    摘要:

    用长果自交系S161318和短果自交系KN41531作亲本进行杂交、自交和回交。应用数理遗传学原理分析各世代的跗效应,结果表明:有棱丝瓜果长遗传方式属数量遗传,其遗传效应符合加必生遗传模型,以加必效应为主,控制果长性状的最少基因数目为4对果长的狭义遗传力为67.06%。

    Abstract:

    Crossing, self crossing and backcrossing were conducted with parents which have long fruit and short fruit. The data of experiment were analyzed by applying principle of quantitative genetics and the results showed that the fruit length of angular sponge gourd was a quantitative character controlled by 4 pair of genes. The genetic pattern of fruit length is in accord with pattern of additive dominance. Among all the genetic components of fruit length, the additive is predominant. The narrow heritability is 67.07%. It showed that applying cross breeding to fruit length of angular sponge gourd is better and selecting fruit length character in early generation is available.
