Drought alters rice morphophysiology and reduces grain yield. This study hypothesized that the combined analysis of morphophysiological and agronomic traits enables a systemic approach to responses to water deficit, allowing the selection of resistance markers to upland rice. The objectives were to evaluate the effects of water deficit applied at the reproductive stage in plant water status, leaf gas exchanges, leaf non-structural carbohydrate contents, and agronomic traits in upland rice genotypes; and to verify if the analyzed variables may be applied to group the genotypes according to their tolerance level. Water deficit was induced by irrigation suppression in eight genotypes at R2-R3. Physiological and biochemical traits were evaluated at the end of the water deficit period, thenceforth irrigation was restored until grain maturation for the analysis of the agronomic traits. Water deficit reduced: Ψw (63.64%, average); gs (28–90%); transpiration rate (40.63–65.45%); RWC from Serra Dourada to Esmeralda (43.36–61.48%); net CO2 assimilation from Serra Dourada to Primavera (70.04–99.91%); iWUE from Esmeralda to Primavera (83.98–99.85%); iCE in Esmeralda (99.92%); 100-grain weight in CIRAD and Soberana (13.65–20.63%); and grain yield from Primavera to IAC 164 (34.60–78.85%). Water deficit increased Ci from Cambará to Early mutant (79.64–215.23%), and did not affect the tiller number, shoot dry biomass, fructose, and sucrose contents. The alterations in the variables distinguished groups according to the water regime. RWC, Ψw, leaf gas exchanges, and iCE were valuable traits to distinguish the water regime treatments, but not to group the genotypes according to the drought tolerance level.
