本试验对山东四号等3个大白菜(F1)亲本种株进行了考种。结果表明,大白菜单株种子产量主要分布在一、二次分枝上。主苔、一次枝、二、三次枝种子产量占全株种子产量的比率分别为6%~8%、43%、50%和6%~8%;各分枝种子千粒重大小依次为主枝>一次枝>二次枝>三次枝。各构成性状与单株种子产量的相关分析表明:单株种子产量与一次分枝数、一次分枝有效角果数、二次分枝数及有效角果数等性状呈显著或极显著相关。通径分析与相关分析结果一致。
In this experiment, three Chinese cabbage (F1) parental strains such as Shandong No.4 were tested. The results showed that the seed yield of Chinese cabbage was mainly distributed on the primary and secondary branches. The ratio of the seed yield of main moss, primary branch, secondary branch and secondary branch to total plant seed yield was 6% -8%, 43%, 50% and 6% -8%, respectively; A branch> two branches> three branches. The correlation analysis of individual traits and single seed yield showed that the seed yield per plant was significantly or very significantly related to the number of primary branches, the number of primary effective pods, the number of secondary branches and the number of effective pods per plant. Path analysis is consistent with the correlation analysis.
