摘要
对我国 7个地方猪品种 (二花脸、通城、清平、阳新、皖南花、赣东黑、万安 )和 3个引进品种 (长白、大白、杜洛克 )的 4个微卫星位点的多态性进行了检测 ,并对品种内和品种间的遗传变异进行了群体遗传学分析。结果初步表明 ,地方品种中二花脸、赣东黑、通城的品种内遗传变异较高 ,万安的品种内遗传变异最低。除万安猪外 ,其它地方品种的品种内变异均大于引进品种。品种间的聚类结果基本符合品种的地缘分布。
The polymorphism of four microsatellites has been investigated in seven Chinese indigenous pig beeds(Erhualian,Tongcheng,Qingping,Yangxin,Wannanhua,Gandonghei,Wanan) and three introduced breeds(Large White,Landrace,Duroc) in China,and the genetic diversity within and among populations is analyzed The results showd that Erhualian,Gandonghei,Tongcheng have higher within-breed variation,while Wanan has the lowest variation Within-breed variation of Chinese indigenous pig breeds except Wanan is higher than that of the introduced pig breeds The clustering of ten breeds is consistent with their geographical distribution
