摘要

摘要为研究黑麦(Secale cereale)对白粉病的抗性，对397个冬黑麦自交系进行了小麦蓝灰菌(Blumeria graminis f. sp. secalis)的敏感性试验。选择耐受性最强的50个品系和侵染性最强的50个品系进行比较。接下来对它们进行了4个标记的检测，这些标记与早先在普通小麦(Triticum aestivum)中发现的4个抗白粉病等位基因相关。虽然Pm3a标记与小麦抗白粉病基因相关，但我们只在冬黑麦的3个易感基因型中发现该标记。另外3个与黑麦蓝灰菌抗性基因相关的标记(Pm3b、Pm3c、Pm3d)在黑麦抗感基因型中均未发现。

A search for 4 specific markers linked to Pm3 alleles for resistance to powdery mildew (Blumeria graminis) in rye (Secale cereale)

Abstract To investigate powdery mildew resistance in rye (Secale cereale), 397 inbred lines of winter rye were tested for susceptibility to infection with Blumeria graminis f. sp. secalis. The 50 most tolerant lines and 50 most infected lines were chosen for comparison. They were next tested for the presence of 4 markers linked to 4 alleles for resistance to powdery mildew, identified earlier in common wheat (Triticum aestivum). We found Pm3a only in 3 susceptible genotypes of winter rye, although this marker is linked to the powdery mildew resistance gene in wheat. The other 3 markers linked to Blumeria graminis f. sp. secalis resistance genes (Pm3b, Pm3c, Pm3d) were found in neither resistant nor susceptible rye genotypes.
