Abstract: Rice is one among the foremost suitable crop for saline soils although it's usually considered moderately sensitive to salinity. The phenotypic response of twenty rice genotypes with salt stress at EC=12 dsm-1 was assessed under hydroponic condition at seedling stage. The rice genotypes FL-478, IR68144-2B-2-2-3-1-120, IR-68144-2B-2-2-3-1-127 were found tolerant, while IR-91167-99-1-1- 1-3, NUD-3, NUD-2, CSR-13, IR-92953-49-1-3 and NDRK-2008 showed moderately tolerant to salinity and genotypes NDR-359, MTU-1010, TARAMON, SAMBHA MANSURI, SWARNA IR-28 and AYYAR showed vulnerable to salinity. Tolerant varieties are suggested to use as donor parents for salinity tolerance in back cross breeding and for allele mining for salinity tolerance gene/QTLs.
