Localization of the Laevigatum powdery mildew resistance gene to barley chromosome 2 by the use of RFLP markers

The powdery mildew disease resistance gene Ml(La) was found to belong to a locus on barley chromosome 2. It is suggested that this locus be designated MlLa. Linkage analysis was carried out on 72 chromosome-doubled, spring-type progeny lines from a cross between the winter var 'Vogelsanger Gold...

Description
Summary:The powdery mildew disease resistance gene Ml(La) was found to belong to a locus on barley chromosome 2. It is suggested that this locus be designated MlLa. Linkage analysis was carried out on 72 chromosome-doubled, spring-type progeny lines from a cross between the winter var 'Vogelsanger Gold' and the spring var 'Alf'. A map of chromosome 2 spanning 119 cM and flanked by two peroxidase gene loci was constructed. In addition to the Laevigatum resistance locus the map includes 9 RFLP markers, the 2 peroxidase gene loci and the 6-row locus in barley.
