Abstract: Thirty six genotypes were tested in a randomized block design with 3 replications. The characters under study were days to flowering, plant height, productive tillers per plant, duration of reproductive phase, days to maturity, spike length, number of spikelets per spike, number of grains per spike, biological yield, harvest index, test weight and grain yield per plant. The computed D2 and D values varied from 337.95 (18.38) to 5084.74 (71.31) which showed considerable genetic divergence among the different genotypes. The 36 genotypes were grouped into 5 clusters. The intra-cluster distance ranged from 18.38 to 71.31. The maximum inter-cluster distance was between cluster III and V. It suggested the hybridization possibilities between the genotypes included in these clusters by virtue of their being of wide genetic diversity.
