摘要: 为了探究我国灰鹅品种的遗传多样性和系统进化,运用DNA测序技术测定了我国13个灰鹅品种mtDNA D-loop区521 bp序列。结果表明:这13个灰鹅品种521 bp D-loop区序列的T、C、A和G碱基含量分别为23.8%、29.0%、32.3%和15.0%;平均单倍型多样度和核苷酸多样度分别为0.19245和0.00036;13个灰鹅种间变异大于种内变异,且均未出现群体扩张现象;共享单倍型和系统进化树分析表明,伊犁鹅起源于灰雁(Anser anser),其余12个灰鹅品种起源于鸿雁(A. cygnoides)。

Abstract: In order to reveal the genetic diversity and systematic evolution of Chinese greylag goose breeds, the 521 bp control region (D-loop) of mitochondrial DNA from 13 greylag goose breeds were sequenced. In the D-loop, the contents of T, C, A, and G nucleotides occupied 23.8%, 29.0%, 32.3%, and 15.0%, and the average haplotype diversity (Hd) and nucleotide diversity (Pi) were 0.19245 and 0.00036, respectively. The nucleotide variance value among the populations was bigger than that within the populations, and no population expansion was observed for the breeds. The shared haplotype analysis and systemic evolution analysis revealed that the 13 breeds had two maternal origins, among which, Yili breed originated from greylag goose (Anser anser), and the other 12 breeds originated from swan goose (A. cygnoides).
