Table 3 Prediction ability of the HEL dataset for single trait multi-environment trial (STMET) analysis for five models: EAD (M1); EAD + GE (M2); EADW (M3); EADW + GE (M4) and EADW + GW (M5), for both cross-validations CV1 and CV2. PAs were calculated by 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
