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.
