Abstract:
A set of forty five groundnut genotypes were assessed the genetic diversity during kharif season of 2019 using Mahalanobis D² statistics. Among the characters studies, the biological yield per plant (g) contributed highest percentage towards the total genetic divergence. The groundnut genotypes were grouped into 8 clusters. Among these 8 clusters, cluster I had maximum number of genotypes 17 followed by cluster II with 11 genotypes, cluster III with 9 genotypes, cluster IV with 3 genotype, cluster VI with 2 genotypes and the remaining clusters (V, VII, VIII) were solitary cluster consisting of only one genotype. Cluster II had the maximum intra cluster distance followed by cluster IV. The maximum inter-cluster distance was found between cluster I and VI followed by cluster II and VI. Cluster VI (RG 584, RG 604) showed the highest cluster mean for kernel yield per plant (g), pods per plant, dry pod weight per plant (g), biological yield per plant (g) and harvest index (%). Hybridization between genotypes of cluster I and VI followed by cluster II and VI could yield better segregants.
