Changes in the Osmolyte accumulation in different genotypes of wheat under normal (26 ± 2°C) and terminal HS (36 ± 2°C) conditions in (A) Leaves, (B) Stem, and (C) Spikes. Thermotolerant—HD2967, HD2285, Thermosusceptible—HD2932, WR544; Leaf, stem and spike collected during grain-filling stage were used for the proline estimation by the method of Bates et al. Different letters above each bar indicate a significant difference (p < 0.05) between treatments (one-way ANOVA); Vertical bars indicate s.e (n = 3).
