摘要: 在空调温室利用风媒接种方法对从国内外搜集的37份甜瓜种质资源进行了白粉病抗性鉴定,鉴定出69份抗源,其中国外抗源品种有2份;国内种业市场或育种单位搜集的当前推广的品种只有10份抗白粉病;在所鉴定的133份中国薄皮甜瓜和菜瓜地方品种资源中有6份甜瓜和1份菜瓜抗白粉病,表明中国甜瓜地方品种资源中蕴涵着潜在的改良甜瓜白粉病抗性的基因.抗源自交后代抗病株明显多于感病株,初步认为抗源基因的遗传可能表现为显性.

Abstract: We studied the resistance to powdery mildew in 357 varieties of melon in air-conditioned greenhouse by wind media inoculation.The result showed that 69 varieties were resistant,52 of which come from foreign varieties,10 of which from seed markets or research institutes in China.6 var.makuw a makino and 1 var.f lexuosus naud were resistant in 133 landraces on Melon.This indicated that the population of landraces has resistant genes which have a potential value to melon breeding.The number of resistant plants was bigger than that of susceptible plants in inbreeding off spring of resistant sources,and the inheritance of these resistant genes may be dominant.

Key words: Melon, Powdery mildew, Identification of resistant sources, Genetic analysis
