Abstract: Carcass traits and meat quality traits of Hainan Pigs,Black Pigs ( Hainan Pigs♀×Duroc♂) were measured,and the genetic variation of H-FABP and MyoG 5’ upstream sequence of Hainan Pigs were analyzed. The results indicated that the live weight,carcass weight,dressing percentage,carcass length and lean yield of Black Pigs were higher than that of Hainan Pigs (P < 0.05),bone percentages,skin percentages were lower than that of Hainan Pigs,fat deposition capability was higher than that of Hainan Pigs,and the changes of loin eye area and skin thickness were not significant. The meat quality of Hainan Pigs and Black Pigs attained fine meat quality criteria,drip loss,marbling,moisture,crude protein concentration of Black Pigs were superior to that of Hainan Pigs. The gentype and gene frequency of genetic variation of H-FABP and MyoG 5’ upstream sequence of Hainan Pigs set an important genetic basis for the formation of fine meat quality traits of Hainan Pigs.
