对１５个杂交组合１１３８株山葡萄种内杂交后代的花型进行了调查，结果表明：山葡萄花型的遗传符合Ｌｅｖａｄｏｕｘ（１９４６）的假说〔１〕，受Ｍ．Ｈ．Ｆ３个等位基因控制。野生状态下，雄花植株基因型为异质ＭＦ；目前发现唯一的两性花种质资源‘双庆’基因型为异质ＨＦ；雌能花植株基因型为ＦＦ；人工杂交以后可以产生基因型为ＨＨ的两性花植株和基因型为ＭＨ的雄花植株。
The floral patterns of 1138 crossbred hybrids from different grapevines of 15 hybrids were investigated. The results showed that the genetic pattern of the grapevine was consistent with the hypothesis of Levadoux (1946) [1]. H. F3 alleles control. In the wild, the genotype of male flower is heterogeneous MF. At present, the unique genotype of Shuangqing is the heterozygous HF, the genotype of female genotype is FF, and the genotype of female genitalia is FF HH bisexual plants and male genotype MH plants.
