Rice is known as major staple food crop in India by providing food to more than 70 per cent population. An experiment was carried out in Augmented Design for evaluation of eighty eight (88) diverse rice genotypes including three checks (NarendraUsarDhan 3, Jaya and CSR-36) under timely sown and irrigated conditions in sodic soil. The observation on eleven (11) characters was utilized for estimation of mean, range, least significant differences, correlations and path-coefficient. The genotype, NDRK 5018, followed by NDRK 50023, NDRK 5082, NDR 507, NDRK 5070, CSR 13 and NDRK 5029 produce highest grain yield per plant. High mean performance for several other characters was also found in the above mentioned genotypes and can be useful as parental materials in future breeding programme in sodic soil. Character association studies divulged that grain yield per plant (GYPP) showed high positive association with biological yield per plant (BYPP), spikelets per panicle (SPP), panicle bearing tillers per plant (TPP), flag leaf area (FLA) and harvest index (HI). Path analysis revealed that biological yield per plant (BYPP) and harvest index (HI) are the major direct contributors towards expression of grain yield per plant (GYPP) whereas biological yield per plant (BYPP) came out as the most important indirect yield component. Hence, these characters need to emphasize as a selection criteria for rice improvement under sodic soil condition.
