CIMMYT training courses play a critical role in helping international researchers meet national food security and resource conservation goals. By sharing knowledge to build communities of agricultural knowledge in less developed countries, CIMMYT empowers researchers to aid farmers. In turn, these farmers help ensure sustainable food security. In contrast to formal academic training in plant breeding and agronomy, CIMMYT training activities are hands-on and highly specialized. Trainees from Africa, Asia and Latin America benefit from the data assembled and handled in a global research program. Alumni of CIMMYT courses often become a significant force for agricultural change in their countries.
The project goal is to provide smallholder farmers with appropriate mechanization technologies that reduce drudgery during farm operations.
The objectives of the project are:
To promote small-scale mechanization through awareness and demand creation, and service provision of appropriate technologies
To create employment along the mechanization value chain.
The project sites are located in Amhara, Oromia, SNNP (Southern Nations, Nationalities and Peoples) and Tigray regions of Ethiopia.
The target beneficiaries of the project include smallholder farmers who use traditional methods of farming, the youth who can be employed in service provision activities along the mechanization value chain, service providers, and private sector companies involved in equipment manufacturing and importing.
Through the project, smallholder farmers access planting, harvesting, post-harvest processing (threshing and shelling), irrigation and transport services from service providers located in their communities. The project operates under the Africa-RISING program led by ILRI in Ethiopia.

The Transforming Smallholder Food Systems in the Eastern Gangetic Plains (Rupantar) project aims to define the processes and practices (technical options, scaling interventions, policy settings and implementation) that can be applied to achieve sustainable, efficient, diversified food systems at scale in the Eastern Gangetic Plains of Bangladesh, India and Nepal.
Home to 450 million people, this region has the world’s highest concentration of rural poverty and strong dependence on agriculture for food and livelihoods. Productivity remains low and diversification is limited due to poorly developed markets, sparse agricultural knowledge and service networks, inadequate development of available water resources, and low adoption of improved, sustainable production practices.
Rupantar builds on existing work and partnership networks to link research outputs and development goals through the demonstration of inclusive diversification pathways, definition of processes for scaling to the millions of smallholder farmers in the region, and generating a better understanding of the policies that support diversification.
Research objectives
Defining the processes and practices (technical options, scaling interventions, policy settings and implementation) that can be applied to achieve sustainable, efficient, diversified food systems at scale in the Eastern Gangetic Plains.
Understanding the context for diversification in the Eastern Gangetic Plains.
Defining and implementing diversification pathways using collaborative and inclusive approaches.
Deepening understanding of the trade-offs and synergies associated with diversification pathways.
Engaging and communicating with change-makers to ensure outputs are used and integrated into independent programs.
Project outcomes
Demonstrated pathways for equitable and sustainable diversified food systems in the EGP.
Improved evidence-based policies for planning and development programs that promote diversification.
Self-sustaining diversification pathways that are owned by local partners and promoted without ongoing project support.

Zhuang Qiaosheng passed away in Beijing on May 8, 2022, at the age of 105. He was the most celebrated wheat breeder in China and enjoyed a high reputation in the international community.
As a leader of Wheat Breeding Program at Chinese Academy of Agricultural Sciences (CAAS), Zhuang developed 20 high-yielding and disease-resistant winter wheat varieties from 1947 to 1995, with a total planting area of 28 million hectares in achieving notable yield increase.
Zhuang served as a member of the Board of Trustees of the International Maize and Wheat Improvement Center (CIMMYT) from 1984 to 1987. He made great contributions to the collaboration between CIMMYT and China, including the opening of the CIMMYT office in China and the establishment of a shuttle breeding project for improving scab resistance.

He did everything possible to enlarge CIMMYT activities in China before fully retiring in 2015.
He was a close friend to many CIMMYT staff, including the late distinguished scientist Sanjaya Rajaram. He also strongly recommended He Zhonghu, distinguished scientist and CIMMYT Country Representative for China, to work at CIMMYT as a postdoctoral fellow in 1990.
The CIMMYT community sends its deepest condolences to the Zhuang family.

On April 26â29, 2022, researchers from Nepal participated in a workshop on the use of MARPLE Diagnostics, the most advanced genetic testing methodology for strain-level diagnostics of the deadly wheat yellow rust fungus. Scientists from the International Maize and Wheat Improvement Center (CIMMYT) and the John Innes Centre trained 21 researchers from the Nepal Agricultural Research Council (NARC) and one from iDE. The workshop took place at NARC’s National Plant Pathology Research Centre in Khumaltar, outside the capital Kathmandu.
âThe need for new diagnostic technologies like MARPLE and the critical timing of the workshop was highlighted by the severe yellow rust outbreak observed this season in the western areas of Nepal,â commented Dave Hodson, Senior Scientist at CIMMYT and project co-lead. âHaving national capacity to detect the increasing threats from yellow rust using MARPLE will be an important tool to help combat wheat rusts in Nepalâ.
The yellow rust fungus can cause grain yield losses of 30â80 % to wheat, Nepalâs third most important food crop.
Current diagnostic methods for wheat rust used in Nepal are slow, typically taking months between collecting the sample and final strain identification. They are also costly and reliant on sending samples overseas to highly specialized labs for analysis.
MARPLE (Mobile and Real-time PLant disEase) Diagnostics is the first method to place strain-level genetic diagnostics capability directly into the hands of Nepali researchers, generating data in-country in near-real time, for immediate integration into early warning systems and disease management decisions.
âThis is a fantastic opportunity to bring the latest innovations in plant disease diagnostics for the wheat rust pathogens to where they are needed most, in the hands of researchers in the field working tirelessly to combat these devastating diseases,â commented Diane Saunders, Group Leader at the John Innes Centre and project co-lead.

Suraj Baidya senior scientist and chief of the National Plant Pathology Research Centre at NARC noted the worrying recent geographical expansion of yellow rust in Nepal. âDue to global warming, yellow rust has now moved into the plain and river basin area likely due to evolution of heat tolerant pathotypes. MARPLE Diagnostics now gives us the rapid diagnostics needed to help identify and manage these changes in the rust pathogen population diversity,â he said.
The highly innovative MARPLE Diagnostics approach uses the hand-held MinION nanopore sequencer, built by Oxford Nanopore, to generate genetic data to type strains of the yellow rust fungus directly from field samples.
Beyond MARPLE Diagnostics, Saunders noted that âthe workshop has also opened up exciting new possibilities for researchers in Nepal, by providing local genome-sequencing capacity that is currently absent.â

Whatâs next for MARPLE Diagnostics in Nepal?
Following the successful workshop, Nepali researchers will be supported by CIMMYT and the John Innes Centre to undertake MARPLE Diagnostics on field samples collected by NARC. âThe current plan includes monitoring of yellow rust on the summer wheat crop planted at high hill areas and then early sampling in the 2022/23 wheat season,â Hodson noted.
âWe were struck by the enthusiasm and dedication of our colleagues to embrace the potential offered by MARPLE Diagnostics. Looking forward, we are excited to continue working with our Nepali colleagues towards our united goal of embedding this methodology in their national surveillance program for wheat rusts,â Saunders remarked.
MARPLE Diagnostics is supported by the Feed the Future Innovation Lab for Current and Emerging Threats to Crops, funded by the United States Agency for International Development (USAID), the UK Biotechnology and Biological Sciences Research Council (BBSRC) Innovator of the Year Award, the CGIAR Big Data Platform Inspire Challenge, the Bill & Melinda Gates Foundation and the United Kingdomâs Foreign, Commonwealth and Development Office.
Collaboration between food security institutions and research organizations has contributed to improvements in global grain production that have benefitted millions of farmers around the world â and must continue today. This message was highlighted during a ceremony hosted by the International Maize and Wheat Improvement Center (CIMMYT) to recognize the legacy of World Food Laureate and former CIMMYT Wheat Program Director Sanjaya Rajaram.
The ceremony, held at the CIMMYT Experimental Station in Toluca, State of Mexico, officially dedicated the Station in honor of Sanjaya Rajaram, honoring his memory as an âenemy of world hungerâ and one of the scientists who has most contributed to global food security.
The Indian-born naturalized Mexican researcher, who was the third person from CIMMYT to receive the World Food Prize, was recognized for having developed more than 480 high-yielding and adaptable wheat varieties that have been planted on approximately 58 million hectares around the world.
“For this impressive achievement, which seems easy to summarize in one sentence, Raj became a giant of the âright to foodâ and one of the fiercest enemies of hunger in the world,” said CIMMYT Director General Bram Govaerts.
âBuilding on the work of Dr. Norman Borlaug, Dr. Sanjaya Rajaram was a driving force in making CIMMYT into the extraordinary institution that it is today,â said Claudia Sadoff, Managing Director, Research Delivery and Impact of CGIAR, a global research partnership of which CIMMYT is a member.
âThe challenges of today compel us to redouble our efforts to breed more resilient and more nutritious crops, as Dr. Sanjaya Rajaram did, Sadoff added. âThis ceremony reminds us that Dr Rajaramâs legacy and the ongoing efforts of CIMMYT and CGIAR scientists must answer that.â
Awards for international cooperation in food security
At the event, CIMMYT presented awards to the Secretary of Foreign Affairs of Mexico, Marcelo Ebrard CasaubĂłn, and of Secretary of Agriculture and Rural Development (SADER), VĂctor Villalobos ArĂĄmbula, for their promotion of food security and social inclusion in Mexico and Latin America.
The Secretary of Foreign Affairs of Mexico expressed his gratitude for the Norman E. Borlaug and reaffirmed his commitment to “work in the international arena as we have done, but now we will have to work harder, with greater intensity.”
The Secretary of Agriculture and Rural Development of Mexico, VĂctor Villalobos ArĂĄmbula, emphasized that Mexico, Latin America and CIMMYT play an important role in the struggle to improve the conditions of small-scale farmers and the resilience of agri-food systems, noting that more than 300,000 farmers grow maize, wheat and associated crops on over one million hectares in Mexico using sustainable technologies from the CIMMYT-led MasAgro project, now called Crops for Mexico.
âThroughout this administration,â he said, âwe have designed, implemented and refined, through collaboration between SADER and CIMMYT, sustainable development strategies with a systemic approach that facilitates the participation of producers in more integrated and efficient value chains both in Mexico and in other countries.â
India’s Ambassador to Mexico, Pankaj Sharma, highlighted that his nation owes a large part of its Green Revolution to the “Sonora” wheat variety, which was developed in Mexico, a country that is considered one of the cradles of agriculture at a global level, with arable land accounting for 15 percent of the total land dedicated to agriculture in the world.
Report on the results of the Crops for Mexico initiative
CIMMYTâs Wheat Germplasm Bank Curator and Genotyping Specialist Carolina Sansaloni presented highlighted impacts from Crops for Mexico, the main cooperative project between the Government of Mexico — through the Secretary of Agriculture and Rural Development — and CIMMYT, and a flagship initiative in the application of technologies in sustainable agriculture.
The project has been in operation for more than a decade in 28 states in Mexico, with the collaboration of more than 100 national and international partners and private and public sector agencies in 12 regions, offering research infrastructure and training development for sustainable agronomic practices, she explained.
She reported that the results of 40 platforms, 500 demonstration modules and two thousand extension areas have an impact on more than one million hectares and benefit 300,000 maize, wheat and bean producers, with the use of high-yield varieties.
Rosalinda Muñoz Tafolla, a maize farmer in Amacuzac, in the Mexican state of Morelos, explained that her drive to produce healthy food led her to participate in Crops for Mexico, where CIMMYT’s support and advice has enabled her to dramatically increase her farmâs productivity while protecting the soil and conserving natural resources.
She explained that with the conservation agriculture system she learned to improve soil conditions, planted a new maize variety, and was supported in marketing her harvest at a good price and selling 2,000 maize ears (mostly weighing 200 grams each).
A change in policy by the Nepalese government in February 2022 opens up space for private seed companies to be involved in seed variety development, evaluation and distribution to farmers.
In the traditional Indian society Madhulika Singh grew up in, girls choosing to study science, technology, engineering or mathematics (STEM) was as radical as choosing a life partner on their own.
“They say women hold up half the sky. I believe they should hold up as much and contribute equally in STEM too,” says Singh, now an agriculture specialist at the International Maize and Wheat Improvement Center (CIMMYT).
In her early teens she saw her mother, a school headmaster, comfortably navigate her career along with her domestic responsibilities without a sweat. She later saw a similar example in her sister-in-law. “I grew up thinking âthere is so much that a woman is capable of,â whether at home or her workplace,” Singh recalls.
This strong idea of women’s potential led her to pursue studies in science. “Many women before me, like my mother’s generation, were encouraged to take up [careers in] humanities â become a teacher, or pursue home management courses â to ensure a smooth transition once married,” Singh explains. She hoped this would change during her time and that following a career in STEM would be a matter of choice â not gender.
Singhâs goals and ambitions were very clear from the very beginning. In school, she was interested in biology, particularly plant studies and botany. Her inquisitive nature was reflected in her projects and presentations, scoring her high grades. She demonstrated a thorough understanding of plant physiology and her passion for the subject. The budding scientist always wanted to know more and to do more, which Singh feels resonates with her current research and publications.
A popular quote attributed to Mahatma Gandhi says âBe the change you want to see in the world.â When Singh chose to take up plant science in graduate school and then agriculture science for her doctorate, she became the change she had hoped to see in her home and society as a young girl. With the support from her family but a skeptical society, she went ahead and pursued a career in STEM, beginning her research on maize genotypes and conservation agriculture. In 2013 she joined CIMMYT as a physiologist.

Helping farmers transition to conservation agriculture
Singh currently works in her home state of Bihar for the Cereal Systems Initiative for South Asia (CSISA), led by CIMMYT. She is engaged with over ten thousand farmers from the states of Bihar and Uttar Pradesh, supporting the adoption of  conservation agriculture practices.
Farming is vital for the region, as nearly 70% of the population is engaged in agriculture and extension services. However, food and livelihoods are threatened by the small size of farms, low incomes, and comparatively low levels of agricultural mechanization, irrigation and productivity.
Singh and her colleagues have led the transition from traditional farming to sustainable intensification practices â like early wheat sowing, zero tillage and direct-seeded rice â which have helped smallholder farmers increase their yield potential substantially.
“We believe a project like CSISA, along with the government and partners, can help advance and support in realizing the full agriculture potential of these regions,” Singh explains.
Roots in the soil
Her grandparents were farmers. “To be able to care for the land that provided you nourishment and a living was always admired upon,” she says. As a crop scientist, Singh’s family acknowledges her work as an extension of the services her grandparents practiced.
Sustained by this motivation and encouragement, Singh feels reassured of her role: joining other scientists, partners and farmers to make agriculture sustainable and our communities food-secure.
âThe fact that the data we generate from our experiments serve as building blocks in the generation of knowledge and help farmers optimize the cost of inputs and increase their productivity is fulfilling and enriching to me,” Singh expresses.
Apart from working to build the capacity of farmers and extension workers, Singh supports the implementation of field trials and community-based technology demonstrations. She also helps refine key agricultural innovations, through participatory testing, and optimizes cropping systems in the region.
Leading the way for for the next generation
A true representative of the STEM community, Singh is always learning and using her experience to give back to society. She has co-authored numerous books and contributed to journals, sharing her knowledge with others.
Other women leaders in STEM have inspired Singh in her professional life, including CIMMYTâs former deputy director general for research Marianne Banziger. Singh believes Banziger was trailblazing and that young girls today have many female role models in STEM that can serve as inspiration.
The change is already here and many more young women work in STEM, pursuing excellence in agriculture sciences, engineering and research studies contributing to as well as claiming âhalf the sky.”

Over the past several decades, maize breeders have made considerable strides in the development and deployment of new hybrids. These offer higher yields compared to older varieties and reduce the risks farmers face from the vagaries of a changing climate and emerging pest and disease threats. But, for small-scale farmers to adopt new, improved climate-resilient and stress-tolerant maize hybrids at scale, they must be first available, accessible and their benefits need to be widely understood and appreciated. This is where vibrant national seed industries potentially play an important role.
Prior to the 1990s, government agencies tended to play the lead role in hybrid production and distribution. Since then, expectations are that the private sector â in particular locally owned small-scale seed enterprises â produce maize hybrids and distribute them to farmers. When successful, local seed industries are able to produce quality new hybrids and effectively market them to farmers, such that newer hybrids replace older ones in agrodealer stores in relatively short periods of time. If small seed enterprises lack capacities or incentives to aggressively market new hybrids, then the gains made by breeding will not be realized in farmersâ fields. By monitoring seed sales, breeders at CIMMYT and elsewhere, as well as seed business owners, gain insights into smallholdersâ preferences and demands.
A recent publication in Food Security assesses the capacities of 22 small and medium-sized seed enterprises in Mexico to produce and market new maize hybrids. The study draws on the experience of the MasAgro project, a decade-long development whereby the International Maize and Wheat Improvement Center (CIMMYT), in partnership with Mexicoâs Department of Agriculture and Rural Development (SADER), engaged with dozens of locally owned seed businesses to expand their portfolio of maize hybrids.
The authors, led by CIMMYT senior economist Jason Donovan, highlight the critical role the MasAgro project played in reinvigorating the portfolios of maize seeds produced by small and medium-sized enterprises. MasAgro âfilled a gap that had long existed in publicly supported breeding programsâ by providing easy access to new cultivars, available to local seed companies without royalties or branding conditions, and without the need for seed certification. The enterprises, in turn, showed a remarkably high capacity to take up new seed technology, launching 129 commercial products between 2013 and 2017.
âWithout doubt the MasAgro project can be considered a success in terms of its ability to get new maize germplasm into the product portfolios of small seed companies throughout Mexico,â Donovan said.
The authors also delve into the challenges these maize enterprises faced as they looked to scale the new technologies in a competitive market that has long been dominated by multinational seed enterprises. They observed a lack of access to physical capital, which in turn evidenced a lack of financial capital or access to credit, as well as limited marketing know-how and capacity to integrate marketing innovations into their operations. While most maize enterprises identified the need to expand sales of new commercial products, âsigns of innovation in seed marketing were limitedâ and most of them relied heavily on sales to local and state governments.
According to Donovan, âThe MasAgro experience also shows that a strong focus on the demand side of formal seed systems is needed if breeding programs are to achieve greater impact in less time. This implies more attention to how farmers decide on which seed to purchase and how seed companies and seed retailers market seed to farmers. It also implies strong coordination between public sector to make building the local seed industry a national imperative.â
Beyond the Mexican context, the paperâs findings may be of particular interest to development organizations looking to supply local seed industries facing strong competition from regional and multinational companies. One example is the effort to support small seed businesses in Nepal, which face strong competition from larger Indian companies with long histories of engagement in Nepalese seed markets. There are also important lessons for policymakers in eastern and southern Africa, where strict controls over seed release and certification potentially lead to higher production costs and slower rates of introduction of new products by local maize seed companies.
New improved maize varieties may fall short in meeting the needs of women and the poorest of farmers â a concern that remains a focus of the International Maize and Wheat Improvement Center (CIMMYT) and the wider CGIAR.
Lower than expected adoption rates for some new maize varieties suggest that innovative strategies in breeding and seed delivery are likely needed. There is broad recognition of the need to get new germplasm from the CGIAR and its partners into the fields of more farmers in less time.
CIMMYT research on markets and social inclusion focuses on understanding two related dynamics: the unique preferences, needs and circumstances faced by women and the poorest farmers, and the implications these carry for how breeding programs and seed companies design and market new varieties.
Taking stock of knowledge and gaps in gender and maize breeding
Decades of research on maize preferences have sought to understand if and how menâs and womenâs preferences differ. However, existing data provides unclear guidance to maize breeders on gender-relevant traits to prioritize in product profile design. The evidence suggests a lack of meaningful differences in what men and women are looking for in maizeÂÂâyield, drought tolerance and early maturityâare high priorities almost across the board.
One reason for the similarity in preferences among women and men may relate to how we evaluate them, the authors argue. Preference studies that focus on evaluation of varietiesâ agronomic and productivity-related traits may overlook critical components of farmersâ variety assessment and seed choice, including their household and farming context. Ultimately, they say, we need to explore new approaches to evaluating farmer demand for seed, considering new questions instead of continuing to look for gender-based differences in preferences.
A first step in that direction is to figure out how demand for maize seed differs among farmers according to their needs, priorities and resource limitations. Gender is definitely a part of that equation, but thereâs much more to think about, like how maize fits into household food security and livelihoods, decision-making dynamics around maize production, and seed accessibility. New tools will be needed for understanding those and how decision-making around seed happens in real-world contexts.
Understanding how farmers make decisions on seed choice
The authors offer several practical suggestions for maize breeders and other researchers in this space:
First, explore tools that allow farmers to evaluate varieties in their household context. Large-scale farmer-managed on-farm trials have gained attention in the CGIAR as tools for more accurate assessment of farmer preferences. These approaches have several added advantages. They enable evaluation of variety performance under realistic management conditionsâincluding under management practices used disproportionately by women, such as intercropping, which is typically excluded from larger researcher-managed trials. These approaches also enable farmer evaluation of maize varieties not only in terms of in-field performance and yield at harvest stage, but in terms of grain quality after harvest. This is particularly important for social inclusion, given womenâs disproportionate attention to traits related to processing and consumption.
Second, move beyond gender-based preferences in evaluating seed demand. Gendered preferences matter, but they may not be the sole factor that determines a farmerâs choice of seed. We need to understand market segments for seed in relation to farmersâ aspirations, risk perceptions and tolerance, livelihood priorities, and household context. This also means exploring the intrahousehold gender dynamics of maize farming and seed choice to understand womenâs roles in decision-making in maize production, processing, and consumption.
Finally, consider questions related to maize seed systems more broadly. Are maize seed systems capable of delivering gender-responsive and gender-intentional varieties to women and men? What are the barriers to wider uptake of new varieties aside from variety suitability? Innovative marketing and delivery mechanisms may be critical to realizing gains from more gender-intentional breeding.
With the transition to the One CGIAR, sharing tools and lessons learned across crops will be increasingly important. Researchers in the CGIAR community have developed new tools for gender-responsive and gender-intentional breeding. This includes through the Gender and Breeding Initiative, which has published the G+ tools to support gendered market segmentation and gender-intentional product profile development.
While learning from one anotherâs experiences will prove essential during the transition, recognizing that the gender dynamics of maize production may be very different from sweet potato production will also be key. Here, the new Market Intelligence & Product Profiles initiative and SeEdQUAL initiative on seed systems will both create new spaces for exploring these issues across crops.

A newly published special issue in the journal Outlook on Agriculture features views and experiences on seed systems performance in Sub-Saharan Africa and options to drive faster uptake of new crop varieties. The contributions reflect the breadth of perspectives and expertise within CGIAR and beyond and make the case for the need for more demand-oriented variety development and seed delivery.
A seed system refers to the various actors, processes, and relationships that allow for the production, conservation, exchange and use of propagation materials for crops, trees, forages, livestock, and fish. For the International Maize and Wheat Improvement Center (CIMMYT), seed systems involve private seed companies, retailers, and government research agencies, among others, that are involved in the design, testing, production and distribution of high-yielding, climate-resilient, and pest- and disease-resistant maize hybrids.
âA well-functioning seed system is critical for ensuring that farmers have reliable access to the quality seeds that they want. It forms the critical link between breeders and the small-scale farmers responsible for much of the food production in Sub-Saharan Africa, Latin America and South Asia,â said CIMMYT Senior Economist Jason Donovan, who co-authored the introductory article.
âThe papers in this collection raise important issues which up to now have not received enough attention, to include the strategies, capacities and incentives of the private sector to invest in the distribution of new varieties. The topics discussed have implications for the One CGIAR in its ongoing efforts to develop a coherent and coordinated seed system research program that supports accelerated varietal uptake and turnover through effective seed delivery,â he added.
CIMMYT researchers contributed two papers, one which looks at the role of different types of seed producers and traders in shaping seed systems performance and another which proposes new directions for research on gender and formal maize seed systems. The special edition grew out of the CGIAR Community of Excellence for Seed Systems Development where CIMMYT led the discussion on seed value chains and private sector linkages.
One consensus among the authors is that a wider range of partnerships will be required to reenforce the potential of seed systems to delivery more new varieties to small-scale farmers in less time.
Two new students have graduated from the International Maize and Wheat Improvement Centerâs (CIMMYTâs) Soil-Borne Pathogens program. The two new graduates, Khawla Mehalaine and Salah-Eddine Laasli, were supervised by CIMMYT senior scientist Abdelfattah Dababat.
He leads the Soil-Borne Pathogens program, which focuses on identifying the main soil-borne pathogens associated with cereals and developing an integrated pest management approach to combat them. The research team is particularly interested in finding novel sources of resistance against these pathogens.
Over the last two decades, CIMMYT scientists leading the Soil-Borne Pathogens program have trained tens of students which constitute the next generation of top researchers on this topic. Through this program, CIMMYT has also organized workshops and courses in North Africa, including a symposium on cereal nematodes held in Agadir, Morocco, in 2017.
Since soil-borne pathogens are exacerbated by water stress conditions, researchers have identified the Central and West Asia and North Africa regions as priority areas, due to their vulnerability to drought.
On March 1, 2021, Syngenta, in collaboration with CIMMYT and other partners, led the first One Earth Soil and Root Health Forum, an event which examined the importance of root and soil health to food security, climate resilience and livelihoods. The event also created a community for action on root and soil health.

Nematodes in Algeria
Mehalaine holds an engineering degree in agronomy and a master’s degree in plant protection from the Higher National School of Agronomy (ENSA) in Algeria. She successfully defended her PhD dissertation âStudies of cereal cyst nematodes of the genus Heterodera in the regions of northern Algeriaâ in June 2021, graduating from ENSA with honors.
She studied the behavior of four durum wheat varieties against cereal cyst nematodes through field surveys, molecular identification at species levels, and by evaluating the yield components of these wheat varieties.
She was promoted by ENSA professor Hammach M. and supervised by Dababat from CIMMYT, and professors Mustafa Imren and GoÌksel OÌzer from Abant Izzet Baysal University in Turkey.
âCompleting my doctorate was a truly enriching experience and a challenging but rewarding journey,â Mehalaine said. âIt was a collective effort and I am extremely grateful to Dr Abdelfattah Dababat for sharing his scientific skills, for his patience and support, and for all the opportunities I was given to further my research. Thanks to him, I got to know the world of nematodes. Special thanks to CIMMYT for funding the molecular study part.â

Root-lesion nematode and crown rot fungi
Laasli graduated with an International Master of Agronomic and Environmental Nematology (IMANEMA) from Ghent University, in collaboration with CIMMYT, the National Institute of Agricultural Research in Morocco and the Faculty of Agriculture at Abant Izzet Baysal University in Turkey.
His master thesis, entitled âInteraction of Root-Lesion Nematode (Pratylenchus thornei) and Crown Rot fungi (Fusarium culmorum) associated with wheat resistance under simulated field conditions,â was promoted by Wim Bert, a professor at the University of Ghent, and Dababat. The project was also supervised by Imren and OÌzer.
Laasli evaluated the host status of 150 spring wheat lines to both P. thornei and F. culmorum, and estimated the damage caused by the disease complex involving both pathogens at different infection scenarios. He found several lines that possessed multiple resistance to both diseases tested â which could be powerful sources of resistance for breeding program worldwide.

For over a decade, the CGIAR Research Programs on Maize (MAIZE) and Wheat (WHEAT) have been at the forefront of research-for-development benefiting maize and wheat farmers in the Global South, especially those most vulnerable to the shocks of a changing climate.
From 2012 to 2021, MAIZE has focused on doubling maize productivity and increasing incomes and livelihood opportunities from sustainable maize-based farming systems. Through MAIZE, scientists released over 650 elite, high-yielding maize varieties stacked with climate adaptive, nutrition enhancing, and pest and disease resistant traits.
The WHEAT program has worked to improve sustainable production and incomes for wheat farmers, especially smallholders, through collaboration, cutting-edge science and field-level research. Jointly with partners, WHEAT scientists released 880 high-yielding, disease- and pest-resistant, climate-resilient and nutritious varieties in 59 countries over the life of the program.
To document and share this legacy, the MAIZE and WHEAT websites have been redesigned to highlight the accomplishments of the programs and to capture their impact across the five main CGIAR Impact Areas: nutrition, poverty, gender, climate and the environment.
We invite you to visit these visually rich, sites to view the global impact of MAIZE and WHEAT, and how this essential work will continue in the future.
CIMMYTâs relationship with Mexico is one of a kind: in addition to being the birthplace of the wheat innovations that led to the Green Revolution and the founding of CGIAR, Mexico is also where maize originated thousands of years ago, becoming an emblem of the countryâs economy and identity.
Honoring this longstanding connection and celebrating Mexicoâs key contribution to global wheat and maize production, Mexico City will host a photo exhibition from December 1, 2021, to January 15, 2022, in the Open Galleries Lateral, located on Paseo de la Reforma, one of cityâs most iconic promenades.
Titled âMaize and Wheat Research in Focus: Celebrating a Decade of Research for Sustainable Agricultural Development Under the CGIAR Research Programs on Maize and Wheat,â the exhibition illustrates the impact of MAIZE and WHEAT over the last ten years. The selection of photographs documents the challenges faced by maize and wheat smallholders in different regions, and showcases innovative interventions made by national and regional stakeholders worldwide.
From pathbreaking breeding research on climate-smart varieties to helping farming families raise their incomes, the photos â taken by CGIAR photographers before the COVID-19 pandemic â capture both the breadth of the challenges facing our global agri-food systems and the spirit of innovation and cooperation to meet them head on.
Donât miss the chance to visit the exhibition if you are in Mexico City!
