摘　　要：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。This paper analysed six allocytoplasmic male sterile lines of Chinese cabbage on eleven factors composing of seeds output, which maked clear that pod number of single plant, first and second branch number, main stem leaf number, plant height highly positive correlated to single plant seed yield. Path coefficient analysis showed that the leaf number of main stem had the most effect on single plant seed yield, and pod number of single plant was the second. So, the two factors must be considered for selecting and breeding new varities.
