The aim of this study is to investigate the genetic interrelationships between economic or meat quality traits (birth weight, weaning weight, average daily gain, market weight, carcass weight, backfat thickness, water, ash, fat, protein, water holding capacity and pH) and 6 SNPs located on six selected candidate genes (MC4R, PGK2, TNNI1, TNNI2, PIK3C3, and CTSK) in Korean native pigs. The genotypes were identified in the 6 SNPs by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) procedure, and association of the genotype on economically important traits was analyzed by general liner model. According to the analyzed results, the MC4R c.1426A>G was correlated with birth weight (p=0.032) and the PGK2 g.122T>G was associated with pH (p=0.026). These findings obtained in the present revealed that the each SNPs of MC4R and PGK2 could be useful as potential genetic markers for birth weight and pH in Korean native pigs, respectively.
