黄瓜抗白粉病基因AFLP标记的SCAR转换

Development of a SCAR Marker Linked to Cucumber Powdery Mildew Resistance Gene from an AFLP Marker

将黄瓜抗白粉病相关基因的1个共显性AFLP标记转换为简单实用的SCAR标记。应用该SCAR标记对36个已知田间白粉病抗性的黄瓜材料进行了盲测,测定结果与其田间抗病性吻合率高达94.5%,表明该标记可以用于黄瓜白粉病的分子鉴定。

The co-dominant AFLP marker was successfully converted into co-dominant SCAR marker. Powdery mildew resistance of 36 known cucumber lines were tested by SCAR markers, and the results indicated that the resistance tested was consistent with their field performance by 94.5%, which further confirmed the feasibility of the SCAR marker in MAS for cucumber powdery mildew.
