The present investigation was carried out on F2 population developed from saline sensitive, Basmati rice (PS5) and saline tolerant, non-Basmati rice (CSR10) varieties. A set of F2 progenies were evaluated at reproductive stage under saline stress (EC~12 dS m-1) as well as non-stress (EC~1.0 dS m-1) environments during 2013. The aim of this study was to unveil the performance of identical F2 progenies under non stress and saline stress (reproductive stage) and to find out the suitable stress indices. There was a mean reduction of 89% in grain yield due to high saline stress (EC~12 dS m-1) in F2 population. High heritability (86%) coupled with high genetic advance (68.52%) and low heritability (30%) with moderate genetic advance (25.73%) was observed for grain yield in non-saline and saline environment, respectively. Under control, the significant correlation was noticed between grain yield and biomass (r=0.64), followed by grain yield and plant height (r=0.36). There was a low correlation (r= 0.28) between other agronomic traits and grain yield under saline stress. Correlation coefficient and biplot analysis of stress indices indicated that GMP, STI and MP were the best suitable indices among all evaluated indices. A severe reduction of grain yield and other traits at reproductive stage was observed in saline stress over non stress that is due to high toxic effect of salt. The high magnitude and degree of variability in F2 population could be utilized in varietal development. Tolerant lines of F2 population namely, CS10P5- 163, CS10P5-130, CS10P5-157, CS10P5-18, CS10P5-139, CS10P5-40, CS10P5-21, CS10P5-13, CS10P5-210 and CS10P5-85 were identified based upon their performance under both environments. Indices (GMP, STI, and MP) may be used for assessment and selection salt tolerant progenies. This population may be further used in QTL mapping and in genomic studies at reproductive stage saline tolerance in Basmati back ground. Keywords: F2 population, Reproductive stage, Rice, Salinity, Stress indices Introduction Around 90 per cent of rice is grown and consumed in Asia and is one of the most important and popular cereal crops. About 7 per cent (830 million ha) of the total global land is salt affected and this is one of the most important abiotic factors limiting growth and productivity of rice worldwide. The world cereal production is 2479 million tones with rice production of 675 million tonnes accounting for about 27 per cent of total food grain production in world (FAO, 2013). Although salinity affects all stages of growth and development of rice, but early seedling stage and reproductive stage are highly sensitive. Salinity stress significantly, reduces tiller number, spikelet number, spikelet fertility, panicle length and primary branches.
