Effect of wheat cultivar mixtures on populations of Puccinia striiformis races

Creator:

DiLeone, Julie A.

Abstract:

This study quantified the frequency of simple versus complex races of Puccinia striiformis Westend. in mixtures of wheat cultivars possessing different race-specific resistance genes. A simple race of a pathogen can infect only one component, and a complex race of the pathogen can infect two or more components of an...

Analysis of genetic resistance to barley stripe rust (Puccinia striiformis f. sp. hordei)

Creator:

Prehn, Doris A.

Abstract:

Stripe rust (Puccinia striiformis f. sp. hordei) is a serious disease of barley that can cause up to 70% yield loss in susceptible varieties. The fungus is moving northward, threatening major barley production areas in the US, where most cultivars are susceptible. Fungicides are available for control of stripe rust,...
