Genetic diversity studies in tomato (Solanum lycopersicon L.)

Fifty three genotypes of tomato were assessed for their genetic divergence using Mahalanobis D2 statistics. Based on D2 values of 24 traits genotypes were grouped into eight clusters. Maximum genotypes were grouped in cluster III (11) followed by cluster VI (10) the remaining 32 genotypes were distributed in six clusters, 9 in cluster V, 7 in cluster II, 6 in cluster IV, 4 in cluster I, 3 in cluster VI and 3 in cluster VIII. The mean intra and inter cluster distance (D) revealed that cluster VI highest intra cluster distance (50.975), While the inter cluster distance was maximum between cluster III and cluster VII (106.999) followed by cluster III and cluster VI (80.266). The characters like tritratable acidity, fruit pericarp thickness, pH contributed maximum to genetic divergence. | Genetic diversity studies in tomato (Solanum lycopersicon L.)
