| 摘要: |
| 建立了综合选择指数的通径分析化模型,即综合选择指数的相关遗传力分解模型,提出了综合选择指数的决策分析方法,从而使综合选择指数的路径信息最优化。提出了确定主选性状、辅助性状和限制性状的方法,便于育种者根据个体的性状表现进行选择。 |

| Decision analysis on comprehensive selection index |
|
|
| Abstract: |
| This paper establishes the path analytical model of comprehensive selection index,that is analyzing model on correlated heritability of comprehensive selection index.Decision analysis on comprehensive selection index is advanced to optimize its path information.The paper also shows ways to ascertain main selective,assistant and restrained trait,which allow breeders to select by individual phenotypes. |
| Key words: comprehensive selection index,path analysis,correlated heritability,decision analysis |
