Studies on genetic diversity for yield, quality and yield attributing traits in cluster bean [Cyamopsis tetragonoloba (L.) Taub.] genotypes

Abstract

The study was carried out to assess the genetic divergence among 56 cluster bean genotypes using MahalanobisD2. Fifty-six genotypes were grouped into 8 clusters based on 11 characters. The intra-cluster distances wereseen to be lower than the inter-cluster distances. The maximum inter-cluster distance was noticed betweencluster VI and VII whereas, inter-cluster D2 value was least between cluster I and V. The maximum intra-clustedistance was observed in cluster IV. Clusters V, VII and VIII had only one genotype each and hence intra-clusterdistance was 0.00. The per cent contribution towards genetic diversity was maximum in 100 seed weight (52.08%followed by the protein content of pods (45.19%). On the basis of inter-cluster distances observed,the genotypeswith specific characters can be utilized for the hybridization programme.
