The results showed that the average heterozygosity was higher in 9 populations,the lowest is Jinding, the highest is San sheldrake, which ranged from 0.5137~0.6055. The average heterozygosity of 9 duck populations was 0.5523, which reflected the rich diversity. Considerable breed differentiation was observed and 25.65% of the total genetic variation came from breed differences, this result affirmed each breed was of own genetic diversity. The DA genetic distances suggested the longer differentiation existed between those breeds. The domestic duck breeds in East China were clustered into four groups based on the NJ clustering, the clustering results had some relationship with the distributions and economic utilizations of these duck breeds.

结果表明：9个品种的平均杂合度都较高，最低的为金定鸭，最高的为山麻鸭，杂合度范围为0.5137～0.6055，群体平均杂合度为0.5523，反映了各鸭种的杂合度都较高，遗传多样性丰富；华东区各鸭种间存在较大的遗传分化，25.65%的遗传变异来源于品种间的差异，更进一步反映了各品种具有本品种特征特性的多样性；通过计算DA遗传距离发现各群体的遗传距离较远，分化时间较长；NJ聚类结果将华东区家鸭资源聚为4类，NJ的聚类结果分析与几个鸭品种的地域分布和经济用途有一定关系。
