aQTL name composed by the trait code followed by the chromosome number in which the QTL was mapped and the physical position of the flanking markers in Mb. Chr, chromosome; LOD, logarithm of odds; Add, additive effect; Dom, dominance effect; PVE, phenotypic variance explained. Markers with bold letters are the QTL consistent across at least two populations. The marker name indicates the chromosome number followed by its physical position; for example, S6_68207704 denotes that the marker is in chromosome 6 at a position of 68,207,704 bp (Ref Gen_v2 of B73). CI, confidence interval.
