Chromosomal location of genes for resistance to powdery mildew in common wheat (Triticum aestivum L. em Thell.). 5. Alleles at the Pm1 locus

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 i...

Zusammenfassung:	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/8Cc on 7A indicated that the resistance genes are alleles at the Pm1 locus. These alleles are now designated Pm1a in line Axminster/8Cc, Pm1b in MocZlatka, Pm1c in Weihenstephan Stamm M1N, and Pm1d in T. spelta var. duhamelianum, respectively.
