摘要
对中国 4个地方猪品种 (二花脸、通城、清平、皖南花 )和 3个引进品种 (长白、大白、杜洛克 )的 6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。初步结果表明 ,地方猪品种的群体内变异均大于引进品种 ,其中二花脸的品种内变异最高。品种间的聚类结果表明 ,地方品种与引进品种间具有较远的亲缘关系 。
The polymorphism of six micro satellites was investigated in four Chinese indigenous pig breeds(Erhualian,Wannanhua,Qingping,Tongcheng)and three introduced breeds(Large White,Landrace,Duroc)in China,and the genetic diversity within and among population was also analyzed The results showed that Chinese indigenous pig breeds had the higher within breed variation than the introduced ones Erhualian has the higher within breed variation The clustering of seven breeds suggested that indigenous breeds have close relationship,but the result was not completely consistent with the result of phenotypic classification for indigenous pig breeds
