Indian scientists visit Türkiye for soil and root health training program

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

Soil is the foundation of agriculture, and healthy soil is critical to the entire ecosystem. However, soil health is under threat today as many factors make soil unhealthy, leading to significant losses in farming. CIMMYT in India has been addressing these issues in partnership with national and international institutions, while CIMMYT’s SBP program in Türkiye aims to deliver high-yielding wheat germplasm that is resistant to SBP and supports the International Soil-Borne Pathogens Research & Development Center (ISBPRDC) of Türkiye. It also facilitates knowledge exchange and technology transfer to support joint research and development activities to improve soil health.

On arrival, the group of scientists and professors from Bihar was welcomed by Metin Türker, director general of Agricultural Research and Policies (TAGEM). Talking about the intricate nexus of agriculture, climate, and technology, Türker emphasized varietal developments to irrigation advancements and engaged in lively discussions with the group, fueled by a shared vision for agricultural sustainability.

Led by Abdelfattah A. Dababat, CIMMYT country representative in Türkiye and the leader of the SBD program, the scientists and professors from India ventured into the heart of research institutions, immersing themselves in the latest innovations in wheat improvement and plant pathology. Their journey took them from Ankara to Eskisehir and ended at the Abant Izzet Baysal University, Bolu, where they were greeted by passionate experts eager to share their knowledge. Bonds were forged amid lectures and laboratory demonstrations, and ideas ignited, paving the way for future collaborations.

Visit to Ankara Province

The participants visited the Field Crops Central Research Institute and were introduced to the TAGEM Seed Gene Bank and Herbarium. Participants were acquainted with seed processing and preservation methods with live demonstrations. Following that, participants visited the Plant Protection Central Research Institute in Ankara, where its Director Ayse Ozdem gave an overview of the institute’s mandates and research work. Participants had the opportunity to explore the plant pathology laboratory and learn about major crop diseases in Türkiye and their control measures.

Participants later visited winter wheat trial sites at the research station in Haymana, a district of Ankara province. The group then interacted with Mesut Keser, ICARDA’s wheat breeder who specializes in winter and facultative wheat while working on the International Winter Wheat Improvement Program (IWWIP). This was followed by a visit to the pathology field experiments, a breeder seed production area, and an experimental trial for evaluating Syngenta TYMIRIUM® technology at the research station.

Visit to TZARI in Eskisehir

Scientists also had a chance to visit the Transitional Zone Agricultural Research Institute located in the Central Anatolian Plateau of Türkiye. The institute’s director Sabri Cakir welcomed the participants and briefed them about the ongoing research activities of the institute and its relevance to agriculture in Türkiye. Savas Belen gave a general overview of the institute and the breeding program, while Abdullah Tane Kilinc presented a glimpse of the activities of the Department of Plant Pathology. Professor Halil Toktay gave an overview of plant parasitic nematodes in wheat and potato, followed by Gül Erginbas Orakci who discussed the importance of managing soil-borne pathogens.

Beyhan Akin, wheat breeder at CIMMYT, gave a presentation on CIMMYT’s breeding activities in Türkiye, and Oğuz Önder presented fertilizer application on the quality of Bread Wheat and the importance of foliar fertilization in crops.

Thereafter, participants visited the plant pathology laboratory where Abdelfattah A. Dababat and Gül Erginbas-Orakci gave an overview of laboratory methods to study Cereal Cyst Nematodes and Root-Lesion Nematodes with live demonstrations. Innovative approaches to tackle the Plant-Parasitic Nematodes in agriculture were also discussed. In the agronomy laboratory, Oğuz Önder gave a live demonstration for estimating plant grain and biomass yield by optical sensor-based technologies. Participants also had the opportunity to explore the soil science laboratory and become familiar with state-of-the-art equipment used for soil nutrient analysis.

Visit to Bolu

The participants visited Abant Izzet Baysal University, in Bolu, where the Rector Professor. Mustafa Alişarlı welcomed them. This was followed by presentations and discussions on burning issues in agriculture. Professor Senol Yildiz gave a presentation on soil health assessment and management. Professor Halil Kütük of the Department of Plant Protection gave a brief overview of the latest research advancement in biological control of major crop diseases. In continuation, Abdelfattah A. Dababat gave an overview of the cereal cyst nematode and their management. The discussion led to a brainstorming session on soil health management, soil-borne diseases, soil microbiome, and the challenges of using microorganisms for soil health improvements. The major challenges and opportunities for agriculture development under changing climate scenarios in India and Türkiye were also discussed.

The training course exposed participants to the latest research and technologies for soil and root health management to increase agricultural productivity and profitability immediately and into the future. During the entire visit, participants working in different fields (soil science, agronomy, plant breeding, and microbiology) interacted with Türkiye’s expert counterparts to discuss their work and share valuable research insights. Several topics and technologies relevant to global agriculture, like zero tillage, climate-resilient agriculture, precision input management, hidden hunger, and digital agriculture, were discussed. Participants also explored future opportunities for bilateral research collaborations between India and Türkiye.

Participants expressed their deepest gratitude to the CIMMYT team at Türkiye, led by Abdelfattah A. Dababat, for arranging an effective training program and for the support provided at every step. “Your careful planning and thoughtful execution have created an environment where learning flourishes and connections are made.

Special thanks were offered to the Government of Bihar for supporting the travel of scientists from India for this training program under the climate-resilient agriculture project in the state.

Roots of resilience: my journey as a Conservation Agriculture champion

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

I am Grace Malaicha, a proud native of the Zidyana Extension Planning Areas in Central Malawi, where my journey with Conservation Agriculture (CA) began. In 2005, I observed neighboring farmers practicing CA techniques on their land. Intrigued and inspired, I decided to embark on this path myself, joining the CA program initiated by CIMMYT and Total LandCare in 2006. I started practicing it on my demonstration plot and observed that yields were getting higher from the second year onwards.

My dedication to CA has changed not only myself but also influenced other members of my farming community. As a mother trial host farmer under the CGIAR Initiative: Diversification for resilient agribusiness ecosystems in East and Southern Africa today, I have been implementing different treatments, which include maize doubled-up legume system and improved drought-tolerant maize varieties planted under CA on flat land and comparing it to the traditional ridge tillage system that involves substantial soil movement.

But what does CA mean to me? It is more than just a set of principles that I apply like minimum soil disturbance, mulching, and crop rotation. CA reduces drudgery, secures yields, and maintains productivity in times of climate change. CA has changed my approach to farming, transforming my once conventional maize monocrop into a diverse maize-legume system. By intercropping with two crops, I have spread the risk of unanticipated crop failure, while incorporating groundnut, cowpeas, and pigeon pea into the mix, which are more drought tolerant. I increased the land area under CA and tried it on many other crops including different legumes as rotation or intercrops, birds-eye chili, vegetables, and cassava.

Over the years, I have witnessed firsthand the harsh realities of a changing climate in central Malawi, from intense heat to prolonged droughts and erratic rainfall patterns. This year, 2024, has even been worse due to the prolonged dry spells between January and February, and the erratic rainfall during this time. Despite these challenges, our CA plots have continued to thrive, showcasing the resilience and adaptability of climate-smart farming practices.

Recognizing the power of knowledge sharing and from the encouragement by CIMMYT and Total LandCare, I started to train fellow farmers, both locally and across borders. At first, I worked with women groups around my homestead and trained about 100 female farmers on the principles of CA. I was fortunate to be given the opportunity to train other farmers in other districts of Malawi. Since 2008, I have also trained farmers in eastern Zambia and from Mozambique where all farmers speak my language Chichewa. Farmers believe other farmers more and are now realizing the benefits of implementing CA in their own fields.

I enrolled to be a local trainer in CA within my community in 2016. My passion for teaching and catalyzing change has led to the adoption of CA by numerous farmers. I embrace my commitment to ongoing learning through carefully implementing these CA trials and playing an active role during awareness meetings.

My life had changed so much. I was speaking on the radio and television. In 2012, the Minister of Agriculture visited my plot, and I was asked to speak in front of a Parliamentary Committee about my experiences as a smallholder woman farmer in Malawi. I spoke about what women can do in agriculture and what changes I made on my land. From representing my country at high level meetings, each step has shaped me into a resilient and empowered woman.

However, my journey has not been without obstacles, including hardships in my personal relationship. In 2012, I made the decision to join my husband in South Africa where I took up menial jobs to earn a living, abandoning my plot back home. But my true passion lay in farming, and I decided to make the bold decision to come back home, leaving my husband and continue with farming. Through perseverance and determination, I have overcome these challenges, and I am now much stronger.

Today, I stand with pride in front of my CA plot, not only sustaining my family but also sending all my children to school. I now converted all my land to conservation agriculture, 3ha are under maize and 2ha under groundnuts. Beyond farming, I have investments in housing, claiming rentals in the nearby town of Salima to sustain my financial income and expand in farming.

I will continue on this path as I learned so much over the years and believe that CA may be the only climate-smart agriculture response in reach of smallholder farmers that everybody can apply, and I will continue to support others as a champion of CA.

With agricultural diversification, more is better

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

Over the last seventy years, intensively managed monocultures, focused on maximizing calorie production, have become a dominant approach to global food production. This trend toward simplification in agricultural systems has supported productivity gains but has very troubling consequences for the environment including nutrient pollution and biodiversity loss at a massive scale. Restoring diversity is essential to regaining ecological balance.

Monocultures are generally all the same, turning biologically-rich systems into chemical-intensive engineered ones nearly devoid of life forms other than those yielding a genetically identical commodity crop. Their guiding principle is producing food ingredients as cheaply as possible. Biologically diversified agricultural systems can take many forms. Their guiding principle is recapturing resilience and resource use efficiency while supplying balanced diets and viable livelihoods.

In recent years, there have been many efforts to biologically diversify farming systems. Increasing the number of species and the genetic diversity is associated with improved resilience and resource use efficiency.

A new paper published in Science consolidates evidence from across a wide range of diversification strategies, applied on five continents, to understand how they affect environmental and social outcomes. These strategies encompass many different interventions ranging from crop rotations and cover crops to livestock inclusion to use of compost, hedgerows, and contour farming.

The study shows that the likelihood of environmental and social benefits goes up when a greater number of diversification strategies are combined. Importantly, the environmental benefits of diversification were found to be greatest in very simplified landscapes with less than 20% in non-crop area.

It also found that applying multiple diversification strategies in tandem reduces tradeoffs. In other words, the path to agricultural win-wins leads to diversified working landscapes, not just diversification strategies on individual farms.

The push toward commodity monocultures has been baked into many agricultural policies, such as subsidies and trade deals, and into land tenure systems. The monoculture bias is also reinforced through pricing, payment, and other supply chain arrangements. Even research agendas have encouraged monoculture with the long-term emphasis on yield-focused breeding.

It’s time to dismantle the structural barriers that leave so many farmers just getting by “against the odds” and at the expense of functioning ecosystems.

A sense of belonging: fostering gender equality and social inclusion in agricultural research

Written by Sarah McLaughlin on . Posted in Features.

Efforts to improve gender equality and social inclusion are under the spotlight in many workplaces around the world. At CIMMYT, where values of Excellence, Integrity, and Teamwork guide the organization through its 2030 Strategy, commitment to shaping a more inclusive workplace is changing the face of scientific research.

In alignment with the CGIAR Gender, Diversity and Inclusion (GDI) Action Plan for 2023-2024 to achieve gender parity goals, CIMMYT has implemented multiple initiatives to make improvements across its workstreams and geographical locations.

“This is the start of a journey to harness and empower talent from across CIMMYT’s employee base,” said Director General, Bram Govaerts. “Starting with the actions outlined below, CIMMYT aims to become a leader in promoting gender equality and social inclusion in agricultural research and development.”

Empowering women

At CIMMYT, our commitment to gender equality is reflected in our global workforce. During the first half of 2023, women represented one in every three staff members. Across all roles, the current hiring rate for women is 43% in 2023 compared to 21% in 2020, with a particularly positive trend in regional offices, where the percentage has increased from 24% in 2021 to 43% in 2023. Annual improvements are also visible in the number of internationally recruited female staff, as 46% of these roles are filled by women in 2023, compared to 19% in 2022.

In our headquarters in Mexico, there is no major gender gap above 10%, even at the highest level, and 35-40% of employees are women. 50% of the members of the senior leadership team are women, with a significant number of women from diverse backgrounds forming part of our broader management structure. Progress is also visible in our regional offices. In Kenya and Türkiye, 43% and 40% of team members are women respectively, with both countries reaching the CGIAR target of 40/40/20 parity. For the first time, women represented at least 20% of employees in Bangladesh and Nepal in 2023.

However, we recognize there are still areas where CIMMYT must improve gender parity. While the overall gender balance continues to improve, the proportion of women working at CIMMYT globally rests at 32.5%, which is a statistic that can be increased. Gender gaps exceeding 10% can be observed in India and Nepal, where efforts are bridging gaps and forming environments where talent knows no gender.

Advancing equality by region

The impressive diversity of our workforce is one of our greatest strengths, and CIMMYT always seeks new ways to champion its people. As a global organization with presence in 88 countries, benefits are tailored to each region to target the specific needs of employees in each locality.

  • The creation of a Gratuity and Provident Trust Fund in Bangladesh, fostering gender equality by providing equal opportunities for financial stability and growth.
  • Standardized benefits in India, such as a uniform transport allowance and upgraded housing allowance that ensures fair financial benefits for all employees regardless of job grade.
  • Enhanced food coupons and savings funds for employees in Mexico, as well as an after-school program for the children of colleagues working at the headquarters.
  • Responding to economic challenges in Pakistan with a 20% general salary increase, a bonus of US $400, and the introduction of a gender-neutral transport allowance.
  • An increased allowance for children’s education in Zimbabwe.

In addition, Flexible Work Arrangements (FWA), parental leave, disability access improvements, and translation services showcase CIMMYT’s dedication to equality and inclusion.

Fulfilling careers for all

Investing in our people means ensuring that learning opportunities are equally accessible to all, empowering employees to reach their maximum capabilities. “We actively work to foster a culture and environment where all staff feel confident sharing their perspectives, their contributions are highly valued, and they see a path for growth within the organization,” said Deputy Director of Human Resources, Jean-Flavien Le Besque.

In 2023, 1,189 staff members participated in 431 training courses, with the number of participants increasing by nearly 23% in the same year. Additional e-learning opportunities available in both English and Spanish provide opportunities for professional development in health and safety, communications, personal efficiency, and critical thinking, all which aid staff with the development of valuable skills. These online courses supplement regular training on teamwork, hostile environment awareness, and diversity, equity, and inclusion.

The CIMMYT Academy also plays a significant role in training staff to be future leaders. In 2022, 52 students enrolled into the Academy; 52% of these students are women, underscoring CIMMYT’s commitment to developing everyone’s talent. Staff can also access a Tuition Grant scheme to pursue a higher-level degree.

Next steps

While these initiatives have strengthened gender equality and social inclusion at CIMMYT, further efforts are required to achieve true equity in all corners of the organization. These projects so far are just a glimpse into ongoing work to achieve the CGIAR GDI aims and will be built upon using employee feedback and specialist expertise.

“These successes are just the start of our pledge to ensure CIMMYT is inclusive and safe for all,” said Associate Scientist and Cropping Systems Agronomist, Mazvita Chiduwa. “We want to be an organization that is renowned not just for scientific excellence, but also for the way we champion all groups to reach the best of their ability, thrive in the workplace, and enjoy a positive work-life balance.”

Unanswered questions and unquestioned answers

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

Over the past few decades, Conservation Agriculture (CA) has moved from theory to practice for many farmers in southern Africa. CA is a system that involves minimum soil disturbance, crop residue retention, and crop diversification among other complimentary agricultural practices. One reason for its increasing popularity is its potential to mitigate threats from climate change while increasing yields.

However, there are limits to the adaptation of CA, especially for smallholder farmers. Challenges are both agronomic (e.g. lack of sufficient crop residues as mulch, weed control, pest and disease carryover through crop residues), socio-economic, and political (both locally and regionally).

A recent paper, Unanswered questions and unquestioned answers: the challenges of crop residue retention and weed control in Conservation Agriculture systems of southern Africa, published in the journal Renewable Agriculture and Food Systems in February 2024, led by CIMMYT and CGIAR scientists examines two specific challenges to more widespread CA adaptation: how to deal with trade-offs in using crop residue and finding alternatives to herbicides for weed control.

For crop residue, the two most prevalent actions are using leftover crop residue for soil cover or feeding it to livestock. Currently, many farmers allow livestock to graze on crop residue in the field, leading to overgrazing and insufficient ground cover. This tradeoff is further challenged by other multiple household uses of residues such as fuel and building material. The most common way to control weeds is the application of herbicides. However, inefficient and injudicious herbicide use poses a threat to human health and the environment, so the research team set out to identify potential alternatives to chemical weed control as the sole practices in CA systems.

“The answer to the question ‘how should farmers control weeds?’ has always been herbicides,” said lead author Christian Thierfelder, CIMMYT principal cropping systems agronomist. “But herbicides have many negative side effects, so we wanted to question that answer and examine other potential weed control methods.”

What to do with crop residue

Previous research from the region found that ungrazed areas had long-term positive effects on soil fertility and crop yields. However, it is common practice for many farmers in Malawi, Zambia, and Zimbabwe to allow open grazing after the harvest in their communities. Livestock are free to graze wherever they wander, which results in overgrazing.

“Open grazing systems help keep costs down but are very inefficient in terms of use of resources. It leads to bare fields with poor soil,” said Thierfelder.

While it is easy to suggest that regulations should be enacted to limit open grazing, it is difficult to implement and enforce such rules in practice. The authors found that enforcement is lacking in smaller villages because community members are often related, which makes punishment difficult, and there is an inherent conflict of interest among those responsible for enforcement.

Controlling weeds

Weeding challenges in CA systems have been addressed worldwide by simply using herbicides. However, chemical weeding is often not affordable and, sometimes, inaccessible to the smallholder farmers and environmentally unfriendly.

Using herbicides, though effective when properly applied, also requires a degree of specialized knowledge, and without basic training, this may be an unviable option as they may pose a risk to the health of the farmers. Thus, alternatives need to be identified to overcome this challenge.

Some alternatives include mechanical methods, involving the use of handheld tools or more sophisticated tools pulled by animals or engines. While this can be effective, there is the possibility of high initial investments, and intercropping (a tenet of CA) forces farmers to maneuver carefully between rows to avoid unintended damage of the intercrop.

Increasing crop competition is another potential weed control system. By increasing plant density, reducing crop row spacing, and integrating other crops through intercropping, the crop competes more successfully with the weeds for resources such as light, moisture, and nutrients. When the crop seed rate is increased, the density of the crops increases, providing more cover to intercept light, and reducing the amount of light reaching the weeds thereby controlling their proliferation.

A holistic approach

“What we learned is that many of the crop residue and weed challenges are part of broader complications that cannot be resolved without understanding the interactions among the current scientific recommendations, private incentives, social norms, institutions, and government policy,” said Thierfelder.

Continuing research into CA should aim to examine the social and institutional innovations needed to mainstream CA as well as strengthen and expand the research on weed control alternatives and focus on the science of communal grazing land management to enhance their productivity.

USAID team lauds PQR value chain process in Bangladesh

Written by dmedina on . Posted in News.

Daily Sun Report, Rangpur

Experts of a visiting team from the United States Agency for International Development (USAID) have lauded the premium quality rice (PQR) value chain process in northern Bangladesh.

They made the admiration while visiting the Bengal Auto Rice Mills at Pulhat in Dinajpur and exchanging views with its owner, PQR farmers, local service providers (LSP) and traders on PQR production, milling and marketing.

Dr. Zachary P. Stewart, Production Systems Specialist of the Center for Agriculture-Led Growth, Bureau for Resilience, Environment and Food Security of the USAID from Washington led the team during their three-day tour in Northern Bangladesh that ended on Saturday.

John Laborde and Muhammad Nuruzzaman from the USAID’s Bangladesh Mission, Program Director of Sustainable Agrifood Systems at CIMMYT in Mexico Dr. Sieglinde Snapp and CIMMYT Country representative for Bangladesh Dr. Timothy J. Krupnik accompanied by him.

The Cereal Systems Initiative for South Asia CSISA-III project, funded by USAID and implemented by the International Rice Research Institute (IRRI) and International Maize and Wheat Improvement Center (CIMMYT), has been actively engaged in expanding and enhancing PQR value chains since 2016 in the Khulna division and since 2019 in the Rangpur division in Bangladesh.

The team members visited the entire Auto Rice Mills to observe the process of milling, sorting and packaging of PQR rice.

Owner of Bengal Auto Rice Mills Mr. Zahangir Alam informed that previously he sourced BRRI dhan50 (Banglamoti) from the southern part of Bangladesh.

However, since establishing a connection with CSISA in 2019, he has been procuring 30 percent to 40 percent of the total annual demand for BRRI dhan50 for producing PQR from the CSISA-beneficiary PQR farmers’ groups and others locally.

He highlighted how farmers have benefited from direct paddy purchases from them and obtaining high-quality and admixture-free rice.

“With assistance from CSISA, I have successfully branded this variety using its original name (BRRI dhan50) since 2020,” Zahangir Alam added.

Lead farmer Md. Azad expressed the advantages they have experienced from cultivating BRRI dhan50 through CSISA and higher yield of the BRRI dhan50 variety compared to the BRRI dhan28.

He highlighted their affiliation with the Bengal Auto Rice Mills, which has enabled them to fetch prices 7-8 Bangladesh Taka (BDT) higher per kilogram of paddy than those for BRRI dhan28.

During the visit, Agronomist from Bangladesh Office of IRRI Dr. Sharif Ahmed provided an overview of the PQR initiatives conducted by CSISA.

He also facilitated the tour alongside Md. Alanuzzaman Kurishi, Hub Coordinator at CIMMYT’s Dinajpur Field Office and Abdullah Miajy, a Specialist in Agricultural Research and Development at IRRI’s Rangpur Hub.

Successful surveillance results in early first detection of Ug99 in South Asia

Written by dmedina on . Posted in In the media.

The detection of the Ug99 wheat stem rust strain TTKTT in Nepal showcases the effectiveness of CIMMYT-led global surveillance efforts. Identified early through diligent field surveys by Nepal’s NPPRC and NWRP and confirmed by Denmark’s GRRC, this proactive response helped prevent further spread. Despite no subsequent detections in South Asia, the case underlines the importance of ongoing surveillance and development of resistant wheat varieties, supported by international initiatives.

CIMMYT Global Wheat Program (GWP) scientists visited National Agricultural Research Systems (NARS) partners in Pakistan, Nepal, and India during February 2024. The key purpose was to review current approaches and explore new opportunities to enhance collaborative wheat improvement activities.

NARS partners described their current priorities and recent changes in their activities, while CIMMYT shared recent modernization efforts of its wheat breeding and highlighted opportunities to enhance collaborative wheat improvement. GWP representatives included Interim Wheat Director Kevin Pixley, and scientists Naeela Qureshi, Velu Govindan, Keith Gardner, Sridhar Bhavani, T.P. Tiwari, and Arun K Joshi.

Planning the future of South Asian wheat

In each country, CIMMYT and NARS leaders held a one-day meeting to review and plan their wheat improvement partnership, with attendance from 25-30 wheat scientists in each country. The sessions aimed to review and identify bottlenecks to the wheat impact pathway in each country, describe recent changes in the breeding programs of CIMMYT and NARS partners, and prioritize and agree updates to the NARS-CIMMYT wheat improvement collaborations.

NARS partners highlighted their wheat improvement programs through field visits to research stations. Visitors attended Wheat Research Institute (ARI), Faisalabad and National Agricultural Research Center (NARC), Islamabad in Pakistan; National Wheat Research Program (NWRP), Bhairahawa and National Plant Breeding & Genetics Research Center (NPBGRC), Khumaltar in Nepal; and Indian Institute of Wheat and Barley Research (IIWBR), Punjab Agricultural University (PAU), Borlaug Institute for South Asia (BISA), and the Indian Agricultural Research Institute (IARI) in India.

The GWP team also visited: Faisalabad Agricultural University, with a special focus on collaborative zinc biofortification work in Pakistan; farmers’ fields in Nepal to see participatory evaluations of elite wheat lines (candidates for release as new varieties) and to hear from farmers about challenges and expectations from improved varieties; and the Lumbini Seed Company to learn about the crucial role of seed companies, bottlenecks, and opportunities in the pathway from research to impact in farmers’ fields.

NARS scientists and directors in all three countries were enthusiastic about the opportunities for enhanced partnership to adopt some of the modernizing technologies that AGG has brought to CIMMYT. Partners are especially keen to –

  1. Receive earlier generation varieties, segregating breeding lines to empower them to select in their own environments.
  2. Model and explore strategies to shorten their breeding cycles.
  3. Apply quantitative genetics tools to better select parents for their crossing blocks.
  4. Adopt experimental designs that improve efficiency.
  5. Explore opportunities for co-implementing improvement programs through shared testing schemes, communities of practice (e.g. for quantitative genetics or use of exotic germplasm to address challenges from climate change), and more.

“The visit provided CIMMYT and NARS wheat scientists with the opportunity to exchange experiences and ideas, and to explore ways of enhancing collaborations that will strengthen our joint impact on wheat farmers and consumers,” said Pixley.

Following these visits, the Bangladesh Wheat and Maize Research Institute (BWMRI) soon reached out to CIMMYT to request a similar review and planning meeting, with a vision to modernize and strengthen their wheat improvement partnership.
