Abstract
Comparative phenotyping assessment of four oilseed cultivars, two soybean (RAWAL and AJMERI) and sunflower (SF0054 and SF0024) in a water deficit environment, was studied. Phenotyping was performed using stress-induced physiological traits. Results depict that drought stress decreased the stomatal conductance, relative water content (RWC), and photosystem II quantum efficiencies of considered plants. Among the tested cultivars, SF0054 (sunflower) and AJMERI (soybean) have higher RWC, stomatal conductance, performance index (PIABS), the quantum yield of PSII (Fv-Fm ratio), and photochemical quenching (qP) comparing SF0024 and RAWAL under drought stress environment. Furthermore, SF0054 and AJMERI exhibited greater antioxidant enzyme activities and lesser H2O2 production under a drought stress environment. Therefore, these two cultivars could be used in crop improvement via plant breeding and genomics
