^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
^fHeterosis-associated QTLs reported in previous studies: 1 Ku et al. [43]; 2 Wen et al. [48]; 3 Yang et al. [45]; 4 Wang et al. [18]; 5 Frascaroli et al. [46]; 6 Song et al [22]; 7 Frascaroli et al. [23]; 8 Li et al. [16]
