and 
are the maternal effect, embryo additive effect, embryo dominance effect of QTL and their interaction effects with the first and the second environment, respectively. - ** And * indicate reaching significance at level of 0.01 and 0.05, respectively.
- aResult from the model with QTL effect and QTL-by-environment (QE) interaction effect.
- bResult from the model with exclusion of QE interaction effects.
