Over many years, tomato adapted to the geography of Turkey has shown a high biodiversity. In this research, with 76 local tomato genotypes collected from 52 different provience, 4 foreign and 8 wild species, total 88 tomato genotypes were used. Morphological variations among these materials were investigated. Some of the local genotypes were determined to be accessions increasing variations. A cluster diagram obtained from the morphological descriptors produced ten main sub-cluster groups of tomato accessions at a coefficient of 0.15. Accessions were put into cluster groups based on certain qualities unique. It was observed that 86 out of 88 tomato accessions under study were distinct accessions. G80 and G83 were recorded similar (94%) accessions in all accessions. Similarity coefficient values among the 88 accessions ranged from -0.11 to 0.94. Accessions with similar quantitative and qualitative morphological characters appeared well grouped in the same cluster. These accessions are considered as important genetic resources in tomato breeding studies. Keywords : Biodiversity, Local genotypes, Solanum lycopersicum, Morphological characterization, Clustering
