Breeding Pipeline

Scope and Approach: 

The breeding activities are central to providing the genetic gain in wheat that the Delivering Genetic Gain in Wheat project proposes. Breeding activities will be a targeted crossing program to combine targeted traits and genes and the selection of the best individuals from the segregating populations, through field phenotyping and application of molecular markers. Shuttle breeding between different field sites will achieve two generations per year for capturing targeted traits as well as enhancing the wide adaptation of resulting lines.


International yield trials and nurseries will be distributed to national partners for global performance testing and utilization in breeding and release as new superior varieties. Targeted breeding to develop high-yielding spring wheat germplasm by utilizing a Mexico-Kenya shuttle-breeding scheme.


This activity has been very successful in incorporating stem rust resistance into CIMMYT breeding materials and identifying high yielding wheat lines that combine rust resistance with other important traits and are distributed globally as International Trials and Nurseries. A portion of the budget for durum and winter /facultative wheat activities is included in this proposal to the foundation. Data generation and sharing will be encouraged and facilitated through the utilization of an open access database and direct interaction with national partners. New tools such as an open access data management platform will be integrated into the program. The breeding program also will focus on training scientists and technical staff in Mexico as well as in target regions, with special emphasis on empowering young women staff members.
