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.

Bram Govaerts, renowned scientist and leader, has been appointed as CIMMYT’s Director General for the period 2023-2028 as of July 1, 2023, after holding the position on an interim basis for two years and steering the organization through the unprecedented global challenges of the pandemic and ongoing food insecurity.
Under Govaerts’ leadership, CIMMYT has expanded its research portfolio and strengthened its work in key regions. Govaerts has also started an effort to streamline internal processes and operations to speed up CIMMYT’s response capacity and impact across the world.
Govaerts holds a PhD in Bioscience Engineering – Soil Science, a master’s degree in Soil Conservation and Tropical Agriculture, and a bachelor’s degree in Bioscience Engineering, all from Katholieke Universiteit Leuven, Belgium. He has also received multiple awards during his career: the Development Cooperation Prize from the Belgian Federal Government in 2003, the Norman Borlaug Award for Field Research and Application in 2014, the Premio Tecnoagro, awarded by an organization of 2,500 Mexican farmers in 2018, and Fellow of The American Society of Agronomy (ASA). In addition to leading CIMMYT, Govaerts is an A.D. White Professor-at-Large at Cornell University.
“With Bram’s appointment, I am excited and confident about CIMMYT’s future,” said Margaret Bath, Chair of CIMMYT’s Board of Trustees. “We look forward to many great days ahead for CIMMYT staff across the globe, who lift smallholder farmers and their communities to achieve better and more sustainable livelihoods and to ensure that food security is delivered, and human potential maximized.”
Integrated management of organic and inorganic nitrogen sources in high- to low-yield cereal production could bring yearly savings in nitrogen fertilizer of over 1 million tons in India, some 90,000 tons in Ethiopia, and more than 20,000 tons in Malawi, according to a new scientific paper, “Spatially differentiated nitrogen supply is key in a global food-fertilizer price crisis.”
“Global policies and governments should prioritize nitrogen supplies to low-yield, low-fertility cropping systems, such as smallholder maize and rice farms in Malawi, which are representative of the highly N-deficient cereal systems relied upon by over 100 million people in sub-Saharan Africa,” said Sieglinde Snapp, director of the Sustainable Agrifood Systems Program at the International Maize and Wheat Improvement Center (CIMMYT) and first author of the paper. “Those farmers should also ramp up organic nitrogen inputs, such as manure and legume crops.”
In the intensive, high-yield cropping systems of India, farmers generally over-apply N fertilizer on 90% of the rice and wheat crops and more than half of maize crops. Less than half the nitrogen is taken up and used by the crops and the rest is lost into the environment, contaminating water, land, and the atmosphere. “Simply saving the excess fertilizer from over-fertilized areas and shifting it to low-application areas could increase global crop yields by 30%, with huge reductions in greenhouse gas emissions,” said Tek Sapkota, co-author of the paper and climate change leader at CIMMYT.
This study is based on evidence of achievable shifts in nitrogen management over 1-2 years, for a modest proportion of cropped area (10%). “We did not assess interventions with longer time horizons or large investment requirements such as precision agriculture, mechanization, or deep placement of fertilizer,” Snapp explained.
Snapp and her colleagues used evidence from the scientific literature to estimate N-fertilizer savings from the above interventions for maize, wheat, and rice cropping systems in India, Ethiopia, and Malawi. Integrated organic and inorganic nitrogen management was estimated by considering manure and legume N inputs along with N fertilizers. The effect of reallocating public subsidies to more cost-effective, high-N fertilizer was calculated as the extra nitrogen that could be made available through a lower unit cost of nitrogen.
Food production vs healthy environment?
According to Snapp, humanity is caught in a bind. Food crops grown using synthetic nitrogen fertilizer have fed expanding world populations since the 1960s, fertilizer use has increased nearly 10-fold since then, and significantly higher food demands lie ahead to mid-century. At the same time, poor use of N fertilizer is hurting the environment and, most recently, geopolitical conflicts have disrupted N fertilizer supplies and exposed the vulnerabilities of the global fuel-fertilizer-food nexus.
“In regions where cropping systems are highly deficient in nitrogen, investment is needed in policies and extension education to promote the use of organic nitrogen residues and legume crops,” Snapp said.
Extension agencies, she suggests, can extend their reach using digital tools and bi-directional communication approaches that engage local knowledge and farmers, including advisories regarding local soils and crop and fertilization requirements.

Reiterating the commitment to leading agriculture innovation across Africa, Bram Govaerts, director general of the International Maize and Wheat Improvement Center (CIMMYT), took part in the 8th Africa Agribusiness and Science Week (AASW8), June 5-8, 2023, in Durban, South Africa.
The theme of the AASW8 was linking science, innovation, and agribusiness for resilient food systems.
CGIAR System Board Chair Lindiwe Sibanda called for increased research and innovation to achieve an impact at scale and benefit African farmers at the opening ceremony.
Govaerts moderated a partner panel discussion regarding opportunities to strengthen the collaboration between One CGIAR and African research stakeholders.
Organizations represented on the panel included leaders from Technologies for African Agricultural Transformation, Total Landcare, Lupiya, Chitetezo Farmer Federation, and Green Sahel.
The African Development Bank, the African Union Commission, the Forum for Agricultural Research in Africa, and CGIAR also launched the Action Plan for the Abidjan II Communiqué that aims to build Africa’s resilience to future shocks by bolstering agricultural research and innovation systems to give farmers access to the science and technologies that they need to thrive.
“African countries must systematically review what is needed for the transformation of agrifood systems taking into consideration the present and future needs, and significantly increase investment in agricultural research and development,” said Govaerts.
Local and regional agribusiness is an essential industry playing a significant role in Africa’s prospects for economic growth and ensuring food security of its citizens. Still, challenges include regional harmonization of crop variety releases, surveillance of transboundary pests, and the growing threats of climate change.
“CIMMYT is dedicated to collaborating with local stakeholders to facilitate policies at the national, regional, and continental levels to promote proactive and eco-friendly management of transboundary plant health threats,” said Govaerts.
Several factors, including temperature, water deficit, and water access, have been identified as major causes in recent wheat yield variability worldwide. DSSAT wheat models showcase the impact of temperature, heat stress, water balance and drought stress in large wheat yield reductions due to climate change for Africa and South Asia, where food security is already a problem.

Former CIMMYT Director General Martin Kropff contributed a decade of his career to improving agri-food systems within CGIAR.
After ten years working at the International Maize and Wheat Improvement Center (CIMMYT) and CGIAR, Martin Kropff is retiring as Managing Director for Resilient Agri-food Systems at CGIAR. Learn more about his decision and his career in the video below.
At CIMMYT, Kropff led the development and implementation of a new Strategic Plan (2017-2022) for science with impact at scale. He also helped frame the One CIMMYT philosophy, which encourages a shared mission and vision through scientific excellence, impact through partnerships, and capacity development. He was a strong promoter of CIMMYT’s integrated and systems approach to multi-disciplinary science and, under his direction, CIMMYT became a more efficient, effective, and impactful organization.
Kropff also played a critical role in the development of One CGIAR, of which he was an early champion, by leading the organization’s reform in 2016, serving on the first System Management Board, and acting as co-chair of the advisory group on the CGIAR 2030 Research and Innovation Strategy. Throughout his tenure, Martin’s leadership, vision, and commitment to the organization’s mission have been instrumental in advancing CGIAR’s research for development agenda.
Margaret Bath, Chair of CIMMYT’s Board of Trustees, said, “We cannot thank Martin enough for his visionary efforts and for his strong contribution to the integration process that we have successfully achieved. We are grateful for his contributions and wish him well in his future endeavors.”
Honoring a legacy of innovative development in Zambia and looking forward to meeting the nation’s goals for food security, Bram Govaerts, director general of the International Maize and Wheat Improvement Center (CIMMYT), along with CGIAR Board Chair Lindiwe Sibanda, visited facilities and met with southern Africa collaborators of the Southern Africa AID-I Rapid Delivery Hub on June 2 and 3, 2023.
“CIMMYT’s work in Zambia and the region is geared to help national governments build resilience to climate change, diversify maize-based farming systems and improve productivity and production to address reduce hunger and poverty,” said Govaerts.
Southern Africa AID-I Rapid Delivery Hub aims to provide critical support to over 3 million farming households in Malawi, Tanzania and Zambia via targeted interventions for demand driven seed scaling, improved soil health and fertilizer use efficiency, and rapid delivery of critical agricultural advisory services deep into rural communities.
CIMMYT research and innovation supports Zambia’s medium-term goal of “Socio-Economic Transformation for Improved Livelihoods” and its 2030 Vision of becoming “A Prosperous Middle-Income Nation by 2030.”
Govaerts and Sibanda toured Afriseed’s factory in Lusaka and its wheat field trials in Ngwerere. They also attended a field demonstration of Purdue Improved Crop Storage bags in the nearby district of Chongwe organized by the Catholic Relief Services, a local partner promoting low-cost post-harvest technologies for small-scale farmers in Zambia.
The delegation visited private partner Zamseed, a company commercializing and releasing CIMMYT-bred, Fall Armyworm tolerant maize seeds.
Southern Africa AID-I Rapid Delivery Hub has enabled the release of nearly 10,000 metric tons of certified maize and legume seed, which have been harvested by Zambian seed companies and community-based seed organizations, directly benefiting a million semi-subsistence farmers.
Govaerts also hailed Zambia’s commitment to creating a transparent seed system. “Thanks to this conducive policy environment, Zambia is a major hub in sub-Saharan Africa for hybrid maize seed production and export in Africa.”
Besides Southern Africa AID-I Rapid Delivery Hub, CIMMYT and the Zambia Agricultural Research Institute have been collaborating for over two decades along with public and private partners in Zambia through different investments designed to create sustainable interventions that strengthen food systems and directly reach small-scale farmers.
The devastating disease wheat blast is a threat to crop production in many South Asian countries. In Bangladesh, it was first identified in seven southern and southwestern districts in 2016, and later spread to 27 others causing significant damage. The International Maize and Wheat Improvement Center (CIMMYT) is working with the Bangladesh Wheat and Maize Research Institute (BWMRI) and other national partners to conduct research and extension activities to mitigate the ongoing threat.
From March 1-10, 2023, a group of 46 wheat researchers, government extension agents, and policy makers from ten countries — Bangladesh, Brazil, China, Ethiopia, India, Japan, Mexico, Nepal, Sweden, and Zambia — gathered in Jashore, Bangladesh to learn about and exchange experiences regarding various wheat diseases, particularly wheat blast. Following the COVID-19 pandemic, this was the first in-person international wheat blast training held in Bangladesh. It focused on the practical application of key and tricky elements of disease surveillance and management strategies, such as resistance breeding and integrated disease management.
“This is an excellent training program,” said Shaikh Mohammad Bokhtiar, executive chairman of the Bangladesh Agriculture Research Council (BARC), during the opening session. “Participants will learn how to reduce the severity of the blast disease, develop and expand blast resistant varieties to farmers, increase production, and reduce imports.”
This sentiment was echoed by Golam Faruq, director general of BWMRI. “This program helps in the identification of blast-resistant lines from across the globe,” he said. “From this training, participants will learn to manage the devastating blast disease in their own countries and include these learnings into their national programs.”
Hands-on training
The training was divided into three sections: lectures by national and international scientists; laboratory and field experiment visits; and trips to farmers’ fields. Through the lecture series, participants learned about a variety of topics including disease identification, molecular detection, host-pathogen interaction, epidemiology and integrated disease management.
Hands-on activities were linked to working on the Precision Phenotyping Platform (PPP), which involves the characterization of more than 4,000 wheat germplasm and releasing several resistant varieties in countries vulnerable to wheat blast. Participants practiced taking heading notes, identifying field disease symptoms, tagging, and scoring disease. They conducted disease surveillance in farmers’ fields in Meherpur and Faridpur districts — both of which are extremely prone to wheat blast — observing the disease, collecting samples and GPS coordinates, and completing surveillance forms.
Participants learned how to use cutting-edge technology to recognize blast lesions in leaves using field microscopes. They went to a pre-installed spore trapping system in a farmer’s field to learn about the equipment and steps for collecting spore samples, observing them under a compound microscope, and counting spores. They also visited the certified seed production fields of Shawdesh Seed, a local company which has played an important role in promoting wheat blast resistant varieties BARI Gom 33 and BWMRI Gom 3 regionally, and Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU) in Gazipur to see current wheat blast research in action.
Blast-resistance in Bangladesh
“I am so happy to see the excellent infrastructure and work ethics of staff that has made possible good science and impactful research come out of the PPP,” said Aakash Chawade, associate professor in Plant Breeding at the Swedish University of Agricultural Sciences. “Rapid development of blast-resistant varieties and their dissemination will help Bangladesh mitigate the effects of wheat blast, not only inside the country but by supporting neighboring ones as well.”
“Besides the biotic and abiotic challenges faced in wheat production, climate change and the Russia-Ukraine crisis are further creating limitations to wheat production and marketing,” said Pawan Kumar Singh, head of Wheat Pathology at CIMMYT and lead organizer of the training. “Due to the development of blast-resistant wheat varieties and its commercial production under integrated disease management practices, the domestic production of wheat in Bangladesh has increased and there is increased interest from farmers in wheat.”
Dave Hodson, a principal scientist at CIMMYT and one of the training’s resource speakers, added: “This is a remarkable success that researchers developed two blast resistant varieties in Bangladesh urgently. It was only achievable because of the correct measures taken by the researchers and support of Government policies.”
However, there are still some barriers to widespread adoption of these varieties. As such, in parallel to other activities, a team from Bangladesh Agricultural University (BAU) joined the field trip to meet local farmers and conduct research into the socio-economic factors influencing the adoption and scaling of relevant wheat varieties.
