The present investigation consists of thirty rice genotypes and the experiment was conducted during <em>Kharif</em>-2016 in laboratory condition in the department of PMB & GE. Salinity screening for thirty rice genotypes was performed at the seedling stages in the hydroponic system. Phenotyping of the germplasm was done at EC 6dS/m at seedling stage. Based on modified standard evaluation score for visual salt injury at seedling stage, three (IR-68144-2B-2-2-3-166, IR-68144-2B-2-2-3-1-120 and IR-68144-2B-2-2-3-1-127) genotypes were salt tolerant, ten (IR-91167-133-1-1-2-3, RP-4993-55-14-3-5-1, IR-91167-31-3-1-33, IR-92953-49-1-3, IR-84722-82-2-3-3-3, IR-91167-99-1-1-1-3, IR-91171-66-3-2-1-3, R-RHZ-14-7, IR-82475-110-2-2-1-2 and IR-92966-95-1-3) were moderately tolerant, nine(IR-64, IR-91175-27-1-3-1-3, RP-BIO-5478-185M, IR-92960-75-1-3, NUD-3, IR-91171-70-3-3, Ayaar, IR-91158-85-3-2-33 and IR-836 68-35-2-2-2) were susceptible and eight (NDR-359, MTU-1010, Taramon, IR-83294-66-2-2-3-2, R-RHZSM-4, R-RHZ-2, Sambha Mansuri and Swarna genotypes were highly susceptible. The indentified salt tolerant genotypes can be potential germplam sources for future breeding program.
