对随机选取的国内外22份黄子白菜型油菜和22份褐子白菜型油菜进行了种皮色泽的显隐性关系鉴定、黄子性状的等位性测验以及遗传多样性分析。结果表明,黄子白菜型油菜与褐子白菜型油菜配组的杂交组合中,部分组合的F1种皮色泽呈现父本的种皮色泽,表现出花粉直感现象;自然界中存在多种白菜型油菜黄子类型,鉴定出的3种黄子白菜型油菜与褐色白菜型油菜的F2种皮色泽均为褐色,表明黄子性状对于褐子性状为隐性;分子标记方差分析结果显示,白菜型油菜的生长习性所解释的遗传变异大于种皮颜色所解释的遗传变异,表明国外不同生长习性的黄子白菜型油菜资源可用于国内黄子白菜型油菜遗传基础的拓宽。
A total of 22 randomly selected domestic and oversea Brassica campestris and 22 samples of Brassica campestris were identified by recessive relationship of seed coat color, allelopathic test of yellow trait and genetic diversity analysis. The results showed that in the cross combination of yellow cabbage and rapeseed (Brassica campestris spp.), The seed coat color of F1 seed coat of some combinations showed the color of the seed coat of the male parent and showed the phenomenon of direct pollen observation. There were many cabbage rape in nature Yellow type, identified F3 seed coat of Brassica campestris and Brassica campestris F2 color are brown, indicating that yellow trait is recessive for the brown trait; molecular marker analysis of variance showed that Brassica campestris The genetic variation explained by the growth habit is greater than the genetic variation explained by the seed coat color, indicating that the foreign yellow cabbage rape resources with different growth habit can be used for broadening the genetic basis of domestic yellow cabbage rape.
