Today, we travel the Milky Way on a voyage to Mozambique. Our man along the Milky Way is Rogério Marcos Chiulele (pictured), a lecturer at Mozambique’s Universidade Eduardo Mondlane’s Crop Science Department. He is also the lead scientist for cowpea research in Mozambique for the Tropical Legumes I (TLI) project. This gives Rogério a crucial tri-focal down-to-earth and away-from-the-clouds perspective on cowpea pedagogy, research and development. It is through this pragmatic triple-lens prism that Rogerio speaks to us today, once he’s captained us safely back from the stars to Planet Earth, Southeast Africa. After the protein and profit, next stop for him and team is ridding cowpeas of pod-sucking pests, among other things slated for the future. But back from the future to the present and its rooted realities…Problems, yes, but also lots of good scores, plus a deft sleight of hand that are bound to have you starry-eyed, we bet.

…cowpeas rank fourth as the most cultivated crop…”

Q: Tell us about Mozambique and cowpeas: are they important?

The devastating effects of nematodes on cowpea roots.

The devastating effects of nematodes on cowpea roots.

In Mozambique, cowpeas are an important source of food, for both protein and profit, particularly for the resource-poor households that benefit from cowpea income and nutrition. In terms of cultivation, cowpeas rank fourth as the most cultivated crop after maize, cassava and groundnuts, accounting for about 9 percent of the total cultivated area, and estimated at nearly four million hectares of smallholder farms. The crop is produced for grain and leaves, mostly for household consumption but it is becoming increasingly important as a supplement for household income.

But while its potential for food, protein and income is recognised, the realisation of such potential is still limited by drought due to irregular and insufficient rain; affliction by pests such as aphids, flower thrips and nematodes; diseases such as cowpea aphid mosaic virus and cowpea golden mosaic virus; and cultivation of low-yielding and non-improved varieties.

…we backcross to varieties with traits that farmers prefer…”

Q: And on cowpea research and breeding?
Since 2008, Universidade Eduardo Mondlane [UEM] established a cowpea-breeding programme for addressing some of the limiting constraints affecting cowpea production and productivity. This has been possible through collaboration with different funding institutions such as the Generation Challenge Programme.

2008: Screening of the 300 genotypes.

That same year [2008], a UEM research team that I coordinate qualified for a GCP capacity-building à la carte grant. In this project, we screened 300 Mozambican cowpea lines for drought tolerance. From these, we identified 84 genotypes that were either high-yielding or drought-tolerant. We further evaluated the 84 genotypes for another three seasons in two locations. From the 84, we identified six genotypes that not only had the two sought-after traits, but were also adapted to different environments.

In 2010, the UEM team joined the TLI project. For the six pre-identified genotypes, the UEM breeding programme is using marker-assisted recurrent selection [MARS] and marker-assisted backcrossing [MABC], combining drought tolerance and resistance to major biotic stresses occurring in Mozambique. In MABC, we are conducting a backcross to varieties with traits that farmers prefer, which includes aspects such as large seeds, early maturity and high leaf production.

…we conducted a farmers’ participatory varietal selection to glean farmers’ perceptions and preferences on cowpea varieties and traits…”

Q: What is the main focus in your work, and how and when do farmers come in?
The breeding work conducted by UEM is targeting all Mozambican agroecologies, but with particular focus on southern Mozambique which is drought-prone. In addition to drought, the area is plagued by many pests such as aphids, flower thrips, nematodes and pod-sucking pests. So, in addition to drought tolerance, we are conducting screening and selection for resistance to aphids, flower thrips and nematodes. In the near future, we will start screening for resistance to pod-sucking pests.

2009: field screening of the 84 genotypes in diff locations.

In 2009, we conducted a farmers’ participatory varietal selection to glean farmers’ perceptions and preferences on cowpea varieties and traits. From the study, six of the lines passed participatory variety selection with farmers, as they were large-seeded with good leaf production which provides additional food.

we hope to release three varieties in 2015…Our involvement with GCP has not only increased our exposure, but also brought along tangible benefits… I firmly believe black-eyed peas can really make a difference.”

Q: To what would you attribute the successes your team is scoring, and what are your goals for the future, besides screening for pod-sucking pests?
The success of the work that the Eduardo Mondlane team is doing is partly due to the collaboration and partnership with USA’s University of California, Riverside [UCR]. UCR sent us 60 lines from the GCP cowpea reference set* [Editorial note: see explanation at the bottom], which we evaluated for drought tolerance for four seasons in two locations – one with average rainfall and the other drought-prone. As these lines were already drought-tolerant, we tested them for adaptation to the local environment, and for high yield. From the set, we hope to release three varieties in 2015. In addition, for evaluating the different varieties, we also crossed the local varieties with black-eyed peas, which have a huge market appeal: local varieties fetch roughly half a US dollar per kilo, compared to black-eyed peas whose price is in the region of four to five US dollars.

2013: multilocation trials.

2013: multilocation trials.

Our involvement with GCP has not only increased our exposure, but also brought along tangible benefits. For example, previously, nothing was being done on drought tolerance for cowpeas. But now we receive and exchange material, for example, the black-eyed peas from UCR that we received through GCP, which are set to boost production and markets, thereby improving lives and livelihoods. Amongst the varieties we are proposing to release is one black-eye type. I firmly believe black-eyed peas can really make a difference.

In addition, besides funding a PhD for one of our researchers, Arsenio Ndeve, who is currently at UCR, the Generation Challenge Programme, contributed to improvement on storage and irrigation facilities. We purchased five deep freezers for seed storage and one irrigation pump. Presently, we have adequate storage facilities and we conduct trials even during the off-season, thanks to the irrigation pump provided by GCP.

****

And on that upbeat note even as the challenge ahead is immense, today’s chat with Rogério ends here. To both pod-sucking pests and all manner of plagues on cowpeas, beware, as thy days are numbered: it would seem that Rogério and team firmly say: “A pox on both your houses!”

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.

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.

Cowpeas – uncowed and unbowed: believing that what could be can be, in breeding

 Africa, Cowpeas, Legumes  No Responses »

Phil Roberts

Phil Roberts

Like its legume relatives, cowpeas belong to a cluster of crops that are still referred to in some spheres of the crop-breeding world as ‘orphan crops’. This, because they have largely been bypassed by the unprecedented advances that have propelled ‘bigger’ crops into the world of molecular breeding, endowed as they are with the genomic resources necessary. But as we shall hear from Phil Roberts (pictured), of the University of California–Riverside, USA, and also the cowpea research leader for the Tropical Legumes I Project (TLI), despite the prefix in the  name, this ‘little kid’ in the ‘breeding block’ called cowpeas is uncowed and unbowed, confidently striding into the world of modern crop breeding, right alongside the ‘big boys’! What more on this new kid on the block of modern molecular breeding? Phil’s at hand to fill us in…

Vigna the VIP that shrinks with the violets
But is no shrinking violet, by any means, as we shall see. Also known  as niébé in francophone Africa, and in USA as black-eyed peas (no relation to the musical group, however, hence no capitals!), this drought-tolerant ancient crop (Vigna unguiculata [L] Walp) originated in West Africa. It is highly efficient in fixing nitrogen in the unforgiving and dry sandy soils of the drier tropics. And that is not all. This modest VIP is not addicted to the limelight and is in fact outright lowly and ultra-social: like their fetching African counterpart in the flower family, the African violet, cowpeas will contentedly thrive under the canopy of others, blooming in the shade and growing alongside various cereal and root crops, without going suicidal for lack of limelight and being in the crowd. With such an easy-going personality, added to their adaptability, cowpeas have sprinted ahead to become the most important grain legume in sub-Saharan Africa for both subsistence and cash. But – as always – there are two sides to every story, and sadly, not all about cowpeas is stellar…

Improved varieties are urgently needed to narrow the gap between actual and potential yields… modern breeding techniques… can play a vital role”

A cowpea experimental plot at IITA.

What could be, and what molecular breeding has to do with it
Yields are low, only reaching a mere 10 to 30 percent of their potential, primarily because of insect- and disease-attack, sometimes further compounded by chronic drought in the desiccated drylands cowpeas generally call home. “Improved varieties are urgently needed to narrow the gap between actual and potential yields,” says Phil. The cowpea project he leads in TLI is implemented through GCP’s Legume Research Initiative. Phil adds, “Such varieties are particularly valuable on small farms, where costly agricultural inputs are not an option. Modern breeding techniques, resulting from the genomics revolution, can play a vital role in improving cowpea materials.”

He and his research team are therefore developing genomic resources that country-based breeding programmes can use. Target-country partners are Institut de l’Environnement et de Recherches Agricoles (INERA) in Burkina Faso; Universidade Eduardo Mondlane in Mozambique; and Institut Sénégalais de Recherches Agricoles (ISRA) in Senegal. Other partners are the International Institute of Tropical Agriculture (IITA) headquartered in Nigeria and USA’s Feed the Future Innovation Labs for Collaborative Research on Grain Legumes and for Climate Resilient Cowpeas.

It’s a lot easier and quicker, and certainly less hit-or-miss than traditional methods!… By eliminating some phenotyping steps and identifying plants carrying positive-trait alleles for use in crossing, they will also shorten the time needed to breed better-adapted cowpea varieties preferred by farmers and markets.”

On target, and multiplying the score
[First, a rapid lesson on plant-genetics jargon so we can continue our story uninterrupted: ‘QTLs’ stands for quantitative trait loci, a technical term in quantitative genetics to describe the locations where genetic variation is associated with variation in a quantitative trait. QTL analysis estimates how many genes control a particular trait. ‘Allele’ means an alternative form of a the same gene. Continuing with the story…]

The curved shape means that these cowpea pods are mature and ready for harvesting.

Culinary curves and curls: the curved shape means that these cowpea pods are mature and ripe for harvesting.

“We first verified 30 cowpea lines as sources of drought tolerance and pest resistance,” Phil recalls. “Using molecular markers, we can identify the genomic regions of the QTLs that are responsible for the desired target phenotype, and stack those QTLs to improve germplasm resistance to drought or pests. It’s a lot easier and quicker, and certainly less hit-or-miss than traditional methods! However, standing alone, QTLs are not the silver bullet in plant breeding. What happens is that QTL information complements visual selection. Moreover, QTL discovery must be based on accurate phenotyping information, which is the starting point, providing pointers on where to look within the cowpea genome. Molecular breeding can improve varieties for several traits in tandem,” suggests Phil. “Hence, farmers can expect a more rapid delivery of cowpea varieties that are not only higher-yielding, but also resistant to several stresses at once.”

And what are Phil and team doing to contribute to making this happen?

“The genomic resources from Phase I – especially genotyping platforms and QTL knowledge – are being used in Phase II of the TLI Project to establish breeding paradigms, using molecular breeding approaches,” Phil reveals. He adds that these approaches include marker-assisted recurrent selection (MARS) and marker assisted back-crossing (MABC). “These paradigms were tested in the cowpea target countries in Africa,” Phil continues. “By eliminating some phenotyping steps and identifying plants carrying positive-trait alleles for use in crossing, they will also shorten the time needed to breed better-adapted cowpea varieties preferred by farmers and markets.”

… best-yielding lines will be released as improved varieties… others will be used…as elite parents…”

Future work
What of the future? Phil fills us in: “The advanced breeding lines developed in TLI Phase II are now entering multi-location performance testing in the target African countries. It is expected that best-yielding lines will be released as improved varieties, while others will be used in the breeding programmes as elite parents for generating new breeding lines for cowpeas.”

Clearly then, the job is not yet done, as the ultimate goal is to deliver better cowpeas to farmers. But while this goal is yet to be attained and – realistically – can only be some more years down the road, it is also equally clear that Phil and his team have already chalked up remarkable achievements in the quest to improve cowpeas. They hope to continue pressing onwards and upwards in the proposed Tropical Legumes III Project, the anticipated successor to TLI and its twin project TLII – Tropical Legumes II.

A grounding in the reality of groundnut research in Africa, and why blood is thicker than water

 Africa, Genetics, Genomics, Groundnuts, Legumes  2 Responses »

Vincent Vadez

Vincent Vadez

Today, we travel to yet another sun-kissed spot, leaving California behind but keeping it legumes. We land in Africa for some ground truths on groundnuts with Vincent Vadez (pictured), groundnut research leader for the Tropical Legumes I (TLI) Project. Vincent fills us in on facts and figures on groundnuts and Africa – a tale of ups and downs, triumphs and trials, but also of  ‘family’ alliances not feuds, and of problems, yes,  but also their present or potential solutions. On to the story then! Read on to find out why groundnuts are…

….A very mixed bag in Africa
Groundnuts (Arachis hypogaea L), also called peanuts, are a significant subsistence and food crop in sub-Saharan Africa. There, groundnuts are grown in practically every country, with the continent accounting for roughly a quarter of the world’s production. Despite this rosy African statistic, problems abound: for example, nearly half (40 percent) of the of the world’s total acreage for groundnuts is in Africa, which dramatically dims the 25 percent global production quota.

In Africa, groundnuts are typically cultivated in moderate rainfall areas across the continent, usually by women.

In Africa, groundnuts are typically cultivated in moderate rainfall areas across the continent, usually by women. (See editorial note* at the end of the story)

Clearly then, Africa’s yields are low, borne out by telling statistics which show African production at 950 kilos per hectare, in acute contrast to 1.8 tonnes per hectare in Asia.

…every year, yields worth about USD 500 million are lost”

What ails Africa’s production?
The main constraints hampering higher yields and quality in Africa are intermittent drought due to erratic rainfall, as well as terminal drought during maturation. And that is not all, because foliar (leaf) diseases such as the late leaf spot (LLS) or groundnut rosette are also taking their toll.  Economically speaking, every year, yields worth about USD 500 million are lost to drought, diseases and pests. Plus, the seeding rates for predominantly bushy groundnut types are low, and therefore insufficient to achieve optimal ground cover. Thus, genetic limitations meet and mingle with major agronomic shortcomings in the cultivation of groundnuts, making it…

…. A tough nut to crack
Groundnuts are mostly cultivated by impoverished farmers living in the semi-arid tropics where rainfall is both low and erratic.

Tough it may be for crop scientists, but clearly not too tough for these two youngsters shelling groundnuts at Mhperembe Market, Malawi.

“To help double the productivity of this crop over the next 10 years, we need to improve groundnuts’ ability to resist drought and diseases without farmers needing to purchase costly agricultural inputs,” says Vincent.

But the crop’s genetic structure is complex, plus, for resistance to these stresses, its genetic diversity is narrow. “Groundnuts are therefore difficult and slow to breed using conventional methods,” says Vincent. And yet, as we shall see later, groundnuts are distinctly disadvantaged when it comes to molecular breeding. But first, the good news!

…wild relatives have genes for resisting the stresses… molecular markers can play a critical role”

Why blood is thicker than water, and family black sheep are valued
Kith and kin are key in groundnut science. Vincent points out that groundnuts have several wild relatives that carry the necessary genes for resisting the stresses – especially leaf diseases – to which the crop is susceptible. These genes can be transferred from the wild cousins to the cultivated crop by blending conventional and molecular breeding techniques. But that is easier said than done, because cultivated groundnuts can’t cross naturally with their wild relatives owing to chromosomic differences.

“In modern breeding, molecular markers can play a critical role,” says Vincent. “Using markers, one can know the locations of genes of interest from an agronomic perspective, and we can then transfer these genes from the wild relatives into the groundnut varieties preferred by farmers and their markets.”

[The] ‘variegated’ partnership has been essential for unlocking wild groundnut diversity…”

Partnerships in and out of Africa, core capacities
“Partners are key to this work,” says Vincent. The groundnut work is led by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), with collaborators in the target countries, which are Malawi (Chitedze Agricultural Research Centre), Senegal (Institut sénégalais de recherches agricoles ‒ ISRA) and Tanzania (Agricultural Research Institute, Naliendele), Moving forward together, continuous capacity building for partners in Africa is part and parcel of the project. To this end, there have been several training workshops in core areas such as molecular breeding and phenotyping, farmer field days in the context of participatory varietal selection, as well as longer-term training on more complex topics such as drought, in addition to equipping the partners with the critical infrastructure needed for effective phenotyping.

Freshly dug-up groundnuts.

Further afield out of Africa, Vincent’s team also collaborates with the Brazilian Agricultural Research Corporation (EMBRAPA), France’s Centre de coopération internationale en recherche agronomique pour le développement ‒ CIRAD, and USA’s University of Georgia.

This ‘variegated’ partnership has been essential for unlocking the wild groundnut diversity when about 12 years ago the EMBRAPA team successfully generated a number of ‘synthetic’ groundnuts from their wild relatives. Unlike the wild groundnuts, these synthetic groundnuts can be crossed to the cultivated type, bringing with them treasure troves of beneficial genes pertaining to the wild that would be otherwise unreachable for the cultivated varieties. Taking this one step further, the CIRAD‒ISRA team, in a close North‒South partnership, has used one of the synthetics from the Brazilian programme to generate new genetic diversity in the groundnut cultivar Fleur11. They are using additional synthetics from ICRISAT to further enlarge this genetic diversity in cultivated groundnuts.

These techniques and tools provide signposts on the genome of varieties for characteristics of importance”

A world first for an ‘orphan’, goals achieved, and what next
Among other goals, the team notably achieved a world first: “To produce the first SSR-based genetic linkage map for cultivated groundnuts!” declares Vincent. SSR stands for simple sequence repeat. The map was published in 2009,  followed later on by a groundnut consensus map in 2012.

But what do these maps and their publication mean for groundnut production? Vincent explains: “These techniques and tools provide signposts on the genome of varieties for characteristics of importance ‒ for instance, resistance to a disease ‒ and these are used in combination to speed up the development of groundnut varieties that are more resistant to the stresses found in the harsh environments where most of the tropical world’s poor farmers live. Accelerating development means quicker delivery to farmers who are at high risk of going hungry. TLI Phase I produced synthetic groundnuts with new genes for disease resistance.”

In Phase II of the TLI Project which terminates in mid-2014, the team has continued to identify new genetic and genomic resources, for instance new sources of drought resistance from the germplasm and which are currently being used in the development of new breeding stocks. What is significant about this is that groundnuts ‒ like most other members of the legume family ‒ do not have much in the way of genomic and molecular-genetic resources, and are in fact consequently referred to in some circles as ‘orphans’ of the genome revolution. The focus has also been on resistance to rust, early and late leaf spot, and rosette – all economically critical diseases – by tapping the resilience of GBPD4, a cultivar resistant to rust and leaf spot, and introducing its dual resistance to fortify the most popular varieties against these diseases. The team also hopes to scale up these promising examples.

We believe this team is firmly on the way to fulfilling their two-fold project objectives which were: (1) to develop genomic resources and produce the first molecular-breeding products of the crop by injecting  disease resistance (from TLI Phase I work) into farmer- and market-preferred varieties; and, (2)  to lay the foundation for future marker-assisted recurrent selection (MARS) breeding by tapping on newly identified sources of drought tolerance.

 the genetic stocks that hold the most promise to overcome leaf disease are found in the wild relatives… A thorough reflection is needed to combine good genetics with sound agronomic management”

The future
But the team is not resting on their laurels, as the work will not stop with the fulfillment of project objectives. In many ways, their achievements are in fact just the beginning. The new breeding stocks developed during TLI Phase II need to be evaluated further for their drought tolerance and disease resistance prior to their deployment in breeding programmes, and this activity ‒ among others ‒ is included for the next phase of the work in the proposed Tropical Legumes III project. In particular, the genetic stocks that hold the most promise to overcome leaf disease are found in the wild relatives. Thus, the existing materials need to be fully exploited and more need to be produced to cover the full breadth of potential stresses. Vincent adds “Of course an increasing part of the efforts will be about assuring quality evaluation data, meaning we must continue to significantly enhance the capacity ‒ both human and physical ‒ of our partners in target countries. Last but not least, the good wheat and rice cultivars that directly arose from the green revolution would have been nothing without nitrogen fertiliser and irrigation.” Vincent adds that the same applies to groundnuts: they are cultivated in infertile soil, at seeding rates that are unlikely to optimise productivity.

For this reason, and others explained above, “A thorough reflection is needed to combine good genetics with sound agronomic management,” Vincent concludes, stressing the importance of what he terms as ‘looking beyond  the fence’. Vincent’s parting shot, as our conversation draws to close: “In fact, I have grown increasingly convinced over the past year that we probably overlook those agronomic aspects in our genetic improvements at our peril, and we clearly need a re-think of how to better combine genetic improvement with the  most suitable and farmer-acceptable agronomic management of the crop.”

Much food for thought there! And probably the beginnings of an animated conversation to which a groundnut crop model, on which Vincent and team are currently working, could soon yield some interesting answers on the most suitable genetic-by-management packages, and therefore guide the most adequate targets for crop improvement.

Women in science

“Women can do advanced agricultural science, and do it well!” Elizabeth Parkes, cassava researcher, Ghana

Being a woman scientist in today’s world (or at any time in history!) is no mean feat, science traditionally having been the domain of men. We are therefore drawn to this sub-theme: Inspiring change, in addition to the global theme Equality for women is progress for all, To mark International Women’s Day tomorrow, UNESCO has developed an interactive tool which collates facts and figures from across the world on women in science. The cold scientific truth displayed in the attractive petri dish design shows that only 30 percent of researchers worldwide are women.

At GCP, we have been fortunate enough to have a cross-generational spectrum of, not only women scientists, but that even rarer species, women science leaders – who head a project or suite of projects and activities, and who actively nurture and mentor future science leaders – to ultimately contribute to the fulfilment of our mission: Using genetic diversity and advanced plant science to improve crops for greater food security in the developing world. The United Nations has designated 2014 as the Year of Family Farming. GCP’s women researchers have contributed to improving the lives of their farming counterparts the world over, especially in the developing world where on average, 43 percent of the agricultural labour force are women, rising to 60 percent and 70 percent in some regions. (FAO)

Please mind the gap…to leap to that all-important initiation into science

The UNESCO tool mentioned above and embedded to the left allows users to “explore and visualise gender gaps in the pipeline leading to a research career, from the decision to get a doctorate degree to the fields of science that women pursue and the sectors in which they work” with this affirmation: “Perhaps most importantly, the data tool shows just how important it is to encourage girls to pursue mathematics and science at a young age.”

In our International Women’s Day multimedia expo, we profile the life and work of a selection of our smart scientific sisters through words, pictures and sound, to explain just how they overcame obstacles, from taking that first hurdle to study science at an early age, to mobility up the research rungs to reach the very top of their game, all the while balancing work, life and family.

After a virtual world-tour of research institutes early on in her career, Masdiar took the knowledge of molecular breeding back home, to the Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development (ICABIOGRAD), where she personally took up the challenge to work with the fledgling world of biotechnology, set up a lab, and helped establish molecular breeding in her country. In an amazing 37-years-odd research career, Masdiar tended not only tender rice shoots, but also budding blossoms in the form of her many students, whom she nurtured and mentored throughout their studies, and who have now seamlessly inherited her mantle to carry on the mission with the same ever-bright spirit.

We now skip continents and oceans  to meet the feisty, continent- and crop-hopping scientist, Rebecca Nelson (Cornell University, USA). “I wanted to get out into the world and try and have a practical impact instead of doing research for the sake of research,” Rebecca says – and that she did, first leaving her native USA to work in the International Rice Research Institute (IRRI) in the Philippines. There she teamed up with friend and colleague, Masdiar Bustamam, to establish Masdiar’s laboratory at ICABIOGRAD, Indonesia. The American continent then called her back, where she moved countries and institutes, and switched from rice to maize research, marking the launch of her GCP experience – which simultaneously introduced her to her a whole new network of international crop researchers. This rich research tapestry was  woven together by a poignant pain deep in her heart, as a mother herself, of “so many mothers not being able to feed their families.” Rebecca wanted to combat this problem,  and crop science is her weapon.

Zeba Seraj

Zeba Seraj

Next, we meet another true mother of molecular plant breeding, Zeba Seraj (University of Dhaka, Bangladesh). Zeba, whose mind is perpetually on call in the pursuit of science, has been around the world, and from plants to animals and back again in the course of her multifaceted science career. During her PhD and postdoc experience in the UK, still with fauna, she cultivated her expertise in molecular biology and recombinant DNA technology, but a lack of opportunities in that field back in Bangladesh saw her enter the world of crop science, where she has remained ever since. Back at her alma mater, the University of Dhaka, she founded a molecular biology lab, and has nurtured and inspired generations of young biochemists. Her GCP project, using molecular markers to develop salt-tolerant rice, was a real eye-opener for her, and allowed her to truly ‘see’ how applied science and such a practical project would have a direct impact on her country’s food security, now and in the future.

Sigrid Heuer

Sigrid Heuer

Our next scientist is also truly motivated by putting theory into practice through the application of upstream research all the way down the river, and directly into farmers’ fields. Sigrid Heuer (now with the Australian Centre for Plant Functional Genomics), a German national, has pursued her scientific ventures in Europe, Africa, Asia, and now Oceania, with many challenges along the way. Enter the Generation Challenge Programme, and the chance for Sigrid (then at IRRI)  to lead a major project, the Pup1 rice phosphorus uptake project, which taught Sigrid the A–Z of project management, and gave her ample scope for professional growth. Her team made a major scientific breakthrough, which was not only documented in international journals, but was also widely covered by global media.  From this pinnacle, Sigrid  passed on the baton to other scientists and moved on to new conquests.

Arllet Portugal

Arllet Portugal

Now, all this research we’ve been celebrating generates a massive amount of data, as you can well imagine. What exactly can our scientists do with all that data, and how can they organise them? GCP’s Arllet Portugal, hailing from The Philippines, gives us the lowdown on smart and SHARP data management whilst also giving us some insights into how she started out on the long and winding road to leading data management for GCP’s Integrated Breeding Platform. In particular, Arllet describes the considerable challenge of changing researchers’ mindsets regarding the importance of effective data management in the context of their research, and enthuses over the excitement with which developing-country researchers welcome the GCP-funded electronic tablets they now use to collect and record data directly in the field.

Armin Bhuiya

Armin Bhuiya

If there were a muse for young women scientists, it might very well be the subject of our next blogpost profile, Armin Bhuiya (Bangladesh Rice Research Institute). After completing her master’s degree on hybrid rice in her native Bangladesh, Armin was already thinking like a true change-catalyst scientist, trying to discover what line of research would be the most useful for her country and the world. After much deliberation, she embarked on a PhD focusing on developing salt- and submergence-tolerant rice. This wise choice would take her to study under the expert eye of Abdelbagi Ismail at IRRI, in The Philippines, with the helping hand of a GCP–DuPont postgraduate fellowship. There, she learnt much in the way of precise and meticulous research, while also taking advantage to self-train in modern molecular plant breeding methods. Our bright resourceful student has now advanced to the patient erudite teacher – as she takes home her knowledge of high-tech research methods to share with her colleagues and students in Bangladesh.

Elizabeth Parkes

Elizabeth Parkes

Hello Africa! Switching continents and media, we now we move from the written medium to tune in to the melodic tones of Elizabeth Parkes (Crops Research Institute [CRI] of Ghana’s Council for Scientific and Industrial Research [CSIR], currently on leave of absence at the International Institute of Tropical Agriculture [ IITA]). We’re now at profile number seven in GCP’s gallery of women in science. Elizabeth, who is GCP’s Lead Cassava Researcher in Ghana, narrates an all-inclusive engaging story on the importance to agriculture of women scientists, women farmers, and cassava the wonder crop – all captured on memorable sound waves in this podcast.

If the gravity of words inscribed holds more weight, you can also read in depth about Elizabeth in a blogpost on this outstanding sister of science. Witness the full radiance of Elizabeth’s work in the life-changing world in which she operates; as she characteristically says, “I’ve pushed to make people recognise that women can do advanced agricultural science, and do it well.” And she is no exception to her own rule, as she grew professionally, apparently keeping pace with some of the giant cassava she has helped to develop through the years. But it is her role as nurturer, mentor and teacher that really raises her head-and-shoulders above the rest, from setting up a pioneering biotech lab at CRI–CSIR to conscientiously mentoring her many students and charges in work as in life, because, for Elizabeth, capacity building and cassava are inextricably coupled!

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.

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!

Cassava on the catwalk: Ghanaian ‘make-over’ for crop-science underdog

‘Made (up) in Ghana’

In the world of crop research as in the fashion industry, there are super-models, mere models, spectators and rank outsiders. Make no bones about it, trusty old cassava (Manihot esculenta) is a crop of very modest beginnings, but now finally strutting the research catwalk alongside the biggest and the best.

Elizabeth Parkes

Elizabeth Parkes

An ancient crop thought to have been first domesticated in Latin America more than 10,000 years ago, it was exported by Portuguese slave traders from Brazil to Africa in the 16th century as a cheap source of carbohydrates. From there, today we travel half a millennium forward in time – and in space, on to Ghana – to catch up with the latest on cassava in the 21st century.

Come on a guided tour with Elizabeth Parkes (pictured), of Ghana’s Crops Research Institute (CRI, of the Council for Scientific and Industrial Research, CSIR), currently on leave of absence at the International Institute of Tropical Agriculture (IITA).

A hard-knock life, but still going strong
In keeping with its humble heritage, cassava is a crop which has long been reputed for being more than a little worn through at the elbows, commonly known as a “poor man’s crop” according to GCP cassava breeder and researcher, Elizabeth Parkes. However, much like a dishevelled duffle coat, what the crop lacks in shimmer and shine, it makes up for in sturdiness and dependability, rising to the occasion time and again by filling a critical gap – that of putting food in bellies – with a readiness and ease that its more sophisticated crop relatives have often struggled to keep up with. Elizabeth explains:  “It has kept people alive over the years.” By the same token, the crop – now one of Africa’s most important staples – is fondly known in Ghana as bankye, meaning a ‘gift from the government’, thanks to its reliability and capacity to meet needs that other crops cannot. There is even a popular song in the country which pays homage to the crop as an indefatigable evergreen, conquering even the most willful and wily of weeds!

However, as cassava experts such as Elizabeth know only too well, behind this well-intentioned lyrical window dressing is the poignant story of a crop badly in need of a pressing pick-me-up. Hardy as it may seem on the surface, cassava is riddled with myriad problems of a political, physiological, environmental and socioeconomic nature, further compounded by the interactions between these. For starters, while it may be a timeless classic and a must-have item at the family table for a good part of Africa, à la mode it is not, or at least not for short-sighted policy-makers looking first and foremost to tighten their purse strings in straitened times, or for quick-fix, rapid-impact,  silver-bullet solutions: “African governments don’t invest many resources in research. Money is so meager, and funds have mostly come from external agencies looking to develop major cereals such as rice. Cassava has been ignored and has suffered a handicap as a result – it’s more or less an orphan crop now,” Elizabeth laments. Besides having to bear witness to their favourite outfit being left on the funding shelf, cassava breeders such as Elizabeth are also faced with a hotchpotch of hurdles in the field: “In addition to factors such as pests and disease, cassava is a long-season and very labour-intensive crop. It can take a whole year before you can expect to reap any rewards, and if you don’t have a strong team who can step in at different points throughout the breeding  process, you can often find unexpected results at the end of it, and then you have to start all over again,” Elizabeth reveals. Robust as it may be, then, cassava is no easy customer in the field: “After making crosses, you don’t have many seeds to move you to the next level, simply because with cassava, you just don’t get the numbers: some are not compatible, some are not flowering; it’s a real bottleneck that needs to be overcome,” she affirms.

No time for skirting the issue
And at the ready to flex their research muscles and rise to these considerable challenges was Elizabeth and her Ghanaian CRI  team, who – with GCP support and in unison with colleagues from across Africa and the wider GCP cassava community – have been working flat out to put cassava firmly back on the research runway.

Thanks to funders such as GCP, who recognised that we couldn’t afford to turn a blind eye to the plight of this struggling crop, cassava has been given a voice…cassava is no longer just a poor man’s staple”

Elizabeth walks us through the team’s game plan: “GCP socioeconomist Glenn Hyman and team undertook a study to identify the best area in Ghana for supporting cassava flowering [Editor’s note: Glenn works at the International Center for Tropical Agriculture, CIAT]. Armed with that information, we have been applying grafting techniques, using hormones to induce flowering in Ghana and beyond.” The initiative is starting to bear fruit: “At the IITA–Nigeria Ubiaja site, for example, flowering is underway at factory-like efficiency – it’s a great asset. The soil has also greatly improved – we haven’t been able to pinpoint the exact cause yet, but what we’ve seen is that all cultivars there will now flower,” she reveals. Elizabeth’s team has been making steady progress in biotechnological techniques such as DNA extraction: thanks to work led by then GCP cassava comrade Martin Fregene (then with the International Center for Tropical Agriculture, CIAT, and now with the Donald Danforth Plant Science Center) and colleagues, focusing on the development of more reliable and robust simple sequence repeat (SSR) markers, Elizabeth was able to carry out genetic diversity diagnosis work on cassava, collecting germplasm from all over Ghana for the global GCP cassava reference set. [Editor’s note: 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]

Similar work was also conducted in Nigeria and Guatemala. So has this tremendous and tenacious teamwork proved strong enough to drag cassava out of the doldrums? Elizabeth certainly seems to think so: “Thanks to funders such as GCP, who recognised that we couldn’t afford to turn a blind eye to the plight of this struggling crop, cassava has been given a voice. Having worked together to understand the peculiarities of this crop, cassava is no longer just a poor man’s staple: beyond subsistence, it is becoming a crop of high starch quality, and of real use for industry, confectionary and even biofuels,” she enthuses.

Thankfully, it’s a most welcome change of tide that shows no sign of abating any time soon.  Human capacity, Elizabeth says, is going from strength to strength, with three GCP-funded Ghanaian postgraduate students advancing well, two of them working on PhDs in what would normally be considered, according to Elizabeth, a ‘no-go area’ of cassava research – that is, cassava drought tolerance and post-harvest physiological deterioration (PPD), as well as bio-fortification. Efforts by the CRI team have resulted in the release of some 14–15 new drought-tolerant and PPD-resistant varieties in Ghana to date; all are anticipated to have a long shelf-life, and other varieties are also in the pipeline. Biofortified seeds are in the making, with a view to soon mainstream biofortification in the team’s breeding activities. The biofortification work is in collaboration with a sister CGIAR Challenge Programme, HarvestPlus.

The impact of our GCP-supported research on cassava has been remarkable. Above all, it’s been the community spirit which has moved things forward so effectively; in this respect, I think researchers working on other crops might want to borrow a leaf from the cassava book!”

Molecular masterstrokes, a leaf to lend despite cold shoulder, and a ‘challenge crop’ befitting Challenge Programmes
Forthcoming plans for Elizabeth and her cassava companions in Ghana include a GCP Cassava Challenge Initiative project which will seek to unearth new marker populations and materials which are drought-tolerant and resistant to cassava mosaic virus and cassava bacterial blight. The team has successfully introgressed materials from CIAT into their landraces, and the next step will be to gauge how best the new genes will react to these traits of interest. In terms of people power, the CRI biotechnology laboratory built with GCP support – and now a regionally accredited ‘Centre of Excellence’ – is a hive of activity for local and international scientists alike, and is consequently bolstering cassava research efforts in the wider subregion. “The impact of our GCP-supported research on cassava has been remarkable. Above all, it’s been the community spirit which has moved things forward so effectively; in this respect, I think researchers working on other crops might want to borrow a leaf from the cassava book!” Elizabeth ventures.

Reflecting back on the conspicuous cocktail of constraints which mired the crop in the early days of her research career – challenges which often resulted in a cold shoulder from many of her research peers over the years – Elizabeth recalls affectionately: “At first, people didn’t want to work on cassava since it’s truly a challenge crop: the genetics of cassava are really tricky. Colleagues from around the globe often asked me: ‘Why not go for a smooth crop which is friendly and easy?’” Her commitment, however, has been unfaltering throughout: “I’ve stuck with cassava because that’s my destiny! And now I see SNPs being developed, as well as numerous other resources. Once you clean something up it becomes more attractive, and my thanks go out to all those who’ve remained dedicated and helped us to achieve this.”

Thus, dusted down and  ‘marked-up’ with a molecular make-over well underway, all evidence now suggests that this once old-hat subsistence crop is en route to becoming the next season’s big research hit, with shiny new cassava varieties soon to be released at a field station near you! Go, Ghana, go!

Something old, something new; Plenty borrowed, and just a bit of  blue…

Why did the Integrated Breeding Platform (IBP) come to be, and what’s the latest offer from the five-year-old Platform? The answers are in this tell-all post on the bright and the bleak in IBP – beauty spots, blues, warts and all! Having heard on data management, breeding, and putting IBP tools, tips and services into use, let’s now take a couple of steps back and appraise the big picture: the IBP concept itself, candidly retold by an IBP old hand, in a captivating chronicle capturing the highs and lows, the drama and the humdrum, and befittingly capping our current season of IBP stories. Do read on…

We want to put informatics tools in the hands of breeders, be they in the public or private sector including small- and medium-scale enterprises, because we know they can make a huge difference”

Curtain up on BMS version 2, and back to basics on why IBP
January 2014 was a momentous month for our Integrated Breeding Platform, marking the release of version 2 of the Breeding Management System (BMS). After the flurry and fanfare of this special event, we caught up with Graham McLaren (pictured), GCP’s Bioinformatics and Crop Information Leader, Chair of the IBP Workbench Implementation Team and a member of the IBP Development Team. Graham has been intimately involved in taking IBP from an idea in 2008‒2009 to its initial launch in late 2009.

But what’s the background to all this, and why the need for IBP? Graham fills us in, explaining that in the 1980s and 1990s, informatics was the major contributor to successful plant breeding in large companies like Pioneer and Monsanto. After that, molecular technologies became the main contributors. “But to advance with molecular technologies, you need to have the informatics systems in place,” he says. “One of the biggest constraints to the successful deployment of molecular technologies in public plant breeding, especially in the developing world, is a lack of access to informatics tools to track samples, manage breeding logistics and data, and analyse and support breeding decisions.”

This is why IBP was set up. “We want to put informatics tools in the hands of breeders, be they in the public or private sector including small- and medium-scale enterprises, because we know they can make a huge difference.”

…breeders will not only find… information, but also the tools, services and support to put this information into use, in the context of their local crop-breeding projects…  [the information breeders] have accumulated over the years is mostly held in their heads, in institutional repositories, or in books and published papers. There are few common places for them to share these riches and tap into those of others… IBP  provides one such place.”

The script: common sense, and working wonders
Plant breeders throughout the developing world have a wealth of information on adapting crops to the challenges of their particular environments. They work wonders in their experimental fields to develop crops that help local farmers deal with pests, diseases and less-than-ideal conditions such as drought, floods and poor soils. But this valuable information they have accumulated over the years is mostly held in their heads, in institutional repositories, or in books and published papers. There are few common places for them to share these riches and tap into those of others. The Integrated Breeding Platform (IBP) provides one such place, where breeders will not only find this information, but also the tools, services and support to put this information into use, in the context of their local crop-breeding projects.

Action! Setting the stage for a forward spring, and taking a leap of faith
IBP tackles the information management issues that are at the heart of many breeding processes, goals, pursuits and problems. “Informatics problems are not crop-specific” Graham says. “What GCP is doing is to put in place a generic system for plant breeders to manage and share information. This means they can collaborate and make better decisions about strains of the crops they are breeding and that they use in their programmes. It’s setting the stage for a big leap forward in plant breeding in developing countries.”

The proposal for a crop information system applicable to a wide range of crops attracted the attention of the Bill & Melinda Gates Foundation, which provided core funding for IBP.

According to Graham, the initial five-year USD 12 million grant from the Foundation was “the biggest single investment in an informatics project in CGIAR. It was half of what was needed, and other funders joined in with the other half.” These are the European Commission and the UK’s Department for International Development.

It’s been harder than we imagined… we really needed to employ the strategies used to build aeroplanes! … some of our partners are good at solving research problems but not at developing informatics tools… Our partnership with the software company was pretty unusual…Usually, you draw up the specifications for what you want and the company comes back with the product, like giving a builder an architect’s plans and getting the keys when the building is completed. But it wasn’t like that at all…”

Collaborative construction and conundrum – going off the script, winging it and winning it
Graham describes the hurdles that the team had to overcome along the way. “It’s been harder than we imagined because of the number of partners to coordinate. It’s like building a complicated machine with many parts. The parts built by different people in different places all need to fit when they are put together. It’s so complex, we really needed to employ the strategies used to build aeroplanes!”

It’s been a matter of encouraging all those involved to do what they do best. “I’ve learnt that some of our partners are good at solving research problems but not at developing informatics tools. We were fortunate to find a private company partner to do the software engineering and to have the backing of the Gates Foundation to change our strategy along the way.”

Working with a private-sector company was a first on both sides. “Our partnership with the software company was pretty unusual,” Graham recalls. “Usually, you draw up the specifications for what you want and the company comes back with the product, like giving a builder an architect’s plans and getting the keys when the building is completed. But it wasn’t like that at all. We didn’t know exactly what we wanted in terms of the final system, learning and adapting as we went along. Fortunately, the company was flexible and worked with us step by step. We would describe to them what we wanted, they would go off and work something up, then they would come back and we would dissect it and then they would go away again and rework. This way, they produced the system we wanted. Involving a private company brought us very handsome returns for money: it meant the project could deliver on time, and on budget.”

Breeders in developing countries and small- and medium-sized companies are looking at it… a revenue stream could be secured in a win–win relationship with companies also working to develop agriculture in the developing world”

Act II: going global, and continuous improvement
Now that the alpha version of BMS has been launched, the Bill & Melinda Gates Foundation is encouraging GCP to deploy the Platform more broadly. Graham explains, “Breeders in developing countries and small- and medium-sized companies are looking at it and, of course, they are coming up with ideas of their own. We’ve taken these on board in developing BMS version 2. In anticipation of yet more user feedback on version 2, we anticipate the third version will be released in June 2014.”

He continues: “Deployment will involve training people to use IBP, maintaining the system and developing new tools. We’re talking to the Gates Foundation, and others, about funding for IBP Phase II. While our primary objective is to make the Platform affordable – even free – for public-sector plant breeders in developing countries, we recognise that the system needs to be maintained, supported and upgraded over the years. The question is, will small- and medium-sized plant-breeding enterprises be willing to pay for the system so that some of this maintenance and support can be recovered and the system can become sustainable in the long run? In our GoToMarket Plan, the Marketing Director is canvassing a range of companies asking what services they need and how much they would pay for them. There is a strong need for such a system in this sector and it is clear that a revenue stream could be secured in a win–win relationship with companies also working to develop agriculture in the developing world.”

Graham is convinced that rolling out IBP will have a significant impact on plant breeding in developing countries. “Because IBP has a very wide application, it will speed up crop improvement in many parts of the world and in many different environments. What this means is that new crop varieties will be developed in a more rapid and therefore more efficient manner.”

The Integrated Breeding FieldBook – An African agronomist’s perspective

Feb 242014
 
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…

Yemi Olojede

Yemi Olojede

Yemi Olojede (pictured) is much more than a standard IBP user. 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”

Fastfoward to 2012: Based on feedback, a larger electronic tablet was favoured over the smaller handheld device. Yemi (centre) takes field staff through the paces in tablet use.

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.”

Steaming rice bowl

Steaming rice bowl

What’s the latest from ‘GCP TV’? Plenty! With a world-favourite – rice – featuring high and hot on the menu.

Now serving our latest news, to tease your taste-buds with a tantalising and tingling potpourri of memorable cross-continental rice flavours, all captured on camera for our viewers…

Our brand-new series on YouTube serves up a healthy seven-course video feast inviting our viewers to sink their teeth into rice research at GCP.

First, we settle down for a tête-a-tête in the rice research kitchen with chef extraordinaire, Marie-Noëlle Ndjiondjop, Principal Investigator (PI) of GCP’s Rice Research Initiative in Africa, and Senior Molecular Scientist at Africa Rice Center. Target countries are Burkina Faso, Mali and Nigeria.

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.

Tastes from Asia
To further please your palate with our rice bowl of delights, our next stop is Asia. We are  pleased to offer you the Asian flavour through a peek into the world of molecular rice breeding in the Mekong region. Our connection to this project is through a GCP-funded capacity-building project entitled A Community of Practice for strengthening rice breeding programmes by using genotyping building strategy and improving phenotyping capacity for biotic and abiotic stresses in the Mekong region led by PI Jonaliza Lanceras-Siangliw, of the National Center for Genetic Engineering and Biotechnology (BIOTEC), Thailand (see project poster, and slides on a related drought-tolerance project led by Boonrat Jongdee). BIOTEC’s partners in the Mekong rice breeding CoP are the Cambodian Agricultural Research and Development Institute (CARDI); LAO PDR’s National Agricultural and Forestry Research Institute (NAFRI);  Myanmar’s Department of Agricultural Research (DAR); and Thailand’s Kasetsart University and Ubon Ratchathani University). The video also features former GCP PI, Theerayut Toojinda (BIOTEC) whose project was similarly entitled The ‘Community of Practices’ concept applied to rice production in the Mekong region: Quick conversion of popular rice varieties with emphasis on drought, salinity and grain quality improvement.
