  1. QTL, quantitative trait loci identified for each phenotype, see Table 1 for phenotype description; Chr, chromosome to which the QTL maps; Start, position (bp) on the chromosome where the QTL starts; End, position (bp) on the chromosome where the QTL ends; Peak position, position (bp) on the chromosome where the peak SNP is localized; peak SNP is the marker with the most significant association in terms of P-value for each QTL; the nearest gene is reported based on the peak SNP position; MAF, minor allele frequency for the SNP at the peak position, in the breed that is relevant to the QTL
