research: Durum wheat breeding

New heat-tolerant wheat varieties prove fruitful for Ethiopia’s irrigated lowlands

Written by Julian Bañuelos-Uribe on . Posted in Blogs.

Ethiopia is the largest wheat producer in Africa, accounting for around 65% of the total wheat production in sub-Saharan Africa. Despite the old tradition of rainfed wheat cultivation in the highlands, irrigated production in the dry, hot lowlands is a recent practice in the country.

In the irrigated lowlands of Afar and Oromia, situated along the Awash River Basin, CIMMYT and the Ethiopian Institute of Agricultural Research (EIAR) have been supporting small scale farming households to improve yields since 2021. The Adaptation, Demonstration and Piloting of Wheat Technologies for Irrigated Lowlands of Ethiopia (ADAPT-Wheat) project supports research centers to identify new technologies suitable for target planting areas through adaptation and development, which are then released to farmers. Funded by Germany’s Federal Ministry for Economic Development (BMZ) and Deutsche Gesellschaft fuer Internationale Zusammenarbeit (GIZ) GMBH, EIAR leads on implementation while CIMMYT provides technical support and coordination.

So far, several bread and durum wheat varieties and agronomic practices have been recommended for target areas through adaptation and demonstration. The seeds of adapted varieties have been multiplied and distributed to small scale farmers in a cluster approach on seed loan basis.

Cross-continent collaboration

The Werer Agricultural Research Center (WRC) run by EIAR has released two wheat varieties: one bread wheat line (EBW192905) and one durum wheat line (423613), both suitable for agroecology between 300-1700 meters above sea level.

Both varieties were selected from the CIMMYT wheat breeding program at its headquarters in Mexico. The new bread wheat variety exceeded the standard checks by 17% (Gaámabo and Kingbird) and 28% (Mangudo and Werer). 

The lines were trialed through multi-location testing in Afar and Oromia, with both lines displaying tolerance to biotic and abiotic stresses. Accelerated seed multiplication of these varieties is in progress using main and off seasons.

“These new varieties will diversify the number of adapted wheat varieties in the lowlands and increase yields under irrigation” said Geremew Awas, a CIMMYT research officer working for the ADAPT project in Ethiopia. Hailu Mengistu, EIAR wheat breeder at WRC, also indicated the need for fast seed delivery of climate resilient wheat varieties on farmers’ hands to realize genetic gain and increase income and food security of the households.

These new varieties will be provided with a local name by breeders to make it easy for farmers and other growers to identify them and will be introduced to farmers through demonstrations and field days. Eligible seed growers who are interested in producing and marketing the basic and certified seeds of these varieties can access early generation seeds from the WRC.

A new agreement between a leading Spanish seed company, Agrovegetal, and the international research center CIMMYT will help safeguard the regional availability of high-yielding, climate-resilient varieties of wheat, the region’s vital food staple.

The agreement was signed on 21 February 2024 at the Mexico headquarters of CIMMYT, a non-profit organization whose breeding contributions are present in half the maize and wheat varieties sown in low- and middle-income countries.

It comes at a time when severe drought threatens wheat crops in Southern Europe and North African nations such as Algeria, Morocco, and Tunisia and imports of wheat grain from traditional suppliers —Russia, the EU, Ukraine, and the US—are costly and constrained.

Since its formation in 1998 as a conglomerate of seed-producing cooperatives and a few industrial partners, Agrovegetal has been testing hundreds of CIMMYT breeding lines of bread and durum wheat (the latter used for pasta and couscous) and triticale (a wheat x rye hybrid) and returning high-quality data each year on the performance of this germplasm.

“The erratic rainfall, droughts, and crop disease patterns of Andalucía in southern Spain, where Agrovegetal tests the lines, are very much like those of North Africa, an important target region for CIMMYT genetics and agronomic solutions” said Bram Govaerts, director general of CIMMYT. “This new agreement, which guarantees the Agrovegetal-CIMMYT partnership through 2028, thus helps ensure CIMMYT’s capacity to offer outstanding, well adapted lines for the Mediterranean region, including North Africa’s national breeding programs, a great boon to farmers and consumers’ economies, food security, and nutrition.”

For its part, after several years of testing, Agrovegetal registers the most promising CIMMYT lines as improved varieties in Spain and markets their seed to members of its cooperatives.

“For us, the contributions of CIMMYT are invaluable,” said Ignacio Solis Martell, the company’s technical director. “Thanks to CIMMYT’s exceptional genetic material, Agrovegetal has become synonymous with resilience in Andalusia. Our varieties are renowned for their performance in the face of adversity, whether it be disease, drought, or other challenges.”

According to Govaerts, Agrovegetal offers an excellent model for burgeoning private seed enterprises in North Africa and elsewhere. “It shows how farmers, seed producers, and industry can join forces, skills, and resources to control seed, a critical factor in food production.”

Millers in Nigeria laud the release to farmers of co-developed, CIMMYT-derived wheat varieties

Written by Mike Listman on . Posted in Blogs.

Nigerian wheat scientists and millers recently recognized and thanked CIMMYT for its contributions to four new wheat varieties released to farmers, citing the varieties’ exceptional performance in field trials and farmers’ fields across national wheat-growing regions.

“The release of these four wheat varieties, uniquely tailored to suit our local conditions, has marked a significant milestone in enhancing food security and farmer livelihoods,” said Ahamed T. Abdullahi, agronomist for wheat value chains at the Flour Milling Association of Nigeria (FMAN), in a recent message to CIMMYT’s Global Wheat program. “The improved characteristics, such as higher yield potential, enhanced disease resistance, and adaptability to local climatic conditions, have significantly boosted wheat productivity. Moreover, the quality profiles of these varieties, as expressed in Nigeria, comply fully with the standards required by the local industry.”

Two of the varieties are bread wheat and yield up to 7 tons of grain per hectare, according to a recent Nigeria Tribune article. The other two are durum wheat, a species grown to make pasta and foods such as couscous and tabbouleh. One of those, given the name LACRIWHIT 14D in Nigeria, was from a CIMMYT wheat line selected for its novel genetic resistance to leaf rust and high-yield potential under irrigated conditions. It was also released in Mexico under the name CIRNO C2008 and is the country’s number-one durum wheat variety, according to Karim Ammar, a wheat breeder at CIMMYT.

“Aside from its high yield potential, it has considerable grain size and an aggressive grain fill that is expressed even under extreme heat,” explained Ammar. “These characteristics have certainly helped its identification as outstanding for Nigerian conditions.”

Writing on behalf of FMAN and the Lake Chad Research Institute (LCRI) of Nigeria’s Federal Ministry of Agriculture and Rural Development, Abdullahi said, “We deeply appreciate the expertise and support provided by CIMMYT throughout the development and release process. Your team’s technical guidance on the access to germplasm has played a crucial role in equipping our farmers and extension agents with the necessary skills and resources for successful wheat cultivation.”

Nigeria has a fast-growing population which, coupled with increasing per capita demand for wheat, has made increasing wheat production a national priority, according to Kevin Pixley, director of the Dryland Crops and Global Wheat programs at CIMMYT.

“Until recently, Nigeria produced only 2% of the wheat it consumes, but potential exists to double the current average yield and expand wheat production by perhaps 10-times its current area,” said Pixley. “New wheat varieties will be essential and must be grown using sustainable production practices that improve farmers’ livelihoods while safeguarding long-term food security and natural resources.”

Abdullahi said the release of the varieties demonstrated the power of collaborative research and highlighted the potential for future collaborations. “We look forward to continued collaborations and success in the pursuit of sustainable food systems.”

CIMMYT Ethiopia signs MoU with key private food processor to bolster durum wheat market

Written by mcallejas on . Posted in News.

CIMMYT Ethiopia signed a memorandum of understanding (MoU) in November 2023 with the Addis Ababa-based private food processing company Alvima Foods Complex Plc, in an effort to encourage durum wheat production among smallholder farmers and create market linkage in selected woredas of Oromia and Amhara regional states.

The MoU, which is part of CIMMYT Ethiopia’s overall durum wheat project aiming to reinvigorate durum wheat production in the country, was signed by Workneh Rikita, Alvima general manager, and Kindie Tesfaye, CIMMYT Ethiopia’s senior scientist.

CIMMYT Ethiopia signing a memorandum of understanding.

The MoU aims primarily to create market linkage between farmers and manufacturers, in a context of a sharp decrease of durum wheat production. “Prior to the 1980s, 80% of the wheat produced in Ethiopia was durum, but in 2016 our nationwide research on wheat showed that the durum wheat coverage was 5%, which stands in contrast to the country’s effort to industrialize the economy and substitute import goods with local produce”, said Kindie Tesfaye, CIMMYT durum wheat project leader. “We, as CIMMYT, want to encourage farmers to produce good quality durum wheat in quantity, and teach them about contract farming by creating market linkage with produce receivers like Alvima.”

“Cooperation, not business venture”

Established in 2011, Alvima Foods Complex initially centered its operations around importing and exporting agro-food products. In 2017, the company set up a pasta and flour processing factory and contracted 800 farmers to produce durum wheat. “At first, our objective was to produce premium quality pasta, unlike most processing companies in the country which produce pasta from hard wheat or mixed wheat,” said Workneh Rikita, Alvima’s general manager. In the absence of binding rules, the project failed and Alvima resigned to import durum wheat. “The law on contract farming was constituted recently and the difficulties to access foreign currency (therefore to import goods), which led us to turn our attention back to our initial project”, said Workneh Rikita.

Alvima Foods Complex general manager added that his company didn’t sign the agreement as a business venture but as an advantageous cooperation to learn from. He thanked CIMMYT for agreeing to work with his company and expressed his hopes for its success.

The current durum wheat market in Ethiopia is unpredictable as prices are set by the brokers, which heavily disadvantages the growers. The objective of the memorandum of understanding is to address such market challenges faced by farmers, affording them guaranteed market opportunities at a fair price.

As part of the agreement between Alvima Foods Complex and the durum wheat growers in target districts of the Amhara and Oromia regional states, CIMMYT will leverage on its expertise to help the farmers produce more and in good quality. Alvima will access the produce from farmers’ cooperatives directly, without the intervention of middlemen, to guarantee better incomes to producers. Moreover, CIMMYT is training farmers on use of climate information, accessing climate advisories, video-based production trainings, and crop disease management.

“If the farmers get the premium price for their produce, they will be encouraged to continue producing better wheat,” said Kindie Tesfaye. “We want the cooperation to be sustainable and to create direct links between farmers and local food processors (such as AVLIMA). The MoU will also benefit Ethiopia by decreasing imports of processed food items.”

A multilayered challenge to durum wheat production

Supported by the Bill and Melinda Gates Foundation, CIMMYT and Digital Green (an organization creating digital tools to assist farmers) have been conducting durum wheat improved varieties were insufficiently promoted; the seed was not made adequately accessible to farmers; productivity was perceived by farmers as being low; and market linkage was poor. These multilayered challenges led farmers to prioritize bread wheat varieties, according to Kindie Tesfaye.

In response, CIMMYT structured its support around three main pillars: the organization helps farmers access seeds together with Oromia’s Seed Enterprise, provides farmers with digital advisory services to improve their productivity, and works with the private and public sectors to upgrade market linkages, as with the memorandum of understanding signed with Alvima Foods Complex Plc.

 

CIMMYT researcher receives Heroes Award

Written by Julian Bañuelos-Uribe on . Posted in Press releases.

Maria Itria Ibba, a scientist at CIMMYT, received the inaugural Heroes Award from the Foundation for Innovation in Healthy Food. She received the award on October 29 at the ASA-CSSA-SSSA International Annual Meeting in St. Louis, Missouri, U.S.

Ibba, head of CIMMYT’s Wheat Chemistry and Quality Laboratory, received the honor in recognition of her outstanding leadership in launching the foundation’s Coalition for Grain Fiber initiative.

Together with her team at CIMMYT, Ibba works on improving the processing and nutritional quality of the bread and durum wheat lines derived from the CIMMYT spring wheat breeding programs. The research they conduct combines genetics and cereal chemistry, and one of the main focuses is to improve wheat grain dietary fiber. This effort begins with the development of efficient screening methods and the identification of germplasm with unique dietary fiber profiles.

The coalition seeks to improve the nutrition in staple foods without impacting their taste, mouthfeel or consumer price. It is simultaneously dedicated to establishing profit incentives for farmers and other food suppliers that enhance public health by delivering increased nutrient foods.

According to the coalition, improvements in the nutritional content of white and whole wheat flour may ultimately save thousands of lives and billions of healthcare U.S. dollars globally.

“Most people across the world do not consume enough dietary fiber, which is essential in the fight against various diseases,” says Ibba. “Increasing the dietary fiber content of a staple crop like wheat could have a significant positive impact on the health of wheat consumers. Our goal is to increase dietary fiber intake through the consumption of wheat products with greater fiber content.”

Plant breeders, food scientists, nutrition/health scientists and economists are partnering with the coalition to transform the food industry. They support non-GMO (not genetically modified organisms) approaches to increasing naturally occurring dietary fiber in grains.

Over 50 public and private-sector laboratory leaders in three countries and 23 U.S. states have engaged with the coalition, including from CIMMYT, Rothamsted Research, University of Nebraska, Lincoln, University of California, Davis, Cornell University and Bayer Crop Science.

The Nebraska Wheat Board provided support for the efforts of the foundation and the coalition.

“I feel humbled to have received the Heroes Award,” says Ibba. “I know that this award not only represents the work I have been doing, but also all the hard work that my team and my organization have been doing for several years.”

Country moving forward from wheat importer to self-sufficiency

Written by mcallejas on . Posted in Features.

Wheat is critical to millions of households in Pakistan as it serves a dual role as a foundational part of nutritional security and as an important part of the country’s economy. Pakistan’s goal to achieve self-sufficiency in wheat production is more attainable with the release of 31 wheat varieties since 2021.

These new seeds will help the country’s 9 million hectares of cultivated wheat fields become more productive, climate resilient, and disease resistant—a welcome development in a region where climate change scenarios threaten sustained wheat production.

The varieties, a selection of 30 bread wheat and 1 durum wheat, 26 of which developed from wheat germplasm provided by the International Maize and Wheat Improvement Center (CIMMYT) were selected after rigorous testing of international nurseries and field trials by partners across Pakistan. During this period, three bread wheat varieties were also developed from local breeding programs and two varieties (one each of durum and bread wheat) were also developed from the germplasm provided by the ICARDA. These efforts are moving Pakistan closer to its goal of improving food and nutrition security through wheat production, as outlined in the Pakistan Vision 2025 and Vision for Agriculture 2030.

Over multiple years and locations, the new varieties have exhibited a yield potential of 5-20% higher than current popular varieties for their respective regions and also feature excellent grain quality and attainable yields of over seven tons per hectare.

The new crop of varieties exhibit impressive resistance to leaf and yellow rusts, compatibility with wheat-rice and wheat-cotton farming systems, and resilience to stressors such as drought and heat.

Battling malnutrition

Malnutrition is rampant in Pakistan and the release of biofortified wheat varieties with higher zinc content will help mitigate its deleterious effects, especially among children and women. Akbar-2019, a biofortified variety released in 2019, is now cultivated on nearly 3.25 million hectares. Farmers like Akbar-2019 because of its 8-10% higher yields, rust resistance, and consumers report its good chapati (an unleavened flatbread) quality.

“It is gratifying seeing these new varieties resulting from collaborative projects between Pakistani wheat breeding programs and CIMMYT along with funding support from various donors (USAID, Bill & Melinda Gates Foundation, HarvestPlus, and FCDO) and the government of Pakistan,” said Ravi Singh, wheat expert and senior advisor.

Closing the yield gap between research fields and smallholder fields

Releasing a new variety is only the first step in changing the course of Pakistan’s wheat crop. The next step is delivering these new, quality seeds to markets quickly so farmers can realize the benefits as soon as possible.

Increasing evidence suggests the public sector cannot disseminate enough seeds alone; new policies must create an attractive environment for private sector partners and entrepreneurs.

“Pakistan has developed a fast-track seed multiplication program which engages both public and private sectors so the new varieties can be provided to seed companies for multiplication and provided to farmers in the shortest time,” said Javed Ahmad, Wheat Research Institute chief scientist.

Strengthening and diversifying seed production of newly released varieties can be done by decentralizing seed marketing and distribution systems and engaging both public and private sector actors. Marketing and training efforts need to be improved for women, who are mostly responsible for household level seed production and seed care.

A concerted effort to disseminate the improved seed is required, along with implementing conservation agriculture based sustainable intensification, to help Pakistan’s journey to self-sufficiency in wheat production.

Developing climate change resistant wheat

Written by Sarah McLaughlin on . Posted in In the media.

The International Maize and Wheat Improvement Center (CIMMYT) are at the forefront of dealing with the impact of climate change by developing wheat varieties with tolerance to heat and drought.

Wheat constitutes as much as 60% of daily calorie intake in developing countries. However, rising temperatures caused by climate change is reducing farmers’ yields.

Matthew Reynolds, Wheat Physiologist, and Maria Itria Ibba, Cereal Chemist, share how their work contributes towards securing food security and nutrition by breeding new wheat varieties.

The future of wheat

Written by Alfonso Cortés on . Posted in Videos.

CIMMYT’s experimental station in Obregón, a small city in Mexico’s state of Sonora, is considered a mecca for wheat research and breeding. In 1945, Norman Borlaug arrived as a geneticist for a special project between the Mexican government and the Rockefeller Foundation, to help local farmers with wheat production. After a few years, his strong bond with the community, students and interns was key to making a remarkable difference on wheat research that save millions from famine and won him the Nobel Peace Prize. A legacy that has lasted for many decades.

At Obregón, scientists have access to state-of-the-art field facilities and an ideal location, in the northern Yaqui Valley. The station’s dry climate and favorable temperature in winter is suitable to assess yield potential, while its hot summers are ideal to study wheat’s tolerance to different stressors.

Here, scientists and field workers work hard all year round to ensure the future of wheat. Varieties grown in all continents have CIMMYT and Sonoran DNA.

Can digital agricultural services boost Ethiopia’s durum wheat production?

Despite an increase in the total area used for growing wheat in Ethiopia, the share of durum wheat, the wheat used for pasta, has decreased substantially across the country. Smallholder farmers grow durum wheat on marginal lands for their own use but are not benefitting financially from cultivating the crop.

To understand factors contributing to low area coverage of durum wheat and identify opportunities for reinvigoration and improved marketing, the International Maize and Wheat Improvement Center (CIMMYT) hosted a workshop for stakeholders from the entire durum wheat value chain.

“New breeding technologies have great promise for expanding the area of durum wheat production,” said Moti Jaleta, agricultural economist at CIMMYT, “but this achievement remains primarily dependent on the market’s ability to purchase grains at a higher price to stimulate farmer adoption. The market in Ethiopia is not favoring durum wheat, so suppliers and extension workers must promote it very well.”

Rising consumption of durum wheat products such as pasta and macaroni is causing higher dependency on wheat imports. Reducing this reliance requires addressing the challenges facing Ethiopia’s durum wheat farmers in variety development and release, seed supply, crop management, level of productivity, market opportunities, and extension systems.

Kindie Tesfaye, scientist and crop modeler at CIMMYT, explained, “There is a need to improve the durum wheat seed system and extension service, enhance the development of new varieties with desired grain quality and create market linkages to meet the increasing durum wheat demand from the rapidly growing urban population and expanding agro-industrial parks.”

The potential of digital

As Ethiopia’s agricultural systems are highly dependent on rainfall, digital interventions can serve as key decision support tools to manage climate risk and bolster the adaptive capacity and productivity of smallholder farmers. CIMMYT collaborates with value chain-based digital agro-advisory services through the Digital Agricultural Advisory Services (DAAS) project, which runs multiple projects in Ethiopia to advance the use of digital tools in farming.

Taye Tadesse, director of crop research at the Ethiopian Institute of Agricultural Research, emphasized that the introduction of production technology should be participatory and customer-oriented to achieve the intended outcomes. Ensuring that technology is accessible is vital for strengthening the value chain system, he said.

Agreed actions from the workshop included focusing attention on the bodies responsible for the expansion of infrastructure and raising wheat farmers’ awareness of the value-adding tools available to them through training.

“We must ensure that farmers are the biggest decision-makers,” Tasfaye said.
