The mas wheat project: impact of genomics on wheat breeding. Plant and Animal Genome Abstracts. Interpretive Summary:
Technical Abstract: In 2001 twelve wheat breeding center and research laboratories formed a consortium designed to increase the use of marker assisted selection (MAS) in public wheat breeding programs. The strategy of the project is to introgress by backcrossing more than 23 disease resistance genes and 21 quality-related gene variants in approximately 100 adapted parents from different market classes. The MASwheat project has completed the introgression of valuable genes into 78 wheat lines and 178 lines will be completed by Sept. 2005 when the project finishes. These new lines include adapted cultivars belonging to most of the US market classes. The consortium also developed new molecular markers, which were made publicly available in 23 scientific papers and through the project web site (http://maswheat.ucdavis.edu). This web site includes laboratory protocols for more than 22 traits, together with educational material. The impact of MAS methods in wheat breeding was discussed in 73 presentations to wheat growers, industry, and research meetings. This project resulted in a better integration of public wheat breeding programs and molecular laboratories, and in the development of the trained personnel and expertise required to implement MAS tools in active breeding programs. The MASwheat project also became a starting point of a more ambitious initiative that will integrate most of the wheat breeders in the US and the USDA genotyping centers in forward-breeding MAS strategies, and that will develop new markers for complex agronomic and quality traits.
