aGenetic position of each QTL was estimated by multiple interval mapping. bPositive (+) means that parental digenic genotypes increase trait expression and negative (-) means that the recombinant alleles from both parents increase trait expression. cPercentage of phenotypic variance explained by individual epistatic effects of the mapped QTL.
