The present investigation consists of 35 rice genotypes including one check, which were obtained from Department of Genetics and Plant Breeding, SHUATS, Allahabad. The experiment was conducted during Kharif2017in RBD with three replications. The data were recorded for 13 quantitative characters to study Correlation and Path analysis. Analysis of variance revealed that there is considerable variability among the genotypes. Genotypes were found best on the basis of grain yield per hill, OM-6070 followed by CT-18148-6-9-5-1-2MMP and NDR-1045 (2% EMS). Correlation coefficient analysis revealed that days to 50% flowering, plant height, tillers per hill, panicles per plant, flag leaf width, flag leaf length, spikelet’s per panicle, days to maturity, biological yield and harvest index, test weight showed positive significant correlation with grain yield at both genotypic and phenotypic level. Path analysis indicated that panicle length, flag leaf width, spikelet’s per panicle, days to maturity, biological yield and harvest index, test weight had high positive direct effect on grain yield per hill at both genotypic and phenotypic level. Thus, these traits are identified as the efficient and potential for indirect selection for the improvement of rice productivity in the present experimental materials.
