Genetic diversity evaluation among 16 Gloriosa accessions collected from different locations in Tamil Nadu was studied by using Inter-simple sequence repeat (ISSR) markers. Thirty six ISSR primers were used, among that 16 primers showed 83.56 per cent polymorphism and produced 213 amplicons. This indicates that there is a high level of variation at the genetic level among these accessions. The primer UBC-807 showed the highest PIC value (0.958), which represented the high efficiency of the individual primer. Gloriosa accessions GSU-6 and GSU-7 are highly similar with 68 per cent and GSU-7 and GSU-16 are distinctly similar with 39 per cent. Cluster analysis was done based on similarity coefficient value obtained from banding pattern of ISSR marker. The 16 Gloriosa accessions were grouped into two major clusters, of which one cluster contained all 15 accessions whereas as another cluster contained GSU-16 accession alone. This represents that the Gloriosa accession GSU-16 is genetically distinct from other accessions based on banding pattern.
