采用粒荚比不同亲本进行杂交，对Ｆ１代及Ｆ２代粒荚比的遗传进行了分析。结果表明，Ｆ１代粒荚比表现出一定的正向优势；Ｆ２代粒荚比表现出一定的正向优势；Ｆ２代粒荚比有广泛分离，属于数量性状遗传；Ｆ２代广义遗传力各组合平均为５１．９％。
The pods were crossed with different parents, and the inheritance of the pod ratio in F1 and F2 generations was analyzed. The results showed that the grain-pod ratio of F1 generation showed a certain positive advantage; the grain-pod ratio of F2 generation showed a certain positive advantage; the grain-pod ratio of F2 generation was widely separated and belonged to quantitative trait inheritance; The average is 51.9%.
