WW well-watered, WD water deficit, G genotype, T water treatment, MS main stems, TS tillers, GY grain yield, GN grain number, IGW individual grain number. In pots, GY and GN are expressed per plant, while 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)
