Present investigation was carried out to examine the association and path analysis for grain yield and its attributing traits in 25 rice genotypes. The result of character association revealed that number of productive tillers per plant (rp 0.881 & rp 0.993) exhibited highly significant and positive correlation with grain yield per plant followed by 1000-grains weight (rp 0.607 & rg 0.645), panicle length (rp 0.369 & rg 0.459), plant height (rp 0.284 & rg 0.409), days to maturity (rp 0.293 & rg 0.325) and days to 50 per cent flowering (rp 0.294 & rg 0.308) at phenotypic as well as genotypic level respectively proving that grain yield could be enhanced by selecting genotypes containing higher values for these attributes. The path analysis result showed that the maximum direct positive effect on the grain yield per plant was exerted by number of productive tillers per plant followed by 1000-grain weight, panicle length, plant height, days to maturity and days to 50 percent flowering. These characters also exhibited prominent role as indirect effects of most component traits on grain yield per plant hence these traits should be considered as an essential selection criteria toward optimizing crop yield.
