摘要: 以西瓜抗白粉病种质PI482246和感白粉病品种中信1号为亲本,建立了F2、BC1.1和BC1.2分离群体。从白粉病菌收集物中分离鉴定得到Px生理小种2 France,采用孢子悬浮喷雾法对各世代进行白粉病抗性苗期接种鉴定,并进行抗性遗传分析。试验结果表明,PI482246对Px生理小种2 France的抗性由一对不完全隐性单基因控制。

关键词: 西瓜, 白粉病, 生理小种鉴定, 抗性遗传

Abstract: The cross of watermelon PI482246,which is resistant to powdery mildew disease, and Zhongxin 1,which is susceptible to powdery mildew disease, were used to construct F2, BC1.1 and BC1.2progeny populations?The inheritance of resistancewas analyzed with Podosphaera xanthii race-France purified and identified from a collection of powdery mildew using spore spraying method in greenhouse. The results of cross tests indicated that the resistance carried by PI482246 to powdery mildew race-France was controlled by a single recessive gene and the resistance was incomplete recessive.

Key words: Watermelon, Powdery mildew, Physiological race identification, Resistance inheritance
