Tomato (Solanum lycopersicum) is one of the most important vegetable crops belongs to the family Solanaceae and acts as a model system for genetic and genomic studies. It is highly monomorphic at molecular level due to intensive selection during domestication. However, introgressions from wild species for potential traits led to increased diversity in the present day cultivars.  Eventually, it resulted in difficulty in identifying potential breeding material for crop improvement. In the present study, molecular genetic diversity analysis of 29 inbred lines and 3 natural mutant lines, with respect to fruit ripening, was carried out using 245 microsatellite markers derived from sol genomics network database. A UPGMA based genetic tree was constructed using 68 polymoprhic loci, which differentiated the genotypes into two main branches.  PCA also supported the UPGMA based genetic diversity analysis with minor exceptions.
