Summary Linkage and QTL maps of Sus scrofa chromosome 9 (SSC9) were constructed using 16 markers, with 13 to 15 used in three F 2 families based on Wild Boar (W), Meishan (M) and Pietrain (P) crosses. The LPR and SLN loci were integrated into the linkage map of SSC9 for the first time. Only a few quantitative trait loci (QTLs), explaining up to 5.1% of the F 2 phenotypic variance, were identified on SSC9 with chromosome‐wide significant effects on growth and fattening in the W × P family and on weight of liver, growth and fat‐to‐meat ratio in the W × M family. No QTLs were found in the M × P family. Gene effects were mainly dominant in the W × P family. In the W × M family, Wild Boar QTL alleles for weight of liver were superior over Meishan alleles.
