Physiological characterization of mutant (MM11) under reproductive stage drought stress (RDS) conditions. MM11 plants (M7 Generation) showed better yield and physiological growth performance under stress conditions in comparison with MTU1010. A Phenotypic differences in MTU1010 and MM11 plants under well-watered (WW) and moisture stress at reproductive stage and in mature panicles. B Quantitative differences in yield (PH, plant height; CH, culm height; NT, number of tillers; PL, panicle length; NSP, number of spikelet/panicle; NFG, number of filled grain/plant; TGW, thousand grain weight; GYP, grain yield/plant); photosynthesis (Pn, photosynthesis rate; Ci, intercellular CO2 level; gs, stomatal conductance; SLA, specific leaf area; RWC, relative water content; WUEi, intrinsic water use efficiency; iWUE Instantaneous water use efficiency) and anti-oxidant (MDA, malondialdehyde; Proline; GPX, guaiacol-peroxidase; CAT, catalase attributes during MM11 and MTU1010 growth under RDS. *indicates significant variation in drought when compared to well-watered (WW) values. Data represented in the figure are means of six to twelve biological replicates. Vertical bars indicate the standard error. The complete statistical data is provided in Supplementary Table S1C. *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001
