摘　　要：利用微卫星标记估计了中国10个地方猪种的群体近交系数。结果表明:在随机交配群体中,贵州小型香猪的近交系数最高为0.1992,汉中黑猪的近交系数最低为0.0727。F检验表明,品种间近交系数的差异不显著(P>0.05)。在近交群体中,贵州小型香猪近交系和巴马香猪近交系的近交系数分别为0.5907和0.4761。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.
