Thirty tomato genotypes were assessed for their genetic divergence using cluster analysis for 15 characters at the Central Research Farm, Gayeshpur, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, India during 2012–2013. Based on the determination of divergence for the characters genotypes were grouped into 9 clusters. The genotypes belonging to cluster VII had high performance for equatorial diameter, fruit weight, lycopene, TSS, β-carotene, ascorbic acid, total yield plant−1. The genotypes from the cluster VI, VII and VIII could be selected for hybridization programme to produce highly heterotic genotypes as these were found to be most divergent with a number of desirable traits such as fruit number/plant, ascorbic acid, β-carotene content and plant height.
