Durable Rust Resistance in Wheat

The ability of the world’s farmers to meet current and future demand for wheat is threatened by the highly virulent stem rust population emerging from East Africa. This Durable Rust Resistance in Wheat project mitigates the threat through coordinated pathogen surveillance activities and breeding initiatives. The purpose of the project is to reduce the world’s susceptibility to wheat stem rust diseases through international collaboration. It includes 22 research institutions around the world, each seeking to mitigate the threat of stem rust diseases through coordinated activities that will replace susceptible varieties with durably resistant varieties. The project aims to harness recent advances in genomics to introduce non-host resistance into wheat.

 

Objectives:

  • Improve the testing, multiplication and adoption of replacement varieties
  • Increase levels of global investments and coordination in stem research and development
  • Track and monitor stem rust populations
  • Invest in stem rust response phenotyping facilities
  • Develop durably resistant high-yielding varieties
  • Develop High-breeding value wheat lines with two or more selected rust resistance genes
  • Optimize the wheat improvement system in Ethiopia
  • Coordinate project management and communications.
