摘要
以甜瓜‘WMR-29’抗病品系和感病品系‘伽师’(JS)、感病品系‘皇后’(HH)的回交群体BC1为试材,采用BSA和SSR分子标记辅助选择的方法,研究甜瓜‘WMR-29’品系对白粉病抗病基因的影响。结果表明:甜瓜‘WMR-29’品系对白粉病Podosphaera xanthii race 1的抗性受2个显性抗病基因控制,分别位于LGⅡ、LGXII连锁群上,并且找到与甜瓜抗白粉病基因紧密连锁的标记。
Taking the resistant lines‘WMR-29’and the susceptible strain‘Jiashi’（JS）,‘Queen’（HH）of the backcross population as experiment materials.The location of Podosphaera xanthii race 1resistance gene was performed by BSA（Bulked Segregation Analysis）and linked SSR（Simple Sequence Repeat）makers technology.The results showed that the resistance gene to powdery mildew in melon‘WMR-29’strains was controlled by two dominant genes,and it was located on LGⅡ,LGⅫ,and also found one marker was linked to powdery mildew resistant gene of melon.
