Abstract: The population inbreeding coefficients of 10 indigenous pig breeds were estimated by microsatellite markers. Results showed that: the inbreeding coefficient of Guizhou miniature pig was the highest (0.1992), and that of Hanzhong black pig the lowest (0.0727) among random mating populations. F test showed no significant difference in inbreeding coefficient among the 8 breeds (P >0.05). The inbreeding coefficient of the Guizhou miniature pig and Bama miniature pig inbreding lines was 0.5907 and 0.4761, respectively.
