摘要: 以7个不同遗传来源的甘蓝型黄籽品系配制的完全双列杂交组合作为样本,对甘蓝型黄籽油菜主要性状进行通径分析。主要结果为:全株有效果数和株高对单株粒重有最大正向作用,通径系数分别为0.514和0.535。皮壳率对黄籽度有直接的最大负效应,通径系数为-0.798。

Abstract: A complete diallel of seven yellow-seeded rapeseed lines as samples, which come from different sources by using path analysis, was carried out. The main results showed that the number of siliqua per plant and the height of plant had a large positive effect on the yield per plant, path coefficient is 0.514 and 0.535 respectively. Whereas the seed coat ratio had a directly positive effect on the yellow degree, path coefficient is -0.798.
