This investigation was carried out to explore genotype specific fingerprinting of 32 N. sativa L. genotypes based on randomly amplified polymorphic DNA markers. From 58 random primers used, 15 primers generated 249 reproducible and scorable amplification products across all the genotypes, out of which 164 (66%) fragments were polymorphic revealing a high level of polymorphism among these genotypes. The proportion of common bands was low (34%). The size of the amplification products on agarose gels ranged between and kb. In 13 genotypes, 27 bands of different masses (kilobases) were recorded and were considered specific to those genotypes. These specific/amplified PCR products can be used as molecular markers for identification of germplasm and resource protection of Nigella sativa L. genotypes. Specific bands were observed for individual primers that could resolve genetic diversity among several genotypes (PK-020545, PK-020567,
