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.”

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!

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.

For this ‘IBP story-telling season’, our next stop is  very fittingly Africa, and her most populous nation, Nigeria. Travel with us!

Having already heard the Integrated Breeding Platform (IBP) story on data from Arllet (spiced with a brief detour through Asia’s sun-splashed rice paddies), and on IBP’s Breeding Management System from Mark (where we perched on a corner on his Toulouse workbench of tools and data), we next set out to get an external narrative on IBP, and specifically, one from an IBP user. Well, we got more than we had bargained for from our African safari…

An agronomist by training with a couple of decades-plus experience, he not only works closely with breeders and other crop scientitsts, but is also a research coordinator and data manager. As you can imagine, this made for a rich and insightful conversation, ferrying us far beyond the frontiers of Yemi’s base in Nigeria, to the rest of West Africa,  further out to Africa , and as far afield as Mexico, in his travels and travails with partners. We now bring to you some of this captivating conversation…

Yemi  has been working for the last 23 years (since 1991) at Nigeria’s National Root Crops Research Institute (NRCRI) at Umudike in various capacities. After heading NRCRI’s Minor Root Crops Programme for 13 years, he was last year appointed Coordinator-in-Charge of the Cassava Research Programme.

But his involvement in agriculture goes much further back than NRCRI: Yemi says he “was born into farming”. His father, to whom he credits his love for agriculture, was a cocoa farmer. “I enjoy seeing things grow. When I see a field of crops …what a view!” Yemi declares.

Yemi is also the Crop Database Manager for NRCRI’s GCP-funded projects. He spent time at GCP headquarters in Mexico in February 2012 to sharpen his skills and provide user insights to the IBP team on the cassava database, on the then nascent Integrated Breeding Fieldbook, and on the tablet that GCP was considering for electronic field data collection and management.

To meet the farmers’ growing need for improved higher-yielding and stress-tolerant varieties, plant breeders are starting to incorporate molecular-breeding techniques to speed up conventional breeding.

But for this to happen effectively, cassava breeders require consistent and precise means to collect and upload research and breeding data, and secure facilities to upload that data into the requisite databases and share it with their peers. Eighty percent of farmers in Africa have less than a hectare of land – that’s roughly two football fields! With so little space, they need high-value crops that consistently provide them with viable yields, particularly during drought. For this reason, an increasing number of Nigerian farmers are adopting cassava. It is not as profitable as, say, wheat, but it has the advantage of being less risky. The Nigerian government is encouraging this change and is implementing a Cassava Transformation Agenda, which will improve cassava markets and value chains locally and create a sustainable export market. All this is designed to encourage farmers to grow more cassava.

Enter GCP’s Integrated Breeding Platform (IBP), which has been working closely with NRCRI and other national breeding programmes to develop the right informatic tools and support services for the job. The International Cassava Information System (ICASS), the Integrated Breeding Fieldbook and the tablet are all part of the solution, backed up by a variety of bioinformatic tools for data management, data analysis and breeding decision support that have been developed to meet the specific needs of the users.

I enjoy working with the team. They pay attention to what we as breeders want and are determined to resolve the issues we raise”

The database and IB Fieldbook
“When I received the tablet I was excited! I had heard so much about it but only contributed ideas for its use through Skype and email,” Yemi remembers, echoing a sentiment that is frequently expressed by many partners who have been introduced to the device. “I experimented with the Integrated Breeding Fieldbook software focusing on pedigree management, trait ontology management, template design ‒ testing how easy it was to input data into the program and database.”  Yemi noted a few problems with layout and data uploading and suggested a number of additional features. The IBP Team found these insights particularly useful and worked hard to implement them in time for the 2nd Scientific Conference of the Global Cassava Partnership for the 21st Century (GCP21 II), held in Kampala, Uganda, in June, 2012.

“I enjoy working with the team. They pay attention to what we as breeders want and are determined to resolve the issues we raise,” says Yemi. He believes the IB FieldBook and the tablet, on which it runs, will greatly benefit breeders all over the world, but particularly in Africa. “At the moment, our breeders and researchers have to write down their observations in a paper field book, take that book back to their computer, and enter the data into an Excel spreadsheet,” he notes. “We have to double-handle the data and this increases the possibility of mistakes, especially when we are transferring it to our computers. The IB Fieldbook will streamline this process, minimising the risk of making mistakes, as we enter our observations straight into the tablet, using specified terms and parameters, which will upload all the data to the shared central database when it’s connected to the internet.”

The whole room was wide-eyed and excited when they first saw the tablets”

Bringing the tablet to Africa
After his trip to Mexico, Yemi was concerned that some African breeders would be put off using the IB Fieldbook and accompanying electronic tablet because both require some experience with computers. “I found the tablet and the FieldBook quite easy to use because I’m relatively comfortable with computers,” says Yemi. “The program is very similar to MS-Excel, which many breeders are comfortable with, but I still thought it would be difficult to introduce it given that computer literacy across the continent is very uneven.”

At the GCP21 II meeting in Uganda, Yemi helped the IBP team run IB Fieldbook workshops for plant breeders from developing countries, with an emphasis on data quality and sharing. “The whole room was wide-eyed and excited when they first saw the tablets. They initially had trouble using them and I thought it was going to be a very difficult workshop, but by the end they all felt confident enough to use them by themselves and were sad to have to give them back!”

They … go back to their research institutes and train their colleagues, who are more likely to listen and learn from them than from someone else.”

Providing extra support, cultivating trust
Yemi recounts that attendees were particularly pleased when they received a step-by-step ‘how-to’ manual to help them train other breeders in their institutes, with additional support to be provided by the IBP or Yemi’s team in Nigeria. “They were worried about post-training support,” says Yemi. “We told them if they had any challenges, they could call us and we would help them. I feel this extra support is a good thing for the future of this project, as it will build confidence in the people we teach. They can then go back to their research institutes and train their colleagues, who are more likely to listen and learn from them than from someone else.”

In developing nations, it is important that we share data, because we don’t all have the capacity to carry out molecular breeding at this time, and data sharing would facilitate the dissemination of the benefits to a wider group”

Sharing data to utilise molecular breeding
Yemi asserts that incorporating elements of molecular breeding has helped NRCRI a great deal. With conventional breeding, it would take six to 10 years to develop a variety before release, but with integrated breeding (conventional breeding that incorporates molecular breeding elements) it is possible to develop and release new varieties in three to four years ‒ half the time. Farmers would hence be getting new varieties of cassava that will yield 20‒30 percent more than the lines they are currently using in a much shorter time.

“In developing nations, it is important that we share data, because we don’t all have the capacity to carry out molecular breeding at this time, and data sharing would facilitate the dissemination of the benefits to a wider group,” says Yemi. “I enjoy helping people with this technology because I know how much it will make their job easier.”

Arllet Portugal

Today, we chit-chat with Arllet Portugal (pictured) on crop research data management. Arllet’s greatest daily challenge is convincing crop breeders and other crop researchers that their research data are just as important as their core research work. She also educates us on what she means by ‘SHARP’ data management. But first, a little background on Arllet…

Transitions, travels and tools
Plant breeding is in Arllet Portugal’s blood. Her father (now retired), one of the original field staff of the International Rice Research Institute (IRRI) at Los Baños in The Philippines, nurtured it in her from a tender age. It’s easy to picture him sharing fascinating tales daily with his family upon coming home, after a day of hard work in sun-splashed paddies where he nurtured mysterious and exotic new lines of rice which he was told may hold the solution to world hunger.

“He loved what IRRI stood for and admired the research they did,” reminisces Arllet. “I think he hoped one day he would have a son or daughter working alongside the researchers, so I guess I fulfilled that wish!” She adds “His IRRI stories still continue to this day, and I have learnt much from him which continues to give me deeper insights in my work and interactions with crop scientists.”

Having lived most of her life under the canopy of IRRI, including 12 years working as a database administrator at the Institute, she decided it was time for a change, and she spread her wings – an adventure that would take her across the oceans, pose new challenges, and plunge her deeper into agricultural research beyond IRRI’s mandate crop, rice. So, in 2009, she packed her bags and headed to Mexico, having accepted a position as a crop informatician for wheat at the International Maize and Wheat Improvement Center (CIMMYT), and then moving over to GCP the following year as Informatics Coordinator, and later on Data Management Leader of GCP’s Integrated Breeding Platform (IBP).

The Platform is a one-stop shop for crop information, informatics tools and services designed to propagate and support the application of modern approaches to crop breeding, particularly targeting developing countries.

We are trying to show breeders that their ‘system’ can be enhanced and streamlined if they enter data straight into a computer when they’re in the field and then upload them into an online database.” 

Gunning for a digital data revolution: The challenge of changing mindsets
Arllet’s greatest daily challenge is convincing crop breeders and other crop researchers that their research data are just as important as their core research work, and they should therefore dedicate as much time, energy and resources to managing data.

“Like everyone else, most plant breeders tend to be generally comfortable with the ‘systems’ that they and their predecessors have always used,” says Arllet. “For plant scientists, this often consists of recording results using pen and paper when they are out in the field, then coming back to their office and either filing those paper records as is, or re-entering the data into a basic Excel spreadsheet that is for their eyes only. They will then pull these data out when they want to compare them with their previous data.”

Arllet explains that this age-old system is not necessarily wrong, but it wastes valuable time, is insecure and limits the capacity of breeders to efficaciously reuse and also share their data with colleagues – a practice by which they would help each others’ work. “We are trying to show breeders that their ‘system’ can be enhanced and streamlined if they enter data straight into a computer when they’re in the field and then upload them into an online database,” she says.

Walking with giants…” 

Dealing with data: maximising efficiency, security, value and sharing
“These data can then be better secured and managed for their benefit and that of other researchers doing similar or related work, in essence increasing their working capacity. They would also have access to the most current analytical tools to verify their results and do their research more efficiently.”

Arllet explains that such improved systems have been in place for decades in the developed world, particularly within the private sector but not as prevalent in the developing world or public sector. This is largely attributable to the high cost of the equipment and informatics tools, and a lack of personnel with the appropriate skills to make use of the tools.

Through a collaborative effort bringing together a wide array of partners, with funding primarily from the Bill & Melinda Gates Foundation, supplemented by the European Commission and the United Kingdom’s Department for International Development, IBP is working to overcome some of these barriers. With the release of the Integrated Breeding (IB) FieldBook, the foundational informatics tool for the proposed system, Arllet believes a giant step has been made towards achieving this objective.

Breeders will be able to use it to plan their trials from start to finish”

What is the IB FieldBook?
The IB FieldBook is a user-friendly computer program that facilitates the design of field trials and produces electronic field-books, field plans and labels. It collects together – in a single application – all the basic tools that a plant breeder requires for these diverse but intertwined functions.

“Breeders will be able to use it to plan their trials from start to finish,” says Arllet. “This is important as it will, for example, keep track of all the identities of plant crosses, minimising the chance that the breeder, or assisting technician, will record the data incorrectly, while emphasising the importance of accurate data for correct crop-breeding decisions.”

Live demonstration: Taking the tablet through the paces at a training workshop for research technicians in January 2012. The regional workshop for West Africa (in French and English) was hosted by L’Institut d’économie rurale (IER) at Sotuba, Mali. A similar workshop was held in Ethiopia in English for the Eastern and Southern Africa region.

She and her team have been conducting training workshops on data management for breeders at which they demonstrate the IB FieldBook and the use of handheld electronic devices (such as tablets) for data collection, which breeders can conveniently take to the field with them and directly enter the phenotyping data they would normally capture in paper field-books.

Tablets and feedback
“The training has been challenging but fun,” says Arllet. “When we present the breeders with a tablet at the start of the exercise, they get really excited. It takes a while for them to learn how to use it, but once they do, they see how this technology could save them time and reduce the risk of mistakes. It’s a little sad for them and for us though when we have to take the tablets back at the end of the exercise, as demand always outstrips supply. We have however distributed around 200 tablets to breeders, university academic staff, researchers and postgraduate students of plant breeding. Majority of the recipients are from Africa and Asia. And the good news is that,  as a result, some of the institutes and programmes the recipients come from have gone ahead to purchase more units for themselves.”

Arllet observes that the workshops have not only allowed her team to educate breeders and build awareness, but also to receive valuable feedback on how the IB FieldBook could be improved to make it even better, and learn what other tools breeders need. “Based on this feedback, we worked on the IB FieldBook version 4, which was released in June 2013, as well as on a number phenotypic and genotypic data management tools to incorporate into both the FieldBook and the primary crop databases.”

‘SHARP’ data – shareable, available, reusable and preservable.

SHARP and secure data management
Plant breeders are collaborating more often than they used to, and also drawing much more on specialised experts for each stage of the crop variety development chain. These experts are able to verify the data to make sure they are correct, do their job quickly and pass the data onto the next expert, an economical resource- and time-efficient process. However, as Arllet explains, consistent and secure data management is key to the success of these collaborations.

For Arllet, data that are properly managed are ‘SHARP’ – shareable, available, reusable and preservable. “By collecting data in a consistent format, uploading them to a secure database with easily identifiable tags, and making them available to other researchers, the data will be more accessible to partners, enable reliable analysis and conclusions, be more likely to be reused, and most importantly, save time and money. For example, breeders who share their data on the IBP database will receive support from researchers outside of their own breeding programme and enlist the help of experts and specialists  they require for particular tasks,” says Arllet. “This includes access to, say, a molecular biologist in Europe or Asia for the breeder in Africa or America who may need that kind of specialist help, for example.”

Arllet and her team of four consultants are currently helping breeders from all around the world upload their historical research data into the central crop databases of the Integrated Breeding Platform, a massive task given the issues of trust, language barriers, slow internet connections, inadequate computer skills and the sheer volumes of the data. However, these are challenges that are becoming easier to handle with greater awareness and the enthusiasm that comes with that.

What next, and what difference will it make?
Adoption and broad use of the FieldBook will of course also make the process easier in the future, enabling a single step uploading of phenotypic data – hence setting breeders free to get on with their work without the wastefulness of having to enter and re-check the data multiple times.

“What it all means is that we will facilitate the more rapid and efficient development of higher-yielding  more stress-tolerant crops that can benefit the farmers and the people they feed,” says Arllet, “and that is the ultimate goal of a plant breeder’s work.”
