Abstract Calpastatin (CAST) is the endogenous inhibitor of calpain system, which has been found to affect the postmortem tenderization of skeletal muscle. Using PCR-RFLP, the polymorphism of CAST gene in five pig populations (total of 110 pigs), were analysed, and the relationship between the CAST genotypes and pork quality and backfat was evaluated. The results showed that there were 4 polymorphism sites (A, B, C and D) in CAST gene which presented a significant differences in the five populations. In A and B sites, the genotype effects were significant on pork tenderness only(P<0.05); the gene additive effects were significant (P <0.05) but the dominant effects were not. In C site, the genotype effects were not significant on all the traits analysed(P >0.05). In D site, the genotype effects were significant on backfat only(P <0.05); the gene dominant effects were significant(P <0.05), but the additive effects were not. It is concluded that CAST gene can be used as a candidate gene for pork quality and carcass quality traits.
