摘要： Cucumis species germplasm was evaluated for resistance to the root-knot nematode, Melodogyne incognita. The disease index (DI) score for Cucumis hystrix was smaller than for the susceptiple control C. sativus cv. Beijingjietou. Additionally, numerouslarge galls were found on cv. Beijingjietou, while only a few small galls were found on C. hystrix. Cucumis hystrix infected with M. incognita also had more lateral roots compared to the susceptible control. Furthennore, interspecific progenies derived from the cross between C. hystrix and cv. Beijingjietou had a high level of resistance to M. incognita. Thus, C. hystrix could serve as a valuable M. incognita-resistant source for cucumber improvement.
