Inheritance of stripe rust resistance in wheat cultivars used to differentiate races of Puccinia striiformis in North America

Inheritance of stripe rust resistance in 13 wheat (Triticum aestivum) cultivars used to differentiate races of Puccinia striiformis in North America was determined using nine North American races of the pathogen. The differential cultivars, which were resistant to specific races, were crossed with cultivars susceptible to the specific races. We found that Lemhi, Chinese 166, Riebesel 47/51, and Tyee each have a single resistance gene; Heines VII, Moro, Druchamp, Produra, Stephens, Lee, and Fielder each have two resistance genes; and Paha and Yamhill each have three resistance genes (...)
