TABLE 2.

Mean genotypic values and gain per cycle of the 20 genotypes selected under MESIM and the Lande–Thompson 1 (economic weights are 1s and −1s) and Lande–Thompson 2 (economic weights are heritability of the traits) molecular selection index for five traits selected simultaneously, male flowering (MFL), female flowering (FFL), plant height (PHT), ear height (EHT), and 100-kernel weight (HKF) for five selection cycles for simulated data using phenotypic, genotypic, and molecular score variance–covariance matrices
