Abstract:
D² values between the pairs of genotypes, 23 genotypes were grouped into thirteen clusters. Cluster IV and IX was largest having three genotypes followed by II, V, VII, X, XII and XIII which had two genotypes in each cluster. There were four solitary clusters I, III, VI, VIII with genotypesK-9533, UP 2594, Raj 1555, NW 1012, K 9465, respectively. The mean values of each of the nine characters for the thirteen clusters showed that cluster XIII, which was most diverse, had high seed yield and number of siliquae per plant. Cluster VIII also represented entries with high seed, number of siliquae per plant and number of seeds per siliqua. Cluster IX had genotypes with highest test weight. These clusters could be regarded as useful sources of genes for seed yield. Cluster XI with the minimum number of days to maturity can be considered as a good source for earliness. The results revealed that 1000-seed weight contributed maximum to genetic divergence (61.03%) followed by effective tillers per plant (12.04%), spike weight (10.74%), peduncle length (7.87%) and harvest index (2.40%), which exhibited greatest contribution to genetic divergence, can be the basis of the selection of genetically diverse parents for hybridization.
