中国的鸭类遗传资源特别丰富。为了揭示中国家鸭的遗传多样性和起源，对26个地方品种238只家鸭、25只野鸭和9只斑嘴鸭的线粒体DNA控制区667 bp进行了序列测定，并结合已发表的12只野鸭和9只斑嘴鸭的数据进行了分析。单倍型多样性（Hd，0.645）和平均核苷酸多样性（Pi，0.115%）表明中国家鸭的遗传多样性较低。利用72个单倍型构建NJ系统发育树和简化中位连接网络图。野鸭（Anus platyrhynchos）的遗传贡献在大多数地方鸭种中都可以检测到，而斑嘴鸭（Anus zonorhyncha）的遗传贡献在少数地方鸭种中也可以检测到。结果表明，中国家鸭主要是野鸭（A. platyrhynchos），少数来源于斑嘴鸭（A. zonorhyncha）。(C)2010年爱思唯尔公司All rights reserved.
China is particularly rich in duck genetic resources. In order to reveal the genetic diversity and origin of Chinese domestic duck, the 667 bp control region of mitochondrial DNA of 238 domestic ducks from 26 indigenous breeds, 25 wild mallards and nine spot-billed ducks were sequenced and analyzed them together with the published data for 12 mallards and nine spot-billed ducks. The haplotype diversity (Hd, 0.645) and average nucleotide diversity (Pi, 0.115%) indicate low genetic diversity of Chinese domestic ducks. The NJ phylogenetic tree and reduced median-joining network chart were constructed using a total of 72 haplotypes. The genetic contribution of mallard (Anus platyrhynchos) can be detected in most of Chinese indigenous duck breeds and that of spot-billed duck (Anus zonorhyncha) can also be detected in few Chinese indigenous duck breeds. The results indicated that the Chinese domestic ducks mainly derived from mallard (A. platyrhynchos) and few derived from spot-billed duck (A. zonorhyncha). (C) 2010 Elsevier Inc. All rights reserved.
