Leaf rust, caused by fungus Puccinia triticina, is an important foliar disease of wheat worldwide. Breeding for race-nonspecific resistant cultivars is the best strategy to combat this disease. Aegilops tauschii, D genome donor of hexaploid wheat, has provided resistance to seve…

Virulence of Puccinia recondita (leaf rust) and P. graminis f. sp. tritici (stem rust) was studied to provide a guide in breeding wheat and understanding pathogen evolution. No morphological differences exist among phenotypes, so virulence was used as a marker. For leaf and stem…
