Note: ^adenotes the additive effect of a conditional QTL, in absolute values, that reduces or increase less than 10% compared to the corresponding unconditional QTL
^bdenotes the additive effect of a conditional QTL, in absolute values, that reduces more than 10% compared to the corresponding unconditional QTL
^cdenotes the additive effect of a conditional QTL, in absolute values, that increase more than 10% compared to the corresponding unconditional QTL. ^ddenotes the QTL couldn’t be detected in unconditional analysis, but can be detected in conditional analysis
(+) indicates that the most favorable allele is derived from the parent P3228, (−) indicates that the most favorable allele is derived from the parent G8901. E and numerals in parentheses indicate the environment in which the QTL was detected and the percentage of phenotypic variance explained (PVE) by the additive effects of the mapped QTLs, respectively
