The primary goal of this study was to localize quantitative trait loci (QTL)affecting meat quality traits in swine. In total, 42 traits were scored on 305F2 individuals from a commercial slaughter pig cross in Norway. F1 and F2individuals were genotyped for 29 markers on Chromosomes (Chrs) 4, 6, and 7,since previous studies had revealed QTL affecting meat quality traits on thesechromosomes. The most evident result was detection of a QTL affecting amount ofintramuscular fat on Chr 6. The QTL might also influence tenderness, whereas noeffect was observed for back-fat thickness. Additionally, suggestive evidencefor QTL affecting other meat quality traits was found on Chr 4 and Chr 7.
