以两个单性结实性不同的雌雄同株黄瓜自交系构建的4世代群体为试材，采用植物数量性状主基因+多基因混合遗传模型联合分析方法，对南京江宁和河北昌黎两地雌雄同株黄瓜单性结实性遗传进行了比较研究.结果表明：不同生态环境下，雌雄同株黄瓜单性结实性遗传均符合E-1-1模型，受2对加性-显性-上位性主基因+加性-显性多基因控制，存在基因型与环境互作效应.但是，不同环境条件下F1的遗传倾向和遗传参数不同，F2的主基因遗传率为42.1%～97.5%，其遗传差异主要由黄瓜结果期两地日照和温度差异所致.强单性结实黄瓜品种选育以双亲均为强单性结实材料为宜，杂种后代宜在不同生态条件下选择鉴定.
By using the mixed major gene plus polygene inheritance model of quantitative traits, a joint analysis of four generations obtained after cross between two monoecious inbred lines was made to study the inheritance of parthenocarpy in monoecious cucumber in Jiangning (Nanjing) and Changli(Hebei). The interactions between genotype and environment were detected, and the inheritance of parthenocarpy in the monoecious cucumber was fitted in E-1-1 model and controlled by two additive-dominant-epistatic major genes and additive dominant-polygene under different eco environments. The F1 tendency and genetic parameters of the parthenocarpy were different, and the major gene heritability of F2 ranged from 42.1% to 97.5%, which was mainly due to the differences in sunlight intensity and air temperature during fruit-setting period at the two locations. It was suggested that the parents should be highly parthenocarpic in breeding program, and the characterization of parthenocarpy should be conducted under different
eco-environments.
