Forty tomato genotypes were evaluated in randomized block design with three replications at College of Agriculture, Vellayani, Kerala during October 2013 to April 2014. A wide range of variation was observed among the characters studied which have a great interest for polyhouse tomato breeding. Genetic divergence analysis was carried out using Mahalanobis D2 statistics and the 40 tomato genotypes were grouped into eight clusters. Cluster I was the largest cluster with twenty four genotypes followed by cluster II with ten genotypes and all other clusters were solitary. The highest intracluster distance was noticed in cluster II followed by cluster I. The highest intercluster distance was observed between clusters VII and VIII, followed by clusters IV and VIII. Lycopene content and truss per plant had maximum contribution towards total divergence followed by fruit length, fruit weight and yield per plant.
