摘　　要：选用大白菜3个生态型的6个高代自交系进行完全双列杂交,对其干物质、维生素C、可溶性糖、有机酸、粗纤维和氨基酸含量进行遗传效应分析。结果表明,维生素C、有机酸、干物质及粗纤维含量符合加性-显性-母体效应(ADM)遗传模型,其狭义遗传力分别为53.1%、13.5%、38.3%和28.2%;可溶性糖及氨基酸含量符合加性-显性(AD)遗传模型,狭义遗传力分别为18.4%和40.3%。可溶性糖与干物质含量呈显著正相关,相关系数为0.746;维生素C与干物质含量呈显著正相关,相关系数为0.293,与有机酸、粗纤维含量呈显著负相关,相关系数分别为0.305和0.366。Genetic effects of dry matter, vitamin C, soluble sugar, organic acid, crude fiber and amino acid contents in Chinese cabbage (Brassica campestris L. ssp. pekinensis)were analysed for a set of 6×6 diallel crosses with six inbred lines of three ecotypes. The results showed that the genetics of vitamin C, organic acid, dry matter and crude fibre content was appropriate to the additive-dominant-maternal model while the inherence of the soluble sugar and amino acid was appropriate to the additive-dominance model. The estimated narrow heritability of vitamin C, organic acid, dry matter and crude fibre contents were 53.1%, 13.5%, 38.3% and 28.2%.The estimated narrow heritability of soluble sugar, amino acid contents were 18.4% and 40.3% respectively. It is observed that there was a significant positive correlation between the content of souble sugar and dry matter, the content of vitamin C and dry matter, the coefficient is 0.746 and 0.293 respectively; however , there was a significant negative correlation between the content of vitamin C and crude fibre, the content of vitamin C and organic acid, the coefficient is 0.366 and 0.305, respectively.
