Six exotic varieties of sugarcane (CP84-1198, CP85-1491, CP88-1165, CP77-400, CP89-846, TCP86-3368) planted at the National Agricultural Research Centre during 1998-99 were described for their morphological characters. All the varieties greatly varied in different characters. Mean leaf length, number of green leaves and width of leaf lamina/blade was different in different varieties. These varieties also differed in leaf sheath colour, carriage, and other leaf characters. Shape of the dewlap, its size and colour, shape of ligule and ligular process or auricle was also different. All the varieties varied in diameter of the stalks, colour of the stalks, shape of internode, bud groove characters, width and colour of growth ring, width and colour of root zone and wax band characters. Ivory markings were present on stalks of all the varieties. All the varieties were similar in bud size, but different in shapes of the bud, some having flanges and some without flanges. Position of the germ pore on the bud was also different in all the varieties.
