Overview of epistatic interactions identified in reconstructed F₂ population and three environments for 15 yield-correlated traits.

§For the abbreviation of the traits (ordered according to their correlation coefficients with SY), see MATERIALS AND METHODS. *Epistatic interactions between (SS) two loci with significant main-effects, (SN/NS) a locus with significant main-effect and a locus with non-significant main-effect, and (NN) two loci with non-significant main-effects. †M-QTL and E-QTL are the abbreviations for main-effect QTL and epistatic QTL respectively.
