| 摘要: |
| 提出了与相关变异、间接选择和综合选择有关的一个新的遗传参数，即决定系数遗传力，可定义为选择性状与目标性状的遗传协方差除以选择性状的表型标准差和目标性状的遗传标准差之积。本文证明了利用决定系数遗传力可以把间接选择与直接选择统一到一个公式中来，且把综合选择指数与通径分析统一起来，并讨论了它的应用。 |

| Determinant Coefficient Heritability and Its Application in Animal Breeding |

| Abstract: |
| A new genetic parameter,determinant coefficient heritability,concerning correlated variation,inderect selection and comprehensive selection is proposed in this paper,which can be defined as that a genetic covariance of selective and objective traits is divided by the product of selective trait's phenotypic standard deviation multiplying objective trait's genetic standard deviation.THis paper proves that with the determinant coefficient heritability,indirect selection can be integrated with direct selection into one formula,and also comprehensive selection index with path analysis method. In addition,its application has been discussed. |
| Key words: indirect selection,comprehensive selection,determinant coefficient heritability |
