Abstract

The experiment was conducted in a randomized block design with 38 genotypes (including three checks) of tomato (Solanum
lycopersicum L.), in three replications for thirteen quantitative traits. The analysis of variance showed that mean squares due
to genotypes were significant for all the characters. Based on the Mahalanobis D2 statistics, 38 genotypes were grouped into 15
clusters. The maximum number of genotypes (9) were grouped into Cluster I. The highest inter-cluster distance was observed
between Cluster XI and Cluster VI, indicating that crossing genotypes from these two clusters is likely to produce highly heterotic
and diverse segregants. Highest per cent contribution towards clustering of genotypes were observed in total soluble solids, followed
by unmarketable fruit yield/plant, average fruit weight and equatorial diameter of fruits.
