The traits were male flowering (MFL), female flowering (FFL), plant height (PHT), ear height (EHT), and 100-kernel weight (HKF) for one and two selection cycles for simulated data using phenotypic, genotypic, and molecular score variance–covariance matrices. The signs and economic weights of the selection indexes for each trait are shown in parentheses.
