Significant QTL regions identified in the merged dataset or in the merged dataset and individual backcross GWAS.

Results for body weight at 150 days (BW150), backfat thickness at slaughter (BFTS), ham (HW), shoulder (SH), loin bone-in (LBW) mean weights and intramuscular fat (IMF): region name, dataset, genomic position, number of associated SNPs, associated trait, additive effects and P-value. The effect was estimated on the most significant SNP of each QTL region.
