本文研究了油菜种间杂种后代株高与产量性状间的关系。结果表明:不同株高等级间的产量因素存在着显著的差异。株高与单株产量的关系呈二次曲线型、单株角果数对单株产量的直接相对作用最大,株高次之,千粒重最小.株高对产量的影响主要是通过增加单株角果数和每角粒数而间接发生作用。 In this paper, we studied the relationship between plant height and yield traits in rape interspecific hybrids. The results showed that there were significant differences in yield factors between different plant height classes. The relationship between plant height and plant yield was quadratic curve, and the number of pods per plant had the highest direct relative effect on plant yield, the plant height was the second, the grain weight per plant was the smallest.The effect of plant height on yield was mainly achieved by increasing the plant height The number of fruit and grain per angle and indirect effect.
