In this study, the genetic diversity of 20 tomato genotypes was assessed under protected cultivation, focusing on 22 different characteristics. Through the application of D2 statistics, the genotypes were classified into seven distinct clusters. Cluster II consisted of the highest number of genotypes (six), followed by cluster III (four), cluster IV (three), cluster V (three), cluster I (two), cluster VI (one), and cluster VII (one). Cluster II exhibited the greatest intra-cluster distance, indicating a higher level of variation within the genotypes of this cluster. The inter-cluster distance between cluster I and cluster VI were the most significant. Among the clusters, cluster VI demonstrated the highest average values for several characteristics including fruit yield (1172.8 g), total number of fruits per plant (74.1), number of fruits per plant (5.2), number of clusters per plant (16.1), TSS (7.8 0Brix), plant height (181.3 cm), and primary branches (3.5).
