Abstract:
Genetic divergence study was conducted on 33 pumpkin genotypes for thirty-seven characters at College of Horticulture, venkataramannagudem during 2022–2023. These genotypes were grouped into six clusters irrespective of geographic divergence, indicating no parallelism between geographic and genetic diversity. Cluster-I was the largest comprising 20 genotypes, followed by Cluster-II with 7 genotypes, Cluster-III with 3 genotypes. Clusters-IV, V and VI comprised one genotype each. As regards cluster means, Cluster-VI performed better in most of the biometric characters studied. Maximum inter-cluster distance was observed in Clusters-V and VI, followed by Clusters-IV and VI, and clusters-I and VI. Intra-cluster distance was highest in Cluster I.
