摘　　要：为明确四倍体南通矮白菜单株种子产量构成性状的关系,对12株四倍体南通矮白菜的16个单株种子产量构成性状进行了相关、回归、通径分析。结果表明,单株种子产量与二级分枝数等6个性状呈极显著或显著正相关,回归分析发现二级分枝数对单株种子产量贡献最大,通径分析表明二级分枝荚数对单株种子产量的直接、间接效应最大。综合分析,摘心是提高四倍体南通矮白菜单株种子产量简单有效的措施。In order to clarify the relationship between seed yield components of tetraploid Nantong dwarf pakchoi,correlation,regression and path analysis were carried out on 16 seed yield components of 12 tetraploid Nantong dwarf Chinese cabbage plants.The results showed that seed yield per plant was significantly or positively correlated with six traits such as secondary branch number.Regression analysis showed that secondary branch number contributed most to seed yield per plant.Path analysis showed that secondary branch pod number had the most direct and indirect effects on seed yield per plant.Comprehensive analysis showed that picking was a simple and effective measure to increase seed yield of tetraploid Nantong dwarf pakchoi.
