摘　　要：采用ESTMS20,SW2570和S0002等3个微卫星标记对长白猪进行了遗传多样性的研究。结果发现,3个卫星标记在长白猪中均具有多态性,遗传杂合度分别为0.69,0.70和0.41,多态信息含量分别为0.64,0.68和0.38。以上结果表明,这3个微卫星标记在长白猪群体中属于高度多态性座位,可以用于长白猪遗传多样性的评估。In this study, allele frequency, number of effective alleles, heterozygosity and polymorphism informa- tion contents of three microsatellite markers （ESTMS20, SW2570 and S0002）were analyzed in Landraee. The results indicated that three microsatellite markers had genetic diversity in Landrace. The heterozygosity and the polymorphism information contents of ESTMS20, SW2570 and S0002 was 0.69,0.70 and 0.41, and 0.64, 0.68 and 0.38, respectively ,which suggested that the microsatellites ESTMS20, SW2570 and S0002 belonged to highly polymorphic seat and could be used for genetic diversity evaluation in Landrace.
