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.展开更多
