摘要: 选取茄子单性结实性差异显著的5个材料,采用完全双列杂交半轮配(含亲本)试验设计配
制杂交组合,利用蕾期人工去柱头的方法测定亲本及F。单性结实坐果率。统计分析表明:茄子单性结实性状遗传不符合“加性一显性”遗传模型,存在着非等位基因间的上位作用;单性结实性状可能受一组隐性基因控制,属隐性遗传。

Abstract: The combining abilities, heritability, correlation, aggression, and path for parthenocarpy were analyzed according to 10 hybrid CI'OSS made between 3 parthenocarpic lines and 2 non—parthenocarpic lines of eggplan t with half mating design.The results showed that the heredity of parthenocarpy was not correspondent with the additive-dominant mode1. Parthenocarpy was ma ybe controlled by a group of recessive genes as well as influenced by epitasis effect.

Key words: Eggplant, Parthenocarpy, Genetic analysis
