甜瓜抗白粉病鉴定

Identification of Resistance to Powdery Mildew on Melon

利用风媒接种方法在空调温室初步鉴定了 8份甜瓜一代杂种品种和 12份甜瓜地方品种对白粉病菌的抗性。结果表明 ,8份一代杂种品种均高度感病 ,在 12份地方品种资源中 ,1份资源宁夏厚皮甜瓜免疫白粉病 ;1份资源河套密瓜存在免疫株系和感病株系 ;而其它均感病。

In this study,the resistance to powdery mildew in 8 F 1 hybrid varieties and 12 landraces of melon in air conditioned greenhouse was preliminarily identified by wind media inoculation.The results showed that 8 F 1 hybrids were susceptible.Most of landraces were susceptible,1 landrace was immune,and 1 landrace had an immuned line and four susceptible lines. This indicated that population of landraces have resistant genes which have a potential value to melon breeding.
