Beyond chickpeas to embrace beans, chickpeas, groundnuts and pigeonpeas

As 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.

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.

Paul (left) in the field. The crop is chickpeas of course!

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!

Finish line for the Integrated Breeding Multiyear Course (IB–MYC)

Capacity building, Integrated Breeding Platform 4 Responses »

Long legs: our longest running capacity-building marathon’s end is in sight and a new breed of breeders is ready and set to go

As we ‘speak’, the Integrated Breeding Multiyear Course (IB–MYC) is in its final session, reaching its close after three intensive years. This last gathering runs from 3rd to 14th November 2014, and as always is hosted by our partners IAMZ–CIHEAM (the Mediterranean Agronomic Institute of Zaragoza, Spain). IB–MYC is unusual in its approach, but by taking a risk and investing in long-term in-depth training, GCP has shown that IB–MYC is a powerful model for capacity building with profound impact. Congratulations to our marathon runners as they approach the finish line… and all the best for an ‘integrated breeding’ future!

Breeders develop new varieties of crop through several methods. IBP has developed new varieties of breeders through the IB-MYC programme.”
— Johnson Adedayo Adetumbi: IB–MYC participant, research fellow at the Institute of Agricultural Research & Training (IAR&T), Obafemi Awolowo University, Nigeria, and breeder working on cowpeas, kenaf, maize and soya beans

IB–MYC: integrated, intensive, incomparable

IB–MYC differed from most other courses in two important ways, both reflected in its name: its ‘integrated breeding’ curriculum and its ‘multiyear’ timescale. Implemented by GCP’s Integrated Breeding Platform (IBP), the course aimed to empower breeders in developing countries to adopt molecular-breeding techniques. The ‘integrated’ approach to making this happen meant equipping students not only with the latest knowhow on molecular breeding itself, but also hands-on training in and effective tools for data management and analysis.

Course participant Samuel Adelowo Olakojo, Head of the Cereals Improvement Programme at IAR&T and maize breeder, is an enthusiast of IBP’s Breeding Management System (BMS). “My perception about data management is that it helps the breeder to plan their work very easily without stress. The time you take in thinking how to fashion out the design of the trials – you can actually get that done very quickly, very precisely,” he says. “Secondly… after you have produced your output, with minimal editing you can transfer your data to the preparation platform for publishing it. You don’t have to sit down writing everything again,” he adds. “The presentation that comes out of it now seems more graphical. And when you present reports in a graphical, pictorial form… people are enlightened, quickly.”

Since IB–MYC began in August 2012, the participants have each received two weeks of intensive face-to-face training per year. The participants were divided between three annual training sessions, broadly reflecting the three target regions for the course of Eastern and Southern Africa, West and Central Africa, and South and Southeast Asia. In between these sessions they were expected to work on assignments and project, with ongoing in-depth support including online resources from IBP. While well-supported, it was a demanding course, with students expected to pass each year and complete their assignments as a precondition to proceeding to the next year.

More than forty participants came together in November 2014 for the final IB–MYC training session, hosted by IAMZ. For more photos, see the IAMZ Facebook page.

Taking the slow train to knowledge that sticks

Just as for the participants, this three-year course was also a major commitment for GCP, and – being unlike anything that had gone before – a risky investment of funds and efforts. However, this long-distance marathon has had some special advantages over the quick sprints of more conventional training courses, whose length is normally measured in weeks.

Rather than simply imparting knowledge that is forgotten as quickly as it is learnt, the practical focus, ongoing support and extended time-frame of IB–MYC ensured that participants were able to test and see the value of what they were learning within their own breeding activities, leading them to adopt useful technologies, tools and practices as an integral part of their work – and, it is hoped, becoming advocates, trainers and mentors themselves. Furthermore, as trainees have got to know each other and build relationships over the years, they have woven true communities of practice, springboards for sharing information and working together into the future.

Of course, not everyone has made it to the finish line. A few participants have dropped out over the years as they have changed jobs and directions, and some have even flunked the course. But the great majority have stayed the distance, and with both trainers and trainees convinced of IB–MYC’s value.

Seeds for the future in IB–MYC’s IAMZ roots

Not least of the relationships that have flourished during the course is GCP’s partnership with IAMZ, which also contains the seeds of one of the ways IB–MYC will live on into the future, after GCP’s planned close in December 2014. “We are working with IAMZ to continue that collaboration through IBP,” says Ndeye Ndack Diop, GCP’s Capacity Building Leader. “IAMZ has decided to include the BMS within… the short training course they provide, and that is of course a big endorsement for us that we appreciate. But beyond that, right now Ignacio [Romagosa], the Director of IAMZ, is working towards developing one project with different partners at the European level, where IBP also will be taking part.” This will use both the training material that IBP has developed in the course of these three years, and also the BMS. Says Ndeye Ndack: “the programme that he’s thinking of will be targeting breeders, in which case we believe BMS will be a good tool for them.”

Watch IAMZ’ interview with Ndeye Ndack below (or on YouTube) for more, including GCP’s approach to capacity building, how the GCP-IAMZ relationship began, and the stellar support that IAMZ has provided.

So even as we come to the finish line of this first IB–MYC marathon with the final training session, many more races are yet to be run and many new pathways are opening up for Johnson’s “new varieties of breeders” – and perhaps a new variety of trainers too. We at GCP would like to take this opportunity to give our special thanks to our friends at IAMZ–CIHEAM, and to thank and congratulate all IB–MYC participants and trainers for their commitment, hard work and fantastic achievements.

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.

Jean-François Rami

“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:

To evaluate the stay-green drought-resistance mechanism in plant architecture and genetic backgrounds appropriate to Mali.
To develop sorghum germplasm populations enriched for stay-green genes that also carry genes for adaptation to cropping environments in Mali.
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!

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”

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.
