Using molecular markers one can examine genetic diversity of species, cultivars, lines and forms of sunflower, identify genotypes, systematize collection material, classify heterosis groups and construct genetic maps. Fourteen parental genotypes of sunflower viz.,CMS-2A, CMS-821A, CMS-850A, R-10-46-2A, CMS-A4, CMS-A6, CMS-A10, R-GM-39, R-GM-41, R-GM-49, R-GM-69, 83-Br, R-393 and R2F01120B were analyzed for genetic diversity using 15 RAPD and 44 SSR primers. The genetic similarity index computed considering pooled data of SSR and RAPD markers showed very wide range from 0.18 to 0.74 indicating high variability among 14 sunflower genotypes. The dendrogram separated 14 sunflower genotypes into four main clusters. The first cluster A having genetic similarity index of 0.64 included three sunflower genotypes (CMS 2A,CMS 821 A and CMS A4) indicating the narrow genetic base, however cluster B showed sufficient genetic diversity among four sunflower genotypes R-GM-49, R-GM-69, R-GM-41 and R-393 as these restorer lines have been derived from different genetic background.
