| 摘 要： | 通过资源调查摸清我国长江中下游地区6个鹅品种的保存现状，同时结合微卫星标记对种群结构和动态进行了检测。结果显示，6个鹅品种均处于正常保种状态； 群体平均杂合度最高的是太湖鹅（0.690），最低的是武冈铜鹅（0.567），各鹅种的平均杂合度为0.640。用UPGMA法进行聚类分析，将6个鹅品种聚为3类，四川白鹅、武冈铜鹅、道州灰鹅、酃县白鹅聚为第1类；溆浦鹅为第2类；太湖鹅为第3类。根据资源调查及分子研究结果提出了保种意见。

| Abstract: | Thirty-one microsatellite markers and resources investigation were used to analyze the conservation status of 6 geese breeds in different conservation farms along middle-lower reaches of the Yangtze River.Dynamic genetic analysis and genetic structure were estimated by microsatellite loci.The results suggested that all 6 geese breeds were in normal conservation status;The average heterozygosity was 0.640,Taihu scored the highest(0.690) and Wugang Tong goose was the lowest(0.567).The topology of phylogenetic tree constructed showed general patterns of genetic relationships among the populations studied.The six breeds were classified into three major groups.Four geese populations,White Sichuan,Wugang Tong,Grey Daozhou and White Lingxian were grouped into one branch.Xupu grouped by itself,as well as Taihu.Our findings can be used as genetic information for the preservation of the Chinese geese breeds. We also put forward conservation suggestions according to resources research and microsatellite analysis. |
