Meat quality is one important selection criterium to consumers. In Asian countries, demands for native chicken breeds with better meat quality-related traits are increasing. In this study, 13 meat quality related traits in Korean native chicken were collected to identify QTLs that could affect the traits. A total of 20 novel QTLs, including 6 for general meat compounds (GC), 7 for the meat color (MC), and 7 for pH were identified. Significant QTLs (i.e., 1% chromosome wide significance) for crude protein contents in thigh and breast muscles were identified. Other QTLs were also identified with suggestive significance levels (i.e., 5% level of chromosome wide significance). Results presented here could provide useful information to find causal variants to improve meat quality traits in chicken.
