Abstract: The two genes EPOR and MYPN, were analyzed by SNP genotyping and associated with meat quality traits to find the candidate genes for meat quality traits. The methods for SNPs genotyping are PCR-SSCP and PCR-RFLP. No SNP were found for EPOR genes. Two SNPs were found in MYPN genes and the two genes were associated with meat quality traits by SAS. The results showed that SNP1 had significant effects on back fat thickness, conductivity, eye muscle area, intramuscular fat (P＜0.05); SNP2 had significant effects on back fat thickness and intramuscular fat (P＜0.05）；sex and breed had significant effects on some traits (P＜0.05). Combined results of this study and other related research findings, it may be inferred that the MYPN gene may affect the meat quality traits and carcass traits, or the major gene and control of these traits in the main chain gene can be used as meat quality carcass traits of the candidate genes.
