2nd call for proposals from the International Wheat Yield Partnership

By Jeff Gwyn/IWYP

COLLEGE STATION, Texas (December 16, 2016) –The International Wheat Yield Partnership (IWYP) is initiating its Second Competitive Funding Call by inviting creative, forward-looking proposals that seek to discover resilient and sustainable approaches to substantially increase the genetic yield potential of wheat, as defined by grain yield under the absence of stress, for the benefit of developed and developing countries. It is anticipated that wheat yield potential can be enhanced by:

  • Increasing carbon capture before floweringiwyp
  • Increasing biomass
  • Optimizing harvest index
  • Enhancing photosynthetic pathways
  • Specific changes in plant architecture
  • Modifying phenology, e.g., flowering time
  • Hybrid wheat system development
  • Root structure and growth
  • Faster / alternative breeding methods
  • Modeling to define best traits per environment

Advice for India’s rice-wheat farmers: Put aside the plow and save straw to fight pollution

By Mike Listman/CIMMYT

The Turbo Happy Seeder allows farmers to sow a rotation crop directly into the residues of a previous crop—in this case, wheat seed into rice straw—without plowing, a practice that raises yields, saves costs and promotes healthier soil and cleaner air.

EL BATAN, Mexico (November 28,2016) – Recent media reports show that the 19 million inhabitants of New Delhi are under siege from a noxious haze generated by traffic, industries, cooking fires and the burning of over 30 million tons of rice straw on farms in the neighboring states of Haryana and Punjab.

However, farmers who rotate wheat and rice crops in their fields and deploy a sustainable agricultural technique known as “zero tillage” can make a significant contribution to reducing smog in India’s capital, helping urban dwellers breathe more easily.

Since the 1990s, scientists at the International Maize and Wheat Improvement Center (CIMMYT) have been working with national partners and advanced research institutes in India to test and promote reduced tillage which allows rice-wheat farmers of South Asia to save money, better steward their soil and water resources, cut greenhouse gas emissions and stop the burning of crop residues.

The key innovation involves sowing wheat seed directly into untilled soil and rice residues in a single tractor pass, a method known as zero tillage. Originally deemed foolish by many farmers and researchers, the practice or its adaptations slowly caught on and by 2008 were being used to sow wheat by farmers on some 1.8 million hectares in India.

Wheat global impacts 1994-2014: Published report available

Cover_Page_01By Mike Listman/CIMMYT

EL BATAN, Mexico (April 8,2016)- Just published by CIMMYT and WHEAT, the report “Impacts of International Wheat Improvement Research 1994-2014,” shows that varieties on nearly half the world’s wheat lands overall — as well as 70 to 80 percent of all wheat varieties released in our primary target regions (South Asia, Central and West Asia and North Africa) — are CGIAR related. Other key findings include the following:

  • Fully 63 percent of the varieties featured CGIAR genetic contributions. This means they are either direct releases of breeding lines from CIMMYT and ICARDA or have a CGIAR line as a parent or more distant ancestor.
  • Yearly economic benefits of CGIAR wheat breeding research ranged from $2.2 to $3.1 billion (in 2010 dollars), and resulted from annual funding of just $30 million, representing a benefit-cost ratio of between 73:1 and 103:1, even by conservative estimates.
  • In South Asia, for example, which is home to more than 300 million undernourished people and whose inhabitants consume over 100 million tons of wheat a year, 92 percent of the varieties carried CGIAR ancestry.

Deadly disease wheat blast reaches South Asia

By Mike Listman/CIMMYT

EL BATAN, Mexico (April 7,2016)- One of the most fearsome and intractable wheat diseases in recent decades is wheat blast, caused by the fungus Magnaporthe oryzae.

First sighted in Brazil in 1985, blast is widespread in South American wheat fields, affecting as much as 3 million hectares in the early 1990s and seriously limiting the potential for wheat cropping on the region’s vast savannas.

Scientists harness genetics to develop more “solar”- and structurally-productive wheat

By Mike Listman/CIMMYT

CIUDAD OBREGON, Mexico (March 22, 2016)- In early outcomes, partners in the International Wheat Yield Partnership (IWYP) are finding evidence that increased photosynthesis, through high biomass, improvements in photosynthetic efficiency, and improved plant architecture, can help make wheat more productive, as the Partnership progresses toward meeting its aim of raising the crop’s genetic yield potential by up to 50% over the next 20 years.

This and other work, and particularly partners’ roles and operating arrangements, were considered at the first official annual IWYP Program Conference. This was held at the Norman E. Borlaug Experiment Station near Ciudad Obregón, Mexico, 8-10 March 2016, following the funding and commencement of the Partnership’s first eight projects, according to Jeff Gwyn, IWYP Program Director.

“The aim of the conference was for participants to learn about everyone else’s work and to integrate efforts to realize synergies and added value,” said Gwyn, noting that some 35 specialists from nearly 20 public and private organizations of the Americas, Europe, Oceania, and South Asia took part.

BIHAR, India (January 30, 2016)- In response to earlier summers and rising temperatures in South Asia, specialists in the CIMMYT-led Cereal Systems Initiative for South Asia (CSISA) have been encouraging farmers in India’s eastern Uttar Pradesh and Bihar to sow their wheat crop by mid-November, instead of the traditional date of late December.

According to R.K. Malik, a CSISA senior agronomist, farmers who sow their wheat at the traditional time can lose as much of a quarter of the crop in the spring heat wave, which can exceed 40 degrees Celsius and now arrives as early as March, instead of May, as was previously the case.

Funded by the U.S. Agency for International Development (USAID), the work is covered in the lead story of the January/February 2016 edition of the USAID periodical FRONTLINES.
