The International Wheat Yield Partnership (IWYP), a partnership of public sector agencies and private industry focusing on innovations in wheat breeding for significant yield increases, recently released its 2017-2018 Annual Report. Many new research discoveries have been recorded over the last year, from germplasm with traits to improve genetic yield potential to molecular genetic markers associated with a target trait and new methods and technology to improve screening of individual wheat lines.
Accomplishments include making wheat lines with higher biomass and grain yields available for release in national programs, validating the hypothesis that combining parents with high biomass and good harvest index can boost genetic gains. IWYP researchers have also made publicly available new wheat lines with increased grain size and spike morphology, which several breeding companies in the UK, Europe and Brazil have requested. Yield trials have also led to the discovery of several physiological trait lines that outperform the best local and International Maize and Wheat Improvement Center (CIMMYT) check varieties in over 27 environments.
The Partnership, which includes 30 projects in more than 50 laboratories in 12 countries, is now in its third year. Outputs from its earliest projects are currently being validated and integrated in a prebreeding pipeline at the IWYP Hub at CIMMYT for development into pre-products. This ensures the best “toolbox” of new traits, genetics, and technology to reach its critical challenge of raising genetic wheat yield potential 50 percent by 2035.
