The variety identification serves the important goals such as mitigating legal claims and confirming intellectual property rights and maintenance of genetic purity. Plant morphological characters are universally adopted descriptors for DUS testing and varietal characterization of crop genotypes. In this study 10 sugarcane cultivars (TNAU Sugarcane Si. 6, TNAU Sugarcane Si. 7, TNAU Sugarcane Si. 8, Co 86032, Co 99004, Co 99006, Co 94008, Co 94012, Co 2001-13 and Co 2001-15) were characterized using 27 morphological descriptors. Among the 27 descriptors, width of root band opposite to bud alone was monomorphic, 14 were dimorphic and 12 were found to be polymorphic. Distinct morphological profiles were obtained for four out of ten cultivars. The dendrogram based on UPGMA analysis using DUS characters, grouped ten sugarcane cultivars into two major groups at 43 per cent similarity level. The similarity matrix coefficient ranged from 43 per cent to 63 per cent with an average of 53 per cent.
