Abstract
Salt stress poses a significant threat to crop growth, productivity, and quality, particularly affecting mungbean due to its glycophytic nature. This study aimed to identify salt-tolerant mungbean genotypes by exploring their physio-biochemical responses to salinity. Nineteen genotypes were tested under control and 80 mM NaCl conditions to assess the impact on seed germination and early growth. Subsequently, eight genotypes with differential salt tolerance ability were further studied for their physio-biochemical traits. Salinity reduced seed germination, seedling length, and weight, except for IIPM 20-2. Tolerant genotypes showed less decline in amylase activity, water uptake, reserve mobilization, and photosynthetic pigments, while exhibiting increased phenol content, guaiacol peroxidase, superoxide dismutase and catalase activity and less cell membrane damage. Salt-tolerant genotypes such as Samrat, IIPM 20-2, ML 750-1, and MH 1772 are recommended for cultivation in salt-affected regions to enhance mungbean production.
