1The test is either ‘QTL-QTL,’ which identifies epistatic interactions between main-effect QTLs (Figure 1, unboxed numbers; Table 1), or ‘QTL-other,’ which identifies epistatic interactions between QT
Epistasis strongly affects the performance of superior maize hybrids. In this study, a multiple-hybrid population, consisting of three hybrid maize sets with varied interparental divergence, was gener
