^aGenetic position in centimorgans (cM) of QTL with the highest LOD; ^bPhysical position of QTL based on the B73 reference sequence (v2); ^cAdditive effect of QTL: a positive value means the allele from the parent Mo17 increases the index of traits, whereas a negative value indicates that the allele from teosinte decrease the index of traits; ^d Percentage of the phenotypic variation explained by the additive effect of QTL
