Stripe rust, caused by Puccinia striiformis f .sp. tritici, has become an economically important fungal disease for the eastern United States in recent years. Breeding for stripe rust resistance has become a priority for the region. As part of the Coordinated Agricultural Project (CAP), breeding approaches that are likely to provide more durable disease resistance are being implemented. These include: mapping of quantitative trait loci associated with stripe rust resistance, marker assisted selection to pyramid major stripe rust resistance genes into advanced breeding material and searching for new sources of resistance among soft red winter wheat germplasm. Up to date progress in these areas is presented.
