摘　　要：利用9个微卫星标记分析了高邮鸭群体遗传多样性。结果9个微卫星座位共检出42个等位基因,基因频率分布在0.0135～0.6216之间,平均每对引物可检测4.7个等位基因,9个微卫星座位的平均杂合度为0.7375,平均多态性含量为0.6707,表明高邮鸭群体遗传变异大,遗传多样性丰富。Genetic diversity of Gaoyou Duck was assayed with 9 microsatellite DNA markers.The results showed that there were 42 alleles inspected in 9 microsatellite loci.Allele frequencies were 0.0135-0.6216,the average number of alleles was 4.7.The mean heterozygosity of the Gaoyou Duck was 0.7375.The average value of polymorphism information content （PIC）was 0.6707. There were high genetic diversity and rich polymorphism in Gaoyou Duck population.
