发现抗白粉病基因Ml（La）位于大麦第2染色体上。我们建议将该位点命名为MlLa。对72个染色体加倍的春型后代进行了连锁分析，这些后代来自冬季变种‘Vogelsanger Gold’和春季变种‘Alf’之间的杂交。构建了一个2号染色体的图谱，其长度为119 cM，两侧有两个过氧化物酶基因位点。除了Laevigatum抗性位点的地图包括9个RFLP标记，两个过氧化物酶基因位点和大麦中的六行位点。
The powdery mildew disease resistance gene Ml(La) was found to belong to a locus on barely chromosome 2. We suggest 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 nine RFLP markers, the two peroxidase gene loci and the six-row locus in barley.
