^aName given to a particular QTL, GLY and TOT for glycitein and total isoflavone content, respectively, followed by the chromosome number and a number when more than one in the same chromosome. Asterisks highlight QTL reported in our previous study [14]. ^bInterval of confidence in centiMorgans with respect to the first marker in the LG. ^cMain additive effect in μg/g plus/minus standard error. Mean effect of substituting both Essex alleles by PI437654 alleles. Thus, positive values indicate that the PI437654 allele increase the phenotypic value^{. d}F-values of significance of each QTL. Threshold F-values were 7.2 and 8.0 for glycitein and total isoflavones, respectively, for the 4-environmentcombined analysis. Between brackets is the threshold F-value for QTLs identified at a particular environment. P-values represent the significance of each effect. ^eh²(a) is the heritability of the additive effect or percentage of variation (%) that is explained by the additive component of the QTL.
