WW well-watered, WD water deficit, G genotype, T water treatment, GY grain yield, GN grain number, IGW individual grain number (mg), B above-ground biomass, HI harvest index. In pots, GY, GN, and B are expressed per plant, whereas in microplots, they are expressed per unit area (m²). Asterisks indicate significant differences (*p< 0.1; **p< 0.05; p< 0.001; ns, not significant). Means (n=3) sharing the same letters in columns do not differ (p< 0.1)
