Genetic diversity for seed yield in a large collection of clusterbean (Cyamopsis tetragonoloba (L) Tauh.)

Two hundred thirty.one Yermplasm-tines of clusterbean (Cyamopsis tetragonoloba) were evaluated alone with three checks for seed yield and its components in augmented design. Pods per plant exhibited highest variability and contribution to divergence. This trait was also significantly and positively correlated with seed yield which indicates its importance as selection criteria. Following non-hierarchical Euclidean analysis, all the 234 genotypes were grouped into 12 clusters with variable number of genotypes. The highest genetic divergence was observed between cluster V and IX, whereas cluster III and VIII were, closest one. On the basis of genetic divergence and mean performance eight diverse and superior genotypes, being exceptionally good for one or more traits and reasonable for others in comparison to checks, were selected:Old these genotypes may be useful in multiple crossing or diallel selective mating system to recover transgressive segregants.
