Diversity analysis was carried out with respect to nine morphological traits of sixteen tomato genotypes along with one check during rabi season of 2008. For diversity analysis at DNA level, five forward and reverse sequence related amplified polymorphism (SRAP) primers were used. The 18 combinations of SRAP primers produced 177 amplified products among which 106 were polymorphic (59.92% polymorphism). Comparison of UPGMA dendrograms of morphological and SRAP markers indicated non-significant correlation r = 0.019 (P = 0.56). Among all tomato genotypes, SRAP similarities ranged from 72 to 98%, indicating them as important sources of genetic diversity which can be exploited in breeding programme.
