摘　　要：在自然发病条件下,鉴定了38份南瓜自交系和部分杂交组合对白粉病的抗病性。结果表明:不同南瓜自交系对白粉病的抗病性存在显著差异。其中无免疫类型,高抗类型和抗病类型均为3份,占所有鉴定自交系的7.89%;中抗类型11份,占所有鉴定自交系的28.95%;感病类型21份,占所有鉴定自交系的55.26%。各杂交组合间抗性也存在显著差异。The Resistance to the powdery mildew disease of 38 Pumpkin inbred-lines was estimated under natural circumstance. The results showed that remarkable difference was existed among the different pumpkin inbred lines. There were no immune types. There were 3 highly disease-resistance and 3 disease-resistant types, which occupied 7.89%. There were 11 middle disease-resistant types, which occupied 28.95%. There were 21 disease-susceptible types, which occupied 55.26%. Remarkable difference is existed among the hybrid combinations.
