Twelve near‐isogenic lines of wheat, Triticum aestivum L. em Thell . (aestivum group), each with a gene for resistance to Erysiphe graminis DC. ex Merat f. sp. trltici Em. Marchal, have been developed through a backcrossing program. Some have identical genes, but at least four different loci are represented. Those lines that represent genes for resistance at different loci, or different alleles al: any one locus, may be used as differentials in identification of cultures of the powdery mildew fungus. They are also well‐suited for critical genetic studies involving resistance to E. graminis tritici, and for research directed toward learning more about the nature of disease development.
