Abstract

The embryo, cytoplasmic, and maternal heterosis for erucic acid content (EAC) and glucosinolate content (GLS) of rapeseed (Brassica napus L.) were studied by using the genetic models for quantitative traits of seeds in diploid crops. Eight parents were included in a diallel mating design in two years. It was found that the heterosis of EAC and GLS was simultaneously controlled by genetic main effects and genotypexenvironment (GE) interaction effects. The general heterosis of most crosses for EAC was significantly positive, while it was not for GLS. The general heterosis was more important for two quality traits of rapeseed because of the low GE interaction heterosis in both years, especially for GLS. Among different genetic systems, significant positive embryo general heterosis and the negative maternal general heterosis were found for EAC and GLS in most hybrid crosses. Some hybrids with significant negative interaction heterosis were detected for either of EAC or GLS. In general, maternal general and interaction heterosis was more important for reducing EAC and GLS of rapeseed.

甘蓝型油菜芥酸和硫代葡萄糖苷含量杂种优势遗传效应分析

摘要采用二倍体作物种子数量性状遗传模型，研究了油菜(Brassica napus L.)胚、细胞质和母系在芥酸含量(EAC)和硫代葡萄糖苷含量(GLS)方面的杂种优势。八对亲本在两年内被纳入双列杂交设计。结果表明，EAC和GLS的杂种优势同时受遗传主效应和基因型-环境互作效应的控制。EAC多数杂交的一般杂种优势显著正，GLS则不显著正。油菜两种品质性状均表现出较低的互作杂种优势，其中GLS杂种优势尤甚。在不同的遗传系统中，EAC和GLS在大多数杂交组合中均表现出显著的胚一般杂种优势正、母一般杂种优势负。有的杂种在EAC或GLS上均表现出显著的负互作优势。总体而言，母系一般杂种优势和互作杂种优势对降低油菜籽EAC和GLS更为重要。
