| 摘 要： | 从猪蛋白质（酶）多态性和ＤＮＡ分子水平上估测出亲本种群间的遗传距离，探讨它们与基因杂合度及经济性状杂优率之间的关系，结果表明，亲本间遗传距离与基因杂合度呈正相关，与日增重、屠宰率的杂优率也呈正相关，与眼肌面积、后腿比例、瘦肉率、熟肉率的杂优率呈负相关。

| Abstract: | Parental genetic distances were evaluated by plasma protein(enzyme) polymorphisms and DNA molecular level. Their relationship with gene heterozygosities and heterosis of various traits were analyzed. The results show that parental genetic distance shows positive correlation with gene heterozygosities, heterosis of daily gain and dressing percentage, but negative correlation with the heteroses of loin eye area,ham percentage, lean meat percentage, cooked meat percentage. |

| Keywords: | genetic distance gene heterozygosities heterosis percentage pigs |
