Linkage maps of Sus scrofa chromosome 8 (SSC8) were constructed using seven markers in three F2 families based on Meishan (M), Pietrain (P) and Wild Boar (W) crosses. The maps were similar for the pedigrees and in agreement with published maps. Most quantitative trait loci (QTLs) were found for the W · P family, while only minor QTLs were detected in the M · P and W · M families. SSC8 harbours QTLs mapped in the interval SW905 to SW933 explaining up to 6% of the F2 phenotypic variance for body conformation, carcass and growth traits. Pietrain alleles positively influenced carcass traits, with additive effects often larger than dominance effects. For food conversion ratio a large dominance QTL effect was observed in the M · P family.
