Technical Abstract: Public wheat breeding programs are responsible for the development of the majority of commercial varieties grown in the United States. For the wheat industry to remain competitive, these programs must integrate new technologies into conventional breeding efforts. USDA-ARS Regional Genotyping Laboratories for wheat and other small grains were established to assist programs in the practical use of marker assisted selection (MAS) through high-throughput DNA extraction and marker screening procedures. In addition, a consortium of public wheat breeding and genetics programs was formed in 2001 that has worked to introgress more than 23 disease resistance genes and 21 quality-related gene variants into adapted wheat parents of different market classes. As information from the wheat EST project and the rice genome sequence have become available, they been used to target new markers linked to agronomically important wheat genes. Strategies for deployment of multiple disease resistance genes in forward breeding programs using these resources will be presented.
