摘　　要：为了阐明红色原鸡的群体遗传结构,以对其有效保护提供遗传学依据,采用33个微卫星标记对其群体中56个个体进行了PCR-聚丙烯酰胺多态性电泳检测。33个微卫星座位共检测到140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2～8个之间,平均每个座位等位基因数4.24个,有效等位基因数3.30个。根据等位基因频率,计算出的群体表观杂合度、期望杂合度及多态信息含量分别为0.7980、0.6506和0.5948。结果表明,红色原鸡群体遗传多样性较丰富。In order to assess the genetic diversity in the population of Red Jungle Fowl in Yunnan Province and provide genetic basis for its conservation and utilization, 33 chicken-specific mierosatellite loci were assayed in 56 individuals by using polyaerylamide gel eleetrophoresis. A total of 140 alleles were detected in the 33 loci. All the loci were polymorphie and the number of alleles varied from 2 to 8, with a mean number of 4.24 alleles and 3.30 effective alleles per locus. The observed heterozygosity, expected heterozygosity and polymorphism information content of 33 mierosatellite loci were 0.798 0, 0.650 6 and 0.594 8, respectively. Our data indicate that there is high genetic diversity in natural population of Red Jungle Fowl.
