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。
The genetic Differentiation was examined and analysed of 6 sub-popula-tions from four areas of Bamei pig distribution through monitoring the genetic strimturewith serum polymorphic loci as genetic markers. The result showed that there was asignificant differentiation in certain locus among the sub -populations, mainly appearingin 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 was10.84%of the total genetic variation of some Chinese native pig breeds.The results al-so indicated that the genetic relationship between L and Ch sub-population was thecloest,and Hd sub-population was situated at a long distance from the other, and thedifferentiation betvveen the central and the ordinary area of the breed distribution couldaccount for the demarcation of local type population.
