利用SSR技术分析福建省家鸭地方良种金定鸭、山麻鸭、连城白鸭和野鸭绿头鸭、斑嘴鸭基因组DNA的多态性，在21个位点共扩增得到421条带，其中多态性条带213条，约占总数的50．6％．多态性位点比率在33．3％～84．6％之间．运用简单匹配系数法计算了品种（系）间的相似性系数和遗传距离，家鸭品种间的遗传距离在0．043～0．251范围内，绿头鸭、斑嘴鸭与家鸭品种（系）间的遗传距离分别在0．203（金定鸭Ⅰ系）～0．232（金定鸭Ⅱ系）和0．236（山麻鸭）～0．317（金定鸭Ⅱ系）范围内．连城白鸭与金定鸭3个品系间的遗传距离介于0．232至0．251之间，山麻鸭与金定鸭3品系间的遗传距离在0．239至0．248范围内．而连城白鸭与山麻鸭间的遗传距离为0．136．

Simple sequence repeat technique was used to estimate the genomic DNA polymorphism among three famous endemic breeds of domestic ducks （Jinding duck, Lianchen white duck,Longyan Shanma duck）and two species of wild duck（ Anas Platyrhyncho,and Anas Poecilorhyncha ） in Fujian province. 21 SSR primer pairs detected a total of 421 fragments. Two hundred and thirteen bands, representing 50.6 % of total fragments, were polymorphic. The proportion of polymorphic loci ranged from 33. 3%%to 84. 6%. Simple matching coefficients （SM）was calculated to manifest the genetic similarity and distance. The genetic distance between domestic ducks was 0. 043～0. 251 ,while between domestic ducks and the wild ducks was 0. 203～ 0. 232（ Arms Platyrhynchos ） and 0. 236～0. 317 （Arms Poecilorhyncha ） respectively. The distances range from 0. 232 to 0.251 between Lianchen white duck and three strains of Jinding duck,while range from 0. 239 to 0. 248 between Shanma duck and the 3 ones. The genetic distance between Lianchen duck and Shanma duck is 0. 136.
