Identification of a gene for resistance to wheatgrass powdery mildew fungus in the common wheat cultivar Chinese Spring

A gene for resistance to Erysiphe graminis was detected in Triticum aestivum cv. Chinese Spring, strain Salmon, T. compactum cv. No. 44, and T. spelta var. duhamelianum, using a hybrid culture derived from E. graminis f. sp. agropyri × E. graminis f. sp. tritici. The gene was located on the short arm of chromosome 6B and designated Pm11. Pm11 was considered to be involved in the resistance of wheat to the wheatgrass powdery mildew fungus.Key words: wheat, resistance, powdery mildew, Erysiphe graminis.
