  1. aBin locations were designed by an X.Y code, where X was the linkage group containing the bin and Y was the location of the bin within the linkage group [53]
  2. bDS was the estimation for the complete data set; ES was the average value for the 1000 estimation sets; TS was the average value of the 1000 validation sets in cross validation; the bias was calculated as the difference between ES and TS estimations divided by the ES estimation
  3. cAdditive effect of the QTL estimated as half the difference between the genotypic values of the two homozygotes. A positive estimation means that EP42 carried the allele with higher value
