English. The aim of the present work is the characterization of six olive-tree varieties (Olea europaea L) - Azeiteira, Macanilha, Conserva de Elvas, Picual, Cobrancosa and Cordovil de Serpa - in the region of Castelo Branco. The similarities and difference between vegetative and productive characteristics of every variety were studied in 1997. The biometric parameters of fruits and leaves were also analysed. The olives were harvested when the ripening index was higher than 2.6. Yield indexes were determined and olive oil was obtained using an Abencor equipment. The fatty acid composition, acidity and UV absorbance of the olive oils were determined. The variety Cobrancosa showed the best productive characteristics as well as high fat content and good quality olive oil
