Descriptive account of sugarcane (Saccharum spp.) cultivar in cultivation, landraces and wild species is fundamental to breeders, researchers and growers for practical and scientific purposes and for the protection of new varieties. A preliminary botanical and agronomical characterisation form was initially developed based on that of Skinner (1972), but with some necessary modification. Additional characters were considered based on International Union for the Protection of New Varieties of Plants (UPOV, 1998). The descriptor form is based on description of morphological traits and growth characters like stool habit, tops, trashing, drought index, leaf blade and sheath, auricle, dewlap, ligule, internode, node and bud. Twenty six clones of sugarcane varieties were characterised using the preliminary form. The characterisation was conducted during the months of June and July of 1997, when the plants were 10 to 14 months old. Simple tools, figures and a colour code were used in this characterisation. Further improvement to the descriptor form was then considered, and upgraded form model was finally constructed and reported herein. This descriptor model includes a wide range of sugarcane genetic characters considering a rating scale with appropriate intervals to ensure high precision for the identification of clones and their variants, while the model remains flexible for taylor-made modifications.
