Germplasm from the USDA-ARS National Small Grains Germplasm Collection (NSGC) will be screened utilizing Amplified Fragment Length Polymorphism (AFLP) and Simple Sequence Repeat (SSR) markers for cladistic analysis. Caldistic analysis will be used to determine if stem rust resistant germplasm arose from a monophyletic origin or if multiple sources of novel resistance are represented within the germplasm collection. Develop genetic mapping populations to characterize resistance alleles to Ug99 in resistant cultivars. Documents SCA with Washington State University.
