摘要/Abstract

摘要： 旨在从mtDNA水平探讨我国家鸭的遗传多样性及家鸭与野鸭间的亲缘关系。运用DNA测序方法，测定了不同地域、水域和表型性状的9种家鸭（北京鸭、高邮鸭、巢湖鸭、绍兴鸭、连城白鸭、吉安红毛鸭、文登黑鸭、云南麻鸭、建昌鸭）80个个体、4 种媒鸭（西湖野鸭、钱江野鸭、枞阳媒鸭、媒头鸭）26个个体和斑嘴鸭8个个体，共计114个个体的mtDNA Dloop区 667 bp序列。9种家鸭单倍型多样度和核苷酸多样度分别为0.250 00~0.607 14 和0.000 38~0.001 18； 9种家鸭、媒鸭、绿头鸭和斑嘴鸭之间的遗传距离为0.001~0.015；39种单倍型系统发生树和单倍型网络关系图表明，9种家鸭主要属于A1亚簇（绿头鸭单倍型簇）。我国家鸭遗传多样性中等丰富，母系起源主要是绿头鸭，极少量个体含有斑嘴鸭血统。

Abstract: The research was aimed to study the genetic diversity of the domestic duck breeds and the relationship with the wild duck. The 667 bp control region (D-loop) of mitochondrial DNA of 9 different phenotypic domestic duck breeds from different regions and rivers, 26 individual Mei ducks and eight spotbilled ducks (Anas zonorhyncha) were sequenced. The haplotype diversity (Hd) and nucleotide diversity (Pi) of domestic ducks were 0.250 00-0.607 14 and 0.000 38-0.001 18, respectively. 39 haplotypes were used in the phylogenetic analysis, and the results showed that almost 9 domestic duck breeds originated from mallard (Anas platyrhynchos). The genetic diversity of Chinese ducks was middle rich. The most maternal pedigree of mallard (Anas platyrhynchos) and only a little pedigree of spotbilled ducks (Anas zonorhyncha) contributed to the origin of domestic ducks.
