【摘要】 黄瓜白粉病是影响黄瓜生产的主要病害,为建立黄瓜抗白粉病分子标记辅助选择体系,我们以黄瓜抗白粉病亲本WIS2757和感白粉病亲本19032以及它们的F2群体为试材,采用SSR分析技术,对相关抗性基因的连锁分子标记进行了研究。获得了2个与黄瓜白粉病主效抗病基因连锁的SSR分子标记SSR97-200,SSR273-300,连锁距离分别为5,13 cM,这些SSR标记可以作为黄瓜抗白粉病辅助选择的分子标记。更多还原

【Abstract】 Powdery mildew was one of the major diseases in Cucumis sativus L.production.In order to establish its molecular marker-assisted selection system,we aimed to identify molecular markers linked to the resistant gene.With a F2 population between a resistant parent(WIS2757) and susceptible parent(19032),we found two co-dominant SSR markers SSR97-200 and SSR273-300 were linked to the powdery mildew resistant gene,the genetic distances was 5,13 cM respectively.These SSR markers could be useful in marker-assisted selection in cucumber breeding.更多还原
