Abstract

 The chromosomal location and genetic characterization of powdery mildew resistance genes were determined in the common wheat lines MocZlatka, Weihenstephan Stamm M1N and in a resistant line of Triticum aestivum ssp. spelta var. duhamelianum. Monosomic analyses revealed that one major dominant gene is located on chromosome 7A in each of the lines tested. Allelism tests with Pm1 in the backcross-derived line Axminster/8*Cc on 7A indicated that the resistance genes are alleles at the Pm1 locus. These alleles are now designated Pm1a in line Axminster/8*Cc, Pm1b in MocZlatka, Pm1c in Weihenstephan Stamm M1N, and Pm1d in T. spelta var. duhamelianum, respectively.
