Abstract:

Thirty five mungbean genotypes were evaluated to select superior parents with genetic diversity based on yield and physiological traits in order to develop high yielding varieties in mungbean. The results of multivariate analysis (D2) indicated the presence of considerable genetic divergence among these genotypes. The genotypes were grouped into seven clusters. Out of seven clusters, cluster I contained maximum number of thirteen genotypes, followed by cluster II with ten genotypes and cluster IV with seven genotypes. The maximum intra-cluster distance was recorded by cluster IV (34.70), while the minimum distance was noted in the clusters V, VI and VII (0.00) as they included single genotype each. The maximum inter-cluster D2 value was observed between cluster III and IV (153.62) followed by II and IV (145.11) and cluster IV and VII (110.29). While, the minimum D2 value was found between cluster V and VI (19.06). Based on genetic diversity studies hybridization programme might be initiated between GVIT-203 X WGG-42 (cluster III and IV) and KM-122 X EC-396117 (cluster II and IV) in order to get transgressive segregants, since these genotypes showed maximum diversity. The characters viz., leaf area duration, chlorophyll content, seed yield per plant, 100 seed weight and net assimilation rate had maximum contribution to the total genetic divergence.
