aThe genomic regions shown in bold are the ones with pleiotropic effect
bTraits are plant height (PH) and ear height (EH). The plus (“+”) signs within the brackets indicate Chang 7–2 contributed increasing alleles
cQTL information for the combined analysis
dDegree of dominance: A, additive (|d i */a i *| ≤ 0.20); PD, partial dominance (0.20 < | d i */a i *| < 0.80); D, dominance (0.80 ≤ |d i */a i *| < 1.20); and OD, overdominance (|d i */a i *| ≥ 1.20)
eC Indicates the combined QTL analysis based on the BLUP values across five environments
