摘要：
Chinese domestic pig breeds have abundant genetic resources, but definite information about the geogra-phic specificity and genetic structure is lacking. In this study, we analysed 359 mitochondrial D-loop sequ-ences, including 86 sequences from Chinese domestic pigs and the rest downloaded from GenBank. The haplotype and nucleotide diversity indices ranged from 0.467 +/- 0.132 (Duroc) to 1.000 +/- 0.500 (Thailand, North Korea and Cambodia) and 0.00067 +/- 0.00019 (Duroc) to 0.02000 +/- 0.01000 (Thailand), respectively. The neighbour-joining tree revealed two clads in the individual pigs, with a Chinese domestic breed distri-buted discontinuously among several breeds. The network data indicated that the gene pools of Chinese domestic pigs are likely related to Chinese, Japanese and some other Southeast Asian wild boars.
