Boxplots summarizing the range in genotype means and environment means across Australian rainfed (‘A_Rf’) and irrigated (‘A_Ir’), Managed rainfed (‘M_Rf’) and irrigated (‘M_Ir’), and Mexican rainfed-drought (‘Mx_Rf’) and irrigated (‘Mx_Ir’) environments for growth and yield-based characteristics measured on near-isogenic wheat pairs varying for the presence and absence of awns, and representing three to four genetically-contrasting wheat backgrounds. Harvest index and maturity biomass were not measured in Mexico. LSD is the least significant difference for testing among genotype×environment means at P=0.05.
