dc.descriptionDeveloping and selecting genotypes that are responsive or tolerant to variations in water availability is essential for sugarcane production. The aim of this study was to evaluate the performance of 32 sugarcane genotypes under different water conditions. The responses of physiological variables as a function of different irrigation levels were evaluated. The experiment used a Randomized Complete Block Design (RCBD) in a split-plot arrangement. Four irrigation levels (20 %, 40 %, 60 %, and 100% of crop evapotranspiration) were allocated to main plots, and the subplots were represented by 32 genotypes belonging to different genera and species. The evaluated physiological variables of the plants were photosynthesis rate (A), stomatal conductance (gs), quantum yield of CO2 assimilation (PhiCO2), and transpiration rate (E). Leaf vapor pressure deficit (VpdL) was estimated based on leaf temperature. The results revealed that genotypes 10, 26, and 29 consistently maintained high physiological performance across all irrigation levels, whereas genotype 7 showed notable resilience under water deficit. These genotypes are identified as promising candidates for cultivation under water-limited conditions and may support the selection of efficient, drought-tolerant material for semi-arid regions.
