大河猪76个STR基因座的遗传多态性

Genetic Diversity of 76 STR Loci in the Dahe Pig

  • 摘要: 大河猪是中国西南中海拔地区代表性猪种之一,长期以来在当地养猪生产中发挥了重要作用。为了阐明其群体遗传变异情况,为进一步有效保护和合理利用提供科学依据,采用分布在家猪19对染色体上的76个微卫星标记对该猪种60个随机抽样个体进行了微卫星PCR–聚丙烯酰胺凝胶电泳检测。共检测到347个等位基因,所有座位都呈现出多态性,每个座位的等位基因数在3—10个之间,平均每个座位等位基因数4.57个,有效等位基因数3.50个,群体平均杂合度及平均多态信息含量分别为0.696 2±0.071 6和0.644 1±0.091 4。结果表明,大河猪群体遗传多样性较丰富,选择潜力较大。

     

    Abstract: The Dahe pig is one of the representative indigenous pig breeds in the middle-altitude region of southwest China, and has played an important role in the local meat production for a long time. In order to estimate the genetic variability in its population, as well as provide the guidance and basis of genetic background for its conservation and further utilization, 76 microsatellite loci situated on swine’s 19 chromosomes were analyzed for 60 individuals sampled from their natural population by employing PCR and polyacrylamide gel electrophoresis. A total of 347 alleles were detected and all the loci were polymorphic. The number of alleles varied from 3 to 10, with a mean allele and effective allele number of 4.57 and 3.50 at each locus respectively. The mean heterozygosity and polymorphism information content of 76 microsatellite loci were 0.696 2±0.071 6 and 0.644 1±0.091 4, respectively. The results indicated that the genetic diversity of the Dahe pig was rich, and the Dahe pig has a good selection potential for breeding.
