Nearly 3,000 smallholder wheat farmers throughout Pakistan will begin to sow seed of newer, high-yielding, disease-resistant wheat varieties and spread the seed among their peers in 2019, through a dynamic initiative that is revitalizing the contribution of science-based innovation for national agriculture.

Some 73 tons of seed of 15 improved wheat varieties recently went out to farmers in the provinces of Baluchistan, Gilgit Baltistan, Khyber Pakhtunkhwa, Punjab and Sindh, as part of the Agricultural Innovation Program (AIP), an initiative led by the International Maize and Wheat Improvement Center (CIMMYT) with funding from the US Agency for International Development (USAID).

“Our main goal is to help farmers replace outdated, disease-susceptible wheat varieties,” said Muhammad Imtiaz, CIMMYT scientist and country representative for Pakistan who leads the AIP. “Studies have shown that some Pakistan farmers grow the same variety for as long as 10 years, meaning they lose out on the superior qualities of newer varieties and their crops may fall victim to virulent, rapidly evolving wheat diseases.”

With support from CIMMYT and partners, participating farmers will not only enjoy as much as 20 percent higher harvests, but have agreed to produce and share surplus seed with neighbors, thus multiplying the new varieties’ reach and benefits, according to Imtiaz.

He said the new seed is part of AIP’s holistic focus on better cropping systems, including training farmers in improved management practices for wheat.

Wheat is Pakistan’s number-one food crop. Farmers there produce over 25 million tons of wheat each year — nearly as much as the entire annual wheat output of Africa or South America.

Annual per capita wheat consumption in Pakistan averages over 120 kilograms, among the highest in the world and providing over 60 percent of Pakistanis’ daily caloric intake.

The seed distributed includes varieties that offer enhanced levels of grain zinc content. The varieties were developed by CIMMYT in partnership with HarvestPlus, a CGIAR research program to study and deliver biofortified foods.

According to a 2011 nutrition survey, 39 percent of children in Pakistan and 48 percent of pregnant women suffer from zinc deficiency, leading to child stunting rates of more than 40 percent and high infant mortality.

“I am very excited to be part of Zincol-16 seed distribution, because its rich ingredients of nutrition will have a good impact on the health of my family,” said Munsif Ullah, a farmer from Swabi District, Khyber Pakhtunkhwa province.

Other seed distributed includes that of the Pakistan-13 variety for rainfed areas of Punjab, Shahkar-13 for the mountainous Gilgit-Baltistan, Ehsan-16 for rainfed areas in general, and the Umeed-14 and Zardana varieties for Baluchistan.

All varieties feature improved resistance to wheat rust diseases caused by fungi whose strains are mutating and spreading quickly in South Asia.

CIMMYT and partners are training farmers in quality seed production and setting up demonstration plots in farmers’ fields to create awareness about new varieties and production technologies, as well as collecting data to monitor the varieties’ performance.

They are also promoting resource-conserving practices such as balanced applications of fertilizer based on infrared sensor readings, ridge planting, and zero tillage. These innovations can save water, fertilizer, and land preparation costs, not to mention increasing yields.

“CIMMYT’s main focus in Pakistan is work with national wheat researchers to develop and spread better wheat production systems,” Imtiaz explained. “This includes improved farming practices and wheat lines that offer higher yields, disease resistance, and resilience under higher temperatures and dry conditions, as well as good end-use quality.”

CIMMYT’s partners in AIP include the National Rural Support Program (NRSP), the Lok Sanjh Foundation, the Village Friends Organization (VFO), the Aga Khan Rural Support Program (AKRSP), the National Agricultural Research Council (NARC) Wheat Program, the Wheat Research Institute (WRI) Faisalabad and Sakrand centers, AZRI-Umarkot, Kashmala Agro Seed Company, ARI-Quetta, BARDC-Quetta, and Model Farm Services Center, KP.

Gender norms – a set of cultural or societal rules or ideas on how each gender should behave – matters deeply on whether people adopt and benefit from innovations. Gender norms are also fluid, as they respond to changes in society, yet many of us fail to catch up with the changing norms.

Example: As farming becomes less and less profitable, men leave rural areas for cities in search of jobs. This leaves women in charge of farms, especially in subsistence farming, but many policymakers mistakenly believe that women’s roles are still confined to the house. This then becomes a barrier for women to benefit equally from agricultural innovations as men do, which negatively affects agricultural production in the household and community, more broadly.

A breakthrough CGIAR global comparative research initiative “GENNOVATE” has paved the way for developing gender-transformative interventions.

Among many resources it offers is a unique, in-depth gender knowledge base, established following five years of painstaking research – undertaken by 11 CGIAR centers, including ICARDA, and gender specialists across the globe. The study’s vast data and analyses have enabled researchers to move beyond smaller, unconnected studies that have largely defined gender research.

In order to address the question of how gender norms influence men, women, and youth to adopt innovation in agriculture and natural resource management, GENNOVATE has engaged 7,500 participants from 137 rural communities in 26 countries in Africa, Asia, and Latin America. The qualitative comparative study employs a framework based on the understanding that for innovation to be effective, women and men on the ground must exercise “agency” and be active participants in adopting new technology or practice.

The findings cast light on hidden norms within rural farming societies, as well as biases that influence decision making, technology access, and adoption within these societies and in rural development programming.

GENNOVATE also provides tools and resources to help the integration of gender sensitivities into agricultural research for development projects. These evidence-based inputs and recommendations can facilitate the development of less-biased, customized interventions that meets the specific needs of target populations. They can also ensure that this is done in an inclusive, responsible manner in tune with local norms.

This means scientists, practitioners, and policymakers can more easily incorporate gender into their work on climate-smart agriculture, conservation agriculture, mechanization, and farmer-training events, just to name a few. In short, it optimizes the chances of adoption of agricultural and environmental innovation.

ICARDA and GENNOVATE

ICARDA has contributed 10 case studies to GENNOVATE. Three case studies from Morocco focused on linking gender norms and agency with innovations in agriculture, such as drip irrigation, and improved wheat and chickpeas varieties. Uzbekistan’s four case studies linked gender norms and agency with improved wheat varieties. Three cases in India’s Rajasthan studied the link of gender norms and agency with improved barley varieties, contract barley farming, and improved goat breeds.

ICARDA also contributed to three of the six studies featured in The Journal of Gender, Agriculture, and Food Security’s special issue dedicated to GENNOVATE.

The paper “What drives capacity to innovate? Insights from women and men small-scale farmers in Africa, Asia, and Latin America” demonstrated that gender norms and personality attributes influence men’s and women’s ability to try out, adopt, and benefit from agricultural innovations, as well as their ability to make decisions around them – this is an area that has been largely underreported in the innovation literature.

“Gendered aspiration and occupations among rural youth in agriculture and beyond” shows that youth and gender issues are inextricably intertwined, and as a result, they cannot be understood in isolation from each other. The study also shows that deeply-ingrained gender norms often dissuade young women from pursuing agriculture-related occupation.

“Community typology framed by normative climate for agricultural innovation, empowerment, and poverty reduction” made a case that inclusive norms can lead to gender equality and agricultural innovation, deepening the capacity to make decisions that can lead to escape from poverty.

ICARDA’s contribution to GENNOVATE has been made possible with support from CGIAR Research Program on Wheat and CGIAR Research Program on Grain Legumes and Dryland Cereals.

A recent study by India and US scientists shows that when vulnerable young children in India consume foods with wheat-enriched zinc, the number of days they spend sick with pneumonia and vomiting significantly diminishes.

An estimated 26 percent of India’s population lacks adequate micronutrients in their diets. Developed through biofortification — the breeding of crop varieties whose grain features higher levels of micronutrients — high-zinc wheat can help address micronutrient deficiencies.

The results of the study, which took place over six months, confirm zinc-enhanced wheat’s potential to improve the diets and health of disadvantaged groups who consume wheat-based foods, but the authors conclude that longer-term studies are needed.

In partnership with HarvestPlus and partners in South Asia, the International Maize and Wheat Improvement Center (CIMMYT) has bred and fostered the release in the region of six zinc-enhanced varieties that are spreading among farmers and seed producers.

More than 70 agricultural professionals met in Islamabad, Pakistan, during September 4-5 to discuss agronomy and wheat activities under the Agricultural Innovation Program (AIP) for Pakistan. The event provided a platform for institutions involved in agronomy and the dissemination of agricultural technology and seed to share advances, discuss issues, and plan future undertakings.

“Crop productivity must be increased through research on innovative crop management techniques, varietal development and dissemination of better techniques and seed to farming communities,” said Dr. Yusuf Zafar, Chairman of PARC, addressing participants and touching upon a key theme of the event. He emphasized that precision agriculture, decision support systems, the use of drones, water productivity improvements and more widespread mechanization were on the horizon for Pakistani farmers, but that this would require active involvement of the public and private sectors.

Developments in zero tillage farming and ridge planting were highlighted in the two-day conference as conservation agriculture practices that are gaining traction in national wheat farming, according to Imtiaz Muhammad, CIMMYT representative and AIP project leader.

“In collaboration with a national network of 23 public and private partners, CIMMYT has reached more than 25,000 farmers through trainings on zero tillage, ridge planting, and direct seeded rice farming,” Imtiaz said, adding that support to farmers included nutrient management education the provision of seed planters. “These techniques are helping farmers to save water, avoid residue burning, and reduce their production costs.”

Collaboration with agricultural machinery manufacturers and other private sector actors is leading to local production of Zero Till Happy Seeders, which sow directly into unplowed fields and the residues of previous crops, according to Imtiaz. “Innovative approaches have also resulted in the production of 1,500 tons of wheat seed in 2018,” he explained.

Wheat seed production and farmers’ replacement of older varieties have progressed through local seed banks established by AIP in partnership with Pakistan’s National Rural Support Program (NRSP). Located in villages, the banks sell quality wheat seed for up to 12 percent less than local markets. “This is critical, because Pakistan’s wheat seed replacement is only 30 percent,” said Imtiaz, adding that there is a 50 percent gap between potential wheat yields and the national average yield for this crop.

The AIP will open more seed banks in remote areas of Pakistan, in conjunction with national partners. As well as producing and processing seed, the banks will provide farm machinery contract services and precision agriculture tools at subsidized rates.

Participants’ recommendations included adding straw spreaders to combine harvesters for rice, to facilitate the direct sowing of wheat after rice. They also suggested that agricultural service providers should help promote the direct seeding of rice and wheat with zero tillage implements. Participants observed that, in Baluchistan Province, support to farmers and service providers could increase the adoption of zero tillage for sowing wheat after rice and of precision land leveling, to improve irrigation efficiency and save water.

The AIP and partners will continue to promote water saving and nutrient management techniques, as well as building the capacity of farmers, national staff and agricultural service providers. Finally, those attending recommended that, for its second phase, AIP focus on the biofortification of wheat and rice, climate smart agriculture, decision support tools, women in farming, knowledge delivery, appropriate mechanization, nutrient management, weed management and water productivity.

AIP is the result of the combined efforts of the Pakistan Agriculture Research Council (PARC), the International Livestock Research Institute (ILRI), the International Center for Agricultural Research in the Dry Areas (ICARDA), the International Rice Research Institute (IRRI), the World Vegetable Center (AVRDC), the University of California at Davis, and the International Maize and Wheat Improvement Center (CIMMYT). It is funded by the United States Agency for International Development (USAID). With these national and international partners on board, AIP continues to improve Pakistan’s agricultural productivity and economy.

An international team of scientists applied genome-wide association analysis for the first time to study the genetics that underlie grain zinc concentrations in wheat, according to a report published in Nature Scientific Reports on 10 September.

Analyzing zinc concentrations in the grain of 330 bread wheat lines across diverse environments in India and Mexico, the researchers uncovered 39 new molecular markers associated with the trait, as well as 2 wheat genome segments that carry important genes for zinc uptake, translocation, and storage in wheat.

The findings promise greatly to ease development of wheat varieties with enhanced levels of zinc, a critical micronutrient lacking in the diets of many poor who depend on wheat-based food, according to Velu Govindan, wheat breeder at the International Maize and Wheat Improvement Center (CIMMYT) and first author of the new report.

“A collaboration among research centers in India, Australia, the USA and Mexico, this work will expedite breeding for higher zinc through use of ‘hotspot’ genome regions and molecular markers,” said Govindan. “It also advances efforts to make selection for grain zinc a standard feature of CIMMYT wheat breeding. Because varieties derived from CIMMYT breeding are grown on nearly half the world’s wheat lands, ‘mainstreaming’ high zinc in breeding programs could improve the micronutrient nutrition of millions.”

More than 17 percent of humans, largely across Asia and Africa, lack zinc in their diets, a factor responsible for the deaths of more than 400,000 young children each year.

Often used in human disease research, the genome-wide association approach was applied in this study to zero in on genome segments — known as quantitative trait loci (QTLs) — that carry genes of interest for wheat grain zinc content, according to Govindan.

“The advantages of the genome-wide association method over traditional QTL mapping include better coverage of alleles and the ability to include landraces, elite cultivars, and advanced breeding lines in the analysis,” he explained. “Our study fully opens the door for the expanded use of wheat progenitor species as sources of alleles for high grain zinc, and the outcomes helped us to identify other candidate genes from wheat, barley, Brachypodium grasses, and rice.”
Farmers in South Asia are growing six zinc-enhanced wheat varieties developed using CIMMYT breeding lines and released in recent years according to Ravi Singh, head of the CIMMYT Bread Wheat Improvement Program.

Financial support for this study was provided by HarvestPlus (www.HarvestPlus.org), a global alliance of agriculture and nutrition research institutions working to increase the micronutrient density of staple food crops through biofortification. The views expressed do not necessarily reflect those of HarvestPlus. It was also supported by CGIAR Funders, through the Research Program on Wheat and the Research Program on Agriculture for Nutrition and Health. Research partners in India and Pakistan greatly contributed to this study by conducting high-quality field trials.

In an excellent example of scientific collaboration spanning borders and generations, Mustapha El-Bouhssini, entomologist at the International Centre for Agricultural Research in the Dry Areas (ICARDA), screened wheat breeding lines from the International Maize and Wheat Improvement Center (CIMMYT) under glasshouse infestations of Russian wheat aphid (Diuraphis noxia), a major global pest of wheat. At least one of the lines, which were developed through crosses of wheat with related crop and grass species, showed high levels of resistance.

Scientists at CIMMYT began research on sources of RWA resistance for wheat in the early 1990s. Good sources of resistance from rye were accessed via wide crosses that combined major portions of both crop’s chromosomes, in collaborative work led by Adam J. Lukaszewski, University of California, Riverside.

“In our experiments, we did an initial screening with one replication and then a replicated test with a Pavon line and the check,” said El-Bouhssini.

Pavon is a semi-dwarf wheat variety developed by Sanjaya Rajaram, former CIMMYT wheat director and 2014 World Food Prize laureate. The version of Pavon referred to by El-Bouhssini had been crossed with rye by Lukaszewski and entered CIMMYT’s wheat genetic resource collections; the check was a popular high-yielding variety with no resistance to Russian wheat aphid.

Pavon had been used by Lukaszewski and colleagues as a model variety for wide crosses to transfer pest and disease resistance to wheat from its distant relatives. More recently Leonardo Crespo-Herrera, CIMMYT wheat breeder, pursued this research for his doctoral studies. It was he who provided a selection of wide-cross lines to El-Bouhssini.

“Resistance to pests in wheat is a valuable trait for farmers and the environment,” said Crespo-Herrera. “It can protect yield for farmers who lack access to other control methods. For those with access to insecticides, it can minimize their use and cost, as well as negative impacts on the environment and human health.”

A spatial mapping and ex ante study regarding the risk and potential spread in South Asia of wheat blast, a mysterious and deadly disease from the Americas that unexpectedly infected wheat in southwestern Bangladesh in 2016, identified 7 million hectares of wheat cropping areas in Bangladesh, India, and Pakistan whose agro-climatic conditions resemble those of the Bangladesh outbreak zone.

The study shows that, under a conservative scenario of 5-10% wheat blast production damage in a single season in those areas, wheat grain losses would amount to from 0.89 to 1.77 million tons, worth between $180 and $350 million. This would strain the region’s already fragile food security and force up wheat imports and prices, according to Khondoker Abdul Mottaleb, first author of the study.

“Climate change and related changes in weather patterns, together with continuing globalization, expose wheat crops to increased risks from pathogens that are sometimes transported over long distances,” said Mottaleb.

Foresight research at the International Maize and Wheat Improvement Center (CIMMYT) has focused on new diseases and pests that have emerged or spread in recent decades, threatening global food safety and security. For wheat these include Ug99 and other new strains of stem rust, the movement of stripe rust into new areas, and the sudden appearance in Bangladesh of wheat blast, which had previously been limited to South America.

“As early as 2011, CIMMYT researchers had warned that wheat blast could spread to new areas, including South Asia,” said Kai Sonder, who manages CIMMYT’s geographic information systems lab and was a co-author on the current study, referring to a 2011 note published by the American Pathological Society. “Now that forecast has come true.”

CIMMYT has played a pivotal role in global efforts to study and control blast, with funding from the Australian Center for International Agricultural Research (ACIAR), the CGIAR Research Program on Wheat (WHEAT), the Indian Council of Agriculture Research (ICAR), and the United States Agency for International Development (USAID).

This has included the release by Bangladesh of the first blast resistant, biofortified wheat variety in 2017, using a CIMMYT wheat line, and numerous training events on blast for South Asia researchers.

Fourteen young wheat researchers from South Asia recently attended a screening and surveillance course to address wheat blast, the mysterious and deadly disease whose surprise 2016 outbreak in southwestern Bangladesh devastated that region’s wheat crop, diminished farmers’ food security and livelihoods, and augured blast’s inexorable spread in South Asia.

Held from 24 February to 4 March 2018 at the Regional Agricultural Research Station (RARS), Jessore, as part of that facility’s precision phenotyping platform to develop resistant wheat varieties, the course emphasized hands-on practice for crucial and challenging aspects of disease control and resistance breeding, including scoring infections on plants and achieving optimal development of the disease on experimental wheat plots.

Cutting-edge approaches tested for the first time in South Asia included use of smartphone-attachable field microscopes together with artificial intelligence processing of images, allowing researchers identify blast lesions not visible to the naked eye.

“A disease like wheat blast, which respects no borders, can only be addressed through international collaboration and strengthening South Asia’s human and institutional capacities,” said Hans-Joachim Braun, director of the global wheat program of the International Maize and Wheat Improvement Center (CIMMYT), addressing participants and guests at the course opening ceremony. “Stable funding from CGIAR enabled CIMMYT and partners to react quickly to the 2016 outbreak, screening breeding lines in Bolivia and working with USDA-ARS, Fort Detrick, USA to identify resistance sources, resulting in the rapid release in 2017 of BARI Gom 33, Bangladesh’s first-ever blast resistant and zinc enriched wheat variety.”

Cooler and dryer weather during the 2017-18 wheat season has limited the incidence and severity of blast on Bangladesh’s latest wheat crop, but the disease remains a major threat for the country and its neighbors, according to P.K. Malaker, Chief Scientific Officer, Wheat Research Centre (WRC) of the Bangladesh Agricultural Research Institute (BARI).

“We need to raise awareness of the danger and the need for effective management, through training courses, workshops, and mass media campaigns,” said Malaker, speaking during the course.

The course was organized by CIMMYT, a Mexico-based organization that has collaborated with Bangladeshi research organizations for decades, with support from the Australian Center for International Agricultural Research (ACIAR), Indian Council of Agricultural Research (ICAR), CGIAR Research Program on Wheat (WHEAT), the United States Agency for International Development (USAID), and the Bangladesh Wheat and Maize Research Institute (BWMRI).

Speaking at the closing ceremony, N.C.D. Barma, WRC Director, thanked the participants and the management team and distributed certificates. “The training was very effective. BMWRI and CIMMYT have to work together to mitigate the threat of wheat blast in Bangladesh.”

Other participants included Jose Mauricio Fernandes, EMBRAPA-Passo Fundo, Brazil; Pawan Singh, CIMMYT wheat pathologist; T.P. Tiwari, Timothy J. Krupnik, and D.B. Pandit, CIMMYT-Bangladesh; Bahadur Mia, Bangladesh Agricultural University (BAU); and scientists from BMWRI and BARI, the Nepal Agricultural Research Council NARC, and Assam Agricultural University (AAU), India.
