* indicates p < 0.05; ** indicates p < 0.01. a epistatic effects, a positive value indicates that the parental two-locus genotypes have a positive effect and that the recombinants have a negative effect. b phenotypic variance explained by epistatic QTL pair. c epistatic QTL pairs by environment interaction effects. AE1 indicates 2012JP; AE2 indicates 2014JP; AE3 indicates 2014YC. d phenotypic variance explained by epistatic QTL pairs with environment interaction effect.
