We compared the enzymatic antioxidative defence mechanisms of some regional soybean genotypes cultivated mainly in the regions of Maharashtra and Chhattisgarh. The variability in the activities of antioxidant enzymes superoxide dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT), and peroxidase (POD) and their changes under drought stress were investigated. The higher activity levels of antioxidant enzymes may contribute to better stress tolerance by increasing protection capacity against oxidative damage. Genotype NRC 37 and KDS 344 possessed higher SOD and APX activity which catalyzes superoxide free radical dismutation into H2O2 and O2 and defense against free radicals of oxygen under water stress. The maximum increase in peroxidase and catalase activity was recorded in leaves of NRC 37 and JS 335 help in biosynthesis of lignin which has a role in the defense against water stress by consuming H2O2. The antioxidant enzyme activities are used as indications of water stress in soybean plants and screening of drought resistant genotype.
