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病毒病的抗性。结果表明:不同南瓜自交系对病毒病的抗性存在显著差异。其中,无高抗和免疫的类型,抗病材料2份,占5.26%;中抗材料28份,占73.68%;感病材料8份,占21.05%;各杂交组合间抗性也存在显著差异。The resistances of 38 pumpkin inbred-line and part of hybrid combinations to the virus disease were evaluated under natural conditions.The difference of the different inbred lines was significant.There was no highly disease-resistance and immune types.There were 2 disease-resistant types,accounted for 5.26%,28 moderate disease-resistant types,73.68%,8 disease-infectious,21.05%,respectively.And among the hybrid combinations,there was significant difference in their resistances.
