Genetic Diversity in Tomato (Lycopersicon esculentum Mill.) Genotypes

Genetic divergence was evaluated in 13 tomato genotypes from Nagaland to determine their nature and extent. These genotypes were classified into five clusters based on their D² values, with no correlation found between genetic diversity and geographical distribution. Among the various traits examined, yield per hectare, fruit diameter, total soluble solids (TSS), and Vitamin C content significantly contributed to genetic diversity. Cluster III genotypes could be employed as diverse parents in hybridization programs, particularly in combination with cluster IV genotypes, to enhance variability in subsequent generations.
