| 摘要: |
| 以血清蛋白质和酶多态位点作为遗传标记，通过检测八眉猪四大产区六个亚群的遗传组成，对八眉猪群体内的遗传变异进行了分析和探讨。结果表明，八眉猪亚群间在个别位点上有较大分化，主要是Po和Hp位点；八眉猪亚群间遗传变异占其总群体的4.15％，八眉猪群体内的遗传变异占我国部分地方猪种（或群体）总和的10.84％；亚群间的亲缘关系以L和Ch亚群最近，与HD亚群最远；亚群间的分化具有一定的层次，即主要是中心产区与一般产区的分化。 |

| Abstract: |
| The genetic Differentiation was examined and analysed of 6 sub-populations from four areas of Bamei pig distribution through monitoring the genetic strimture with serum polymorphic loci as genetic markers. The result showed that there was a significant differentiation in certain locus among the sub-populations, mainly appearing in Po and Hp loci.The genetic variation among the sub-populations accounted for 4.15% of the total genetic variation of Bamei, and the genetic variation within Bamei was 10.84% of the total genetic variation of some Chinese native pig breeds.The results also indicated that the genetic relationship between L and Ch sub-population was the cloest,and Hd sub-population was situated at a long distance from the other, and the differentiation betvveen the central and the ordinary area of the breed distribution could account for the demarcation of local type population. |
