Tomato (Solanum lycopersicum L.) is one of the most important economically plants in the family Solanaceae. Information about genetic diversity of any crop is important for successful employment of breeding programme and is of great significance to attain sustainability in crop production. The objective of this study was to evaluate the genetic diversity of 24 genotypes of tomato collected from ICAR-IIVR, Varanasi, India, using 25 simple-sequence repeats (SSRs). A total of 64 alleles were detected at an average of 2.720 alleles per SSR locus. The average major allele frequency and polymorphic information content were 0.6622 and 0.3875, respectively. The UPGMA cluster analysis induced by SSRs data grouped 24 tomato genotypes into 3 main clusters. Cluster I and II comprised 15 and 8 genotypes respectively, and a single tomato genotype CO-3 was grouped in cluster III. As per our expectation genotypes from same genetic base showed similarity among each other. The information obtained from SSR markers may well assist tomato breeders in identifying a limited number of highly differentiated genotypes to be selected for further use in developing suitable variety/genotypes with good quality potential.
