摘    要:本研究通过10个微卫星位点对我国特有的4个小型猪种(五指山猪、滇南小耳猪、贵州小型香猪、巴马香猪)进行了遗传学检测,结果表明:除S0003位点表现为单态外,其它9个位点均为高度或中度多态位点;4个小型猪种群体内的遗传多样性比较高,平均基因杂合度分别为0.7165,0.6611,0.6602,0.5990;多态信息含量在0.5774-0.6871之间;五指山猪与贵州小型香猪的遗传距离较近,与滇南小耳猪次之,它们与巴马香猪都较远。

关 键 词:微卫星标记  中国  小型猪  遗传多样性

Abstract:The study was on the Chinese four miniature pigs by using ten micro satellite loci.The result was showed that:9 of the 10 microsatellite loci were medium or high polymorphism,but S0003 was single.The genetic diversity in the four populations was higher,and the average genetic heterozygosity was 0 7165,0 6611,0 6602,0 5990,respectively.The average polymorphism information content was between 0 5774 and 0 6871.The genetic distance between Wuzhishan Pig and Guizhou Miniature Xiang Pig is the nearest and between Wuzhishan and Diannan Xiaoer is nearer.They are all far from Bama Xiang Pig.
Keywords:Microsatellite  Miniature pig  Genetic diversity
