Abstract: The present study was carried out during Rabi seasons of 2016-17 and 2017-18 at Main Experiment Station of Department of Vegetable Science, Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) India. The experimental materials of the study comprised of 54 treatments of tomato [40 F1’s and 14 parental lines (10 lines viz., NDT-1, NDT-2, NDT-3, NDT-4, NDT-5, NDT-6, NDT-7, NDT-8, Azad T-6, Arka Saurabh and 4 testers viz., Pusa Ruby, Punjab Chhuhara, Arka Vikash and Arka Meghali]. The 14 parents were involved in a crossing programme to develop a line × tester set (10 lines + 4 testers + 40 F1’s). The experimental materials (40 F1’s and 14 parental lines) were evaluated in Randomized Complete Block Design (RBD) with three replication having each experimental unit with spacing of 60cm × 50cm with plot size of 1.2m ×3.0m.The observations were recorded on eighteen characters, viz., days to 50 % flowering, days to first fruit set, days to first fruit harvest, plant height (cm), number of primary branches per plant, number of fruits per cluster, number of fruits per plant, fruit weight per plant (kg), average fruit weight (g), fruit length (cm), fruit girth (cm), number of locules per fruit, pericarp thickness (mm), total soluble solids (TSS), ascorbic acid (mg/100g fresh fruit) total fruit yield per plant (kg). Fifty four genotypes were grouped into 8 different non over lapping clusters. Maximum intra-cluster distance was found for cluster-VII in first year, cluster-V in second year and pooled followed by cluster-IV in both the years and pooled. The highest inter-cluster distance was observed between cluster-III and cluster-VI in first year and pooled, cluster-IV and cluster-VII in second year followed by cluster-VI and cluster-VII in both years and pooled. Maximum contribution in genetic divergence showed by plant height and minimum contribution showed by days to first fruit set and days to first fruit harvest.Thus, there exists ample variation for improvement after selection in the available germplasm of tomato.
