Abstract: The sequence of extron 4 of the porcine SGCB gene was obtained from Large White, Landrace and Meishan pigs. Sequence comparison revealed a A/G mutation which was detected by ARMS-PCR. The A and G alleles were balanced in the Large White, Landrace, Meishan pigs and Large White×Meishan F2 population. Association analysis between the polymorphism and carcass traits was performed in Large White×Meishan F2 population with 266 pigs. The genotype AA had significant effect on average lean meat percentage(P<0.01), the genotype GG had significant effect on loin-muscle height(P<0.01) in Large White×Meishan F2 population.
