摘要
采用6×6完全双列杂交，按Hayman模型对丝瓜霜霉病抗性进行遗传分析研究结果表明：抗性的一般配合力和特殊配合力均重要；该性状适合“加性-显性”模型：以加性效应为主，表现为不完全显性，显性基因比例较高；狭义遗传力hN2＝69．63％；加性基因至少为4对．
The resistane heredity of Ridgegourd downy mildew was studied by a diallel cross arnong six culivare. The results showed that both general companing ability and specifil companing ability were important to resistance; the heredity of resistance could be explained by the additive dominative genehcal model. The ratio of dominant gene by recessive alleles, heritability in narrow sense was 69. 63%. The least number of additive gene was 4.
