QTL were named using R/qtl nomenclature, i.e., linkage group@position (cM). Linkage group numbers 1–19 correspond to chromosome numbers in the female map (‘Horizon’), and 20–38 correspond to chromosome numbers 1–19 in the male map (Illinois 547-1)
: Indicates an interaction term between two QTL
aPVE, percentage of variance explained by the model
bQTL that were significant only on one date of evaluation
