Abstract Molecular diversity in Saccharum complex was studied using 195 RAPD markers generated by 12 random primers. Among the Saccharum species, S. officinarum showed a low level of genetic diversity while S. sinense was found to be more diverse. Six taxonomical groups were clearly resolved in the cluster analysis. S. officinarum, S. robustum, S. spontaneum and Erianthus spp. formed discrete groups. S. barberi and S. sinense formed a single cluster, so also Narenga and Sclerostachya. S. officinarum was found to be closer to S. robustum and distant from S. spontaneum. Among the related genera, Sclerostachya was closer to Saccharum while Erianthus was found to be highly divergent from all the Saccharum species. Six of the primers used generated RAPD fragments unique to Erianthus. It is suggested that the Erianthus spp. can contribute substantially towards sugarcane varietal improvement in view of its greater divergence with Saccharum.
