This study was conducted for characterization of 22 tomato varieties based on total soluble seed storage protein using electrophoresis on sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) .Sex varieties show distinctive fingerprint (Sanam, Helam, Oula, Kenanh, Shady lady, Carioca) and low polymorphism (46%) was observed. The overall analysis of the results reveal high level of homogeneity was detected. Reduction in the genetic diversity among modern tomato cultivars may be attributed to the recent trend towards breeding for similar plant and fruit characteristics.
