摘　　要：By natural field identification, the resistance of Chinese wild Vitis to Uncinula necator and its inheritance in F1 generation were studied with 35 clones of 9 Chinese wild Vitis species, 171 F1 individuals of 4 inter-species cross between Chinese wild Vitis and Vitis vinifera cultivars, and 16 individuals of self-pollinated Chinese wild Vitis. Results showed that the phenotypes of resistance to Uncinula necator in Chinese wild Vitis and its F1 generation were rich and diverse. Based on the segregation of resisitance to Uncinula necator in the progenies resulted from both interspecific hybridization and self-pollination, of Chinese native wild Vitis species and clones were controlled by poly genes showing dominant independent heredity. Minor resistant genes were also exist in Chinese wild susceptible Vitis species and clones.By natural field identification, the resistance of Chinese wild Vitis to Uncinula necator and its inheritance in F1 generation were studied with 35 clones of 9 Chinese wild Vitis species, 171 F1 individuals of 4 inter-species cross between Chinese wild Vitis and Vitis vinifera cultivars, and 16 individuals of self-pollinated Chinese wild Vitis.
