Interpretive Summary:

Technical Abstract: Barley and Cereal Yellow Dwarf Viruses continue to be a major disease problem in the Midwest and Southeastern parts of the US. A number of lines developed in the small grains breeding programs at Purdue University and University of Illinois do have significant resistance to these viruses. However, when the disease pressure is high the level of resistance within these lines does not appear to be sufficient. Also this resistance is most likely due to the pyramiding of a number of genes, which individually do not provide high levels of resistance. Moving this multi-gene resistance into adapted material for this wide growing region requires a significant amount of testing over multiple generations. Consequently, we are currently testing in the greenhouse and field a set of Avena strigosa and Avena sterilis accessions to identify lines which contain high levels of B/CYDV resistance. Preliminary analyses suggest that several of these lines are quite resistant. Those lines which contain significant levels of virus resistance will be used as resistance donors in the breeding program.
