摘要: The genetic effects including genetic main and genotype x environment interaction effects (GE) for oleic acid content of rapeseed (Brassica napus L.) were studied with eight parents and their F-1 and F-2 during 1998-1999 by using genetic model for quantitative traits of seed in diploid plant. The results indicated that the heredity of oleic acid content (OAC) of rapeseed was simultaneously controlled by diploid embryo nuclear genes, cytoplasmic genes and diploid maternal plant nuclear genes as well as their GE interaction effects. Genetic main effects for OAC were more important than GE interaction effects. The total narrow-sense heritability for OAC was high (77.5%), and the general heritabilities were found to be larger than the GE interaction heritabilities. The predicted genetic effects indicated that Huashuang 3 and Zhong R-888 were better than other parents for improving OAC of offspring
