The present aims to judge the corporal support of eight edible grain genotypes fortitude to salt stress at shrub stage under hydroponic method. Salinity is a important abiotic determinant that influences edible grain education in the planet along the marshy extents. The seasoning touched regions in India is supposed expected about 8 to 10 heap hectares that causes significant decline in edible grain progress and yield. In order to boost the edible grain cultivars for seasoning resistance, pick of the suitable genotypes is made necessary. The Hydroponics experiment was attended at Glass apartment, Department of crop study of animal, 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 tree limits were shortened under salty environments, Na+ ion Concentration and Na+/ k+ percentage was taller in salty treatments distinguished to control. However, K+ ion assimilation depreciated accompanying growing salinity level. Electrolyte outflow and osmotic potential had growing style 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 rather open-minded; ADT 37 was acted as exposed and IR 64 was performed as very exposed. Salt inferred osmotic stress leads to physical dryness, causes many disorders and harms in plant. Ion build-up further causes change in osmotic potential of plant; for fear that such osmotic shortcoming and confine the effort of sodium and chloride ions into plants. To establish genotypes that are easygoing to seasoning stress all along the small tree stage and to increase rice development and yield so that meet internal necessities, this somewhat research should.
