摘　　要：对八眉猪、内江猪、荣昌猪、汉江黑猪等西部地区地方品种和汉中白猪、长白猪、大白猪、杜洛克猪等 8个猪品种以及野猪基因组 DNA、混合 DNA样进行了 RAPD分析。根据 8个多态引物的扩增结果计算了遗传距离指数并进行了 UPMGA聚类分析。结果表明 :长白猪与大白猪亲缘关系最近 ,八眉猪和汉江黑猪次之 ,而野猪与长白猪的遗传距离最远。综合考虑现行的分类结果及前人研究结果 ,认为内江猪、八眉猪和汉江黑猪为一类型 ,荣昌猪和汉中白猪可划分为同一类型 。Random amplified polymorphic DNAs(RAPDs)were used to investigate bulked genomic DNA polymorphism of 8 pig breeds and wild pig in west China including Duroc,Landrance,Largewhite,Neijiang pig,Rongchang pig,Hanjiang Black pig,Hanzhong White pig,Bamei pig and wild pig.The genetic distance index matrix and UPMGA phylogenetic trees generated from 8 polymorphic primer amplified results showed that the genetic relationship between Landrance and Largewhite was the closest,while that between wild pig and Largewhite was the farthest.It was inferred from this study that Neijiang pig,Bamei pig and Hanjiang Black pig could be classified into one type,as the same to Rongchang pig and Hanzhong White pig.However,the population genetic character of wild pig should be further evaluated.
