摘要
以 ８ 个大豆组合的杂种 ２ 代为试材，对其竞争优势进行了测定，发现有 ３ 个组合竞争优势较强，增产幅度达 １５．３％ ～２２．６％ ，并发现大豆杂种 ２ 代竞争优势强的组合有 １ 代优势较弱、且群体在株高等方面有较为一致的趋势，同时，分析了大豆杂种 ２ 代在目前生产上的利用前景。
The heterosis of 8 soybean F 2 generationswas tested. The results showed that 3 F 2s had stronger heterosis,the yields increased by 15.3%～22.6% compared with CK.The tendency that the combinations with strong heterosis in F 2 often had weak heterosis in F 1 and the plant height of F 2 population was relatively uniform was also found.
