The present aims to judge the corporal base of eight edible grain genotypes fortitude to salt stress at large plant enclosed in bark and shedding leaves stage under hydroponic structure. Salinity is a important abiotic determinant that influences edible grain help in the experience along the marshy extents. The seasoning troubled extents in India is supposed expected about 8 to 10 heap hectares that causes significant decline in edible grain development and yield. In order to increase the edible grain cultivars for seasoning fortitude, choice of the suitable genotypes is made necessary. The Hydroponics experiment was administered at Glass family, Department of crop plant structure, Tamil Nadu land academy, Coimbatore. Study was attended to screen eight edible grain genotypes (CO 51, ADT 53, ADT 37, IR 64, CO 43, ASD 16, Pokkali; TRY 3) for salinity fortitude at early seedling stage. Results from this study emanated that that organism belonging to the vegetable kingdom limits were weakened under salty environments, Na+ ion Concentration and Na+/ k+ percentage was greater in salty treatments distinguished to control. However, K+ ion assimilation dropped accompanying growing salinity level. Electrolyte discharge and osmotic potential had growing current accompanying increasing salinity. The edible grain genotypes Pokkali, TRY 3, CO 43 were acted as easygoing; CO 51, ADT 53, ASD 16 were acted as a little easygoing; ADT 37 was acted as exposed and IR 64 was performed as very exposed. Salt inferred osmotic stress leads to physiologic dryness, causes many disorders and harms in plant. Ion aggregation likewise causes change in osmotic potential of plant; for fear that such osmotic inequality and confine the entrance of sodium and chloride ions into plants. To conceive genotypes that are open-minded to seasoning stress all along the tree stage and to increase rice progress and yield so that meet social necessities, this somewhat research should.
