  1. For each trait is described, the linkage group (LG) where the QTL was identified, position on the map, name of the closest locus to the logarithm of the odds (LOD) peak, LOD value, LOD threshold on the linkage group and on the whole genome with α = 0.05%, confidence interval, phenotypic variance explained by the QTL (R2), global variance explained by all the QTLs detected for one trait (Global R2), and significant degree according to non-parametric Kruskal-Wallis test (KM)
