摘要
对 2 1株黑塌菜 (BrassicacampestrisL sspchinensisMakionVar rosularisTsenetLee)的 2 1个性状进行了相关分析、回归分析和通径分析。结果表明 ,单株种子产量与一、二级侧枝的花数、枝条数、荚数、种子数及全株的花数、荚数、种子数呈极显著或显著的正相关 ;全株荚数对单株种子产量的直接作用最大 ;通过增加全株荚数、全株花数。
Analyses were performed of correlation, multiple regression and path coefficient on components of seed yield per plant of Heitacai(Brassica campestris L ssp chinensis Makino var. rosularis Tsen et Lee) . The results showed: the seed yield per plant was significantly correlated with the number of branches, flowers, shells and seeds of primary branches or secondary branches and the number of flowers, shells and seeds of the whole plant. The number of shells of the whole plant had the greatest direct effect on the seed yield per plant. The seed yield per plant could be raised by increasing the number of shells or flowers of the whole plant and that of primary branches or secondary branches.
