As staple foods, maize and wheat provide vital nutrients and health benefits, making up close to two-thirds of the worldâs food energy intake, and contributing 55 to 70 percent of the total calories in the diets of people living in developing countries, according to the U.N. Food and Agriculture Organization. CIMMYT scientists tackle food insecurity through improved nutrient-rich, high-yielding varieties and sustainable agronomic practices, ensuring that those who most depend on agriculture have enough to make a living and feed their families. The U.N. projects that the global population will increase to more than 9 billion people by 2050, which means that the successes and failures of wheat and maize farmers will continue to have a crucial impact on food security. Findings by the Intergovernmental Panel on Climate Change, which show heat waves could occur more often and mean global surface temperatures could rise by up to 5 degrees Celsius throughout the century, indicate that increasing yield alone will be insufficient to meet future demand for food.
Achieving widespread food and nutritional security for the worldâs poorest people is more complex than simply boosting production. Biofortification of maize and wheat helps increase the vitamins and minerals in these key crops. CIMMYT helps families grow and eat provitamin A enriched maize, zinc-enhanced maize and wheat varieties, and quality protein maize. CIMMYT also works on improving food health and safety, by reducing mycotoxin levels in the global food chain. Mycotoxins are produced by fungi that colonize in food crops, and cause health problems or even death in humans or animals. Worldwide, CIMMYT helps train food processors to reduce fungal contamination in maize, and promotes affordable technologies and training to detect mycotoxins and reduce exposure.
The newly released CGIAR Research Program on Maize (MAIZE) Annual Report 2018 highlights significant development outcomes and impacts through varietal release, scale-up, delivery and adoption of CIMMYT- and IITA-derived climate-resilient and nutritionally enriched maize varieties.
In 2018, national partners released 81 unique CGIAR-derived maize varieties across Africa, Asia and Latin America. Of these varieties 14 were hybrid combinations, showing that regional and multinational seed companies use MAIZE’s improved germplasm to develop and release improved maize hybrids. 20 of the released varieties are nutritionally enriched â provitamin A, quality protein maize (QPM), high-zinc â the result of the MAIZE partnership with the CGIAR Research Program on Agriculture for Nutrition and Health (A4NH; HarvestPlus).
MAIZE and partners have made great strides in 2018 combatting major pest and disease challenges such as maize lethal necrosis (MLN) and the devastating fall armyworm. MAIZE researchers found that sustainable intensification practices in combination with stress-tolerant maize led to higher yield gains during the El Niño year in Southern Africa. Meanwhile, a crop growth modelling study quantified the impact of climate change on maize and found combined drought and heat stress tolerance has a benefit at least twice that of either one alone.
The newly released CGIAR Research Program on Wheat (WHEAT) Annual Report 2018 highlights joint achievements that are making an invaluable contribution to global food security, especially for the 2.5 billion people who depend on wheat for their livelihoods.
The report describes work with national and global partners using state of the art technology to measure traits and performance for faster development of high-yielding, heat- and drought-tolerant varieties; rapidly diagnosing diseases in farmersâ fields; supporting gender equality in agricultural innovations, and much more.
With its national partners, WHEAT released 48 new CGIAR-derived wheat varieties to farmers in 2018, and developed 11 innovations related to farm management practices or social sciences.
The International Maize and Wheat Improvement Center (CIMMYT) is offering a new set of improved maize hybrids to partners in South and South East Asia and similar agro-ecological zones, to scale up production for farmers in these areas.
National agricultural research systems and seed companies are invited to apply for the allocation of these pre-commercial hybrids, after which they will be able to register, produce and offer the improved seed to farming communities.
The deadline to submit applications to be considered during the next round of allocations is August 15, 2019. Applications received after that deadline will be considered during the following round of product allocations.
Information about the newly available hybrids, application instructions and other relevant material is available below.
To apply, please fill out the CIMMYT Improved Maize Product Allocation Application Forms, available for download at the links below. Each applicant will need to complete one copy of Form A for their organization, then for each hybrid being requested a separate copy of Form B. Please be sure to use these current versions of the application forms.
CIMMYT researcher Bekele Abeyo remarked at the International Wheat Congress that there are hardly any African countries self-sufficient in wheat, and that food security in Africa is dependent on wheat production.
Matthew Reynolds, CIMMYT researcher and head of the Heat and Drought Wheat Improvement Consortium (HeDWIC), noted that the consortium has already benefited nine African countries and stresses the importance of future work in this area.
Agricultural researchers, who have teamed up to boost harvests and fight the major blight of wheat rust are now forming an international consortium in a bid to make wheat stand up to worsening heat and drought.
“There was a real shift in terms of the intensity of what we do together when we became aware of climate change,” said Hans-Joachim Braun, who heads the global wheat program for the International Maize and Wheat Improvement Center (CIMMYT), based in Mexico. For each 1 degree Celsius global temperatures rise above pre-industrial times, wheat harvests drop 5-8%, he said. That means the world will likely see a 10% drop in harvests even if governments hold global warming to “well below” 2C, as they have agreed, he said – and that drop would come even as the world’s population grows and demand for food rises.
Finding ways to breed wheat that can cope better with heat could help farmers from Australia to India and China, as well as the people who depend on their grain, he said. “It doesn’t matter where you use this trait – it will have an impact,” Braun said. Read more here.
Most African countries have good potential for boosting wheat production if they are supported with technology, innovation and research, said Bekele Abeyo, a senior scientist with the International Maize and Wheat Improvement Center (CIMMYT).
Abeyo, who is based in Ethiopia, which is one of the top wheat-producing countries in Africa, was speaking to BBC Newsday from the International Wheat Congress in the city of Saskatoon in Canadaâs western wheat growing province of Saskatchewan.
In Ethiopia, a third of local demand is satisfied by imports, Abeyo said, adding that to reduce import bills, the government is trying to expand wheat production and irrigation in the lowlands where there is high potential for wheat production.
Climate change in Ethiopia and across sub-Saharan Africa is affecting yields, so scientists are working on producing drought-tolerant varieties of wheat. They are also producing biofortified varieties of wheat to help meet nutritional demand for zinc and iron.
More than 800 delegates, including researchers from the CGIAR Research Program on Wheat, CIMMYT, the International Center for Agricultural Research in the Dry Areas (ICARDA), the International Wheat Yield Partnership (IWYP), Cornell Universityâs Delivering Genetic Gain in Wheat project (DGGW), the University of Saskatchewan and many other organizations are discussing the latest research on wheat germplasm.
The CGIAR Research Program on Wheat (WHEAT), led by the International Maize and Wheat Improvement Center (CIMMYT), is a founding member of the G20 Wheat Initiative, a co-host of the conference.
Wheat provides 20% of all human calories consumed worldwide. In the Global South, it is the main source of protein and a critical source of life for 2.5 billion people who live on less than $2 a day. Wheat is central to conversations about the rural environment, agricultural biodiversity and global food security.

In the Green Revolution era, the focus for wheat breeders was on boosting yields to feed more people, but today the challenge is not only to increase production on smaller plots of land, but also to improve nutritional quality, said CIMMYT wheat breeder Velu Govindan, during an interview on BBC Newsday.
At the opening session of the International Wheat Congress 2019 in Saskatoon, the director general of the International Maize and Wheat Improvement Center (CIMMYT), Martin Kropff, told a gathering of 900 wheat scientists that, with CIMMYT support, Bangladesh developed blast resistant wheat in the quickest possible time.

Tabitha Kamau, 29, is scrutinizing a maize demonstration plot on which 12 different varieties were planted in November 2018. âWhat I am looking for is a maize variety that produces a lot, even when there is scarce rainfall,â says the single mother of three, who lives in Katheini, in Kenyaâs Machakos County, on a quarter of an acre of land.
Together with 350 other smallholder farmers from Katheini and neighboring villages, Kamau is assessing the maize crops and ranking them based on her preferred traits.
Like her peers when asked what makes a good maize variety, she gives high scores to drought-tolerant varieties and those that can yield large and nicely filled cobs despite the dry spell that has affected the area over the last two months.
For five years, Kamau has been planting KDV4, a drought-tolerant open pollinated variety on the family land and another piece of leased plot. This early variety matures in 100 to 110 days and is adapted to dry mid-altitude conditions.

KDV4 was released by the Kenya Agricultural & Livestock Research Organization (KALRO) using the International Maize and Wheat Improvement Center (CIMMYT)âs germplasm. It is currently marketed by Dryland Seed Limited and Freshco Seeds, targeting farmers in the water-stressed counties of Kitui, Machakos and Makueni, in the lower eastern regions of Kenya.
The early maturing of varieties like KDV4 presents a good opportunity for its adopters, says Kamau. âIf I am able to harvest in three and a half months or less, compared to four months or more for other varieties, I can sell some grain to neighbors still awaiting their harvest who want to feed their families.â
âI heard of new varieties that can germinate well and produce lots of leaves,â explains Catherine Musembi. This farmer from Kivaani looks for maize that performs well even under heat and drought. She likes maize plants with high biomass, as the foliage is used to feed the familyâs three cows and two goats.

Farmersâ picks
The International Maize and Wheat Improvement Center (CIMMYT) has been undertaking participatory maize variety evaluations since 2016 in Kenya, Rwanda, Tanzania and Uganda. Every year, during the main maize growing season, researchers plant on-farm trials that can be evaluated by farmers.
Kamau and Musembi attended a selection trial in Machakos County, facilitated by a team from KALRO on February 18-19, 2019. This exercise was part of the 2018 mid-season evaluations, which were followed up by end-season assessments a month later.
Participatory farmer evaluations are used to give crucial feedback to CIMMYTâs maize breeding work. First, farmers get an opportunity to state what traits are important for them and rank them according to their importance. Then, participants evaluate varieties planted in the trial and give a score on individual trait and the overall performance for each variety planted. And they conclude the exercise by rating the best three plots.
In the drier eastern part of Kenya, farmers might be more interested in traits such as drought tolerance, early maturity and disease resistance. In central Kenya, where dairy farming is commonly practiced, a variety with more biomass could be preferred.
âOur work is to tease out the information regarding which traits contribute to a good score in the overall score,â explains Bernard Munyua, a socioeconomics research assistant at CIMMYT. Statistical analysis of the farmersâ score cards will reveal if the initial rating of criteria plays a strong role in the final overall appreciation of a variety. For instance, farmers may give high importance to height or biomass, yet it may not play a role in their ranking of best varieties.
âSuch data is important for maize breeders to support future variety improvement work,â Munyua notes. âMoreover, by disaggregating the farmers opinions by region and socioeconomic attributes such as gender, education and income, we can define the priority traits by region or farmersâ socioeconomic profiles. It helps better target maize breeding work according to the needs on the ground and gives useful knowledge to seed companies for their seed marketing strategy,â he adds.
For instance, in the drier eastern part of Kenya, farmers might be more interested in traits such as drought tolerance, early maturity and disease resistance. In central Kenya, where dairy farming is commonly practiced, a variety with more biomass could be preferred. In western Kenya, they could be more interested in grain yields and cob characteristics to improve their sales after harvest.

Agnes Nthambi, the farmer who hosted the demonstration plot, is very positive about her participation, as she learned about some of the ideal agronomic practices as well as the performance of new varieties. âOn this trial, I learned that spacing was about two times shorter than we are generally used to. Even with the more constricted spacing, the maize has performed much better than what we are used to seeing,â she says. She also learned that fertilizer is applied at the time of planting. In her case, she normally applies fertilizer much later after germination has already occurred.
Nthambi says her family cannot afford losing both the fertilizer and the seed in case the rains fail. This time, she expects a good harvest from the one-acre farm, to supplement her familyâs income.
SASKATOON, Canada (CIMMYT) â Amid global efforts to intensify the nutritional value and scale of wheat production, scientists from all major wheat growing regions in the world will gather from July 21 to 26, 2019 at the International Wheat Congress in Saskatoon, the city at the heart of Canadaâs western wheat growing province, Saskatchewan. The CGIAR Research Program on Wheat (WHEAT), led by the International Maize and Wheat Improvement Center (CIMMYT), is a founding member of the G20 Wheat Initiative, a co-host of the conference.
Wheat provides 20% of all human calories consumed worldwide. In the Global South, it is the main source of protein and a critical source of life for 2.5 billion people who live on less than $2 (C$2.60) a day.
In spite of its key role in combating hunger and malnutrition, the major staple grain faces threats from climate change, variable weather, disease, predators and many other challenges. Wheatâs vital contribution to the human diet and farmer livelihoods makes it central to conversations about the rural environment, agricultural biodiversity and global food security.
More than 800 delegates, including researchers from the CGIAR Research Program on Wheat, CIMMYT, the International Center for Agricultural Research in the Dry Areas (ICARDA), the International Wheat Yield Partnership (IWYP), Cornell Universityâs Delivering Genetic Gain in Wheat project (DGGW), the University of Saskatchewan and many other organizations worldwide will discuss the latest research on wheat germplasm.
âWe must solve a complex puzzle,â said Martin Kropff, CIMMYTâs director general. âWheat must feed more people while growing sustainably on less land. Wheat demand is predicted to increase 60% in the next three decades, while climate change is putting an unprecedented strain on production.â
âThe scientific community is tackling this challenge head-on, through global collaboration, germplasm exchange and innovative approaches. Researchers are looking at wheatâs temperature response mechanisms and using remote sensing, genomics, bio-informatics and other technologies to make wheat more tolerant to heat and drought,â Kropff said.
The congress is the first major gathering of the wheat community since the 2015 International Wheat Conference in Sydney, Australia.
CGIAR and CIMMYT scientists will share the latest findings on:
State-of-the-art approaches for measuring traits to speed breeding for heat and drought tolerance
Breeding durum (pasta) wheat for traits for use in bread products
New sources of diversity â including ancient wheat relatives â to create aphid-resistant wheat and other improved varieties
DNA fingerprinting to help national partners identify gaps in improved variety adoption

Research shows that more than 60% of wheat varietal releases since 1994 were CGIAR-related.
Low- and middle-income countries are the primary focus and biggest beneficiaries of CGIAR wheat research, but high-income countries reap substantial rewards as well. In Canada, three-quarters of the wheat area is sown to CGIAR-related cultivars and in the United States almost 60% of the wheat area was sown to CGIAR-related varieties, according to the research.
WHEN
July 21-26, 2019
The opening ceremony and lectures will take place on
Monday, July 22, 2019 from 08:50 to 10:50 a.m.
CGIAR is a global research partnership for a food secure future dedicated to reducing poverty, enhancing food and nutrition security, and improving natural resources.
About the CGIAR Research Program on Wheat
Joining advanced science with field-level research and extension in lower- and middle-income countries, the Agri-Food Systems CGIAR Research Program on Wheat (WHEAT) works with public and private organizations worldwide to raise the productivity, production and affordable availability of wheat for 2.5 billion resource-poor producers and consumers who depend on the crop as a staple food.  WHEAT is led by the International Maize and Wheat Improvement Center (CIMMYT), with the International Center for Agricultural Research in the Dry Areas (ICARDA) as a primary research partner.  Funding for WHEAT comes from CGIAR and national governments, foundations, development banks and other public and private agencies, in particular the Australian Centre for International Agricultural Research (ACIAR), the UK Department for International Development (DFID) and the United States Agency for International Development (USAID). www.wheat.org

In just over a decade there will be around 8.5 billion people on earth, and almost 10 billion by 2050, according to the United Nations World Population Prospects 2019: Highlights.
The report said the newcomers will be concentrated in regions already facing grave food insecurity, rising temperatures, scarce water and erratic rainfall, such as sub-Saharan Africa and South Asia.
Even now, hungry persons worldwide exceed 850 million and an estimated 2 billion suffer micronutrient malnutrition, with costly health and social impacts.
By mid-century 7 of every 10 people will live in cities, according to United Nations data. With more mouths to feed and fewer farmers, food systems will be hard-pressed to grow and supply enough nutritious fare at affordable prices, while mitigating environmental damage.
Facing the challenges
As the examples below show, applied science and partnerships can help address these complex issues.
Decades of research and application by scientists, extension workers, machinery specialists, and farmers are refining and spreading practices that conserve soil and water resources, improve yields under hotter and drier conditions, and reduce the greenhouse gas emissions and pollution associated with maize and wheat farming in Africa, Asia, and Latin America.

The sustained support of funders and policymakers will help ensure that CIMMYT staff and partners are able to continue improving the livelihoods and food security of smallholder farmers and resource-poor consumers, as world population density increases.
Many maize farmers in sub-Saharan Africa grow old varieties that do not cope well under drought conditions. In the Oromia region of Ethiopia, farmer Sequare Regassa is improving her familyâs life by growing the newer drought-tolerant maize variety BH661. This hybrid was developed by the Ethiopian Institute of Agricultural Research (EIAR), using CIMMYT’s drought-tolerant inbred lines and one of EIAR’s lines. It was then officially released in 2011 by the EIAR as part of the Drought Tolerant Maize for Africa (DTMA) project, funded by the Bill & Melinda Gates Foundation and continued under the Stress Tolerant Maize for Africa (STMA) initiative.
âGetting a good maize harvest every year, even when it does not rain much, is important for my familyâs welfare,â said Regassa, a widow and mother of four, while feeding her granddaughter with white injera, a flat spongy bread made of white grain maize.
Since her husband died, Regassa has been the only breadwinner. Her children have grown up and established their own families, but the whole extended family makes a living from their eight-hectare farm in Guba Sayo district.

On the two hectares Regassa cultivates on her own, she rotates maize with pepper, sweet potato and anchote, a local tuber similar to cassava. Like many farming families in the region, she grows maize mainly for household food consumption, prepared as bread, soup, porridge and snacks.
Maize represents a third of cereals grown in Ethiopia. It is cheaper than wheat or teff â a traditional millet grain â and in poor households it can be mixed with teff to make the national staple, injera.
In April, as Regassa was preparing the land for the next cropping season, she wondered if rains would be good this year, as the rainy season was coming later than usual.
In this situation, choice of maize variety is crucial.
She used to plant a late-maturing hybrid released more than 25 years ago, BH660, the most popular variety in the early 2000s. However, this variety was not selected for drought tolerance. Ethiopian farmers face increasing drought risks which severely impact crop production, like the 2015 El Nino dry spell, leading to food insecurity and grain price volatility.
Under the DTMA project, maize breeders from CIMMYT and the Ethiopian Institute for Agricultural Research (EIAR) developed promising drought-tolerant hybrids which perform well under drought and normal conditions. After a series of evaluations, BH661 emerged as the best candidate with 10% better on-farm grain yield, higher biomass production, shorter maturity and 34% reduction in lodging, compared to BH660.
The resulting BH661 variety was released in 2011 for commercial cultivation in the mid-altitude sub-humid and transition highlands.
The year after, as farmers experienced drought, the Ethiopian extension service organized BH661 on-farm demonstrations, while breeders from CIMMYT and EIAR organized participatory varietal selection trials. Farmers were impressed by the outstanding performances of BH661 during these demos and trials and asked for seeds right away.
Seed companies had to quickly scale up certified seed production of BH661. The STMA project team assisted local seed companies in this process, through trainings and varietal trials. Companies decided to replace the old hybrid, BH660.

âIn addition to drought tolerance, BH661 is more resistant to important maize diseases like Turcicum leaf blight and grey leaf spot,â explained Dagne Wegary, a maize breeder at CIMMYT. âFor seed companies, there is no change in the way the hybrid is produced compared to BH660, but seed production of BH661 is much more cost-effective.â
EIARâs Bako National Maize Research Center supplied breeder seeds to several certified seed producers: Amhara Seed Enterprise (ASE), Bako Agricultural Research Center (BARC), Ethiopian Seed Enterprise (ESE), Oromia Seed Enterprise (OSE) and South Seed Enterprise (SSE). Certified seeds were then distributed through seed companies, agricultural offices and non-governmental organizations, with the technical and extension support of research centers.

From drought risk to clean water
After witnessing the performance of BH661 in a neighborâs field, Regassa asked advice from her local extension officer and decided to use it. She is now able to produce between 11-12 tons per hectare. She said her family life has changed forever since she started planting BH661.
With higher maize grain harvest, she is now able to better feed her chickens, sheep and cattle. She also sells some surplus at the local market and uses the income for her familyâs needs.

âIf farmers follow the recommended fertilizer application and other farming practices, BH661 performs much better than the old BH660 variety,â explained Regassa. âIf we experience a drought, it may be not that bad thanks to BH661âs drought tolerance.â
Regassa buys her improved seeds from the Bako Research Station, as well as from farmersâ cooperative unions. These cooperatives access seeds from seed companies and sell to farmers in their respective districts. âMany around me are interested in growing BH661. Sometimes we may get less seeds than requested as the demand exceeds the supply,â Regassa said.
She observed that maize prices have increased in recent years. A 100 kg bag of maize that used to sell for 200â400 Ethiopian birr (about $7â14) now sells for 600â700 Ethiopian birr (about $20â23). With the increased farmersâ wealth in her village, families were able to pay collectively for the installation of a communal water point to get easy access to clean water.
âLike womenâs role in society, no one can forget the role maize has in our community. It feeds us, it feeds our animals, and cobs are used as fuel. A successful maize harvest every year is a boon for our village,â Regassa concluded.
In a blog post and video released today, Bill Gates talks about the essential role the CGIAR system plays in feeding the world. He highlights the work the International Maize and Wheat Improvement Center (CIMMYT) is doing to develop and spread the use of drought-tolerant maize varieties. “One of the leading CGIAR research centers is CIMMYT, the International Maize and Wheat Improvement Center. They are working on improvements to maize that are more productive, that are resistant to drought and diseases. It’s a leading example of the amazing work the CGIAR system does to help smallholder farmers,” Gates says.
In 2018, Bill Gates launched a campaign about climate change, because he worried not enough people understood the dimensions of the problem. In a previous blog post, he reminded readers that not only the energy sector is concerned, but also âthe other 75%â â in particular agriculture and food systems. We need innovations to reduce our carbon footprint, Gates explained, but also to help the most vulnerable to cope with the effects of growing climate risks.
Rainfed smallholder farming families in sub-Saharan Africa are particularly at risk, as their livelihoods depend on unpredictable rainfall patterns. By the 2030s drought and rising temperatures could render 40% of the continentâs maize-growing area unsuitable for current varieties.
Drought-tolerant maize varieties could improve the climate resilience and the livelihoods of millions family farmers across Africa. The innovations offered by these varieties are affordable and scalable.

A team from Gates Notes came to drought-prone Machakos county in Kenya to visit farmers who are growing drought-tolerant hybrid maize. This variety, developed by the International Maize and Wheat Improvement Center (CIMMYT) and sold in the county by Dryland Seeds Limited under the SAWA brand, can yield up to 20% more than other drought-tolerant hybrids, explained the companyâs managing director, Ngila Kimotho.
Despite limited rainfall in the village of Vyulya, Veronica Nduku harvested well-filled maize cobs. Her neighbour, who grows a local variety, had a less successful harvest.
CIMMYT developed these varieties under the Drought Tolerant Maize for Africa (DTMA) initiative, a ten-year project which finished in 2015. This work is continuing under the Stress Tolerant Maize for Africa (STMA) initiative, which is developing maize varieties that cope well with drought and other climate stresses. So far 3.5 million farmers in 13 African countries are benefitting from stress-tolerant maize varieties.
