| 摘 要： | 对没核质基因要交种的产量性状进行了分析。结果表明，不同核质遗传背景杂种的产量差异主要是由核基因型不同所致；不育胞质对杂交种的产量性状具有一定的正效应，Ｃ和Ｅ型不育胞质效应值分别达３．７３％和８．０７％，不育包质杂种的产量还受生态环境条件的影响。

| Abstract: | Analysis have been carried out on the yield of corn hybrids with different genotypes. The results show that the yield differences of hybrids with different genetic backgrounds are mainly due to the various nuclear genotypes. Sterile cytoplasms have some positive effect on the yield of hybrids. The yield of the hybrids with sterile cytoplasm can also be affected by the ecological environments. |
