The experiment was carried out to explore correlation and path coefficient analysis in 48 rice genotypes for nine characters viz., days to first flower, plant height, number of tillers per plant, number of panicles per plant, number of grains per panicle, panicle length, thousand grain weight, grain L/B ratio and grain yield per plant. The genotypic correlation coefficients showed higher magnitude than phenotypic correlation coefficients which indicated masking or modifying effect of environment. The genetic correlation revealed that grain yield per plant had strong negative and significant association with days to first flower at both genotypic and phenotypic levels. So it could be inferred that grain yield and days to first flower could be used as selection criteria for the improvement of grain yield per plant. Scrutiny in path analysis indicated that maximum direct effect on grain yield was exhibited by number of panicles per plant. Hence the trait should be taken in account of breeding programme to develop the maximum of threshold yield obtaining new rice varieties or hybrids.
