| 摘 要： | 研究不同类型杂交蓖麻F2代雌性单株的主穗性别可逆转性、有效分枝数、主穗长度、百粒重对选育效果的影响。试验结果表明:在主穗性别可逆转性和有效分枝数、主穗长度这两个性状上,3个参试材料比CK都极显著性。但在百粒重性状上,CSR8-5×OUC-5的F2代雌性单株比CK不显著,CSR8-5×DH-7的F2代雌性单株还极显著差于CK。通过对不同类型杂交蓖麻F2代雌性单株选育,筛选适应华南地区的综合性状的蓖麻F2代优良雌性单株。

| Abstract: | The sexual reversible of main spike, the effective branches, the length of main spikes and the weight of 100 grains of F2 female plants which came from different hybridizations was studied. The result showed that Contrasting with CK, the sexual reversible of main spike, the effective branches, the length of main spikes of three F2 female plants was extremely significant. But in weight of 100 grains, the female plants from the F2 of CSR8-SxOUC-5 was not significant, and the female plants from the F2 of CSR8-5x DH-7 was extremely significant lower. Throught F2 female plants of different hybridizations castor selected, F2 female plants of synthctizcd character castor are filtrated to fit to southern of China. |
