The goal of this study was to identify tolerant and sensitive genotypes by screening 30 Ricebean accessions in recognised and standardised doses of 120 mM NaCl salt concentration for salinity tolerance during the early seedling stage. More salt inhibits growth, resulting in leaf damage, necrosis, and the eventual death of the crop. Salinity has harmed approximately 21.5 million hectares of cultivable land in Asia. Ricebean, a member of the Fabaceae family, is a fast-growing summer legume crop that produces high-quality green fodder rich in protein, calcium, phosphorus, tryptophan, and carbohydrates. To investigate the ability of Ricebean to survive imposed salinity, an experiment in Completely Randomized Block Design (CRBD) with three replications was set up in a growth room of the Department of Plant Breeding, Faculty of Agriculture, Mohanpur, Nadia, West Bengal, India. After standardising the methodology, data on several seedling growth parameters were collected for screening of accessible 30 Ricebean genotypes at a 120 mM NaCl salinity level, which was determined as the optimum salt concentration for screening Ricebean genotypes.
Six genotypes, KRB-77 (81.58 and 0.41), KRB-273 (79.97 and 0.44), KRB-81 (79.63 and 0.44), KRB-10 (79.17 and 0.60), KRB-95 (76.48 and 0.51), and KRB-271 (71.31 and 0.54), showed greater tolerance to the imposed salinity level, whereas genotypes KRB-44 (19.48 and 1.73), KRB-66
