Victor Kommerell was the program manager of the CGIAR Research Programs on Maize (MAIZE; 2017-2021) and Wheat (WHEAT; 2012-2021). He previously worked as a consultant to the CGIAR on strategy, human resources and project management, which included facilitation of a 2020 sustainability plan for the 10 CGIAR gene banks and an external evaluation of ILAC.
Prior to working with the CGIAR, Victor worked with the Chief Prosecutor at the International Criminal Court and led a change management program at NATO HQ, after having worked for Perot Systems (people change management) and the Leipzig Trade Fair (b-to-b marketing).
After a 37-year career, Hans-Joachim Braun is retiring from the International Maize and Wheat Improvement Center (CIMMYT). As the director of the Global Wheat Program and the CGIAR Research Program on Wheat, Braun’s legacy will resonate throughout halls, greenhouses and fields of wheat research worldwide.
We caught up with him to capture some of his career milestones, best travel stories, and vision for the future of CIMMYT and global wheat production. And, of course, his retirement plans in the German countryside.

Major career milestones
Native to Germany, Braun moved to Mexico in 1981 to complete his PhD research at CIMMYT’s experimental station in Obrégon, in the state of Sonora. His research focused on identifying the optimum location to breed spring wheat for developing countries — and he found that Obrégon was in fact the ideal location.
His first posting with CIMMYT was in Turkey in 1985, as a breeder in the International Winter Wheat Improvement Program (IWWIP). This was the first CGIAR breeding program hosted by a CIMMYT co-operator, that later developed into the joint Turkey, CIMMYT and the International Center for Agricultural Research in the Dry Areas (ICARDA) winter wheat program. “In 1990, when the Commonwealth of Independent States was established, I saw this tremendous opportunity to work with Central Asia to develop better wheat varieties,” he said. “Today, IWWIP varieties are grown on nearly 3 million hectares.”
Although Braun was determined to become a wheat breeder, he never actually intended to spend his entire career with one institution. “Eventually I worked my entire career for CIMMYT. Not so usual anymore, but it was very rewarding. CIMMYT is at my heart; it is what I know.”

“Make the link to the unexpected”
One of Braun’s standout memories was a major discovery when he first came to Turkey. When evaluating elite lines from outside the country — in particular lines from a similar environment in the Great Plains — his team noticed they were failing but nobody knew why.
Two of his colleagues had just returned from Australia, where research had recently identified micronutrient disorders in soil as a major constraint for cereal production. The team tried applying micro-nutrients to wheat plots, and it became crystal clear that zinc deficiency was the underlying cause. “Once aware that micro-nutrient disorders can cause severe growth problems, it was a minor step to identify boron toxicity as another issue. Looking back, it was so obvious. The cover picture of a FAO book on global soil analysis showed a rice field with zinc deficiency, and Turkey produces more boron than the rest of the world combined.”
“We tested the soil and found zinc deficiency was widespread, not just in the soils, but also in humans.” This led to a long-term cooperation with plant nutrition scientists from Cukurova University, now Sabanci University, in Istanbul.
But zinc deficiency did not explain all growth problems. Soil-borne diseases — cyst and lesion nematodes, and root and crown rot — were also widespread. In 1999, CIMMYT initiated a soil-borne disease screening program with Turkish colleagues that continues until today. Over the coming decade, CIMMYT’s wheat program will make zinc a core trait and all lines will have at least 25% more zinc in the grain than currently grown varieties.
After 21 years in Turkey, Braun accepted the position as director of CIMMYT’s Global Wheat Program and moved back to Mexico.

Partnerships and friendships
Braun emphasized the importance of “mutual trust and connections,” especially with cooperators in the national agricultural research systems of partner countries. This strong global network contributed to another major milestone in CIMMYT wheat research: the rapid development and release of varieties with strong resistance to the virulent Ug99 race of wheat rust. This network, led by Cornell University, prevented a potential global wheat rust epidemic.
CIMMYT’s relationship with Mexico’s Ministry of Agriculture and the Obregón farmers union, the Patronato, is especially important to Braun.
In 1955, Patronato farmers made 200 hectares of land available, free if charge, to Norman Borlaug. The first farm community in the developing world to support research, it became CIMMYT’s principal wheat breeding experimental station: Norman Borlaug Experimental Station, or CENEB. When Borlaug visited Obregón for the last time in 2009, the Patronato farmers had a big surprise.
“I was just getting out of the shower in my room in Obregón when I got a call from Jorge Artee Elias Calles, the president of the Patronato,” Braun recalls. “He said, ‘Hans, I’m really happy to inform you that Patronato decided to donate $1 million.’”
The donation, in honor of Borlaug’s lifetime of collaboration and global impact, was given for CIMMYT’s research on wheat diseases.
“This relationship and support from the Obregón farmers is really tremendous,” Braun says. “Obregón is a really special place to me. I am admittedly a little bit biased, because Obregón gave me a PhD.”

A worldwide perspective
Braun’s decades of international research and travel has yielded just as many stories and adventures as it has high-impact wheat varieties.
He remembers seeing areas marked with red tape as he surveyed wheat fields in Afghanistan in the 1990s, and the shock and fear he felt when he was informed that they were uncleared landmine areas. “I was never more scared than in that moment, and I followed the footsteps of the guy in front of me exactly,” Braun recalls.
On a different trip to Afghanistan, Braun met a farmer who had struggled with a yellow rust epidemic and was now growing CIMMYT lines that were resistant to it.
“The difference between his field and his neighbors’ was so incredible. When he learned I had developed the variety he was so thankful. He wanted to invite me to his home for dinner. Interestingly, he called it Mexican wheat, as all modern varieties are called there, though it came from the winter wheat program in Turkey.”
Seeing the impact of CIMMYT’s work on farmers was always a highlight for Braun.

CIMMYT’s future
Braun considers wheat research to be still in a “blessed environment” because a culture of openly-shared germplasm, knowledge and information among the global wheat community is still the norm. “I only can hope this is maintained, because it is the basis for future wheat improvement.”
His pride in his program and colleagues is clear.
“A successful, full-fledged wheat breeding program must have breeders, quantitative genetics, pathology, physiology, molecular science, wide crossing, quality, nutrition, bioinformatics, statistics, agronomy and input from economists and gender experts,” in addition to a broad target area, he remarked at an acceptance address for the Norman Borlaug Lifetime Achievement award.
“How many programs worldwide have this expertise and meet the target criteria? The Global Wheat Program is unique — no other wheat breeding program has a comparable impact. Today, around 60 million hectares are sown with CIMMYT-derived wheat varieties, increasing the annual income of farmers by around $3 billion dollars. Not bad for an annual investment in breeding of around $25 million dollars. And I don’t take credit for CIMMYT only, this is achieved through the excellent collaboration we have with national programs.”
A bright future for wheat, and for Braun

After retirement, Braun is looking forward to settling in rural Inzlingen, Germany, and being surrounded by the beautiful countryside and mountains, alongside his wife Johanna. They look forward to skiing, running, e-biking and other leisure activities.
“One other thing I will try — though most people will not believe me because I’m famous for not cooking — but I am really looking into experimenting with flour and baking,” he says.
Despite his relaxing retirement plans, Braun hopes to continue to support wheat research, whether it is through CIMMYT or through long friendships with national partners, raising awareness of population growth, the “problem of all problems” in his view.
“We have today 300 million more hungry people than in 1985. The road to zero hunger in 2030 is long and will need substantial efforts. In 1970, Organization for Economic Co-Operation and Development (OECD) countries agreed to spend 0.7% of GDP on official development assistance. Today only 6 countries meet this target and the average of all OECD countries has never been higher than 0.4%. Something needs to change to end extreme poverty — and that on top of COVID-19. The demand for wheat is increasing, and at the same time the area under wheat cultivation needs to be reduced, a double challenge. We need a strong maize and wheat program. The world needs a strong CIMMYT.”

The International Maize and Wheat Improvement Center (CIMMYT) from Mexico and the German Julius Kühn Institute (JKI) signed a Declaration of Intent to intensify joint research on disease-resistant and stress-tolerant wheat. Representatives of both institutions met in Berlin at the International Conference on Improving Drought Stress Tolerance of Crops.
Climate Resilient Maize for Asia is supported by Germany’s development agency GIZ, and implemented as a public-private partnership, which targets enhanced resilience among resource-poor, maize-based farming families in South and Southeast Asia by providing them with abiotic stress-tolerant maize hybrids adapted to rain-fed stress-prone production systems for crop diversification, intensification and higher yields.
Most of the maize in Asia is grown as a rain-fed crop, which is prone to vagaries of seasonal monsoon rains. This is clearly reflected in the productivity of maize under rain-fed systems — usually less than half of the irrigated system. The erratic distribution pattern of monsoon rains results in drought or water logging at different crop growth stages, which is the main factor responsible for relatively low productivity of rain-fed maize. Due to the possibility of uncertain economic returns, farmers often hesitate to invest in improved seed, fertilizers and inputs, which further add to poor yields of rain-fed maize. Climate change effects are further threatening an already challenging maize mega-environment in the Asian tropics, which are identified as subject to climate change effects, with high vulnerability and low adoption capacity.
The project deals with high priorities of Asian stakeholders related to improving maize production in the face of current and anticipated effects of climate change and access to diverse and valuable maize germplasm, building upon the GIZ-funded project known as “Abiotic stress tolerant maize for increasing income and food security among the poor in South and Southeast Asia,” where significant progress is being made towards understanding the rain-fed stress-prone agro-ecologies in South and Southeast Asia, development of improved maize germplasm with enhanced levels of tolerance to drought, waterlogging or combined stress tolerance.
OBJECTIVES
Using data on elevation, aridity index and mean annual rainfall, a climate similarity map with a total 30 zones was developed for South Asia. This is useful in planning regional hybrid trials respective environment analogue.
New hybrid combinations by crossing promising stress-tolerant lines and evaluated across moisture regimes, including managed drought and waterlogging stresses, and optimal conditions, and a set of 50 promising hybrids are ready for large-scale adaptive trials.
Among the inbred lines developed under the project, four most promising lines were globally released CML (CIMMYT Maize Lines), namely CML-562, CML-563, CML-564 and CML-565, for use in low-land tropical breeding programs targeting stress-prone rainfed environment.
Total 18 Quantitative Trait Locus (QTLs) for grain yield under waterlogging and 21 QTLs for grain yield and anthesis-siling interval under drought were identified using genome-wide association studies and analyses of bi-parental populations. These validated genomic regions are candidate for introgression into elite Asia-adapted genetic background.
Breeder ready marker assays (KASP assays) have been developed for the 18 significant genomic regions that typically explained more than 10 percent of phenotypic variance under water-logging stress.
Protocol for rapid-cycle genomic selection (RC-GS) optimized with regards to constitution of suitable target population, and suitable statistical model for genomic selection.
Genetically enhanced cycle (C2) of two multi-parent synthetic populations were developed by inter-mating top 5 percent progenies with high genotypically estimated breeding values (GEBVs) were submitted for subjecting to double haploid for deriving new generation of stress-resilient maize lines

On March 4, 2019, staff from the International Maize and Wheat Improvement Center (CIMMYT) welcomed Gerd Müller, Germany’s Federal Minister of Economic Cooperation and Development (BMZ), for a short visit to CIMMYT’s global headquarters in Mexico. Before exploring the campus and sitting down to hear about CIMMYT’s latest innovations in maize and wheat research, Minister Müller challenged the scientists gathered there by asking: “Is a world with no hunger actually possible?”
“It is possible, but it will require a lot of research and development activities to get there,” replied CIMMYT’s director general, Martin Kropff.
With $3.5 billion generated in benefits annually, CIMMYT is well positioned for Minister Müller’s challenge. CIMMYT works throughout the developing world to improve livelihoods and foster more productive, sustainable maize and wheat farming. Its portfolio squarely targets critical challenges, including food insecurity and malnutrition, climate change and environmental degradation. In addition, over 50 percent of maize and wheat grown in the developing world is based on CIMMYT varieties.

Germany has generously supported CIMMYT’s work for decades in a quest to answer this very question, which aligns with the German government’s agenda to improving food and nutrition security, the environment and livelihoods.
“CIMMYT is working to find ways to allow developing countries to grow maize and wheat on less land so that a larger percentage of it can be freed for nutritious and higher value cash crops. This requires better seeds that are adapted to biotic and abiotic stressors, smarter agronomy and machinery, which CIMMYT develops with partners,” Kropff explained.
CIMMYT works between smallholders and small companies to create an incentive on one side to grow varieties and on the other side, to increase demand for quality grain that will ultimately become the tortillas and bread on customers’ dinner tables. These sustainable sourcing and breeding efforts depend on the breathtaking diversity of maize and wheat housed at CIMMYT’s genebank, the Wellhausen-Anderson Plant Genetic Resources Center, which is supported by German funding along with solar panels that generate clean energy for the genebank.
Through funding for the CGIAR Research Program on WHEAT and the CIM Integrated Experts Program, Germany’s GIZ and BMZ have also supported CIMMYT research into gender and innovation processes in Africa, Central and South Asia, enhancing gender awareness in both projects and rural communities and mainstreaming gender-sensitive approaches in agricultural research. As a result, CIMMYT researchers and partners have increased gender equality in wheat-based cropping systems in Ethiopia, reduced the burden of women’s wheat cleaning work in Afghanistan, and hosted a series of training courses promoting the integration of gender awareness and analysis in research for development.

In addition, the CIM Integrated Experts program has allowed CIMMYT to increase its efforts to scale up agricultural innovations and link research to specific development needs. With support from GIZ and in collaboration with the PPPLab, in 2018 CIMMYT researchers developed a trial version of the Scaling Scan, a tool which helps researchers to design and manage scaling at all project phases: at the beginning, during and after implementation.
CIMMYT is committed to improving livelihoods and helping farmers stay competitive through increasing labor productivity and reducing costs. CIMMYT’s mechanization team works to identify, develop, test and improve technologies that reduce drudgery and enable smallholders in Mexico, sub-Saharan Africa and South Asia to adopt sustainable intensification practices, which require greater farm power and precision. In Ethiopia, CIMMYT has an ongoing collaboration with the GIZ/BMZ green innovation center — established as part of the ONE WORLD – No Hunger initiative — and is working with GIZ in Namibia to provide knowledge, expertise and capacity building on conservation agriculture. This includes the organization of training courses to mechanics and service providers on everything from the use to the repair of machinery and small-scale mechanization services.
“We’re on a mission to improve livelihoods through transforming smallholder agriculture, much of which depends on empowering women, scaling, market development and pushing for policies that would create the right incentives. Partnerships with local and international stakeholders such as Germany are at the core of CIMMYT’s operations and allow for us to have global impact,” said Kropff.
“Could we turn it on?” asks Germany’s federal minister of economic cooperation and development, Gerd Müller, during a small-scale machinery demonstration to show off the latest achievements of MasAgro, an innovative sustainable intensification project that works with more than 500,000 maize and wheat farmers in Mexico.

Agricultural attachés from 10 Mexican embassies visited the headquarters of the International Maize and Wheat Improvement Center (CIMMYT) on February 15. Countries represented included, Australia, Belgium, France, Germany, Hungary, Israel, Kazakhstan, Spain, the Netherlands and New Zealand.
Annie Tremblay, who was representing the Netherlands, gave a presentation on agriculture in the Netherlands. She emphasized the most commonly traded commodities between the Netherlands and Mexico and said she sees Mexico as a “sleeping giant” in the flower-trading world.
Following Tremblay’s presentation, Martin Kropff talked about how CIMMYT works globally to improve livelihoods. As Kropff explained CIMMYT’s biofortification work, he stressed that in a perfect world people would be able to diversify their diets and get nutrients from all kinds of plants, but that many people CIMMYT serves are living on less than two dollars a day. “This is not the solution, but it is a solution.”
Bram Govaerts gave a presentation about the work Sustainable Intensification Program in Latin America (SIP-LatAm) is doing and discussed the importance of public-private partnerships to the MasAgro program. This underscored Kropff’s points about the importance of public-private partnerships to CIMMYT and the importance of corporate social responsibility.
The final presentation to the group of attachés was by Hans Braun and Carolina Saint Pierre on the Global Wheat Program. They emphasized wheat as a good source of fiber, antioxidants, micronutrients and protein. The presentation focused on global partnerships in the wheat program and meeting future production goals.
The attachés then toured the CIMMYT campus, learning about the germplasm bank and biodiversity, the global wheat and maize breeding programs and goals to improve seeds and crops. They also were introduced to CIMMYT’s work enhancing nutrition, food safety and processing quality in the seed health labs and about sustainable intensification to improve rural livelihoods.
To conclude, attachés discussed the current priorities of their embassies and potential collaborations between their embassies in Mexico and CIMMYT.
WHEN FERTILIZER IS LIMITED, BREEDING SOLUTIONS FOR THE STAFF OF LIFE IN AFRICA
A farmer applying a solution only very few can afford in adequate amounts: nitrogen fertilisers for poor soils in Africa
Among the major crops produced and consumed in sub-Saharan Africa (SSA), maize leads, consumed by more than 650 million Africans. Therefore, maize and Africa’s food security and socioeconomic stability are inseparably intertwined. Poor maize productivity has contributed to food shortages, high prices and has pushed more Africans to extreme poverty. Low-fertility soils are part of the problem, and maize varieties specially bred for poor soils offer a partial solution.
Maize and Soil—Chemical Solution, Socioeconomic Problem, Nitrogen in Sips Not Gulps
After water, poor soil nitrogen is the single most critical constraint for Africa’s maize production. Lack of, or inadequate, soil nitrogen leads to low yields and crop failure. Farmers therefore need nitrogen fertilizers to improve yields when soils are depleted or infertile. However, for most smallholder farmers, the harsh reality is that chemical fertilizers—or adequate amounts of them—remain out of their reach, unaffordable owing to the high costs.
To address this, the International Maize and Wheat Improvement Center (CIMMYT) and its partners are working through the Improved Maize for African Soils (IMAS) Project to develop maize varieties that are more efficient at using the small quantities of fertilizer that smallholder farmers can afford, typically less than 30 kilograms per hectare. This means that farmers obtain up to 50 percent more from the limited fertilizer applied.
From problems to solutions: everybody wins!
IMAS focuses on improving the genetics of maize varieties to better match the typical soil profiles of smallholder maize farms in eastern and southern Africa. Different maize varieties respond very differently to soil nitrogen stress. ‘In complement to improved agronomy and soil management, selection of appropriate maize varieties for specific soil conditions can play an enormous role in improving productivity and food security in Africa,’ observes Biswanath Das, a maize breeder at CIMMYT. By packaging nitrogen-use efficiency in the seed, IMAS hopes to improve maize yields efficiently and economically for small holder farmers in Africa.
At this year’s Global Soil Week (GSW) running from April 19–23 in Berlin, Germany, it is important that tangible solutions be formulated for farmers to nurture and sustain healthier soils. Engagement and dialogue forums like GSW and the recent #TalkSoil tweet chat initiated by the International Center for Tropical Agriculture and Shamba Shape Up (a Kenyan television show targeting smallholder farmers) are critical for inclusive discussions to help farmers in Africa.
TEXCOCO, MEXICO, April 19, 2015 – Sustainable Development Goals being addressed at the Global Soil Week cannot ignore dependence on maize as a staple food for millions in Africa, and the need to help smallholder farmers maximize yields in African soils.
Today, Berlin, Germany, hosts soil scientists from across the world who have converged for the Global Soil Week (GSW) to find solutions for sustainable land governance and soil management. Farmers and other stakeholders in agriculture are keen to see outcomes that will translate into healthier soils for sustainable development in Africa and elsewhere.
For Africa’s smallholder farmers, low-fertility soils with poor nitrogen-supplying capacity are only second to drought as a limiting factor. Consequently, farmers suffer low yields and crop failure, a situation that has crippled food security for more than half (60 percent) of the population in this region who depend on smallscale farm produce.
To improve productivity, farmers apply nitrogen fertilizers, which provide necessary nutrients the soil needs to feed plants. However, most farmers cannot afford to apply the required amount of fertilizers because the costs are too high for them. It is estimated that nitrogen fertilizer costs as much as six times more in Africa that in any other part of the world. “For my one-acre farm, I use a 50-kilogram bag that costs KES 4,000 [USD 42]. This is a lot of money, so I have to use very little to save for the next planting season,” says Ms. Lucy Wawera, a farmer in Embu County, Kenya.
Maize is the most important cereal crop in sub-Saharan Africa consumed by more than 650 million people. This dependence therefore dictates that solutions to Africa’s fragile food security also focus on improving maize production. The International Maize and Wheat Improvement Center (CIMMYT) and its partners are working through the Improved Maize for African Soils (IMAS) Project to address -nitrogen depleted soils. They are exploiting naturally occurring genetic variation in maize to develop new varieties that are nitrogen-use-efficient or better at utilizing the limited amounts of fertilizer that smallholders can afford in sub-Saharan Africa—typically less than 30 kilograms. These new varieties yield up to 50 percent more than current commercial varieties in nitrogen-poor soils. IMAS draws on strong collaboration between the public and private sectors involving the Kenya Agricultural and Livestock Research Organization, South Africa’s Agricultural Research Council and DuPont Pioneer.
“Matching appropriate crop varieties to specific soil systems and ecologies can play a major role in improving productivity of fragile smallholder farming systems in Africa,” says Dr. Biswanath Das, a maize breeder at CIMMYT. “Increasing productivity on existing farmland will prevent encroachment into marginal or virgin lands which leads to further soil degradation.” Helping farmers deal with the challenge of low-fertility soils will remain a key focus for international and national actors in Africa throughout 2015, the UN International Year of Soils. Open discussion platforms should therefore be encouraged to facilitate comprehensive and inclusive dialogue on soil matters. A recent tweet-chat forum titled ‘#TalkSoil’ initiated by the International Center for Tropical Agriculture and Shamba Shape Up (a Kenyan television program on smallholder agriculture) brought together scientists, farmers, regulators and other actors to discuss a single topic – soil.
It is therefore important that GSW deliberations formulate sustainable solutions for farmers to build healthier soils, and to nurture and maintain them. This will not only arrest soil deterioration but also protect a critical livelihood for billions, and a source and ‘sustainer’ of life for us all – agriculture, deeply rooted and inseparable from soil.
Frankfurt, Germany – December 9, 2014 – Wild ancestral relatives of wheat will play a key role in fortifying the world’s food supply as climate change warms the planet, according to a team of top scientists.
Heat and drought are already a major cause of wheat yield losses in both developing and developed countries, a situation that scientists predict will worsen due to warmer temperatures and erratic rainfall patterns caused by global climate change. Some of the potential risks were demonstrated in 2003, when farmers in France lost nearly a quarter of their crop due to an unusually hot growing season.
More than 100 plant scientists from 22 major wheat-growing countries in the global south and north, met last week to discuss an ambitious international plan to incorporate the most advanced genetic technologies into traditional plant breeding to improve heat and drought tolerance of wheat.
“Not only are the livelihoods of farmers at risk from climate change, but people living in some of the world’s most vulnerable areas could see entire food supplies wiped out with increasing frequency if we don’t act quickly to boost the resilience of wheat to heat waves and more extreme periods of drought,” said Matthew Reynolds, a distinguished scientist at the International Maize and Wheat Improvement Center (CIMMYT), who co-organized the three-day Heat and Drought Wheat Improvement Consortium (HeDWIC) meeting.
“A new generation of plant screening and molecular technologies can speed up our capacity to transfer stress-tolerance traits into new wheat varieties. Wild relatives of wheat, which evolved in hot and dry places, will provide the crucial genes we need for crop improvement,” Reynolds added.
Findings in a report released earlier this year by the Intergovernmental Panel on Climate Change (IPCC) state it is very likely that heat waves will occur more often and last longer throughout the 21st century and rainfall will be more unpredictable.
Mean surface temperatures could potentially rise by between 2 to 5 degrees Celsius or more, despite efforts to limit the global rise in temperature to 2 degrees Celsius, the report said.
Wheat – a major staple crop, which provides 20 percent of calories consumed worldwide and is an important source of protein especially for poor consumers– is expected to be subject to dramatic increases in temperature and more variable and extreme precipitation, particularly in tropical and semi-tropical regions.
“The risks to food security will be highest for people living in vulnerable parts of Africa and Asia, but will affect the disadvantaged and low-income communities in every country,” Reynolds said.
Adaptation can play a key role in reducing potential socio-economic shocks caused by climate change.
HeDWIC, launched in 2014 by the Global Agricultural Research Partnership (CGIAR) Research Program on Wheat, is a multi-disciplinary, 15- to 20-year global partnership serving as a vehicle for plant scientists to address these food security challenges. In its initial stages, it will be funded by the CGIAR Research Program on Wheat, and attract support from other public and private sector donors.
The meeting was organized by CIMMYT, CGIAR’s lead research center for wheat, part of a global coalition that includes CGIAR’s International Centre for Agricultural Research in the Dry Areas (ICARDA), and shares a mandate to deliver new wheat cultivars to resource-poor farmers. It was co-sponsored by Bayer CropScience, which has heavily invested in wheat breeding as part of its overall mission to provide agricultural technologies for professional farmers and growers.
Co-organizers of the event included the Julius Kuehn Institute (JKI), Germany’s Federal Research Centre for Cultivated Plants affiliated with the country’s Federal Ministry of Food and Agriculture, and the international public-private Wheat Initiative coalition.
“The meeting was a good example of the private and public sectors working together to solve a common problem,” said Hans Braun, director of CIMMYT’s Global Wheat Program.
“We’ve laid the foundations for a successful research venture that will help farmers and many of the world’s most marginalized people living in some of the most difficult environmental conditions. From here, we’ll produce a comprehensive road map,” he said.
Representatives from international development and science funding agencies also attended the three-day meeting

CIMMYT’s Global Maize Program will establish and operate a maize doubled haploid (DH) facility in Kiboko, Kenya. With financial support from the Bill & Melinda Gates Foundation, this centralized DH facility will be able to produce at least 100,000 DH lines per year by 2016, thus strengthening maize breeding programs in Africa and improving breeding efficiency. The DH technology will reduce the cost and time for breeding work as it enables rapid development of homozygous maize lines and fast-tracking development and release of elite maize varieties. The facility will be built at the Kiboko Experimental Station on 20 hectares of land provided by the Kenya Agricultural Research Institute (KARI). The Maize DHAfrica Project will both establish the facility and refine the DH technology in collaboration with the University of Hohenheim, Germany.
“One of the important ways to increase genetic gains and accelerate the development and deployment of improved varieties is to reduce the time needed for inbred development,” said B.M. Prasanna, CIMMYT’s Global Maize Program director. “The technology would also allow breeders to couple molecular marker-based selection for important traits such as disease resistance and quality at an early generation.” A project planning and review meeting held in Nairobi during 18-19 February 2013 was attended by representatives from national agriculture research systems, Kenya Seed Company, Seed Trade Association of Kenya, University of Hohenheim, the International Institute of Tropical Agriculture (IITA), and CIMMYT. “This technology will help us significantly improve maize food security in sub-Saharan Africa,” said Joseph Ochieng, KARI deputy director (food crops and crop protection), who spoke on behalf of the institute’s director Ephraim Mukisira. The KARI official emphasized the importance of educating stakeholders on this novel technology to ensure they understand its benefits and use the DH lines efficiently in breeding programs.
The DH facility will also serve as a training hub for scientists and technical personnel from national programs and small and medium-sized seed companies that may not have advanced breeding facilities. It will enhance CIMMYT’s capacity to generate DH lines for effective use in Africa-based breeding programs such as the Drought Tolerant Maize in Africa (DTMA), Water Efficient Maize for Africa (WEMA), Improved Maize for African Soils (IMAS), and the Maize HarvestPlus in Africa.
“We are fully enthused and geared towards establishing a state-of-the-art DH Facility in Kiboko,” said Sotero Bumagat, CIMMYT maize DH operations manager and project leader. During a visit to the field site in Kiboko, Bumagat explained the proposed layout of the facility and received very positive feedback. Seed sector stakeholders who participated in the meeting expressed excitement and anticipation to see the DH facility established and operational in 2013. “This is a technology that the seed sector in Africa has been waiting for,” said Willy Bett, managing director of the Kenya Seed Company and member of the Project Steering Committee. “Faster breeding of improved maize varieties is quite important for effectively managing problems such as the maize lethal necrosis disease,” said Evans Sikinyi, executive officer of the Seed Trade Association of Kenya.
CIMMYT has received a new flow cytometer that will allow speedy DNA analysis for breeding. “With this new technology, we save tremendous amounts of money, time, and resources. We’re really grateful to Partec for this donation and to the German people for their support,” senior scientist George Mahuku thanked Edmund Duckwitz, German Ambassador to Mexico, and Hubertus von Römer, Science Attaché of the German Embassy, during their visit to CIMMYT on 18 December 2012. The German delegation officially handed over a new flow cytometer donated by Partec, a German biotechnology company, thus re-establishing a partnership that began in 1999 when Partec equipped a CIMMYT laboratory with a flow cytometer.
According to Mahuku, the new device will facilitate producing good hybrids to fight drought, heat, or diseases, such as the maize lethal necrosis disease in Eastern Africa. “We have identified some sources of resistance to this virus,” says Mahuku, “but we need to cross the sources into the appropriate background.” Finding the sources of resistance used to be a costly and lengthy process. “Before, we would plant two hectares, and after two or three weeks, we would find out that half of them weren’t desirable, so you’d have to chop them out. This wastes part of the investment in land preparation, the chemicals for treating, and the people planting all those things,” explained Mahuku. “With this equipment, we germinate the seeds and are able to analyze them within three days. Thus we plant only the desirable materials and save a month and a half of work.” CIMMYT director general Thomas Lumpkin added: “This instrument allows us to look at the blueprint of the plant, instead of waiting for the plant to grow.” The cytometer will ultimately benefit both maize and wheat research at CIMMYT.
The delegation had the opportunity to observe a demonstration of a quick DNA analysis using the Partec cytometer.
The use of doubled haploids in maize breeding was first proposed more than half a century ago. Today, the in vivo haploid induction technique is routinely used in maize inbred line development, in both the public and the private sector. The DH technology enhances maize breeding in two ways: 1) it reduces the time required to produce completely homozygous inbred lines. Whereas six or more generations of self-pollination are needed to traditionally produce inbreds, DH technology produces inbreds in only two generations; and 2) because the higher genetic variance among DH lines compared to F2 plants, or selfed F3 or F4 families, improves the effectiveness of selection.
DH technology in maize breeding was the theme of a training workshop organized by the University of Hohenheim (UH) and CIMMYT at Stuttgart, Germany, during 11-15 June 2012. The program was organized under the ‘Abiotic stress tolerant maize for Asia’ (ATMA) project funded by Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ). A total of 21 scientists, including maize breeders and physiologists from Bangladesh, India, Philippines, Vietnam, UH, and CIMMYT attended the weeklong course. Experts on DH technology from UH, CIMMYT, and German seed companies served as resource persons on the course, delivering lectures on various aspects of DH technology in maize breeding. Mornings were devoted to lectures whilst in the afternoons, participants undertook hands-on, practical project in various aspects of DH line development and production.
Day-1 presenters included UH’s Wolfgang Schipprack; Vanessa Prigge, an ex-PhD student of UH and CIMMYT who is currently working as a Potato Breeder in SaKa Pflanzenzucht GbR, and T. Wegenast, Dow AgroSciences. In the afternoon, participants worked on identification of haploid kernels from various DH-induced populations and planted haploid kernels on germination paper for development of seedlings. DH lab members at UH explained and demonstrated the selection of haploid kernels and developing seedlings for colchicine treatment for chromosome doubling.
On the second day, B. Schilling and B. Devezi of the UH-DH lab jointly presented various aspects of management of greenhouses, safety issues, and requirements for running a successful DH program. E. Senger a PhD student at UH, and Vijay Chaikam, CIMMYT, also shared their experiences. During the afternoon, preparation of colchicine solution, preparation of maize seedling for colchicine treatment, application of colchicine treatment, and the transplanting the seedlings in greenhouse were demonstrated to the participants.
Participants also visited the UH-DH research station at Eckartsweier, where Schipprack detailed various field based aspects of DH development including selection of plants for transplanting in field, organized demonstration of mechanized transplanting of D0 plants, management of D0 nursery, and identification of false positives in the nursery. After the D0 nursery, participants visited the DH inducer development and maintenance nursery, D2 nurseries, and the isolation block for production of induction crosses. On the final day of the workshop, UH’s A.E. Melchinger delivered a lecture on the application of marker-based prediction strategies for DH lines and discussed various models and approaches for prediction of DH lines. George Mahuku shared updates on DH line production and development of tropical inducer lines at CIMMYT, and talked about possible models for use of DH technology by national breeding programs in Asia. Participants appreciated the initiatives and efforts of CIMMYT and UH, and discussed various options to get DH technology into their breeding programs.
Avinash Singode, Directorate of Maize Research, Bhagya Rani Banik, Bangladesh Agriculture Research Institute, and Le Quy Kha, National Maize Research Institute, were very supportive of the course and expressed their sincere thanks to organizers. P.H. Zaidi, Project Coordinator, ATMA, thanks Prof. Melchinger and Schipprack and his team for their time, efforts, and inputs in jointly organizing the workshop, and emphasized the need to follow up on this in the hope that within one year, each participating institution will have access to DH technology in their program, at least through Model-1 (send their most elite population to CIMMYT, and get back DH lines), as suggested by Mahuku.
The ‘Abiotic stress tolerant maize for Asia’ (ATMA) project aims to increase incomes and food security for the poor of South and southeast Asia, with the assistance of Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ). The second phase was launched in May 2011, and on 11 June 2012, the first annual progress review and planning session took place at the University of Hohenheim (UH), Stuttgart, Germany.
All the collaborating institutions were represented, including: the Directorate of Maize Research (DMR), Maharana Pratap University of Agricultural Science & Technology, India, Acharya NG Ranga Agriculture University, India, the National Maize Research Institute (NMRI), Vietnam, Bangladesh Agricultural Research Institute, the Institute of Plant Breeding, Philippines, UH, Germany, and CIMMYT.
The meeting began with a warm welcome from Albrecht E. Melchinger (UH), who highlighted the partnerships between UH and various institutions of the CGIAR, but in particular the partnership between UH and CIMMYT, which has existed for more than 20 years. In the opening session, Raman Babu, maize molecular breeder, CIMMYT, discussed recent advances in genomic selection and the genome-wide association mapping approach, focusing on its potential use in maize breeding, particularly for complex traits such as drought and water-logging.
The ATMA project country leaders, including Melchinger, R. Sai Kumar (DMR), Le Quy Kha (NMRI), and Bhagya Rani Banik, then presented the project’s progress over the past year. During this time, socio-economic studies were carried out, and these were jointly presented by T.R. Prabhakarna (CIMMYT-Delhi) and V.K. Yadav (DMR). After summarizing CIMMYT-Asia’s overall progress, CIMMYT’s senior maize physiologist and ATMA project coordinator, P.H. Zaidi, went on to outline areas that need special attention over the coming year in order to meet the project’s
milestones and commitments.
Led by MT Vinayan, post-doctoral fellow at CIMMYT-Hyderabad, the afternoon session focused on creating a detailed work-plan, assigning tasks among partners, and discussing activities for the next year. Zaidi mentioned that to date, all the multi-location trials have been conducted in India due to issues in exporting of trials to partners in other countries. However, since the export permit is now available, the ATMA trials will now be shipped to partners from Bangladesh, Philippines, and Vietnam for evaluation at their sites.
Delegates at the meeting also discussed how the ATMA project will provide opportunities for further research and learning. Among these, ATMA partners will have the opportunity to attend a capacity building workshop on “Double Haploid in Maize Breeding” to be held at UH. Details of the research project that ATMA Ph.D. scholar Do Van Dung (NMRI) will be conducting were also discussed and finalized, while two interns, one each from Bangladesh and Vietnam, have been invited to work at CIMMYT-Hyderabad. Their six-week placements will provide them with hands-on experience on key aspects of breeding for enhancing water-logging and drought tolerance in maize.
The long-standing and fruitful relationship between Germany and CIMMYT received a boost on 01 May 2011 when, as part of an official tour of Latin America, the President of the Republic of Germany, Christian Wulff, visited CIMMYT headquarters to learn more of the center’s work and discuss strengthened partnerships. President Wulff was accompanied by his wife, Bettina, and nearly 60 distinguished guests including German vice ministers and members of parliament, embassy personnel, and business and media representatives. Greeting the guests were CIMMYT Director General Tom Lumpkin and several of the center’s German and German-speaking staff.
After touring the main exhibition hall showcasing Dr. Norman Borlaug’s achievements and contributions to agricultural development, including his Nobel Prize of 1970 and the Aztec Eagle of the same year from Mexico, the entourage attended a presentation by Hans-Joachim Braun, Director of CIMMYT’s Global Wheat Program. The talk addressed food security and related constraints—climate change, the rising demand for grains, the increasing scarcity of resources like land, water, and fertilizer—as well as CIMMYT’s work in the developing world and its relationship with Germany, a long-term and significant supporter of the center. To name just a few examples, German contributions have funded work on stress tolerant maize for Africa, a regional wheat network for Central Asia, and wheat pathology research for South Asia. German staff at CIMMYT and our partnerships with German universities and institutes have been of enormous¡ value in getting improved technology to farmers.
The whirlwind tour then moved to the seed bank, with exhibitions of maize and wheat genetic resources outside and a visit inside to the upper seed storage chamber. In an impromptu closing statement, President Wulff thanked CIMMYT and described his positive impression of the visit and Braun’s presentation, which he called one of the clearest and most fact-based he had ever heard. Reports on the visit in the German media have referred to CIMMYT as a “highly-regarded research center.In addition to Lumpkin and Braun, CIMMYT staff interacting with the guests included Marianne Bänziger, deputy director general, research and partnerships; Scott Ferguson, deputy director general, corporate services; Peter Wenzl, head of the crops research informatics lab; Susanne Dreisigacker, molecular biologist and head of marker applications in wheat; GIS expert Kai Sonder; agricultural economist Tina Beuchelt; Marc Rojas, coordinator of the International Strategy for Maize Improvement; and Petr Kosina, assisting with the event management.
