The present investigation was carried out to determine genetic variability, correlation analysis and path coefficient analysis in 900 F3 segregating progenies of the cross (Sahbhagidhan and BPT-5204 Sub-1). The population was raised at Rice research farm of department of Genetics and Plant Breeding, BAU, Ranchi during kharif 2018. The population exhibited high GCV and PCV for the traits viz. seed yield per plant, number of panicles per plant number of spikelets per plant, number of grains per plant, number of spikelets per panicle and number of grains per panicle. High heritability coupled with high genetic advance was observed for traits viz. plant height, number of tillers per plant, number of spikelets per panicle and number of grains per panicle. Seed yield per plant was found positively and significantly correlated with number of tillers per plant, number of panicles per plant, number of spikelets per plant, number of grains per plant, number of spikelets per panicle, number of grains per panicle, fertility percent, grain width and panicle length. Path coefficient analysis revealed that direct effect of number of spikelets per plant and number of grains per plant were high as well as positive and the indirect effect of all characters via these were positive except number of the traits viz. tillers per plant and number of grains per panicle for which the indirect effects on yield were negative.
