Accumulation of salt in the soil has deleterious effects and leads to a reduction in crop production, including rice. Use of salt tolerant variety considered the most economical and most effective way of increasing crop production on saline soils. Therefore, development of salt tolerant varieties considered as one of the strategies to increase rice production in saline prone coastal areas. Seed experiment was laid out to standardize the level of salinity which affects the growth attribute of rice plant with initial pH 6.8 and ECe (Electrical Conductivity of the extract of a saturated soil paste) is 1.39 dSm-1 Salt tolerance in Ten rice genotypes were studied under salinized (EC=8.5 dSm-1) soil conditions after 90 days of transplanting. The aim of the present investigation is to provide information on the effect of salinity on chlorophyll concentration and yield and yield components of rice genotypes to elucidate the effect of salinity on these factors. The outcome showed that the yield per plant (which ranged from 26.955 to 50.59 %), number of primary braches per panicle, chlorophyll concentrations (which ranged from 4.165616 to 27.86813), and number of productive tillers, panicle length, and fertility percentage and of all the genotypes were affected by salinity. However the results also showed that, genotypes Pokkali Nonabokra CSR 30 & CSR 13 showed better salinity tolerance than others.
