通过６个大白菜胞质雄性不育系１１个构成产种量因素的相关分析，明确单株有效角果数、一、二级分枝数、主茎叶片数、株高与单株产种量呈高度正相关。进一步通径分析表明，主茎叶片数对单株产种量的直接效应最大，其次是单株有效角果数。在新品系选育和高产栽培方面都应着重考虑这两个主导因素。 Based on the correlation analysis of 11 constituent cytoplasmic male sterile lines of 6 Chinese cabbage, the number of effective pods, the number of primary and secondary branches, the number of main stem leaves, plant height and single plant production The species was highly positive. Further path analysis showed that the number of main stem leaves had the greatest direct effect on the yield per plant, followed by the number of effective pods per plant. In the new line of breeding and high yield cultivation should focus on these two dominant factors.
