L and H: low (0.1) and high (0.4) heritability traits, respectively.
Chr: chromosome; WG: Whole genome.
wGBLUP: weighted GBLUP.
Different alphabets mean significantly different values at a type one error rate of 0.05 with Bonferroni correction. Subscripts and superscripts stand for comparisons within column and row, respectively, for each trait.
