USD 170 million research program to help maize farmers worldwide

cimmyt-maize-farmersBold Initiative Tackles Hunger in Developing World

Washington, July 6, 2011 – The Consultative Group on International Agricultural Research (CGIAR)—the world’s largest international agriculture research coalition—today announced a USD 170 million global alliance and program to expand and accelerate research into maize, the preferred staple food source for more than 900 million people in 94 developing countries, including one third of the world’s malnourished children.

“This program aims to double the productivity of maize farms, while also making those farms more resilient to climate change and reducing the amount of land used for growing the crop,” said Carlos Perez del Castillo, CGIAR Consortium Board Chair.  “As a result, farmers’ incomes are expected to rise and their livelihood opportunities to increase, contributing to rural poverty reduction in developing countries.”

cimmyt-maize-plantingThe CGIAR applies cutting-edge science to foster sustainable agricultural growth that benefits the poor. The new crop varieties, knowledge and other products resulting from the CGIAR’s collaborative research are made widely available, at no cost, to individuals and organizations working for sustainable agricultural development throughout the world.

Under the research program, 40 million smallholder farm family members are expected to see direct benefits by 2020 and 175 million by 2030.  The program is expected to provide enough maize to meet the annual food demands of an additional 135 million consumers by 2020 and 600 million by 2030.

The program will be implemented by the International Maize and Wheat Improvement Center (CIMMYT), and the International Institute of Tropic Agriculture (IITA).

The announcement came as the CGIAR celebrated its 40th anniversary at a ceremony in Washington attended by the President of the World Bank Group, as well as the heads of several of the 15 research centers that make up the CGIAR Consortium of International Agriculture Centers.

Inger Andersen, Vice President of Sustainable Development at the World Bank, and Chair of the CGIAR Fund Council, said the first target group to benefit from the enhanced maize research program would be smallholder farmers who live in environments prone to stress and who have poor access to markets.

“Small holder farmers are among the most vulnerable people in developing countries.” she said. “They should be among the first we seek to help. Enabling these people to produce more and better maize quickly and reliably will help to ensure their well being, as well as that of their communities.”

Studies carried out by CIMMYT show that the demand for maize in the developing world is expected to double between now and 2050.

“This is a highly ambitious project to address world hunger,” said Thomas Lumpkin, Director General of the International Maize and Wheat Improvement Center (CIMMYT). “It will take an enormous amount of work and cooperation between public and private sector institutions to meet the goals. The global challenges facing mankind are immediate and chronic; the time to act is now. Millions of lives depend on our ability to develop sustainable solutions to feed more people with fewer resources than ever before.”

The global alliance that will carry out the research program includes 130 national agricultural research institutes, 18 regional and international organizations, 21 advanced agricultural research institutes, 75 universities worldwide, 46 private sector organizations, 42 non-governmental organizations and farmer associations, and 11 country governments that will host offices dedicated to the program.

The Consultative Group on International Agricultural Research (CGIAR) is a global partnership that unites organizations engaged in research for sustainable development with the funders of this work. The funders include developing and industrialized country governments, foundations, and international and regional organizations. The work they support is carried out by 15 members of the Consortium of International Agricultural Research Centers, in close collaboration with hundreds of partner organizations, including national and regional research institutes, civil society organizations, academia, and the private sector. www.cgiar.orgwww.consortium.cgiar.org

The International Maize and Wheat Improvement Center, known by its Spanish acronym, CIMMYTÂź (staging.cimmyt.org), is a not-for-profit research and training organization with partners in over 100 countries. The center works to sustainably increase the productivity of maize and wheat systems and thus ensure global food security and reduce poverty. The center’s outputs and services include improved maize and wheat varieties and cropping systems, the conservation of maize and wheat genetic resources, and capacity building. CIMMYT belongs to and is funded by the Consultative Group on International Agricultural Research (CGIAR) (www.cgiar.org) and also receives support from national governments, foundations, development banks, and other public and private agencies.

Value from building human capacity

CIMMYT E-News, vol 4 no. 6, June 2007

CIMMYT helps build scientific strength in Turkey.

When you first meet Gul Erginbas and Elif Sahin standing side by side in an experimental wheat plot in Turkey, what stands out are the differences between them. One is dressed very traditionally, head and body covered, the other is in close-fitting denim jeans. It seems these two young postgraduate students could not be less alike. But when it comes to science the external differences disappear. These are two committed and talented young people who hope to make a difference in their own country. They are already making a difference for CIMMYT.

“I really depend on them,” says Julie Nicol, the CIMMYT soil-borne disease pathologist, based in Turkey. “We work in close collaboration with the Turkish Ministry of Agriculture and several universities. Both women have started working on their doctoral degrees, supervised by key university experts and myself. This is a highly effective way to build capacity in applied research both for Turkey and the world.” Having bright and committed students on the ground is also very beneficial to CIMMYT.

The Anadolu Research Institute at Eskisehir is one of Turkey’s oldest and most important agricultural research stations, especially for winter wheat breeding. It is about a three-hour drive east of the capital city, Ankara, on the broad and rolling Anatolian plateau. At this station CIMMYT (together with ICARDA and Turkey) works in winter wheat breeding and also in Nicol’s area of specialization, finding ways to reduce the threat to wheat from pathogens in the soil, the microscopic worms and fungi that cause damage underground long before the impacts are seen in the part of the wheat plant that is above the ground.

Both Sahin and Erginbas have supervisors at their own universities in Turkey but having a CIMMYT scientist like Nicol as a co-advisor really helps. “She brings us a global perspective and makes sure we work with care and precision,” says Elif. “And she really knows the field. It is easy to learn from her,” adds Gul. “With this experience, I hope I can contribute to science in Turkey in the future.”

jun07Erginbas is just beginning work on a project to screen wheat for resistance to a disease called crown rot. It is caused by a microscopic fungus in the soil called Fusarium culmorum (related to but not the same as the Fusarium fungus that causes head blight in wheat) and can cause farmers serious loss of yield. Her first tests have been with plants grown in a greenhouse on the station. Later she will expand her work to the field and as part of her program will spend some time in Australia with the Commonwealth Scientific and Industrial Research Organization (CSIRO). Since there is some evidence that the fungus that causes crown rot can survive for up to two years in crop residues, there is a great interest in this work as more farmers adopt reduced tillage and stubble retention on their land.

Sahin is focusing on an underground pest called the cereal cyst nematode, a tiny worm that can cause great damage to the root system of the plant. It can be responsible for losses of up to 40% of rainfed winter wheat in Turkey and there is evidence that the nematodes are very widespread in west Asia, North Africa, northern India and China. Sahin, funded by a scholarship from the Turkish funding body TUBITAK, is looking for sources of resistance to the pest.

jun06These pathogens are especially damaging when wheat is grown under more marginal conditions, and so the work in Turkey that these two young students are doing may have its greatest impact where farmers struggle the most.

Turning on radios, tuning in to resource-conserving farm practices

CIMMYT E-News, vol 3 no. 8, August 2006

aug05A radio program in Nepal brings information to farmers in a language they understand.

It’s Monday, 6:30 pm on Radio Birgunj, the voice of the plains in Southeastern Nepal. Fans for kilometers in all directions huddle by their radios to listen—not to a soap opera or pop music, but to a show about bed planting, horticulture, and zero-tillage. The weekly radio show on farming, targeted specifically to rural inhabitants, is one component of a project funded by CABI to introduce and promote resource-conserving technologies to the region’s rice and wheat farmers.

Radio is often the best way to reach rural families in developing countries, and farm shows broadcast from small community stations are not unusual. But Radio Birgunj broadcasts to a population of five million Nepalese, nearly all from farm families, and the station’s only “competition” is the region’s government radio network.

Ganesh Sah, head of the Nepal Agricultural Research Council (NARC) Agricultural Implement Research Center in Birgunj and long-time CIMMYT partner, is responsible for 70 programs since the show’s launch in January, 2005. “It’s been difficult coming up with a different topic each week, but we’ve managed with just a couple repeats,” he says. The program uses a question-and-answer format, with the station’s Anita Kumwar usually putting questions to an expert guest on behalf of farmers. The show uses the region’s indigenous language and music, attracting listeners and ensuring that messages are clearly understood.

aug06

“The program has been very effective,” says Paras Thakur, a farmer in the nearby village of Tripeni. He leads a community group that is experimenting with zero-tillage, a practice whereby crops are seeded directly into field residues without plowing. “I especially liked the show about vegetables.” Eight out of ten farmers in the group have radios and listen to the broadcasts. In areas where radios are not so common, many people gather around a single radio for the show.

The program’s popularity has led the government of Nepal launch another radio farm show in the region. Is Sah worried about the competition? “Of course not: the more messages, the better,” he says. “Besides, the government program is in Nepalese, which is not the first language of Birgunj farm families.” The last show funded by the CABI project has been aired. But the project team has saved a small amount of money, so Sah hopes he and researchers from his center can hit the airwaves again soon with information to improve the livelihoods of thousands of farmers they could never meet in person.

Zero-tillage for growing wheat after rice saves water, diesel, and other inputs, and allows earlier sowing of wheat, which raises yields. The practice has been adopted by farmers on more than 2 million hectares in South Asia over the past six years. This is largely a result of work to test and promote zero-tillage and other resource-conserving practices by the Rice-Wheat Consortium for the Indo-Gangetic Plains, which includes the national agricultural research systems of Bangladesh, India, Nepal and Pakistan; several centers of the CGIAR with leadership from CIMMYT; and various advanced research institutes.

Smallholder maize farmers in Zimbabwe lack knowledge of open-pollinated varieties

CIMMYT E-News, vol 4 no. 5, May 2007

OPVs perform as well as hybrids or better under the low-input conditions of many smallholder farmers in Zimbabwe, but farmers need information and training about how properly to use them.

A new study to assess the effectiveness of a large-scale maize seed relief effort in Zimbabwe during 2003-07 shows that, even among vulnerable, small-scale farmers living on the edge of survival under the most difficult conditions, a livelihood-saving technology like quality seed of open-pollinated maize varieties (OPVs) is not enough, without knowledge about how best to use it.

Farmers can save grain of OPVs from their harvest and sow it the following year without the yield or other qualities of the variety diminishing substantially. Hybrids normally yield more than OPVs under favorable conditions, but “recycling” the seed in subsequent seasons will result in a significant loss of that yield and of other advantages; farmers must purchase fresh seed each season to retain them. “Zimbabwe farmers have historically favored hybrids, and they have limited knowledge about OPVs,” says Augustine Langyintuo, CIMMYT socioeconomist and lead author of the study. “Changing economic circumstances in the country have meant that many farmers can no longer purchase fertilizer to take best advantage of hybrid yield potential. We interviewed 597 households in 6 districts of Zimbabwe where a major seed-relief effort had, among other aims, promoted the broader diffusion of OPVs over hybrids, thereby giving smallholder farmers the possibility to save and re-use their own seed without sacrificing their meager yields.”

The seed aid effort, which was funded by British Department for International Development (DfID) and coordinated by the Food and Agricultural Organization (FAO) regional office in Harare, enlisted the assistance of 16 non-government organizations (NGOs) to distribute improved maize seed to more than 25,000 needy farmers. “The average household size in our survey group was 6.5 members, supported by a cultivated farm size of just 1.7 hectares, over 60% of which is planted to maize,” says Langyintuo. “Nearly a third of the households were headed by widowed females, a factor highly correlated with poverty.”

Under the relief program, the NGOs were expected to inform farmers of the types of seed being distributed and the need to select, store, and re-use the seed properly in subsequent seasons. Less than half the beneficiaries in the first year of the program were informed of the type of seeds to be provided, although the proportion increased to more than 60% over time. Information on OPVs was limited to the fact that they can be recycled. Less than half were ever taught how to select or store their seed.

According to Langyintuo, many farmers continue to recycle hybrids, or improperly select OPV grain for future use as seed, or—in the worst cases—eat all their grain and hope for another aid shipment to sow next year. “The relatively well-endowed farmers were more willing to recycle OPV seed. In future efforts, NGOs should perhaps target them to ensure larger-scale spillovers,” he says. “In general, whoever distributes seed of improved OPVs should provide information on proper seed selection and follow up with field-level training. Farmers should also be involved in the choice of the varieties.”

Another key issue to grapple with is the unavailability of OPV seed on the market. This stems from the unwillingness of seed companies to develop and promote OPVs, given the perception that farmers will simply recycle them and never buy fresh seed. “Zimbabwe farmers recycle both OPVs and hybrids, but if given a choice, they will purchase fresh seed whenever they can,” says Langyintuo. “OPVs perform as well as hybrids or better under the low-input conditions of many smallholder farmers in Zimbabwe, so they constitute a good option for such farmers.”

No Maize, No Food

CIMMYT E-News, vol 3 no. 10, October 2006

oct01Improved maize makes a big difference in the lives of smallholder farmers on the slopes of Mt Kenya.

It’s 4:00 am and still pitch-black on the farm of Consolata Nyaga, but she is already busy at work. With nothing but the dim light of an oil lamp to guide her she carefully milks her two cows to be ready for the buyer who passes her house just before 5:00 every morning. She will get about a dollar for the three liters of milk, a profitable start to what will be a very long working day.

The milk cows are a very small part of her “garden”; a hectare and a quarter of land. She also grows some coffee, bananas, and beans. But what makes her farm work is the half hectare of improved maize she grows every season.

Consolata is a widow living alone, but her maize, a variety released by Kenya based on material from CIMMYT and the Kenya Agricultural Research Institute (KARI), feeds her and gives her the cash to put her 10 children through school. “This season I had thirteen bags” she proclaims. “Because it is my cash crop, I must sell and send the children to school.”

Neighbors are curious and come to field days on her farm to learn about the maize, which is not only a higher yielding variety but is also quality protein maize (QPM), meaning it has enhanced levels of the essential nutrient amino acids, lysine and tryptophan.

oct02
This is a part of Kenya where maize is not only a staple; it is the food people want to eat. Farmers store it inside their homes rather than in outside bins to prevent theft. “Actually any family that has no maize, has no food,” says Father Vincent Ireri, the Development Coordinator of the Diocese of Embu. “And anytime, even when we say as a country we have no food or there is famine, the implication is that there is no maize.” Ireri leads a team that works in conjunction with Catholic Relief Services, with farmers in the district to demonstrate the advantages of the new maize varieties.

CIMMYT and KARI have been working in this area to help farmers with maize varieties that are more drought-tolerant and insect resistant and under proper management give higher yields. Much of the work in this area has been funded by the Canadian International Development Agency (CIDA). Consolata and the community group of which she is the treasurer have been quick to adopt the improved materials. Life seems to revolve around maize on Consolata’s small farm. In fact when she comes back from selling the milk each morning she immediately settles down to a hot mug of uji—a maize meal porridge. At midday she starts to prepare for the evening meal. She puts a mixture of maize and beans, called githeri, to boil on the cooking fire and then heads to her last unprepared field with a large hoe. No animal-drawn plow, just the power of one energetic maize farmer.

oct03
“Ah no! Let me tell you, if you eat potatoes and cabbages and eat rice, you cannot have energy to dig,” she says. “Yes, maize has got very big energy. You see somebody like myself after 56 years cannot dig unless you eat something good!”

Four hours later, and after a trip to the market to sell a bag of maize, dinner is ready. Neighbors, friends, and relatives have stopped by to enjoy the feast as the sun sets.

“Whenever, if I miss maize, I feel as if I am losing somehow,” Consolata says. “Maize is good. Maize is my favorite thing. And I like it. Yes.”

You can read more about the adoption of quality protein maize in the Embu district in the August E-news article The maize with the beans inside: QPM gathers a following in Kenya.

Genes explain the amazing global spread of maize

CIMMYT E-News, vol 4 no. 5, May 2007

No need to dig for ancient seeds to discover how and when maize moved from its ancestral home in Mesoamerica to become one of the world’s most widely-sown and popular food crops. New work by gene sleuths from CIMMYT and numerous maize growing countries solves the puzzle using DNA of present-day maize.

How did a crop domesticated some 7,000 years ago from a humble Mexican grass called teosinte become the number-one food crop in Africa and Latin America, and a major food, feed, and industrial crop just about everywhere else?

The incredible story of maize has been told in books, but there have always been lingering doubts, unanswered questions. If, for example, as records show, in 1493 Columbus brought maize to Spain from his visit to the warm climes and long days of the Caribbean, how is it that reliable accounts have the crop being grown in 1539 in the cold, short daylengths of Germany? That’s only 46 years later, and far too soon for such a radical adaptation in tropical maize. In another case, maize was supposedly brought to African countries like Nigeria by Portuguese colonists, but the local names for maize in that country are of Arabic derivation, suggesting that the crop likely arrived via Arabic-speaking traders.

Deciphering the history in genes

Recent work by CIMMYT and partners sheds new light on maize’s global migration. With support from Generation, a Challenge Program of the Consultative Group on International Agricultural Research, and in collaboration with nine research institutes on four continents, scientists have used DNA markers—molecular signposts for genes of interest—and new approaches to analyze nearly 900 populations of maize and teosinte from around the world. “What is emerging is a far clearer picture of the crop’s global diversity and the pathways that led to it,” says CIMMYT molecular geneticist and leader of the effort, Marilyn Warburton.

Phase I of the work was funded by PROMAIS, a European maize consortium, and focused on North America and Europe. The Generation Challenge Program commissioned Phase II, which featured global coverage and brought the number of maize populations studied to 580. In Phase III, partners are adding another 300 populations of maize and teosinte, to fill any geographical gaps. A primary objective is to gather samples of landraces—local varieties developed through centuries of farmer selection—and ensure their conservation in germplasm banks. The diversity studies apply a method developed by Warburton for using DNA markers on bulk samples of individuals from large, heterogeneous populations like those typical for maize.

The great divide: Temperate vs tropical maize

Among other things, the studies corroborate the notion that northern European maize originates from North American varieties brought to the continent several decades after Columbus’ returned, and definitely not from tropical genotypes. “The two main modern divisions of maize arose about 3,000 years ago,” says Warburton, “as maize arrived in what is now the southwestern US and, at about the same time, on the islands of the Caribbean. Temperate maize spread further north and east across North America, while tropical maize spread south. The temperate-tropical division remains today. What maintains it are differences in disease susceptibility and photosensitivity—essentially, how daylength affects flowering time. The two maize types are now so different from each other that they do not cross well, and their hybrids are not well adapted anywhere.”

The work continues and, in addition to elucidating the epic journey of maize, will help breeders to home in on and more effectively use traits like drought tolerance from the vast gene pool of maize.

The above report is largely based on a longer description of this work, “Tracing history’s maize,” that appears in Generation’s “Partner and Product Highlights 2006.”

CIMMYT Sows Second Field Trial of Promising Transgenic Drought Tolerant Wheat

March, 2005

noticias8In March, CIMMYT scientists continued their pursuit of drought tolerant wheat with the second field trial of transgenic lines carrying the DREB gene, given to CIMMYT by Japan International Research Center for Agricultural Sciences (JIRCAS). The gene, obtained from Arabidopsis thaliana, a relative of wild mustard, exhibited considerable promise in its initial field trial in 2004, and in earlier greenhouse trials (see September 2004 E-news). The project is funded by Australia’s Cooperative Research Centre (CRC) and is led by CIMMYT cell biologist Alessandro Pellegrineschi.

noticias9This second trial narrows the focus of investigation to four transgenic lines and uses a larger plot to ensure better control and analysis. It will also expose the experimental lines and control plants to both watered and drought conditions to determine their respective performance.

“In a few months when we get the results, we will follow the physiologists’ lead and see if this might be useful for producing hardy wheat for farmers in climates prone to drought,” says Pellegrineschi. He is particularly interested in identifying the promoter gene that switches on the drought response.

Small seed with a big footprint: Western Kenya, Zimbabwe, and Nepal

CIMMYT E-News, vol 4 no. 1, January 2007

jan01Farmers and community leaders in Kenya’s most densely-populated region have organized to produce and sell seed of a maize variety so well-suited for smallholders that distant peers in highland Nepal have also selected it.

According to Paul Okong’o, retired school teacher and leader of Technology Adoption through Research Organizations (TATRO), Ochur Village, Western Kenya, farmers first disliked the maize whose seed he and group members are producing. “It has small grains, and they thought this would reduce its market value,” he explains. “But when you sowed the seed, which looked small, what came out of it was not small!”

Small-scale maize farmers of the Regional Agricultural Association Group (RAAG), another community-based organization in Western Kenya, have quintupled their yields in only one year—now obtaining more than 2 tons of maize grain per hectare—using seed, fertilizer, and training from TATRO, according to RAAG coordinator, David Mukungu. “This has meant that, besides having enough to eat, farmers were able to sell something to cover children’s school fees or other expenses,” says Mukungu. “We started with six farmers the first year, but after other farmers saw the harvest, the number using the improved seed and practices increased to thirty, and we expect it will continue increasing.”

The variety whose seed TATRO grows is called Kakamega Synthetic-I. It is an open-pollinated variety—a type often preferred over hybrids by cash-strapped smallholders, because they can save grain from the harvest and sow it as seed the following year, without losing its high yield or other desirable traits. The variety is also drought tolerant, matures earlier than other local varieties, and is better for making Kenyan’s favorite starchy staple, ugali. “Women say it ‘pulls’ the water, which means you don’t need much maize flour to make a good, heavy ugali,” Okong’o explains. “These things seem small, but when taken together they weigh a lot for farmers who eat ugali as a daily staple.”

A maize that crosses many borders

Kakamega Synthetic-I was released by the KARI research station in Kakamega, Kenya. Its pedigree traces back to the work of CIMMYT and many partners in southern and eastern Africa—national maize research programs, private companies, and non-government organizations—to develop stress tolerant maize for the region’s smallholders. “Kakamega Synthetic I was selected from ZM621, a long-season, drought tolerant, open-pollinated variety now released in several African countries,” says Marianne BĂ€nziger, CIMMYT maize physiologist who took part in the creation of ZM621 and now serves as director of the center’s Global Maize Program. “The variety has also been released in Nepal, after small-scale farmers from the mid-hills chose it as one of their favorites in participatory varietal trials.” BĂ€nziger says. This highlights the role of a global organization like CIMMYT, which can draw upon and distribute public goods and expertise transcending national borders: “The center was predicated upon and has practiced collaborative science ‘globalization’ for agricultural development since its inception four decades ago—long before that term became fashionable in policy circles.”

Finding and filling entrepreneurial niches

By reducing risk for small-scale farmers, varieties like Kakamega Synthetic-I encourage investment in other amendments, like fertilizer, that can start smallholders on an upward spiral out of low-input, subsistence agriculture. Good varieties also entice enterprising farmers and community-based organizations like TATRO into potentially profitable businesses like seed production, for niches inadequately served by existing companies. “We observe the seed production regulations of the KEPHIS, the Kenyan plant health inspectorate, and would like to work toward certification of our organization, to be able to sell certified seed in labeled packages and fetch better prices,” says Okong’o. TATRO is currently producing and marketing just under 2 tons of Kakamega Synthetic-I—enough to sow more than 70 hectares—each year. The lack of effective informal seed production and distribution systems limits the spread of improved open pollinated maize varieties and farming practices in eastern Africa, according to Stephen Mugo. CIMMYT maize breeder in the region, Mugo also coordinated the former, Rockefeller Foundation-funded project “Strengthening maize seed supply systems for small-scale farmers in Western Kenya and Uganda” that involved TATRO and similar farmer organizations. “Improved varieties raised yields in the past and could do so again,” he says, “but only about one-fifth of the region’s farmers grow improved varieties.”

Helping to Reinvigorate Agriculture in Afghanistan

CIMMYT E-News, vol 2 no. 8, August 2005

Ghulam m Aqtash, Executive Director, KRA

“The maize brought by CIMMYT and implemented by Kunduz Rehabilitation Agency is doing wonders.”
Years of war (1979-1989) and subsequent internal instability, plus a prolonged drought and an earthquake, devastated Afghanistan’s agricultural infrastructure, production capacity, and agricultural research capabilities. As a result, agricultural production fell to an estimated 45% of 1978 levels, with crop yields declining to about 50% of pre-war levels.
Wheat is the number-one staple crop in Afghanistan, and maize is the third. Together they occupy 80% of the area planted to annual crops in the country. A central aim of CIMMYT in Afghanistan is to make improved, high quality seed of both crops available to farmers, along with appropriate crop management technologies. To date CIMMYT has responded to Afghanistan’s most urgent needs by:

  • Distributing 300 tons of quality seed of the locally-adapted wheat MH-97 to 9,000 farmers in four provinces of Afghanistan.
  • Producing and delivering tons of breeder’s and foundation maize seed.
  • Planting 35 wheat variety trials at 6 sites and 24 maize trials at 8 sites to identify additional materials suited to farmers’ needs.
  • Training Afghan researchers through courses in-country and at CIMMYT in Mexico.

CIMMYT has collaborated with Afghan researchers for over three decades—even during the war. Thanks to the Swedish Committee for Afghanistan and the FAO, Afghan researchers maintained contact with the Turkey-CIMMYT-ICARDA International Winter Wheat Improvement Program (IWWIP) and continued to select the best new wheats from international nurseries. The new seed moved from farmer to farmer; without it, people would have suffered even more hunger and malnutrition than they did. All winter and facultative wheat cultivars currently registered in Afghanistan are derived from those nurseries. In total, several hundred CIMMYT wheat and maize nurseries have been evaluated in Afghanistan over the past 30 years.

Recent Update from the Field

kunduzAn important component of a current ACIAR-funded project (“Wheat and Maize Productivity Improvement in Afghanistan”) has included collaborative work with farmers and non-government and international organizations to verify in farmers’ fields the performance and acceptability of improved wheat and maize varieties. For wheat, the project uses two approaches:

  1. A traditional approach where demonstrations are planted in farmers’ fields and the farmer assessments are recorded informally through topic focused interviews during field days. The varieties included in these demonstrations are released in the country and made available where security allows. Using this approach in Parwan Province, farmers showed a keen interest for the variety ‘Sohla,’ which yielded well and showed superior resistance to diseases like rust. The project is helping to ensure that demand for seed of the variety is met.
  2. A participatory technology development approach implemented by the Aga Khan Foundation brings farmers to research stations to observe yield trials of promising varieties. Farmers identify preferred varieties with red tags; their assessments determine the selection of wheat lines for advancement and subsequent release.

For maize, the project provided non-government organizations with seed of open-pollinated varieties that were distributed to rural communities. Farmer testing and feedback resulted in the identification of two promising varieties: Rampur 9433 and PozaRica 8731. Farmers said the varieties performed well but did not mature quickly enough to fit local cropping systems, so project participants are identifying earlier-maturing varieties. To offer farmers sufficient seed, the project is pursuing two approaches:

  1. A formal scheme whose main partners are the Agricultural Research Institute of Afghanistan (ARIA) and the FAO, through the Improved Seed Enterprise (ISE), and under which breeder’s seed will be offered to recognized producers of certified seed.
  2. Informal farmer-to-farmer distribution systems, which have resulted in up to a 10-fold increase in some areas under improved varieties. For example, the Norwegian Project Office-Rural Rehabilitation Association for Afghanistan (NPO-RRAA) reported that farmers who had planted open-pollinated varieties from the project in 2003 had bartered and sold more than two tons of seed of the varieties in 2004.

afghanFarmers

The project has built human capacity through in-country, technical workshops, five of which have been conducted since 2000 on topics including: agricultural development potential and constraints in specific zones; yellow rust and field scoring for the disease; research methodologies; variety evaluation; and several field days. The workshops have drawn 70 participants, including farmers, workers from non-government organizations, and officers from research stations.

CIMMYT partners in Afghanistan include:
  • The Future Harvest Consortium to Rebuild Agriculture in Afghanistan, funded by USAID and coordinated by ICARDA.
  • AusAID and the Australian Centre for International Agricultural Research (ACIAR).
  • The FAO.
  • The International Fertilizer Development Center (IFDC)-USAID.
  • The French non-government organization, ACTED.
  • The Aga Khan Development Network.
  • Improved Seed Enterprise.
  • The Afghan Ministry of Agriculture.
  • ARIA.

Molecular detection tools for African maize breeders

CIMMYT E-News, vol 3 no. 1, January 2006

MolecDetectionA new DNA detection service provided by CIMMYT and KARI responds to African researchers’ calls for modern technology.

African maize breeders now have access to state-of-the-art biotechnology tools thanks to a service launched by CIMMYT and the Kenya Agricultural Research Institute (KARI). Housed within the laboratories at the International Livestock Research Institute (ILRI) headquarters in Nairobi, under the Canadian International Development Agency (CIDA)-funded Biosciences Eastern and Central Africa (BECA) platform, the lab offers and trains researchers in the use of molecular marker techniques.

The molecular markers are DNA snippets that help researchers locate and select for genes associated with traits of interest, including resistance to pests and diseases, or tolerance to stresses like drought. With markers, breeders can cut the time and money needed to develop plant types that possess such useful traits. Until now, this capability had been unavailable to scientists in sub-Saharan Africa, outside of South Africa.

Led by CIMMYT biotechnologist Jedidah Danson and supported by the Rockefeller Foundation, the service now has its hands full of requests from breeders working with CIMMYT, national agricultural research systems, local seed companies, and universities. “They’ve learnt of the service entirely through word-of-mouth,” she says. “It’s especially attractive because current funding allows us to offer the service free, so more breeders are exposed to the technology.”

Breeders using the service are especially interested in finding ways to incorporate resistance to maize streak virus, a disease endemic in much of sub-Saharan Africa and in enhancing the nutritional quality of herbicide tolerant maize, originally developed as part of a package to control the parasitic witch weed.

“Marker assisted selection is an important tool for breeders in Africa. CIMMYT and KARI must be lauded for being the first in the region to provide the service to public sector researchers,” says Richard Edema, molecular breeder at Makerere University, Uganda. Edema is also coordinator of the African Molecular Marker Application Network, a consortium of about 100 biotechnologists and breeders from across sub-Saharan Africa.

Danson is building a database of markers for genes for resistance to important pests and diseases, including maize streak virus, gray leaf spot, the parasitic weed Striga, and northern corn leaf blight. She also helps train breeders in the effective use of markers. “Clearly, our partnership to support African breeders was long overdue,” she says.

Millennium Village Celebrates Harvest

CIMMYT E-News, vol 2 no. 9, September 2005

millenium1CIMMYT maize helps villagers quadruple their yields.

The excitement was palpable—and with good reason. “The last time we saw maize like this was in the 1970s!” said Euniah Akinyi Ogola, holding her freshly harvested maize cobs—each as long as her forearm—as the 5,000 residents of Bar Sauri village in western Kenya celebrated their maize harvest.

Euniah is a villager in the world’s first ‘millennium village’ of the UN’s Millennium Project. The village hopes to show that with modest investment and support, it is entirely possible to pull people out of hunger and poverty and set them on the road to prosperity. One of the first steps in the five-year process is to end hunger by improving the village’s agriculture.

With the drying up of state subsidies for small farmers in the 1980s and changes in agricultural programs in the 1990s, many Kenyan villages suffered a downward spiral in maize production. When the village project started in 2004, most farmers in Sauri were harvesting well under a ton of maize per hectare, insufficient to see a household from one crop to the next. The shortage of maize—the main staple food—coupled with malaria and HIV-Aids, effectively stymied Sauri villagers’ chances for a better life.

millenium2

To address the biting hunger Pedro Sanchez, co-chair of the UN Millennium Project Hunger Task Force, and his team introduced two maize hybrids to the village. Planted on all 300 hectares of village, both varieties were developed by CIMMYT’s Africa Maize Stress (AMS) project funded by IFAD, SIDA, BMZ, and the Rockefeller Foundation.

“We were looking for the best maize varieties available in Kenya,” says Sanchez, who did not want to take any chances when selecting the maize for the village. In addition to the new maize seed, the villagers received fertilizer and were shown the proper way to plant and tend their maize. Hard work and good rains completed the picture, leading to a bumper crop of four tons per hectare that astonished the villagers, project staff, and observers worldwide.

At the recent harvest festival, UNICEF Executive Director Anne Veneman and Professor Jeffry Sachs, UN Special Envoy on the millennium development goals (MDGs), both praised the success of the village. Sachs said the project would now work with the villagers to construct safe storage facilities for their current and future harvests and start planting more vegetables and other high-value crops.

Alpha Diallo, leader of the AMS project, says he was thrilled that the CIMMYT varieties met the MDG challenge: “The hybrids are high yielding, but are also able to resist diseases and other environmental stresses, thanks to our targeted, long-term breeding efforts,” he says.

Conservation by the numbers: Reducing genetic drift in crop gene bank collections

CIMMYT E-News, vol 3 no. 1, January 2006

conserving1CIMMYT’s biometrics team receives special recognition for advancing the science behind crop genetic resource conservation.

The nightmare of a gene bank curator: You have a collection of 25,000 precious, unique samples of maize seed; one of the world’s most extensive. You store it carefully, keep it cold and dry, but—little by little over the years—the seed dies! Eventually you’re left with so many packets of useless kernels, and the precious genetic diversity they once embodied is lost to humanity forever.

To keep this very bad dream from becoming a reality, Suketoshi Taba, head of maize genetic resources at CIMMYT, and his team constantly monitor the germination capacity of collections. When it drops below 80-85%, they take viable seed from the endangered accession (the term for individual, registered samples in the bank), sow it under controlled conditions, and harvest enough from progeny to replenish the accession. Known as “regeneration,” the process sounds simple, but in fact must be done painstakingly to capture a faithful snapshot—rather than a faded copy—of the genetic diversity from the original accession.

The Crop Science Society of America recently bestowed the honor of “2004 Outstanding Paper on Plant Genetic Resources” on an article by CIMMYT biometricians that provides models for proper handling of repeated cycles of regeneration. Their work, which was funded by the Australian Grains Research and Development Corporation (GRDC), is particularly relevant for outcrossing, genetically diverse crops like maize, legumes, or sorghum, to name just a few.

“For maize regeneration, we use artificial pollination, to avoid out-crossing with pollen from other maize fields,” says Taba. “But even the individuals in a maize population or accession are genetically diverse. How can we decide on the best way to pollinate the plants, or how many ears we need to harvest, or how many and which seeds to choose from each ear?” According to Taba, the danger is ending up with a sample that differs from the genetic make-up of the original. And with each successive cycle of regeneration, you can drift further and further.

Building on a strong body of work in this area by CIMMYT biometricians since the 1980s, the award-winning paper refines and expands the statistical model and provides reliable computer simulations. “Among other things, the simulation model shows exactly how many alleles are likely to be lost through various sampling and regeneration strategies,” says Jiankang Wang, CIMMYT biometrician who is first author of the study. “It describes how different strategies can affect the conservation of alleles and gives gene bank curators options that can be tailored for specific types of accessions.”

Jiankang Wang says he and his co-author, CIMMYT biometrician JosĂ© Crossa, are now working with Taba to apply the paper’s model in managing CIMMYT’s maize gene bank collection. “Many other gene banks will find this approach useful,” says Crossa, explaining why their study received the award. “For example, we collaborate closely with the National Center for Genetic Resources Preservation in Fort Collins, Colorado, in the USA. They can apply the same principles in their regeneration work.”

Jiankang Wang was excited by the recognition and the fact that peers might find his work useful. “In middle school, teachers saw I had talent and told me to specialize in mathematics, but at the university I discovered that I was most interested in the practical applications of mathematics,” says Jiankang Wang. “Using science to help preserve the world’s crop genetic resources is a great satisfaction.”

Biotech in Bogor

CIMMYT E-News, vol 2 no. 11, November 2005

indo2Young Indonesian researchers are reaping the benefits of collaboration with CIMMYT and at the same time helping farmers in their country.

It could be a biotech laboratory almost anywhere in the world, but this one is the Indonesian Center for Agriculture Biotechnology and Genetic Resources Research and Development in Bogor, Indonesia. What makes it remarkable is that just ten years ago Indonesia had virtually no agricultural biotechnology capacity at all. At the lab benches, in standard issue white lab coats, two of Indonesia’s brightest students, each with a strong commitment to helping their country, are doing the painstaking work that molecular biology requires and their PhD supervisors demand.

Marcia Pabendon is doing a maize diversity study, using DNA fingerprinting to identify maize germplasm from diverse sources to use as parents in a breeding program to find resistance for downy mildew and drought tolerance. These are the two most serious production constraints for maize in Indonesia, where half of all maize is grown in dry land areas. By analyzing the DNA she can be sure male and female parents in the breeding program are not closely related, which is detrimental to the hybrids.

Mohamed Azrai wants to convert local maize varieties into quality protein maize, maize with higher levels of the amino acids lysine and tryptophan, which occur at low levels in most maize and could result in protein deficiencies for anyone who relies heavily on maize in their diet. “I want my research to result in quality protein maize varieties that farmers will use,” he says. “Maybe quality protein maize can help solve the problem of protein malnutrition on my country.”

indonesia1“This is the untold story of the quiet biotech revolution going on in maize breeding in Asia,” says CIMMYT’s Luz George. “It is a successful transfer of technology from CIMMYT to developing countries which has now found direct application in the work of national program maize breeders.”

It began with the Asian Maize Biotechnology Network, AMBIONET, which was funded by the Asian Development Bank and which George coordinated. K.R. Surtrisno, the Director of the biotech center in Bogor, says the capacity enhancement the network provided was vitally important. “The network has given us, through CIMMYT, genotype data and training in mapping. Now the government of Indonesia has made a commitment to support and improve our facility, just in time to do useful work for farmers.”

His thoughts are echoed by Marsum Dahlan, the head of the Breeding and Germplasm section of the Indonesian Cereals Research institute. “When AMBIONET came we thought not only to help farmers but also to create capacity,” he says. “This technology will help us, though we must still combine it with tests in the field.”

AMBIONET and the work with CIMMYT have proven very valuable to agricultural biotechnology in Indonesia. “Even though the AMBIONET program is over, we still maintain collaboration with CIMMYT,” says Surtrisno. That is good news for Indonesia and good news for promising young researchers like Mohamed and Marcia.

Farmers Say: “Kill Striga!”

CIMMYT E-News, vol 3 no. 2, February 2006

feb_strigaKenyan farmers’ verdict is out: “Ua Kayongo is the best Striga control practice and we will adopt it.”

Farmers in western Kenya overwhelmingly favor imidazolinone-resistant (IR) maize seed coated with a low dose of this herbicide to kill Striga, a highly-invasive parasitic weed that infests 200,000 hectares of Kenya’s farmland and causes crop losses worth an estimated US$ 50 million each year. This was a key finding of a recent, independent study commissioned by the African Agricultural Technology Foundation (AATF) to the Western Regional Alliance for Technology Evaluation (WeRATE; includes non-governmental organizations, farmer associations, and extension workers). Nearly 5,300 farmers in 17 districts of western Kenya evaluated eight recommended Striga management practices.

Farmers have dubbed the winning maize “Ua Kayongo”—literally, “kill Striga” in a mixed vernacular. In July 2005, the Kenya Agricultural Research Institute (KARI) and private seed suppliers started to commercialize four hybrid varieties of Ua Kayongo in Kenya.

The maize’s herbicide resistance is based on a natural mutation in the crop. Its development into Ua Kayongo was through global cooperation involving CIMMYT; KARI; the Weizmann Institute of Science, Israel; and BASF-The Chemical Company, funded by the Rockefeller Foundation and BASF. In the new practice, Ua Kayongo seed is coated with BASF’s Strigaway¼ herbicide, which kills Striga seedlings below ground. This prevents them from fastening to the roots of maize seedlings, from which they suck away water and nutrients.

feb_graphFarmers in the WeRATE evaluations were able to plant the new maize using their normal husbandry methods, including intercropping with legumes and root crops. “I’ve been pulling and burying Striga on my 5-acre farm for the past 17 years and the problem has only grown worse,” said Rose Katete, a farmer from Teso; “Ua Kayongo has provided the best crop of maize that I’ve ever grown!”

Katete’s observations bear out CIMMYT and partners’ findings from several years of field trials: “Under Striga-infested conditions, the new maize hybrids out-yield the checks by more than 50%, and provide near-total Striga control,” says Marianne BĂ€nziger, Director of the CIMMYT Maize Program.

Over the next five years, the new Striga control package will be made available to farmers in Tanzania, Uganda, and Malawi, and eventually, other countries of sub-Saharan Africa with a Striga weed problem.

Gene Flow Study Explores How Farmers Keep Maize Thriving and Changing

June, 2005

gene_photo1What role do farmers play in the evolution of maize diversity? How extensive are the farming networks and other social systems that influence gene flow? These and other questions are helping researchers to combine knowledge of the genetic behavior of plants with information on human behavior to understand the many factors that affect maize diversity.

Outside a straw and mud-walled house in rural Hidalgo, Mexico, with chickens walking around and the smell of the cooking fire wafting through the air, CIMMYT researcher Dagoberto Flores drew lines with a stick in the red earth as he explained to a farmer’s wife how maize seed should be planted for an experiment. Along with CIMMYT researcher Alejandro Ramírez, Flores was distributing improved seed in communities where they had conducted surveys for a study on gene flow.

The movement of genes between populations, or gene flow, happens when individuals from different populations cross with each other. CIMMYT social scientist Mauricio Bellon is leading a study that aims to find out the impact of farmers’ practices on gene flow and on the genetic structure of landraces. It will document how practices differ across farming systems, analyze their determinants, figure out how much farmers control gene flow, and explore gene flow’s impacts on maize fitness and diversity and on farmers’ livelihoods.

gene_photo2The farmers visited by Flores and Ramírez in early June near Huatzalingo and Tlaxcoapan, Hidalgo are from just 2 of 20 study communities spanning ecologies from Mexico’s highlands down to the lowlands. Six months earlier, when farmers in these communities responded to researchers’ survey question, they asked some questions of their own: What does CIMMYT do? How can we get seed?

The team made it a priority to give the farmers what they requested for free. They drove around in a pick-up truck with seed they had acquired from CIMMYT scientists. They brought black, white, and yellow varieties that were native to the area and had been improved with weevil and drought resistance, and they also brought three CIMMYT varieties that were well adapted to a similar environment in Morelos, Mexico. They explained to the farmers how each variety should be planted in separate squares to facilitate pure seed selection.

“It’s a way to thank them, to bring something back to the communities,” says Bellon. Bringing improved germplasm for experimentation to interested small-scale farmers also allows researchers to get feedback in a more systematic way. The farmers will produce the maize independently, and they can save or discard seed from whichever varieties they choose. The team also distributed seed to farmers in Veracruz, and they plan to return after flowering and at harvest time to see how the improved seed fares compared with native varieties. That component of the project could be the beginning of further research in collaboration with farmers.

gene_photo3Farmers in the survey area of rural Hidalgo grow maize on the poorest, most steeply sloping land and struggle with soil diseases, low soil fertility, leaf diseases, low grain prices, and limited information about the use of chemical herbicides. Strong wind, rain, and hurricanes damage crops. Landslides cause erosion. Some farmers have access to roads and can transport their harvest by vehicle, but some farms located far from the communities have no highway access. The paths to farmers’ fields can be so narrow that not even cargo animals can maneuver on them with loads, so farmers must carry the harvest on their backs. Some walk 10 kilometers up and down slopes with heavy bags on their backs.

Many people grew coffee around Huatzalingo until about 10 years ago when the price plummeted. A kilogram of coffee used to fetch a price of about 20 pesos, or US$ 2. Now it fetches about five pesos, or 50 cents, per kilo, and even less during harvest time when the crop is abundant. Coffee producers in the area receive average government subsidies of between 125 and 300 pesos, or between US$ 10-30. One effect of the price drop has been increased immigration to Mexico City, to the city of Reynosa near the US border, and to lowland areas where orange cultivation is booming.

Partly in response to the crisis, farmers have started diversifying into alternative crops such as vanilla, citrus fruits, bananas, sugar cane, sesame, beans, chayote, chili peppers, and lentils, but the poor soils do not favor more lucrative crops. Maize is still the most important agricultural product in people’s diets in this area, and farmers grow it primarily for family consumption. They exchange seed with friends, neighbors, and producers in nearby communities, and they have conserved diverse native varieties.

In Mexico, maize has such great genetic diversity because farmers’ practices encourage the further evolution of maize landraces. Maize was domesticated about 6,000 years ago within the current borders of Mexico. Farmers created a variety of races to fit different needs by mixing different maize types, and they still experiment like that to this day. They save seed between seasons and trade seed with each other, and the wind carries pollen between different cultivars to create new mixtures.

“They are not artifacts in a museum,” Bellon says about landraces. “They are changing, they are moving.” Seed selection has a great impact on gene flow. Poor farmers typically exchange seed with each other, but little has been documented about the social relations that drive seed systems. With growing concerns about a loss of crop genetic diversity and a need to conserve genetic resources in recent years, it is important to understand the social principles of seed flow (and ultimately gene flow) in Mexico. The study findings will assist in exploration of the potential impact of transgenes. The researchers will develop models to try to predict how a transgene would diffuse and behave after it has been in a population for 10 or 20 years.

By learning about the relationships between farmers’ practices and gene flow, researchers hope to promote more effective policies regarding the conservation of diversity in farmers’ fields, the distribution of improved germplasm, and transgene management. Funded by the Rockefeller Foundation, the study combines social science with genetics to connect social and biological factors in maize varieties. Molecular markers will help show how much gene flow has occurred over time between the Mexican highlands and lowlands.

Researchers used geographic information systems to choose varied environments for the survey. Starting in October 2003, they sampled maize populations and interviewed the male and female heads of 20 households in each community for a total of 800 intensive interviews in 400 households. They asked about topics such as principal crops, planting cycles and methods, maize varieties, machinery and tools, infrastructure, language, seed selection, fertilizer, pest and weed control, plant height, harvest, transportation, production problems, maize uses, the sale and demand of different varieties, knowledge about maize reproduction, husk commercialization, and level of migration.

Preliminary findings have already surprised Bellon. A growing market for maize husks, which are used to wrap traditional foods such as tamales, is changing the economics of maize production. Owing to increasing demand from the US, husks have become more commercially important and profitable than grain in some communities. Facing abysmally low grain prices, the success of husk production has caused some producers to seek maize varieties with high quality husks, almost regardless of grain quality.

Bellon was also surprised at the lack of improved varieties in the areas they studied. Farmers tended to seek out and plant native varieties instead of hybrids. Some farmers thought hybrids were expensive, produced poor quality husks, and required good land, chemicals, and fertilizer, but they thought native varieties adapted easily to marginal local conditions.

The study grew out of a six-year project in Oaxaca that examined the relationship between farmers’ practices and the genetic structure of maize landraces and seed flow among farmers. It also explored the implications of transgenic technologies. However, while the Oaxaca project examined a few communities located in one environment, the idea with this follow-up study was to examine many locations in the same and different environments. In that way researchers can find out if gene flow is localized or if it crosses between regional environments. “It’s the same research model on a broader scale,” says Bellon.
