摘  要：
【目的】了解中国部分地方鸭品种的群体遗传结构和遗传分化.【方法】使用荧光标记的微卫星引物和ABI-3730XL型DNA测序仪器,对我国6个地方鸭品种(180只)在16个微卫星位点上的等位基因进行STR分型测序,利用Structure和Fstat软件对群体结构和遗传分化进行分析.【结果】16个微卫星位点共检测到141个等位基因,具有高度多态性;F-统计量结果显示群体间存在显著的遗传分化;Structure程序成功构建出了6个鸭品种的遗传分化结构图;Structure程序构建的Neighbor Joining(NJ)图将‘润州凤头白鸭’‘于田麻鸭’聚为一类,‘北京鸭’与‘樱桃谷鸭’‘吉安红毛鸭’聚为一类.【结论】通过16个多态性较好的微卫星位点对中国6个地方鸭品种进行了遗传结构性和遗传分化研究,为获取我国地方鸭品种间的遗传信息和遗传关系提供更准确的依据.

摘  要：
【Objective】 To understand the genetic structure and genetic differentiation of local duck species in China.【Method】 In this study,the fluorescent-labeled microsatellite primers were used for STR typing of alleles in 16 microsatellite loci in 6 duck cultivars(180 heads) preserved in China by ABI-3730 XL DNA sequencing platform.Population structure and genetic differentiation were analyzed using Structure and Fstat software.【Result】 A total of 141 alleles were detected in 16 microsatellite loci with high polymorphism.The F-statistics showed significant genetic differentiation among populations.The Structure program successfully constructed the genetic differentiation structure of 6 duck breeds.The Neighbor Joining(NJ) map constructed by the Structure program showed that ‘Runzhou White Crested Duck' and ‘Yutian Ma Duck' were clustered together,and ‘Beijing Duck'‘Cherry Valley Duck' and ‘Ji'an Red-haired Duck' were clustered together.【Conclusion】 In this study,16 microsatellite loci with abundant polymorphism were used to study the genetic structure and genetic differentiation of 6 local ducks in China,which provided more accurate basis for obtaining the genetic information and genetic relationship among local ducks in China.
