Summary For Sus scrofa chromosome 13 (SSC13) eleven markers were genotyped to generate linkage and QTL maps in three F 2 families based on Wild Boar (W), Meishan (M) and Pietrain (P) crosses. Results of linkage maps were similar and agreed with published maps. Quantitative trait loci (QTLs) for body weights, meat conductivity and fat deposition were mapped in the M × P family to the interval S0076–S0068 (40–80 cM) and near the locus SW38 (120–150 cM). QTLs for the same traits were observed in the W × M family in different intervals explaining up to 5.3% of the F 2 phenotypic variance. No significant QTLs for the traits under investigation were found in the W × P family. The effects of QTL alleles were mostly dominant. In the M × P and W × M families alleles inherited from Meishan were generally associated with high values of live weights, food consumption and fat deposition and low values of meat conductivity.
