Abstract

Genetic divergence analysis using Mahalonabis D2statistic was carried out in twenty two tomato determinate genotypes. These genotypes were grouped into six clusters based on sixteen important fruit characteristics. The cluster-I was the largest containing seven genotypes followed by cluster-III with six genotypes. The diversity among the cultivars was measured by inter-cluster distance. The higher order of divergence was recorded between cluster II and V which was adequate for improvement of tomato by hybridization and selection. The genotypes included from the diverse cluster can be used as promising parents for hybridization, programme to obtain high heterotic response and thus better segregants in tomato for industrial purpose.
