Louisiana State University will identify and obtain sources of rust resistance in cooperation with the USDA/ARS Plant Science Research Unit (PSRU), and other collaborating breeding programs. These sources of resistance will be used as parents in the breeding program to introgress rust resistance into advanced breeding lines of winter wheat. Top and/or backcrosses to adapted elite lines will be made to develop desirable segregating populations. When available molecular markers for known sources of rust resistance will be used to characterize parental lines and in marker assisted transfer and selection of resistance. Segregating populations developed from the introgressions will be inbred and advanced using traditional and/or marker assisted breeding methods when markers are available. Pure lines selected from advance breeding populations will be genotyped using available molecular markers and phenotypes for reaction to rust will be obtained in cooperative disease screening experiments conducted in field, greenhouse and/or growth chamber trials. Elite lines having rust resistance will be evaluated in regional and uniform yield nurseries, and superior lines will be released as cultivars. Data and germplasm will be shared between ARS, Louisiana State University, and other collaborating scientists.
