Abstract: A functional, reliable and simple classification based on cormel flesh colour, cormel skin texture and petiole colour was developed and applied to 83 tannia clones collected in five islands of the Eastern Caribbean. Eleven elite tannia cultivars were identified which fell into three categories. I. white flesh/rough skin/green petiole 2. white flesh/smooth skin/green petiole 3. purple flesh/smooth skin/purple petiole The elite cultivars will serve the short-term improvement needs of. tannia cultivation through their multiplication and distribution. The data on the entire collection can be utilised in longterm genetic improvement programmes. ----- Una cfasificacidn funcional, honesta y simple basada en el color de la pulpa del brote, la textura de la cascara del mismo y el color de peciolo, fue desarrollada y aplicada a 83 clones de ocumo, recogidos en cinco islas del Caribe Oriental. Once cultivates selectos de ocumo fueron identificados y ellos se encuentran clasificados en tres categorias: I. pulpa blanca/cascara rugosa/peciolo verde 2. pulpa blanca/cascara lisa/peciolo verde 3. pulpa morada/cascara lisa/peciolo morado Los cultivares selectos serviran a la necesidad de tener un mejoramiento a corto plazo, del cultivo del ocumo, a travez de su muitiplicaci6n y distribucidn. Los datos de toda Ia colecci6n pueden ser utilizados en prograrnas, a largo plazo, del mejoramiento genetico.
