Abstract

Genetic divergence analysis was carried out in 30 tomato genotypes using Mahalonabis D2 statistics. These genotypes were grouped into five clusters based on nineteen characters. Maximum divergence was recorded between clusters III and IV followed by cluster IV and V. Genotype MT-4 (Oval big) of cluster III was found to be best for yield and related traits, like number of primary branches, fruit length, diameter, weight and yield per plant. Similarly, BT-10 of cluster IV was suitable for quality traits, like TSS, ascorbic acid, juice, β-carotene and lycopene content. Genotypes of cluster III and IV can be used for the development of hybrid/varieties having higher yield and quality.
