The International Maize and Wheat Improvement Center’s (CIMMYT) legacy of work with the Indian Centre for Agricultural Research (ICAR) has once again produced more successful collaborations this year. This solid partnership resulted in the release of new varieties poised to bring new, superior yielding, disease-resistant, high-quality wheat varieties suitable for different production environments to Indian farms.
The National Variety Release Committee announced the release of nine new varieties at the 60th All India Wheat and Barley Research Workers’ Virtual Meet on August 23–24, 2021, hosted by the Indian Institute of Wheat and Barley Research (IIWBR) of ICAR. Of the nine new varieties identified, five were selected by national partners from CIMMYT international trials and nurseries.
At the event, ICAR-IIWBR director Gyanendra Pratap (GP) Singh highlighted the impressive growth trajectory of India’s wheat production, estimated at 109.52 million tons of wheat harvested in 2021, a figure which was 86.53 million tons in 2015 and less than 60 million tons in 1991. Singh highlighted that this success is dependent upon the deployment of superior wheat varieties, bridging yield and information gaps, strengthened seed value chain, supportive government policies and, of course, farmer support to adopt new varieties and technologies.
The CIMMYT-derived varieties announced at the meeting include DBW296, DBW327, DBW332, HUW296 and JKW261. A few days earlier, variety PBW869 was released by the Punjab Agricultural University for growing in Punjab State under conservation agriculture practices.
“An innovative and powerful feature of ICAR-CIMMYT collaboration has been the introduction of long-term (10-month) rotational involvement of Indian young scientists in CIMMYTs breeding program at Mexico as well as in wheat blast screening in Bolivia,” said Arun Joshi, CIMMYT Regional Representative for Asia and Managing Director, Borlaug Institute for South Asia (BISA). “In this way, the breeding program of CIMMYT is an excellent example of joint breeding program with national institutions.”

Beyond expectations
In addition to these important new wheat varieties, some CIMMYT-derived wheat varieties that were released in recent years have now been deemed suitable for regions beyond their initial region of cultivation, showing wide adaptation and yield stability.
Wheat variety DBW222, released in 2020 for the northwestern plain zone, has now been deemed suitable for cultivation in the northeastern plain zone. Similarly, DBW187, which was initially released for the northeastern plain zone, and then for northwestern plain zone as well for early sowing, is now also extended for sowing in the central zone, together representing 25 million hectares of the 31 million hectares of wheat grown in India.
“Farmers prefer these types of varieties that give them flexibility during sowing time, and have high, stable yields, and disease resistance,” GP Singh said at the meeting.
A major achievement discussed at this year’s event was that three of the new varieties — DBW187, DBW303 and DBW222 — achieved record-high demand in Breeders Seed Indent, with first, second and seventh ranks, respectively. This is a reflection and indirect measure of popularity and demand for a variety. IIWBR’s innovative strategy to implement pre-release seed multiplication and create demand for seeds from new varieties has led to a faster turnover of improved varieties.
According to Ravi Singh, Distinguished Scientist and Head of Global Wheat Improvement at CIMMYT, the collaborators are “further expanding our partnership through the support from the Accelerating Genetic Gains in Maize and Wheat (AGG) and zinc-mainstreaming projects, to expand testing of larger sets of elite lines in targeted populations of environments of the four South Asian countries where various IIBWR-affiliated institutions shall expand testing in the 2021–22 crop season.” CIMMYT looks forward to continuing ongoing and new collaborations with the ICAR-IIWBR programs to deliver even faster genetic gain for yield and grain zinc levels in new varieties, he explained.
Speaking during the meeting Alison Bentley, Director of CIMMYT’s Global Wheat Program, highlighted the collaborative efforts underway as part of the AGG project to accelerate breeding progress. “Innovations and discoveries in breeding approaches are being rapidly made — with further investment needed — to quickly and equitably accumulate and deploy them to farmers,” she said.

With almost all CGIAR centers represented in Addis Ababa, Ethiopia is considered to be a hub for CGIAR research, and the organization has been a long-term partner to the Ethiopian government when it comes to agriculture. The partnership between CGIAR and the national partners is said to be an exemplary one, with CGIAR serving as the source of new technologies and innovations and national partners contextualizing these products within their own country context. This is believed to have brought impacts that serve the people on the ground.
A new report by CGIAR’s Standing Panel on Impact Assessment (SPIA) indicates that CGIAR innovations have reached between 4.1 and 11 million Ethiopian households. The report — which assesses 52 agricultural innovations and 26 claims of policy influence — documents the reach of CGIAR-related agricultural innovations across the core domains of CGIAR research activity: animal agriculture; crop germplasm improvement; natural resource management; and policy research.
The study compiles comprehensive information on the past two decades of CGIAR research activities in Ethiopia. Using information from interviews with CGIAR research leaders, scientists, government officials, published studies and project documents, this ‘stocktaking’ exercise was used to identify the innovations which are potentially disseminated at scale. The study also employs novel data collection protocols and methods like visual aid protocols for identification of natural resource management innovations or DNA fingerprinting for crop variety identification for barley, maize and sorghum.
The study results show that although many innovations are being adopted by some farmers, only a few are reaching large numbers of households. The three innovations with the largest reach are soil and water conservation practices, improved maize varieties and crossbred poultry. The study also found out that there are synergies between innovations where households adopt two or more. For instance, a household which adopts CGIAR maize varieties is likely to also adopt recommended natural resource management practices.
This, according to the study, is the result of different categories of CGIAR research efforts — natural resource management and policy, crop breeding and livestock research, respectively. The scaling of these innovations can also be linked to supportive government policies, which in turn have been influenced by policy research, as indicated in the report.

CIMMYT’s footprint
The International Maize and Wheat Improvement Center (CIMMYT) has maintained a presence in Ethiopia for over 30 years and is committed to supporting long-term agricultural development in the country. As part of this effort, CIMMYT has contributed to an increase in maize and wheat production in Ethiopia, working with national partners to test and release improved varieties.
The maize breeding program started in 1988 through CIMMYT and EIAR collaboration and in 1993 BH-660 was released — the first hybrid maize variety derived from CIMMYT germplasm. According to the report, specific maize traits were researched through the Drought Tolerant Maize for Africa (DTMA) and Drought Tolerant Maize for Africa Seed Scaling (DTMASS) projects, and since 2012 the Nutritious Maize for Ethiopia (NuME) project has aimed to develop varieties with higher protein content. Overall, 54 maize varieties have been released in Ethiopia since 1990, and 34 of these are thought to contain CIMMYT-related germplasm. It is also noted that, in the past 20 years ten drought-tolerant varieties and eight quality protein maize (QPM) varieties have been released.
In terms of geographical spread, the study highlights that improved maize varieties derived from CGIAR germplasm were highly adopted in the regions of Harar and Dire Dawa, which account for 81% of adopters overall. Adoption rates were also high in Tigray (79.3% of households), Amhara and the Southern Nations, Nationalities, and Peoples’ Region (63% of households), and Oromia (58.4% of households).
The other important crop in Ethiopia is wheat, which is grown by up to 4.8 million farmers in the country, according to the 2019 Central Statistics Authority (CSA) report. The SPIA document indicates that CGIAR innovations have played great role in the release and uptake of improved wheat varieties. The work of the CGIAR Research Program on Wheat (WHEAT), for instance, has resulted in the release of eight rust-resistant varieties derived from CIMMYT germplasm that are still under production. Of the 133 varieties released since 1974, CIMMYT and the International Center for Agricultural Research in the Dry Areas (ICARDA) played a role in developing at least 80.
The report concludes that agricultural research carried out by CGIAR scientists and their national partners generates many new ideas for innovations that might help address pressing policy concerns. CGIAR’s contribution to Ethiopia’s agricultural development is complex and wide-ranging, and while some aspects cannot be accurately captured by survey data, this new source of adoption and diffusion data helps identify the scale and scope of CGIAR’s reach in Ethiopia.
The Standing Panel on Impact Assessment (SPIA) is an external, impartial panel of experts in impact assessment appointed by the System Council and accountable to it. SPIA is responsible for providing rigorous, evidence-based, and independent strategic advice to the broader CGIAR System on efficient and effective impact assessment methods and practices, including those measuring impacts beyond contributions to science and economic performance, and on innovative ways to improve knowledge and capacity on how research contributes to development outcomes

Zambia’s vice-president has recently called to reduce maize dominance and increase crop and diet diversification in his country. The reality is that maize is and will remain a very important food crop for many eastern and southern African countries. Diet preferences and population growth mean that it is imperative to find solutions to increase maize production in these countries, but experts forecast 10 to 30% reduction in maize yields by 2030 in a business-as-usual scenario, with projected temperature increases of up to 2.7 degrees by 2050 and important drought risks.
Knowing the importance of maize for the food security of countries like Zambia, it is crucial to help maize farmers get better and more stable yields under erratic and challenging climate conditions.
To address this, the International Maize and Wheat Improvement Center (CIMMYT) and its partners have been developing hundreds of new maize varieties with good drought tolerance across sub-Saharan Africa. Stakeholders in the public research and African seed sectors have collaborated through the Drought Tolerant Maize for Africa (DTMA) project and the Stress Tolerant Maize for Africa (STMA) initiative to develop drought-tolerant seed that also incorporates other qualities, such as nutritional value and disease resistance.
A groundbreaking impact study six years ago demonstrated that drought-tolerant maize significantly reduced poverty and food insecurity, particularly in drought years.
A new study from CIMMYT and the Center for Development Research (ZEF) in the main maize growing areas of Zambia confirms that adopting drought-tolerant maize can increase yields by 38% and reduce the risks of crop failure by 36%.
Over three quarters of the rainfed farmers in the study experienced drought during the survey. These farming families of 6 or 7 people were cultivating 4 hectares of farmland on average, half planted with maize.
A balancing act between potential gains and climate risks
Drought-tolerant maize has a transformational effect. With maize farming becoming less risky, farmers are willing to invest more in fertilizer and other inputs and plant more maize.
However, taking the decision of adopting new farm technologies in a climate risky environment could be a daunting task. Farmers may potentially gain a lot but, at the same time, they must consider downside risks.
As Gertrude Banda, a lead farmer in eastern Zambia, put it, hybrid seeds have a cost and when you do not know whether rains will be enough “this is a gamble.” In addition to climate uncertainty, farmers worry about many other woes, like putting money aside for urgent healthcare, school fees, or cooking nutritious meals for the family.
Information is power
An additional hurdle to adoption is that farmers may not know all the options available to cope with climate risks. While 77% of Zambia households interviewed said they experienced drought in 2015, only 44% knew about drought-tolerant maize.
This inequal access to knowledge and better seeds, observed also in Uganda, slows adoption of drought-tolerant maize. There, 14% of farmers have adopted drought-tolerant maize varieties. If all farmers were aware of this technology, 8% more farmers would have adopted it.
Because farmers are used to paying for cheap open-pollinated varieties, they are only willing to pay half of the hybrid market price, even though new hybrids are performing very well. Awareness campaigns on the benefits of drought-tolerant maize could boost adoption among farmers.
According to the same study, the potential for scaling drought-tolerant maize could raise up to 47% if drought-tolerant varieties were made available at affordable prices at all agrodealers. Several approaches could be tested to increase access, such as input credit or subsidy schemes.
These impact studies were made possible through the support provided by the Bill & Melinda Gates Foundation and the US Agency for International Development (USAID), funders of the Stress Tolerant Maize for Africa (STMA) initiative.
