| Abstract: | 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 305 F2 individuals from a commercial slaughter pig cross in Norway. F1 and F2 individuals were genotyped for 29 markers on Chromosomes (Chrs) 4, 6, and 7, since previous studies had revealed QTL affecting
meat quality traits on these chromosomes. The most evident result was detection of a QTL affecting amount of intramuscular
fat on Chr 6. The QTL might also influence tenderness, whereas no effect was observed for back-fat thickness. Additionally,
suggestive evidence for QTL affecting other meat quality traits was found on Chr 4 and Chr 7.
