immediate past stomping grounds at the University of California, Riverside (UCR), USA, leading our research to improve cowpea production in the tropics, for which sunny California offers a perfect spot for effective phenotyping. Even then, Jeff was not new to CGIAR, as we’ll see from his career crossings. But let’s not get ahead of ourselves in narrating Jeff’s tale. First, what would high-end cowpea research have to do with crusading and catapults? Only Jeff can tell us, so please do read on!

The GCP model was a very important way of doing business for CGIAR and the broader development community, enabling partnerships between international research institutes, country programmes and CGIAR. This is particularly important as the possibilities of genomics-led breeding become even greater…If anything, we need to see more of this collaborative model.”

Growing green, sowing the seed, trading glory for grassroots
Growing up in USA’s Golden State of California, green-fingered Jeff had a passion for cultivating the land rather than laboratory samples, harbouring keen ambitions to become a farmer. This did not change with the years as he transited from childhood to adolescence. The child grew into a youth who was an avid gardener: in his student days, Jeff threw his energy into creating a community garden project ‒ an initiative which promptly caught the eye of his high school counsellor, who suggested Jeff give the Plant Science Department at UCR a go for undergraduate studies.

And thus the seeds of a positively blooming career in crop research were sown. However, remaining true to the mission inspired by his former community-centred stomping grounds, a grassroots focus triumphed over glory-hunting for Jeff, who – no stranger to rolling his sleeves up and getting his fingers into the sod – found himself, when at the University of California, Davis, for his advanced studies, embarking on what was to become a lifelong undertaking, first at the International Institute of Tropical Agriculture (IITA) and then at UCR, dedicated to a then under-invested plant species straggler threatening to fall by the research world’s wayside. With a plethora of potential genomic resources and modern breeding tools yet to be tapped into, Jeff’s cowpea crusade had begun in earnest…

GCP’s TLI was essential in opening that door and putting us on the path to increased capability – both for cowpea research enablement and human capacity”

Straggler no more: stardom beckons, and a place at the table for the ‘orphan’
And waiting in the wings to help Jeff along his chosen path was the Generation Challenge Programme (GCP), which, in 2007, commissioned Jeff’s team to tackle the cowpea component of the flagship Tropical Legumes I (TLI) project, implemented by GCP under the Legumes Research Initiative. TLI is mainly funded by the Bill & Melinda Gates Foundation. The significance of this project, Jeff explains, was considerable: “The investment came at a very opportune time, and demonstrated great foresight on the part of both GCP and the Foundation.” Prior to this initiative, he further explains, “there had been no investment by anyone else to allow these orphan crops to participate in the feast of technologies and tools suddenly available and that other major crops were aggressively getting into. Before GCP and Gates funding for TLI came along, it was impossible to think about doing any kind of modern breeding in the orphan grain legume crops. GCP’s TLI was essential in opening that door and putting us on the path to increased capability – both for cowpea research enablement and human capacity.”

Left to right: Wellington Muchero, Ndeye Ndack Diop (familiar, right?!), Raymond Fenton, Jeff Ehlers, Philip Roberts and Timothy Close in a greenhouse on the UCR campus, with cowpeas in the background. Ndeye Ndack and Jeff seem to love upstaging each other. She came to UCR as a postdoc working under Jeff, then she moved to GCP, with oversight over the TLI project, thereby becoming Jeff's boss, then he moved to the Foundation with oversight over TLI. So, what do you think might be our Ndeye Ndack's next stop once GCP winds up in 2014? One can reasonably speculate....!

So, what do you think might be our Ndeye Ndack’s next stop once GCP winds up in 2014? One can reasonably speculate….!

Of capacity building, genomics and ‘X-ray’ eyes
This capacity-building cornerstone – which, in the case of the TLI project, is mainly funded by the European Commission – is, says Jeff, a crucial key to unlocking the potential of plant science globally. “The next generation of crop scientists ‒ particularly breeders ‒ need to be educated in the area of genomics and genomics-led breeding.”

While stressing the need for robust conventional breeding efforts, Jeff continues: ”Genomics gives the breeder X-ray eyes into the breeding programme, bringing new insights and precision that were previously unavailable.”

In this regard, Jeff has played a leading role in supporting skill development and organising training for his team members and colleagues across sub-Saharan Africa, meaning that partners from Mozambique, Burkina Faso and Senegal, among others, are now, in Phase II of the TLI project, moving full steam ahead with marker-assisted and backcross legume breeding at national level, thanks to the genotyping platform and genetic fingerprints from Phase I of the project. The genotyping platform, which is now publicly available to anyone looking to undertake marker-assisted breeding for cowpeas, is being widely used by research teams not only in Africa but also in China. Thanks in part then to Jeff and his team, the wheels of the genomics revolution for cowpeas are well and truly in motion.

Undergoing the transition from phenotypic old-school plant breeder to modern breeder with all the skills required was a struggle…it was challenging to teach others the tools when I didn’t know them myself!…without GCP, I would not have been able to grow in this way.”

Talking about a revolution, comrades-in-arms, and a master mastering some more
But as would be expected, the road to revolution has not always been entirely smooth. Reflecting on some of the challenges he encountered in the early TLI days, and highlighting the need to invest not only in new students, but also in upgrading the existing skills of older scientists, Jeff tells of a personal frustration that had him battling it out alongside the best of them: “Undergoing the transition from phenotypic old-school plant breeder to modern breeder with all the skills required was a struggle,” he confides, continuing: “It was challenging to teach others the tools when I didn’t know them myself!”

Thus, in collaboration with his cowpea comrades from the global North and South, Jeff braved the steep learning curve before him, and came out on the other side smiling – an accomplishment he is quick to credit to GCP: “It was a very interesting and fruitful experience, and without GCP, I would not have been able to grow in this way,” he reveals. Holding the collaborative efforts facilitated by the broad GCP network particularly dear, Jeff continues: “The GCP model was a very important way of doing business for CGIAR and the broader development community, enabling partnerships between international research institutes, country programmes and CGIAR. This is particularly important as the possibilities of genomics-led breeding become even greater…If anything, we need to see more of this collaborative model.”

GCP’s Integrated Breeding Platform addresses the lack of modern breeding skills in the breeding community as a whole, globally…The Platform provides extremely valuable and much-needed resources for many public peers around the world, especially in Africa…”

One initiative which has proved especially useful in giving researchers a leg up in the mastery of modern breeding tools, Jeff asserts, is GCP’s Integrated Breeding Platform (IBP): “IBP addresses the lack of modern breeding skills in the breeding community as a whole, globally. By providing training in the use of genomic tools that are becoming available, from electronic capture of data through to genotyping, phenotyping, and all the way to selective decision-making and analysis of results, IBP will play a critical role in helping folks to leverage on the genomics revolution that’s currently unfolding,” Jeff enthuses, expanding: “The Platform provides extremely valuable and much-needed resources for many public peers around the world, especially in Africa where such one-off tools that are available commercially would be otherwise out of reach.”

Conqueror caparisoned to catapult: life on the fast lane and aiming higher
Well-versed in conquering the seemingly unobtainable, Jeff shares some pearls of wisdom for young budding crop scientists:”Be motivated by the mission, and the ideas and the science, and not by what’s easy, or by what brings you the most immediate gratification,” he advises, going on to explain: “Cowpeas have been through some really tough times. Yet, my partners and I stuck it out, remained dedicated and kept working.” And the proof of Jeff’s persistence is very much in the pudding, with his team at UCR having become widely acclaimed for their success in catapulting cowpeas into the fast lane of crop research.

It was a success that led him to the hallways of the Bill & Melinda Gates Foundation, where, after two decades at UCR, Jeff is currently broadening his legume love affair to also embrace beans, groundnuts, chickpeas, pigeonpeas and soya beans.

February 2014: Jeff donning his (now-not-so-)new Gates hat and on the road, visiting ICRISAT in India. Behind him is an ICRISAT experimental field of early-maturing pigeonpeas. Here, our conquering crusader is ‘helmeted’ in an ICRISAT cap, even if not horsed and caparisoned for this ‘peacetime’ pigeonpea mission!

On his future professional aspirations, he says: “The funding cut-backs for agriculture which started before 1990 or so gutted a lot of the capacity in the public sector, both in the national programmes in Africa but also beyond. I hope to play a role in rebuilding some of the capacity to ensure that people take full advantage of the technical resources available, and to enable breeding programmes to function at a higher level than they do now.”

Next to Jeff is Emmanuel Monyo, the coordinator of the Tropical Legumes II (TLII) project – TLI’s twin – whose brief is seed multiplication. TLII is therefore responsible for translating research outputs from TLI into tangible products in the form of improved legume varieties.

Whilst it’s been several years since he donned his wellington boots for the gardening project of his youth, what’s clear in this closing statement is an unremitting and deeply ingrained sense of community spirit – albeit with a global outlook – and a fight for the greater good that remain at the core of Jeff’s professional philosophy today.

No doubt, our cowpea champion and his colleagues have come a long way, with foundations now firmly laid for modern breeding in the crop on a global scale, and – thanks to channels now being established to achieve the same for close relatives of the species – all signs indicate that the best is yet to come!

Armin Bhuiya (pictured) is a dynamic and lively young geneticist and plant breeder, who has made huge strides in tracking crucial  genes in Bangladeshi rice landraces (or traditional farmer varieties). Armin took a ‘sandwich’ approach twinning two traits  – salt and submergence tolerance – in order to boost farmers’ yields. Her quest for salt-impervious ‘amphibian’ rice has seen her cross frontiers to The Philippines, and back to her native Bangladesh with solutions that will make a difference, borrowing a leaf along the way from the mythical submarine world of Atlantis for life under water. Using cutting-edge crop science, Armin is literally recreating out-of-this-world stuff working two elements of the ancient world – earth and water – plus that commodity that was then so prized enjoying a  premium comparable to gems: salt. Read on! 

A rice heritage, and the ‘sandwich’ saga and submarine search both begin…

“My father worked at the Bangladesh Rice Research Institute (BRRI), which basically means I grew up in rice research. You could say that I was born and bred in agriculture and this inspired me to study agriculture myself,” says Armin. As a result of these early experiences, Armin started a master’s degree in 2006 on genetics and plant breeding, specialising in hybrid rice. Ever since, rice has been her religion, following in the footsteps of her father to join the Bangladesh Rice Research Institute (BRRI).

Her other defining hallmark is her two-in-one approach. Sample this: once she completed her two-in-one master’s, Armin went on to study for a PhD in the same twin areas at Bangladesh Agricultural University. Pondering long and hard on what research would be of most practical use, she asked herself “What is the need? What research will be useful for my country and for the world?” (Editorial aside: out of this world work, apparently…)

Not content  pondering  over the question by herself, her natural two-track approach kicked in. Mulling with her colleagues from BRRI, the answer, it first seemed, was to find ways to produce salt-tolerant high-yielding rice. In Bangladesh and many other parts of South and Southeast Asia, climate change is driving up the sea level, spreading salinity further and deeper across low-lying coastal rice-fields, beyond the bounds where salt-drenched terrain has long been a perennial problem. Modern rice varieties are highly sensitive to salt. So, despite the low yields and quality, farmers continue to favour hardy traditional rice landraces that can take the heat and hit from the salt. Proceeding from this earthy farmer reality and inverting the research–development continuum, Armin needed no further thinking as the farmers showed the way to go. Her role and the difference she could make was to track the ‘treasure’ genes locked in these landraces that were transferred to high-yielding but salt-sensitive rice varieties, to fortify them against salt.

But that was not all. There’s power in numbers and consulting others, harnessing the best in diversity. In comes the two-track approach again, with Armin now turning to fellow scientists again, with the reality from farmers. Upon further consultations with colleagues, yet another fundamental facet emerged that could not be ignored. Apparently, salt-impervious rice alone would not be not enough, and here’s why. Salt and tides aside, during the rainy season inland, flash floods regularly submerge the fields, literally drowning the crop. More than 20 million hectares in South and Southeast Asia are affected – including two million hectares in coastal Bangladesh alone. The southern belt of Bangladesh is particularly affected, as modern varieties are sensitive to not only submergence but also salinity. So Armin had her work cut out for her, and she now knew that for the fruit of her labour to boost rice production in coastal regions as well (two tracks again! Inland and coastal low-lying rice-lands), what she needed to do was to work on producing high-yielding, salt-impervious, ‘amphibian’ rice that could withstand not only salinity but also submarine life. In other words, pretty much rice for a latter-day real-life rendition of the mythical Atlantis.

Armin has successfully incorporated dual tolerance to salinity and submergence in the popular Bangladeshi mega-variety BR11. This will provide the ideal salt-tolerant ‘amphibian’ rice suitable for farmers in the flood-prone salty-water-drenched swaths of southern Bangladesh.”

Through the door of opportunity
The opportunity that opened the door for Armin to fulfil her dream was a DuPont Pioneer postgraduate fellowship implemented by GCP. The competitive programme provides grants for postgraduate study in plant breeding and genetics to boost the yields of staple food crops. This fellowship took Armin to Filipino shores and the molecular breeding labs at the International Rice Research Institute (IRRI). Here she got what she terms a golden opportunity to work under the tutelage of Abdelbagi Ismail, a leading plant physiologist focusing on overcoming abiotic stresses. From him, Armin learnt how carry out the precise meticulous research required for identifying quantitative trait loci (QTLs).

Armin conducted her research with two different mapping populations, both derived from Bangladeshi landraces (Kutipatnai and Ashfal). She found a total of nine quantitative trait loci (QTLs) from one mapping population and 82 QTLs from another for tolerance to salinity stress at seedling stage (QTL is a gene locus where allelic variation is associated with variation in a quantitative trait). Incorporating these additional genes into a high-yielding variety will help to develop promising salt-tolerant varieties in future. She has also successfully incorporated QTLs for dual tolerance to salinity (Saltol) and submergence (Sub1) in the popular Bangladeshi mega-variety, BR11. Stacking (or ‘pyramiding’ in technical terms) Saltol and Sub1 QTLs in BR11 will provide the ideal salt-tolerant ‘amphibian’ rice suitable for farmers in the flood-prone salty-water-drenched swaths of southern Bangladesh.

I know what to do and what is needed… I am going to share what I learned with my colleagues at BRRI and agricultural universities, as well as teach these techniques to students”

Dream achiever and sharer: aspiring leader inspiring change
The Pioneer–GCP fellowship has given Armin the opportunity to progress professionally. But, more than that, it means that through this remarkable young scientist, others from BRRI will benefit – as will her country and region. “While I was at IRRI,” Armin says, “I trained myself in modern molecular plant-breeding methods, as I knew that this practical experience in high-tech research methods would definitely help Bangladesh. I know what to do and what is needed. I am going to share what I learned with my colleagues at BRRI and agricultural universities, as well as teach these techniques to students. It makes me very happy and my parents very proud that the fellowship has helped me to make my dream come true.”

Away from professional life, there have been benefits at home too, with these benefits delivered with Armin’s aplomb and signature style in science – doing two in one, in more ways than one. This time around, the approach has led to dual doctorates for a dual-career couple in different disciplines: “When I went to The Philippines” Armin reveals, “my husband decided to come with me, and took the opportunity to study for a PhD in development communications. So we were both doing research at the same time!”

While Armin’s research promises to make a real difference in coastal rice-growing areas, Armin herself has the potential to lead modern plant breeding at her institute, carry GCP work forward in the long term, post-GCP, and to inspire others as she herself was inspired – to make dreams come true and stimulate change. An inspired rice scientist is herself an inspiration. You will agree with us that Armin personifies Inspiring change, our favoured sub-theme for International Women’s Day this year.

Go, Armin, Go! We’re mighty proud of what you’ve achieved, which we have no doubt serves as inspiration for others!

Two peas in a pod, hand in hand, 

Elizabeth Parkes

“In the past, the assumption was always that ‘Africa can’t do this.’ Now, people see that when given a chance to get round circumstances – as GCP has done for us through the provision of resources, motivation, encouragement and training – Africa can achieve so much!…GCP has made us visible and attractive to others; we are now setting the pace and doing science in a more refined and effective manner…Building human capacity is my greatest joy….I’ve pushed to make people recognise that women can do advanced agricultural science, and do it well. To see a talented woman researcher firmly established in her career and with her kids around her is thrilling….Rural families are held together by women, so if you are able to change their lot, you can make a real mark…” –  Elizabeth Parkes, cassava researcher, Ghana

Elizabeth’s PhD is on cassava genetic diversity, combining ability, stability and farmer preference in Ghana. But for Elizabeth, it is not the academic laurels and limelight but rather, a broader vision of social justice which really drives her: “I see African communities where poverty and hunger are seemingly huge problems with no way out; I’m fortunate to be working on a crop whereby, if I put in enough effort, I can bring some solutions. My primary target group in my research is the less privileged, and women in particular have been my friends throughout. Rural families are held together by women, so if you are able to change their lot, you can make a real mark.”

 

…agricultural research was a man’s job!”

A perennial passion for cassava, and walking with giants: Elizabeth with the pick of the crop for the 2014 cassava harvest season at IITA, Ibadan, Nigeria.

A perennial passion for cassava, and walking with giants: Elizabeth with the pick of the crop for the 2014 cassava harvest season at IITA, Ibadan, Nigeria.

Prowess and prejudice: Breaking the mould and pioneering into pastures new
On first tentatively dipping her toe into the professional waters of crop science when growing up in her native Ghana, initial reactions from her nearest and dearest suggested that carving out a name for herself in her career of choice was never going to be a walk in the park: “As an only girl among eight  boys of whom three were half-siblings, and the youngest child, my father was not very amused; he thought agricultural research was a man’s job!” she recalls. Undeterred and ever more determined to turn this commonly held canard on its head, Elizabeth went on to bag a Bachelor’s degree in Agriculture, a diploma in Education, and an MPhil degree in Crop Science. During a stint of national service between academic degrees, she approached a scientist engaged in root and tuber projects at Ghana’s Council for Scientific and Industrial Research (CSIR) Crops Research Institute (CRI), offering to carry out some research on cassava, and soon establishing the institute’s first trials in Techiman, in the Brong Ahafo Region,where she was doing her national service. Recognising all the hallmarks of a great scientist, nurturer and leader, her CRI colleagues were quick to welcome this fresh talent into the fold as an Assistant Research Officer, with the full treasure trove of root tuber crops – from cassava to sweet potato to yam and cocoyam, among others – all falling under her remit. Not a bad start for the first woman to be assigned to the project!

Quickly proving herself as a fiercely cerebral researcher with a natural knack for the plant sciences, Elizabeth was encouraged by seasoned (then) GCP scientist, Martin Fregene (their paths had crossed during Elizabeth’s master’s degree thanks to research collaboration with the International Institute of Tropical Agriculture – IITA), to embark on a PhD degree with a focus on cassava. Coinciding with an era when links between Martin’s then home institute, the International Center for Tropical Agriculture (CIAT) and GCP were beginning to really take off the ground, it was a move that proved timely, and a path which Elizabeth pursued with her characteristic vigour and aplomb, climbing the GCP research ranks from multiple travel-grant recipient to a research fellow, and, more recently, to Lead Researcher for GCP’s cassava work in Ghana. Now a well established cassava connoisseur who regularly rubs shoulders with the crème de la crème of the global crop science community, Elizabeth specialises in drought tolerance and disease resistance in the GCP-related aspects of her work, whilst also turning her hand to biofortification research for GCP sister CGIAR Challenge Programme, HarvestPlus.

… it [biotechnology] was a breakthrough which Elizabeth spearheaded…”

Up, up and away! How a helping hand has led Elizabeth & Co to new professional and research heights
Life aboard the GCP ship, Elizabeth reveals, has offered a wealth of professional opportunities, both on personal and institutional levels. GCP-funded infrastructure, such as weather stations and irrigation systems, has helped to boost yields and enhance the efficiency of CRI trials, she observes. Professional development for herself and her team, she says, has been multifold: “Through our GCP work, we were able to build a lab and kick-start marker-assisted breeding – that ignited the beginning of biotechnology activities in CRI,” Elizabeth asserts.  It was a breakthrough which Elizabeth spearheaded, and which, happily, has since become run-of-the mill practice for the institute: “Now CRI scientists are regularly using molecular tools to do their work and are making cassava crosses on their own.” The positive domino effect of this change in tide cannot be underestimated: “Our once small biotechnology laboratory has evolved into a Centre of Excellence under the West Africa Agricultural Productivity Programme. Its first-class facilities, training courses and guiding hand in finding solutions have attracted countless visiting scientists, both from Ghana and internationally – this means that the subregion is also benefitting enormously.” The GCP’s Genotyping Support Service (GSS), Elizabeth affirms, has also proved an invaluable sidekick to these developments: “Through the GSS, our team learnt how to extract DNA as a first step, and later to re-enact all the activities that were initially done for us externally – data sequencing, interpretation and analysis for example – on a smaller scale in our own lab.” The collection and crunching of data has also become a breeze: “Thanks to GCP’s support, we have become a pace-setter for electronic data gathering using tablets, field notebooks and hand-held devices,” she adds.

….GCP gives you the keys to solving your own problems, and puts structures in place so that knowledge learnt abroad can be transferred and applied at home – it’s been an amazing journey!”

Ruth is one of those whose work–family balance Elizabeth celebrates. Ruth has since submitted her thesis awaiting results. As you’ll hear in the podcast below, both of Ruth’s young children have each, er, sort of ‘attended’ two big GCP events!

People power: capacity building and work–life balance
Elizabeth lights up most when waxing lyrical about the leaps and bounds made by her many students and charges through the years, who – in reaping some of the benefits offered by GCP, such as access to improved genetic materials; forging links with like-minded colleagues near and far, and, critically, capacity building – have gone on to become established and often internationally recognised breeders or researchers, with the impacts of their work posting visible scores in the fight against global food insecurity. On the primordial role of capacity building, she says: “GCP gives you the keys to solving your own problems, and puts structures in place so that knowledge learnt abroad can be transferred and applied at home – it’s been an amazing journey!” Of her female students who’ve surmounted the work–family pendulum challenge, she says: “I’ve pushed to make people recognise that women can do advanced agricultural science, and do it well. To see a talented woman researcher firmly established in her career and with her kids around her is thrilling.”

At IITA, Elizabeth continues to be an inspiration on work–life balance for women working on their PhDs, and more so for young women whose work is on cassava. In a male-dominated environment (global statistics report that women researchers are a meagre 30 percent), this inspiration is critical. .

No ‘I’ in team: tight-knit community a must for kick-starting real and sustainable solutions
As Elizabeth well knows, one swallow does not a summer make: as demonstrated by the GCP’s Communities of Practice (CoPs), she says, strength really does come in numbers: “The GCP Cassava CoP has brought unity amongst cassava breeders worldwide; it’s about really understanding and tackling cassava challenges together, and bringing solutions home.” Bolstering this unified spirit, Elizabeth continues, is the GCP’s Integrated Breeding Platform (IBP): “With the initial teething problems mainly behind us, IBP is now creating a global community and is an excellent way of managing limited resources, reducing duplication of efforts and allowing people to be more focused.” On helping scientists inundated with information to spot the wood from the trees, she says: “Over the years, lots of data have been generated, but you couldn’t find them! Now, thanks to IBP, you have sequencing information that you can tap into and utilise as and where you need to. It’s very laudable achievement!”

In the past, the assumption was always that ‘Africa can’t do this.’…GCP has made us visible and attractive to others; we are now setting the pace and doing science in a more refined and effective manner.” 

Clearly, keeping the company of giants is not new for Elizabeth (right). This giant cassava tuber is from a 2010 CRI trial crossing improved CIAT material with CRI landraces (traditional farmer varieties. The trial was part of Bright Boakye Peprah’s postgraduate work. Bright has since completed his GCP-funded masters on cassava breeding, and now a full time cassava breeder with CSIR–CRI. He is currently on study leave pursuing a PhD on cassava biofortification in South Africa. On the left is Joseph Adjebeng-Danquah, a GCP-funded PhD student whose work centres on cassava drought tolerance. Our best quote from Joseph: “It is important to move away from the all too common notion that cassava is an ‘anywhere, anyhow’ crop.”

Our best quote from Joseph: “It is important to move away from the all too common notion that cassava is an ‘anywhere, anyhow’ crop.”

Empowered and engaged: African cassava researchers reclaim the driving seat
The bedrock of GCP’s approach, Elizabeth suggests, is the facilitation of that magical much sought-after Holy Grail: self-empowerment. “When I first joined GCP,” she recalls, “I saw myself as somebody from a country programme being given a place at the table; my inputs were recognised and what I said would carry weight in decision-making.” It’s a switch she has seen gain traction at national and indeed regional levels: “In the past, the assumption was always that ‘Africa can’t do this.’ Now, people see that when given a chance to get round circumstances – as GCP has done for us through the provision of resources, motivation, encouragement and training – Africa can achieve so much!” Reflecting on the knock-on effect for African cassava researchers particularly, she concludes: “GCP has made us visible and attractive to others; we are now setting the pace and doing science in a more refined and effective manner.”

Paying it forward and sharing: Helping women, and thereby, communities
Armed with bundles of knowledge as she is, Elizabeth is a firm believer in paying it forward and sharing: “Building human capacity is my greatest joy,” she affirms, citing farmers, breeders, and a Ghanaian private-sector company as just a few of the fortunate beneficiaries of her expertise over recent years. And on sources of motivation, it is not the academic laurels or limelight but rather a broader vision of social justice which really drives her: “I see African communities where poverty and hunger are seemingly huge problems with no way out; I’m fortunate to be working on a crop whereby, if I put in enough effort, I can bring some solutions.” They are solutions which she hopes will be of lasting service to those closest to her heart: “My primary target group in my research is the less privileged, and women in particular have been my friends throughout. Rural families are held together by women, so if you are able to change their lot, you can make a real mark.”

We’re in a blessed and privileged era where cassava, an ancient and once orphan crop, is now receiving lots of attention… I encourage young scientists to come on board!”

Inspired, and inspiring: nurturing budding cassava converts, and seizing opportunities for impact
In terms of future horizons, Elizabeth – who after more than two decades of service at CRI is currently on leave of absence at IITA where she’s working on biofortification of cassava – hopes to thereby further advance her work on cassava biofortification, and perhaps later move into a management role, focusing on decision-making and leading agricultural research leaders with monitoring and evaluation specifically to “ensure that the right people are being equipped with skills and knowledge, and that those people are in turn teaching others.” She is also confident that any young, gifted researcher with an eye on the prize would be foolhardy to overlook what Elizabeth views as a golden opportunity for creating meaningful and lasting impacts: “We’re in a blessed and privileged era where cassava, an ancient and once orphan crop, is now receiving lots of attention. Every agricultural research lead we have in Africa is there to be seized – I encourage young scientists to come on board!” A clear and convincing clarion call to budding breeders or potential cassava converts if ever there was one…. who wants in, in this love-match where cassava and capacity building are truly two peas in a pod?

Like meets like in a fair match: Our cassava champion in a male-dominated environment, Elizabeth, meets her match in Farmer Beatrice who refused to take no for an answer, and beat Elizabeth hands down. Listen to this!

Starters, palate and pocket
Marie-Noëlle opens the feast with a short but succulent starter, as she explains succinctly in 30 seconds just how rice is becoming a staple in Africa. In the second course, Marie-Noëlle chews over the questions concerning combatting constraints and boosting capacity in rice research in Africa.

The third course is pleasing to the eye, the palate and the pocket! Marie-Noëlle truly sells us the benefits of molecular breeding, as she extolls the virtues of the “beauty of the marker”. Why should you use molecular tools? They’ll save you time and money!

Rice as beautiful as the markers Marie-Noëlle uses in molecular breeding

Wherefore art thou, capacity building in rice research in Africa?
The Shakespearean language alludes to the why of capacity building in Africa, as does video episode number four, which also tackles the what of this fourth dish in our banquet. Course number five offers the viewer a light look at how capacity building in Africa is carried out.

In the 6th course, Marie-Noëlle takes us out of this world and into MARS: she teaches us that ‘two are better than three’, as she explains how the novel bi-parental marker-assisted recurrent selection (MARS) method is proving effective when it comes to duelling with drought, the tricky three-headed monster comprising physiological, genetic and environmental components.

Blooming rice in the field

Of stars and scoundrels
The 7th and final course offers us a riveting tale of heroes and villains, that is, many heroes and a single villain! Our rice raconteuse, Marie-Noëlle, praises the power of the team, as a crew from cross-continental countries come together, carefully characterise their combatant (drought), before striking with environment-specific drought-tolerant varieties! AfricaRice’s project partners are Burkina Faso’s Institut de l’environnement et de recherches agricoles (INERA); Mali’s Institut d’économie rurale (IER); and Nigeria’s National Cereals Research Institute (NCRI). Collaborators are France’s Centre de coopération internationale en recherche agronomique (CIRAD); the International Center for Tropical Agriculture (CIAT); and the International Rice Research Institute (IRRI).

We hope these tasty teasers are enough to whet your appetite – you can savour each of the courses individually à la carte, or, for those with a daring desire to try the ‘all you can eat’ buffet for true rice gourmets, all seven courses are presented as a single serving on our YouTube channel.

A new breed of Workbench – Introducing the Breeding Management System

Mark Sawkins

Mark Sawkins

Mark the man in the middle, and of the markers…

Today, we talk to Mark Sawkins (pictured), the ‘middleware’ man in our Integrated Breeding Platform (IBP) so to speak, seeing as he is the human ‘interface’ between crop breeders on the one hand, and the developers of our Integrated Breeding Platform (IBP) on the other hand. Mark is the ‘bridge’ that connects IBP users and IBP developers – a special position which gives him a privileged and fascinating perspective on both sides of the coin, with a dash of public–private sector pragmatic partnership thrown in too. Here’s more on Mark, in this dispatch from and on his special perch on the bench…

Bridge to bench, abuzz on BMS: A ‘tinker’ at Toulouse…
Mark Sawkins is always busy tinkering away on his Workbench at his base in Toulouse in southern France. It’s not your traditional wooden workbench, covered in sawdust, soil or splattering of paint. Nor is it one carpeted in documents lit by the warm glow of a computer monitor. In fact, the workbench Mark is working on is virtual, having no physical form and residing solely online, or on a user’s computer, once downloaded.

Known as the Breeding Management System (BMS) the Workbench, comprising software tools linked to a database for access to pedigree, phenotypic and genotypic data, has been developed by GCP’s Integrated Breeding Platform. The BMS has what a crop breeder would require to conduct an analysis of phenotypic and genotypic data generated as part of a crop-breeding or evaluation experiment, covering a broad spectrum of needs from conventional breeding to advanced molecular breeding applications. Version 2 of the Breeding Management System was released just last month.

… it [BMS] will be of most help to breeders both in the public and private sector in Africa and Asia who, up to now, have had little or no access to tools and data to allow them to shift gears in their breeding programme…The BMS has a lot of tools and all the foundational data necessary for a breeder’s routine day-to-day activities…The BMS is also anticipated to have enormous positive impact on food security in developing countries in the years ahead, enabling crop breeders to evaluate their progenies using the most sophisticated statistical methods available”

A hands-on BMS orientation workshop underway for breeders in Africa, held in Ethiopia in July 2013 under the auspices of the GCP-funded cassava breeding community of practice. Standing, Yemi Olojode, of Nigeria’s National Root Crops Research Institute (NRCRI), Umidike, who was one of the trainers.

Previously known as the Integrated Breeding Workflow System (IBWS), the BMS incorporates both statistical analysis tools and decision-support tools. The tools are assembled in a way that data can flow seamlessly from one application to the next in tandem with the various stages of the crop-breeding process. It allows the breeder to accurately collect, securely store and efficiently analyse and synthesise their data on a local private database, and also share, or compare, their data with other breeders via a central public crop database.

“The BMS has a lot of tools and all the foundational data necessary for a breeder’s routine day-to-day activities,” explains Mark, a plant geneticist who joined IBP in 2011. “Any breeder can use it, but it will be of most help to breeders both in the public and private sector in Africa and Asia who, up to now, have had little or no access to tools and data to allow them to shift gears in their breeding programme, particularly in adopting modern breeding practices, including the use of molecular markers.”

The BMS is also anticipated to have enormous positive impact on food security in developing countries in the years ahead, enabling crop breeders to evaluate their progenies using the most sophisticated statistical methods available, and make selections on which lines to advance to the next phase of development in the progression towards more productive and resilient crop varieties.

Phenotyping and field trials are becoming the most expensive part of the breeding process… The biggest hurdle in the public sector in the past was the massive investment required to set up genotyping laboratory facilities… outsourcing, we believe, will help convince breeders to consider integrating molecular techniques into their breeding programmes”

Why integrated breeding?
For almost 30 years, the private sector has been implementing molecular-breeding approaches in developing more productive and resilient crops. These approaches allow breeders to select for plant characteristics (traits) early in the breeding process and then test whether a plant has the targeted trait, which they cannot visually identify.

“Phenotyping and field trials are becoming the most expensive part of the breeding process,” says Mark. “Using molecular markers is a way to reduce the investment in that process. By using markers, early in the development of a given crop line, you can reduce the number of plants you need to grow and test, reducing the time and cost associated with field trials.”

Mark hopes that the Workbench will in time enable breeders, in under-resourced public breeding institutes to access some of the leading molecular-marker databases, and make use of the markers therein for the desired traits they are breeding for, along with technical support from molecular breeders to guide them in making their breeding decisions.

“The biggest hurdle in the public sector in the past was the massive investment required to set up genotyping laboratory facilities,” explains Mark “but now there are plenty of professional service providers that people can send their samples to and get back good results at a very reasonable cost. This time- and cost-saving reality of outsourcing, we believe, will help convince breeders to consider integrating molecular techniques into their breeding programmes.”

We are currently conducting a three-year course to train scientists from national programmes in West and Central Africa, East and Southern Africa and South and Southeast Asia, who we hope will promote and support the adoption of modern breeding in their institutes and countries.”

Running with champions
Mark knows that giving breeders the tools and means to integrate molecular breeding into their programmes is one thing. To actually have them adopt them is another. But he has a plan.

In keeping with the core mission of GCP, which is to build sustainable capacity in developing-country breeding programmes, Mark proposes to recruit and train selected breeders in molecular-breeding techniques and set them up as champions and advocates for their particular crop or region.

Marker implementation methods can be varied but the tools required need to help the breeder make a quick informed decision on what to take forward to the next generation: What plants need to be crossed? Which plants should be kept and which ones discarded? The decision-support tools provided by the IB Workbench will help the breeder make these decisions.

“We are currently conducting a three-year course to train scientists from national programmes in West and Central Africa, East and Southern Africa and South and Southeast Asia, who we hope will promote and support the adoption of modern breeding in their institutes and countries,” Mark enthusiastically explains. The three-year training programme is known as the Integrated Breeding Multiyear Course (IB–MYC). Mark continues, “We believe that people will be more willing to listen to someone who is right there on the ground, whom they know and trust and can easily get in contact with if they need help.”

While the champions concept is still in its infancy, Mark believes it has real merit but must overcome two major barriers – time and confidence. “Identifying the champions won’t be hard,” he observes, “What will be hard is getting them to add this extra task to their already busy agenda. It will require buy-in from management at the institutional level to enable the champions to carry out their mission. It will also be individually hard for each champion, who will only be successful when they have the confidence in their own integrated breeding and extension skills. This confidence would be the thing that would really help sell the message.”

Engaging the private sector
Mark oversees the design, testing and deployment of the system that underpins the BMS, ensuring that both the system and the tools embedded in it are easy to use and meet the needs and expectations of the breeders. However, he and his team have had some trouble getting feedback on the system from the breeders it is intended for, due to their inexperience with such tools and systems. That is why he has called on his private-sector contacts, developed when he was at Syngenta where he worked for five years prior to his current assignment.

“We hope to show them what we’ve been doing in IBP with the Workbench, and hopefully get some private-sector buy-in and see how they can help us – not in developing tools, but with feedback on functionality and usability of the tools we are developing,” he explains. “We don’t have a core set of breeders who are routinely using markers in their breeding programme amongst the partners we are working with on the IBP project. So we are tapping into the private sector which has teams of molecular breeders who are more familiar with the types of breeding workflows and tools we are developing. We’re hoping that we can take advantage of their knowledge and experience to get some really useful feedback, which we will use to improve the usability and effectiveness of our tools.”

To maximise adoption and use, GCP has been actively engaged in extensive capacity building, and this will be reinforced with a comprehensive awareness-creation and communication effort immediately before and after a projected mid-year release of a newer BMS version incorporating the all-essential user feedback. The impact of the analytical pipeline in developing countries will be particularly enhanced with the availability of efficient user support services, which Mark will be overseeing.
