用遗传相关、遗传通径分析等分析方法，通过电子计算机对３２个早熟红菜薹品种（系）的５个性状进行了统计分析。试验结果表明，单株产量受多因素影响，其中孙薹数、主薹重、侧薹重对单株产量的直接影响显著，且为正值，而孙薹重对单株产量的直接影响为负值。育种中，早期应进行主薹重的选择，中后期分别对单株侧薹重、孙薹数进行定向的选择，同时还应考虑各性状问的遗传相关，以选出高产的红菜薹新品种。
By means of genetic correlation and genetic path analysis, five characters of 32 cultivars of early red flowering Chinese cabbage were analyzed by computer. The results showed that the yield per plant was affected by many factors. Among them, the direct effects of the number of sun-bolting, the main bolting weight and the lateral bolting weight on yield per plant were significant and positive, while the direct impact of the yield of sun bolting weight on the yield per plant was Negative. Breeding, the early selection of the main sedge weight should be carried out in the late, respectively, on the side of the boll weight per plant, the number of sedge to choose directional, and should also consider the genetic interrelated genetic question asked to select high-yield red sedge Variety.
