The output of stepwise selection, forward selection, and backward selection methods

Method	Most efficient subset	R2	RMSE	MAE
Stepwise Selection	PP, FPH, DPM	0.810	0.288	0.224
Forward Selection	PP, PH, DPM	0.816	0.281	0.219
Backward Selection	PP, FPH, DPM	0.808	0.291	0.227

PP: pods per plant, FPH first pod height from the ground, DPM days to physiological maturity, PH plant height, R² determination coefficient, RMSE root mean square error, MAE mean absolute error
