Yang Jianping,Liu Weixin et al. (Dept.of Hort.,Shandong Agri.Univ.,Taian,China 271018)
Some seed plant characters of three F 1 Chinese cabbage have been evaulated.The results are as follows.Seed yield per plant is mainly distributed on the lst and 2nd class branches.The percentage of branch seed yield to total seed yield (Main、Ⅰ、Ⅱ、and Ⅲ branch) is 6%～8%、43%、50% and 6%～8% respectively.The distribution of seed weight per 1000 grains is in the order of main branchlst class branch2nd class branch3rd class branch.Correlation analysis shows that seed yield per plant is signifcantly correlated with branch number and valid pod percent of the lst or 2nd branch.The results of path analysis are the same as that of correlation analysis.
