Genotypic and phenotypic coefficients of variation were highest for 100-seed weight followed by seed yield per plant, number of pods per plant, number of secondary branches per plant and plant height. High heritability coupled with high genetic advance as percent of mean was observed for the 100-seed weight, number of seeds per plant, number of pods per plant, number of secondary branches per plant, plant height, seed yield per plant suggesting that the selection of these traits would be effective for the desired improvement. The cluster I was the largest cluster comprising of 21 genotypes, cluster VII was 6 genotypes, cluster II with 5 genotypes and cluster VI with 4 genotypes, cluster IV (2) genotypes. The cluster III, V, VIII, IX, X, XI was solitary since they had only one genotype. The highest cluster distance (D=28.40) was found between the clusters VII and XI, followed by the cluster VI and VII (26.63) and cluster IV and VII (24.01). This indicated that hybridization among the genotypes between these clusters would produce successful hybrids and desirable segregants in further generations. The D² statistics showed that there was adequate diversity among the genotypes. On the basis of D² values 44 genotypes studied were grouped into eleven clusters. On the basis of inter cluster distance and cluster means the genotypes viz., BG-4010, Phule Vikram, NDG 18-9, RVSSG-79, GNG-2462, RKG 19-1, BAUG-106 and BRC 9-14 were identified for their use in hybridization programme.
