Association of single nucleotide polymorphism (SNP) markers in candidate genes and QTL regions with pork quality traits in commercial pigs

► Seven of eight QTL regions for pork quality were confirmed. ► IGF2 was associated with pork color. ► MC4R was associated with pork color, pH and marbling. ► CAST was associated with shear force. ► PRKAG3 was associated pork color, pH, purge and cooking loss.
