$N_{QD}$, number of QTL main effects detected using interval mapping by Tinker et al. (1996); $N_{QV}$, number of main effects validated using Bayesian mapping; $N_{Q\times ED}$, number of Q×E interaction effects detected using interval mapping by Tinker et al. (1996); $N_{Q\times EV}$, number of Q×E interaction effects validated using Bayesian mapping.
