In this study 25 introgression lines developed by involving CSR-27 and MI-48 rice varieties were evaluated under normal
and salinity stress conditions. Observations were recorded for yield and yield contributing traits. The genotypic correlations
were generally similar in nature and higher in magnitude with the corresponding phenotypic correlation coefficients. Data in
salinity condition revealed that grain yield having positive and significant correlation with panicle bearing tillers per plant
and biological yield per plant while in normal condition with biological yield and harvest index. The path coefficient analysis
indicated that biological yield and harvest index had maximum positive direct effect on grain yield at phenotypic level under
salt condition. Biological yield, harvest index, plant height and spikelets per panicle have positive direct effect on grain yield
per plant under controlled condition.
