FIGURE 3.

Scatter plot of the predicted and observed values of the regression coefficient of a linear regression (A) or of a quadratic regression (B,C) of GY on HD in scenario CVnewE. Observed α and β correspond to the estimates obtained from the linear (A) and quadratic (B,C) regressions of GY on HD in each environment. Predicted α and β correspond to the prediction of the α (A) or α and β (B,C) of the predicted environment (leave-one-environment-out scheme), using a multiple linear regression of the α (A) or α and β (B,C) estimated in the calibration environments on the environmental covariates. The black line corresponds to the line y = x.
