Table 4 Prediction ability of the HEL dataset for multi-trait multi-environment trial (MTMET) analysis for the five models under study: EAD (M1); EAD + GE (M2); EADW (M3); EADW + GE (M4) and EADW + GW (M5), for both cross-validation schemes CV1 and CV2. PAs were calculated per environment for grain yield (GY), ear height (EH), and plant height (PH). μ is the average PA across environments and % is the difference between that PA and the highest PA. Standard deviation appears before the “±” sign
