摘要
选用12个微卫星标记对5个鸭群体（金陵黑鸭、樱桃谷鸭、乌嘴鸭、莆田黑鸭和三穗鸭）的进行了了群体内杂合度、多态信息含量和群体间遗传距离进行检测和分析。结果表明，12个微卫星标记只有7个在5个群体中检测到多态性，5个群体的平均杂合度在0．5308-0．6347之间，其中金陵黑鸭的平均杂合度最高，乌嘴鸭的最低。基于Nei氏标准遗传距离构建的系统发生树结果表明，樱桃谷鸭独聚为一大类，金陵黑鸭与乌嘴鸭聚集为一类，莆田黑鸭和三穗鸭聚集为一类。上述5个群体7个微卫星座位的检测和分析结果为这些鸭群体的资源利用提供了参考依据。
Locus heterozygosity, polymorphism information cotents and genetic distance were studied in five populations（Jinling duck, Cherry duck, Wuzui duck, Putian duck and Sansui duck）. The result indicated there are genetic polymorphism at seven microsatellite markers in five duck populations. The average heterozygosity of seven microsatellite markers in five populations are 0. 530 8 to 0. 634 7. The average heterozygosity in Jinling duck is highest, and lowest in Wuzui duck. The dendrograms which were constructed based on Nei＇s standard genetic distance showed： Cherry duck were alone clustered one type. Jinling duck and Wuzui duck were clustered together. Putian duck and Sansui duck were clustered another type. The results of analysis of seven microsateUite markers in five populations established a basis for utilizing these breed resource.
