Abstract: The present investigation was conducted with 50 genotypes including 4 checks viz. Swarna ©, NDR 8002 ©, Pooja, CG. Dhan 1919 during Kharif, 2023 in RBD with two replications. at Research cum Instructional Farm of S. G. College of Agriculture and Research Station Kumhrawand, Jagdalpur in Kharif 2023.High heritability was observed in flag leaf width, Moderate GCV and PCV values was observed for character like number of effective tillers per plant, Genetic advance as percent of mean was high for flag leaf width, association analysis revealed that grain yield showed high positive significant association with characters like biological yield, harvest index, test weight. showed positive significant association while, positive non significants corelation was recorded character like days to 50% flowering, number of effective tillers, panicle length, grain L/B ratio, kernel length, kernel L/B ratiodistributed the 50 genotypes into six clusters, of which cluster I was the largest with 15 genotypes. Cluster II had maximum intra-cluster values of 5.16 and the maximum inter-cluster distance was observed between the clusters III and V (40.51) followed by cluster IV and V (28.39) indicating the importance of the genotypes present in these clusters for exploiting heterosis for the desirable traits of these clusters.
