<i>PmAm</i>, a Broad-Spectrum Powdery Mildew Resistance Source Located on <i>Amblyopyrum muticum</i> Chromosome 6T, Is Transferred to Common Wheat
Powdery mildew (caused by <i>Blumeria graminis</i> f. sp. <i>tritici</i>) limits grain production and reduces grain quality in wheat. <i>Amblyopyrum muticum</i> (2n = 2x = 14, TT genomes), a wild relative of wheat, carries agronomically valuable traits, including resistance to powdery mildew, that have not been transferred to wheat. Here, a powdery mildew-resistant Chinese Spring-<i>Am. muticum</i> amphiploid was backcrossed to a powdery mildew-susceptible wheat cultivar, and homozygous resistant derivatives with broad-spectrum resistance were selected. Fluorescence in situ hybridization analysis identified chromosome substitution and compensating Robertsonian translocation lines involving chromosome 6T from <i>Am. muticum</i>.
