| 摘 要： | 应用2个番茄自交系材料多心室和少心室进行正交、反交及回交,应用数量遗传学原理分析各世代的遗传效应.结果表明:多心室番茄果重遗传受多基因控制的数量遗传,其遗传效应符合加性-显性遗传模型,其中以加性效应为主,显性方差所占分量极小,属于不完全显性;控制果重的最少基因数目约是2对.多心室番茄果重狭义遗传力为36.36%.

| Abstract: | The heredity of locule number,fruit index,fruit weight,sepal number of tomato and correlation with locule number was analysed on the data from which two inbred lines of multi-locule and few-locule with significant difference crossed with each other and backcrossed with their F1,and thus generations including the parents were obtained.The result showed that fruit weight of malformed tomato was controlled quantitative heredity by polygene.The genetic model of fruit weight of malformed tomato was fitted for additive-dominance model,additive gene had more important effects and partial dominance.The fruit weight of malformed tomato was controlled by two major gene.The narrow inheritability was 36.36%. |
