Abstract
SummaryLinkage and QTL maps of Sus scrofa chromosome 9 (SSC9) were constructed using 16 markers, with 13 to 15 used in three F2 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 F2 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.
