- 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。
- Abstract:
- 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 1 resistance 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.
