| 摘要: |
| 采用通径分析的决策分析方法，对表型方差最大主成分性状建立了通径分析化模型，进而完成了对其的决策分析。文中给出了判断主成分中主载性状、限制性状及中间性状的方法，便于育种者根据个体的性状表现来选择，以达到对Fi选择所期望得到的遗传进展。 |

| The decision-making analysis of the biggest variance of phenotype traits with principal component |

| Abstract: |
| By using decision-making analysis of path analysis,this paper built a path analysis model for the biggest variance of phenotype traits with principal component and completed decision-making analysis and showed a way to judge the main weight-bearing trait,confinement trait and intermedial trait from principal component. So breeding operator can choose the traits from individual expression to achieve the expectation of genetic process by selection. |
| Key words: phenotype combination character principal component path analysis decision-making analysis |
