A field experiment was conducted at Annamalai University experimental farm during Navarai 2000 to screening of rice accessions for yield attributes contributing to salinity tolerance and nutrient uptake. The rice accession of the high yielding and tolerant group recorded a higher value for the yield characters viz. number of productive tillers hill", number of filled grains panicle', straw yield and harvest index. Among the rice accessions of high yielding and tolerant group rice accession no. 12 (IR 60494- 2B-18-3-2-3) recorded the highest value for yield characters with higher value of N, P and K uptake and lower value of Ca, Mg and Na uptake. This rice accession no.12 was not affected by salinity due to salinity tolerance.
