In the present study, 22 tomato (Solanum lycopersicum L.) genotypes were evaluated to study the extent of genetic diversity through 20 quantitative traits. The genotypes were categorized into 5 distinct clusters using D2 statistics. Cluster I had the maximum number of genotypes (8), followed by clusters IV and V (4 genotypes each) and clusters II and III (3 genotypes each). Highest intra cluster was recorded in cluster III, while the inter cluster distance was maximum between cluster V and cluster IV (53,348.13) indicating the presence of wide range of variability among genotypes of the cluster. Fruit yield per plant contributed the maximum (64.50 %) to the genetic diversity, followed by fruit volume, number of fruits per plant, average fruit weight, number of locules per fruit, fruit diameter and fruit length. The cluster III recorded highest mean for the characters like fruit length (4.28 cm), fruit diameter (5.12 cm), fruit volume (115.58 cc), average fruit weight (114.20 g), pericarp thickness (6.70 mm) and fruit yield per plant (1.64 kg).
