DHAKA, Bangladesh (CIMMYT) — As wheat farmers in Bangladesh struggle to recover from a 2016 outbreak of a mysterious disease called “wheat blast,” the country’s National Seed Board (NSB) released a new, high-yielding, blast-resistant wheat variety, according to a communication from the Wheat Research Centre (WRC) in Bangladesh.

Called “BARI Gom 33,” the variety was developed by WRC using a breeding line from the International Maize and Wheat Improvement Center (CIMMYT), a Mexico-based organization that has collaborated with Bangladeshi research organizations for decades, according to Naresh C. Deb Barma, Director of WRC, who said the variety had passed extensive field and laboratory testing. “Gom” means “wheat grain” in Bangla, the Bengali language used in Bangladesh.

“This represents an incredibly rapid response to blast, which struck in a surprise outbreak on 15,000 hectares of wheat in southwestern Bangladesh just last year, devastating the crop and greatly affecting farmers’ food security and livelihoods, not to mention their confidence in sowing wheat,” Barma said.

Caused by the fungus Magnaporthe oryzae pathotype triticum, wheat blast was first identified in Brazil in 1985 and has constrained wheat farming in South America for decades. Little is known about the genetics or interactions of the fungus with wheat or other hosts. Few resistant varieties have been released in Brazil, Bolivia and Paraguay, the countries most affected by wheat blast.

The Bangladesh outbreak was its first appearance in South Asia, a region where rice-wheat cropping rotations cover 13 million hectares and over a billion inhabitants eat wheat as main staple.

Many blast fungal strains are impervious to fungicides, according to Pawan Singh, a CIMMYT wheat pathologist. “The Bangladesh variant is still sensitive to fungicides, but this may not last forever, so we’re rushing to develop and spread new, blast-resistant wheat varieties for South Asia,” Singh explained.

The urgent global response to blast received a big boost in June from the Australian Centre for International Agricultural Research (ACIAR), which funded an initial four-year research project to breed blast resistant wheat varieties and the Indian Council of Agricultural Research (ICAR), which also provided grant to kick-start the work in South Asia. Led by CIMMYT, the initiative involves researchers from nearly a dozen institutions worldwide.

Chemical controls are costly and potentially harmful to human and environmental health, so protecting crops like wheat with inherent resistance is the smart alternative, but resistance must be genetically complex, combining several genes, to withstand new mutations of the pathogen over time.

Key partners in the new project are the agricultural research organizations of Bangladesh, including the Bangladesh Agricultural Research Institute (BARI), and the Instituto Nacional de Innovación Agropecuaria y Forestal in Bolivia, which will assist with large-scale field experiments to select wheat lines under artificial and natural infections of wheat blast.

Other partners include national and provincial research organizations in India, Nepal and Pakistan, as well as Kansas State University (KSU) and the U.S. Department of Agriculture-Agricultural Research Services (USDA-ARS). The U.S. Agency for International Agricultural Development (USAID) has also supported efforts to kick-start blast control measures, partnerships and upscaling the breeding, testing and seed multiplication of new, high-yielding, disease resistant varieties through its Feed the Future project.

BARI Gom 33 was tested for resistance to wheat blast in field trials in Bolivia and Bangladesh and in greenhouse tests by the USDA-ARS laboratory at Fort Detrick, Maryland. International partnerships are critical for a fast response to wheat blast, according to Hans-Joachim Braun, director of CIMMYT’s Global Wheat Program.

“Worldwide, we’re in the middle of efforts that include blast surveillance and forecasting, studies on the pathogen’s genetics and biology, integrated disease management and seed systems, as well as raising awareness about the disease and training for researchers, extension workers, and farmers,” said Braun.

With over 160 million people, Bangladesh is among the world’s most densely populated countries. Wheat is Bangladesh’s second most important staple food, after rice. The country grows more than 1.3 million tons each year but consumes 4.5 million tons, meaning that imports whose costs exceed $0.7 billion each year comprise more than two-thirds of domestic wheat grain use.

WRC will produce tons of breeder’s seed of BARI Gom 33 each year. This will be used by the Bangladesh Agricultural Development Corporation (BADC) and diverse non-governmental organizations and private companies to produce certified seed for farmers.

“This year WRC will provide seed to BADC for multiplication and the Department of Agricultural Extension will establish on-farm demonstrations of the new variety in blast prone districts during 2017-18,” said Barma.

As an added benefit for the nutrition of wheat consuming households, BARI Gom 33 grain features 30 percent higher levels of zinc than conventional wheat. Zinc is a critical micronutrient missing in the diets of many of the poor throughout South Asia and whose lack particularly harms the health of pregnant women and children under 5 years old.

With funding from HarvestPlus and the CGIAR Research Program on Agriculture for Nutrition, CIMMYT is leading global efforts to breed biofortified wheat with better agronomic and nutritional quality traits. The wheat line used in BARI Gom 33 was developed at CIMMYT, Mexico, through traditional cross-breeding and shared with Bangladesh and other cooperators in South Asia through the Center’s International Wheat Improvement Network, which celebrates 50 years in 2018.

Stable window 1 and 2 (W1W2) funding from CGIAR enabled CIMMYT and partners to react quickly and screen breeding lines in Bolivia, as well as working with KSU to identify sources of wheat blast resistance. The following W1 funders have made wheat blast resistance breeding possible: Australia, the Bill & Melinda Gates Foundation, Canada, France, India, Japan, Korea, New Zeland, Norway, Sweden, Switzerland, the United Kingdom and the World Bank. The following funders also contributed vital W2 funding: Australia, China, the United Kingdom (DFID) and USAID.

Overcoming smallholder challenges with biotechnology

From breeding to bugs, a new FAO publication looks at biotechnologies at work in small-scale crop, livestock and fish production

29 October 2013, Rome – A new FAO publication calls for greater national and international efforts to bring agricultural biotechnologies to smallholder producers in developing countries.

The publication, Biotechnologies at Work for Smallholders: Case Studies from Developing Countries in Crops, Livestock and Fish, asserts biotechnologies can help smallholders to improve their livelihoods and food security.

Biotechnologies at Work for Smallholders covers 19 case studies in crops, livestock and fisheries, written by scientists and researchers worldwide. It describes the practical realities and experiences of taking biotechnology research and applying it in smallholder production of bananas, cassava, rice, livestock, shrimp and more, in different parts of the developing world.

The case studies encompassed a wide range of biotechnologies. They included older or “traditional” ones like artificial insemination and fermentation, and cutting-edge techniques involving DNA-based methodologies – but not genetic modification.

The publication was prepared by a multi-disciplinary team at FAO as part of an agricultural biotechnologies project partially funded by the Government of Canada.

“With the right institutional and financial arrangements, governments, research institutions and organizations can help to bring biotechnologies to smallholders, improving their capacity to cope with challenges like climate change, plant and animal diseases, and the overuse of natural resources,” said Andrea Sonnino, Chief of FAO’s Research and Extension Unit.

Case studies

Four case studies were from India, two from China and one each from Argentina, Bangladesh, Brazil, Cameroon, Colombia, Cuba, Ghana, Nigeria, South Africa, Sri Lanka, Tanzania and Thailand.

Researchers used their knowledge of DNA markers to develop a flood-tolerant rice variety in India with a potential yield of 1-3 tons per hectare more than previously used varieties, under flood conditions. After being released in 2009, the new variety, Swarna-Sub1, spread rapidly and was used by three million farmers in 2012.

“In summary, submergence-tolerant varieties provided opportunities for improving and stabilizing yields in flash flood-affected areas, significantly contributing to national food security,” stated Uma Singh and colleagues from the International Rice Research Institute (IRRI) who prepared the case study.

In China, the Jian carp was developed using within-family genetic selection and gynogenesis (a reproductive technology resulting in all-female offspring that have only received genes from their mother). The Jian carp is now grown on about 160,000 fish farms and makes up over 50 percent of common carp production in China.|

In northern Cameroon, the use of DNA-based diagnostic tools in the field allowed veterinary authorities to quickly diagnose outbreaks of Peste des Petits Ruminants, a highly contagious viral disease affecting goats and sheep. Rapid and accurate disease diagnosis meant that the authorities could stamp out these outbreaks and stop the spread of the fatal disease to other flocks.

“Without this rapid response, thousands of sheep and goats would likely have succumbed to the disease during these outbreaks, leading to millions of CFA francs in losses,” affirmed Abel Wade and Abdoulkadiri Souley from the National Veterinary Laboratory (LANAVET) in Cameroon.

The editors say biotechnologies can improve crop-, livestock- and fish-related livelihoods by boosting yields and enhancing market access. Introducing new and traditional biotechnologies on family farms can also keep production costs down and improve sustainable management of natural resources.

Lessons learned

The publication offers lessons from the case studies which can be used to inform and assist policymakers in making decisions on programs involving biotechnologies. High up on the list was the need for national political commitment to improving smallholder productivity and livelihoods; financial support from non-governmental sources to supplement national efforts; and, long-term national investment in both people and infrastructure linked to science and technology.

The publication also found international and national partnerships were vital for achieving results, as was the sharing of genetic resources, techniques and know-how across national and continental borders.
