Eighty two extant cultivars of tomato (Solanum lycopesicum L.) were evaluated in field and glasshouse condition for analyzing the multivariate analysis of twenty diverse physio-morpho-metric traits including tomato leaf curl virus (ToLCV) and early blight (EB) disease. Three genotypes Punjab Varkha Bahar-1, Punjab Varkha Bahar-2 and Swarna Naveen showed moderate resistant reaction for ToLCV and Kashi Sharad was highly resistant for EB disease. Whereas, highest value of GCV, PCV and GA% were found for fruit thickness of pericarp but highest heritability and genetic advancement was recorded for the average weight which indicated additive gene action. Most of morphological characters showed maximum value in PCA II group but highest total variance percent (61.03%) accounted in PCA I and lowest (4.71%) in PCA IV group. There were fourteen clusters distinguished in the cluster analysis. In Mahalanobis D2 distance analysis, maximum genotypes grouped in cluster ‘1’ and ‘3’, whereas, remaining clusters had single diverse genotype. However, the inter cluster distance was found maximum to the tune of 52.95 between cluster ‘13’ and ‘11’ and minimum (7.11) between cluster ‘4’ and ‘6’. The findings indicated that breeding between the genotypes from clusters ‘11’, ‘13’ and ‘4’ can be utilized for getting superior recombinants.
