用矮脚黄白菜两用系中的才育株繁育而成的自交系和由其转育而成的萝卜胞质雄性不育系为母本,与10个不结球白菜自交系配制了20个组合。组合和其亲本在秋冬栽培期安排了4次重复的随机区组试验,应用同亲回归分析等数量遗传学方法,对雄性不育系的亲本选配及其特点进行了初步探索。试验结果表明,与矮脚黄白菜相比较,萝卜胞质组合单株重,单叶重、叶/柄比的遗传变异更多地受非加性遗传效应控制,与亲本性状值的相关系数有减小的趋势。萝卜胞质组合除了象矮脚黄白菜组合一样,要选择综合性状优良的亲本以外,还要注意广泛进行配组,及早进行配合力的测定。要多选用单位面积叶鲜重大和叶绿素含量高的材料作为亲本。 Inbred lines that were bred from the bred lines of the two plants of the yellow cabbage and the radish cytoplasmic male sterile lines that were transplanted from the broomcows were used as the female parent and 10 non-heading Chinese cabbage inbred lines were prepared 20 combinations. The combination and its parents arranged four repeated randomized block trials during the fall and winter cultivation stages. The genetic matching of the male sterile lines and their characteristics were preliminarily explored using quantitative genetic methods such as regression analysis of cousins. The results showed that the genetic variation of single plant weight, single leaf weight and leaf / stalk ratio of radish cytoplasm was more controlled by non-additive genetic effect than that of yellow cabbage, and the correlation coefficient with the value of parental traits Decreasing trend. Radish cytoplasm combination in addition to the same as the yellow cabbage combination, to select the elite parents of comprehensive traits, but also pay attention to a wide range of groups, early determination of the combining ability. To use more units per unit area of ​​fresh leaf and chlorophyll content as a parent material.
