The present experiment was conducted during spring-summer 2013 to study genetic variability, correlation, path coefficient analysis, and genetic diversity for quantitative and qualitative traits in tomato in vegetable research farm Hisar. Using Mahalanobis D2 statistics method, the 27 genotypes were grouped into nine clusters, indicating the presence of diversity for different traits. The cluster I had the highest number containing 16 genotypes followed by cluster III and VII containing three and two genotypes respectively. However, the cluster II, IV, V, VI, VIII and IX were solitary. The maximum intra-cluster distance was recorded within cluster III (10.88) and the maximum inter-cluster distance between cluster VI and VII (20.80), indicating the existence of wide genetic variability. Based on mean performances, the cluster VIII with single genotype ranked first and appeared to contain the potential genotype.The cluster VIII and II registered high plant height. The genotypes included in clusters V and VIII took less number of days to 50% flowering (29.67). The cluster III registered high fruit yield per plant (1004.60), average fruit weight (38.07), and ascorbic acid (28.7) can be utilised in breeding programme for enhancing their respective characters. The cluster IX had high number of fruits per plant (40.53). Based on cluster mean analysis these genotypes can be used in crop improvement programme in tomato for above-mentioned characters.

Abstract
The present experiment was conducted during spring-summer 2013 to study genetic variability, correlation, path coefficient analysis, and genetic diversity for quantitative and qualitative traits in tomato in vegetable research farm Hisar. Using Mahalanobis D2 statistics method, the 27 genotypes were grouped into nine clusters, indicating the presence of diversity for different traits. The cluster I had the highest number containing 16 genotypes followed by cluster III and VII containing three and two genotypes respectively. However, the cluster II, IV, V, VI, VIII and IX were solitary. The maximum intra-cluster distance was recorded within cluster III (10.88) and the maximum inter-cluster distance between cluster VI and VII (20.80), indicating the existence of wide genetic variability. Based on mean performances, the cluster VIII with single genotype ranked first and appeared to contain the potential genotype.The cluster VIII and II registered high plant height. The genotypes included in clusters V and VIII took less number of days to 50% flowering (29.67). The cluster III registered high fruit yield per plant (1004.60), average fruit weight (38.07), and ascorbic acid (28.7) can be utilised in breeding programme for enhancing their respective characters. The cluster IX had high number of fruits per plant (40.53). Based on cluster mean analysis these genotypes can be used in crop improvement programme in tomato for above-mentioned characters.
