试验以5个大白菜高代自交系作亲本,按Griffing Ⅱ完全双列杂交遗传设计配制15个杂交组合,在2个施氮水平下(300 kg·hm~(-2)和不施氮),进行大白菜硝酸盐含量配合力和遗传力分析.结果表明,大白菜硝酸盐含量的一般配合力方差占主导地位;加性效应和非加性效应对大白菜硝酸盐含量都有重要作用,但以加性效应为主,广义遗传力较高,狭义遗传力中等.

Total five inbred lines with different nitrogen using efficiency(NUE)in Chinese cabbage were selected as the experimental samples.Total 10 hybdd combinations were designed according to Griffing Ⅱ principle.The combining ability and heritability were analyzed with 10 hybrid combinations and 5 inbred lines under the high N(300 kg·hm~(-2))and the low N(no N)．The results showed that the variance of general combining ability was predominant;both additive variation and non-additive variation were significant in the nitrate content at two N levels,the additive effect played more important roles;the broad-sense heritability was high and the narrow-sense heritability was middle.
