Abstract
Chinese domestic pig breeds have abundant genetic resources, but definite information about the geographic specificity and genetic structure is lacking. In this study, we analysed 359 mitochondrial D-loop sequences, 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 distributed 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.
