Abstract: The aim of this study was to evaluate the progress of five soybean varieties in relation to resistance to water unavailability. The cultivars BRS 1010IPRO, 80182RSF IPRO, M 6410 IPRO, NS 7676 and TMG 2370 IPRO were evaluated. Water scarcity occurs when water availability reaches very low levels, impairing the absorption that is essential for the progress of plant development, with effects such as leaf wilting and low efficiency. The study was carried out under monitored conditions, with irrigation stopped after phenological stage V-1. Physiological parameters were analyzed: relative leaf water content (RWC), aerial part dry mass (ASM), plant height (PH) and chlorophyll index (CI). The results indicated that the BRS 1010IPRO and 80182RSF IPRO cultivars showed greater tolerance, maintaining better physiological indices. It is concluded that these cultivars are suitable for cultivation in regions characterized by low rainfall.
