Abstract

Genetic characterization of powdery mildew resistance genes were conducted in common wheat cultivars Hope and Selpek possessing resistance gene Pm5, cvs. Ibis and Kormoran expressing resistance gene Mli, a backcross-derived line IGV 1-455 and a Triticum sphaerococcum var. rotundatum Perc. line Kolandi. Monosomic analyses revealed that one major recessive gene is located on chromosome 7B in the lines IGV 1-455 and Kolandi. Allelism tests of the F₂ and F₃ populations involving the tested resistant lines crossed with either cv. Hope or Selpek indicated that their resistance genes are alleles at the Pm5 locus. The alleles are now designated Pm5a in Hope and Selpek, Pm5b in Ibis and Kormoran, Pm5c in T. sphaerococcum var. rotundatum line Kolandi, and Pm5d in backcross-derived line IGV 1-455, respectively.
