Abstract Chilli belongs to genus Capsicum which possesses enormous wealth of genetic diversity. The amount of genetic diversity determines the level of crop improvement programme and this indicated the genus Capsicum has an unusual amount of diversity. In the present study; genotypes were taken from different eco-geographical regions to assess genetic diversity and variability at both morphological and molecular level. Morphological characterization of different yield attributing characters were studied as plant height (cm), days taken to Ist flowering; 50% flowering; maturity, different seed, flower and fruit related traits. DSQUARE values was calculater by using GENRES software it was found that all the exotic genotypes and genotypes from northern part of India came in same cluster while, two genotypes of southern part of India came into separate cluster. Genetic diversity was also estimated at molecular level with the help of capsicum specific SSR markers. Further, scoring was done based on the presence or absence of bands in the gel picture and binary data was analyzed with the help of STATISTICA software. As a result, the genotypes were grouped into two major clusters; cluster I and cluster II contain 5 and 14 genotypes respectively and under the under two major clusters 5 minor cluster formed. Genotype EC 362980 belongs to Capsicum chinense and EC 121489 belongs to Capsicum baccatum were far apart in dendrogram indicating they were less relative to each other during course of evolution. The remaining genotypes used in the project study belongs to Capsicum annum came in-between those two species which showed they might have originated from Capsicum chinense and Capsicum baccatum
