  Genetic divergence, correlation and path coefficient analysis among 19 genotypes of irrigated rice were studied for grain yield and yield contributing characters. The genotypes under study fell into five clusters. The inter cluster distances were higher than the intra cluster distances indicating wider genetic diversity among the genotypes of different clusters. The intra cluster distances were lower in all the cases reflecting homogeneity of the genotypes within each of the clusters. Regarding inter cluster distance, cluster II showed high genetic distance from all other four clusters. The genotypes from cluster II could be hybridized with the genotypes of any other clusters for producing transgressive segregants. Clustering pattern was not influenced by the geographic origin rather it was influenced by the pedigree of the breeding lines. Harvest index, panicle length and 1000 grain weight showed significant positive correlation with grain yield. Highest direct effect on grain yield was exhibited by spikelets/panicle followed by plant height, harvest index, 1000 grain weight and panicle length respectively. Grains/panicle, spikelets/panicle, flag leaf area, 1000 grain weight and plant height had highest contribution towards divergence respectively. Considering the relative contribution of different characters towards diversity and the effect of correlation and path coefficient all together; the characters like plant height, spiklets/panicle, grains/panicle, 1000 grain weight, flag leaf area and grain yield were found important. Genotypes having these characters of respective cluster would offer a good scope for the improvement of irrigated rice through rational selection.
