DhawanAbstractCymbopogon is an aromatic grass belongs to Poaceae family. To detect the polymorphism among seventeen accessions of Cymbopogons for genetic diversity in total, 20 RAPD primers and 16 microsatellite primers were used. 18 RAPD and 14 ISSR primers responded well and provided reproducible polymorphism 81.3% and 87.4%. PCs were able to explain 79.2% of the total variability. The Mantel test shows strong significant correlation (r = 0.80) between two similarity matrices calculated using both molecular analysis systems. Different species of Cymbopogon showed many variations in essential oil yield (0.4%–1.4%) as well as GC and GC/MS analyses for the identification of many constituents like neral, geranial, citronellal and geraniol. The present study was successful in predicting genetic and chemical diversity of the population of Cymbopogons.
