Rice germplasm diversity is the mainstay for rice improvement programmes. High heritability accompanied with high genetic advance indicated the predominance of additive gene action for the traits number of tillers/plant, biological yield/plant, panicle weight/plant, number of spikelets/panicle, fertile spikelets/panicle, spikelet density, grain yield/plant, panicle index, harvest index, head rice recovery, amylose content. It indicates that the heritability is most likely due to additive gene effect and selection may be effective. The path coefficient analysis of different traits contributing towards grain yield revealed that stem length followed by panicle length, panicle index, fertile spikelets /panicle, panicle weight/plant, decorticated grain length, 1000-grain weight, milling percentage, number of panicle/plant and grain breadth had positive direct effect towards grain yield. Therefore, these characters may be given importance during hybridization programmes.
