| 摘 要： | 通过对油葵不育系、恢复系产量性状进行双列杂交分析 ,结果表明自交系间一般配合力和特殊配合力存在极显著、显著差异。F1的产量性状受亲本自交系的一般配合力和特殊配合力的共同影响 ,但一般配合力效应较特殊配合力的略大。自交系的一般配合力和特殊配合力间无明显相关关系。在杂交组合配制以及自交系的改良计划中 ,应首先在较高的一般配合力的基础上 ,同时要求有较高的特殊配合力方差

Evaluation of Combining Ability of Yield Properties of CMS Lines and Restoring Lines in Oil Sunflower |
| |
| Abstract: | Diallel crossing analysis of yield properties of two groups of inbred lines in oil sunflower showed that there are significant difference between their general combining ability (GCA) and specific combining ability (SCA).The results showed that the GCA and SCA of parental lines both played an important role in the yield of F 1 hybrids,but the effect of GCA on F 1 is greater than that of SCA.There is no obvious relationship between GCA and SCA.It is suggested that when the hybrids are developed and the inbred lines are improved,we should pay more attention on GCA of candidates as well as SCA. |
