The experiment was carried out in an experimental vineyard which ispart of Embrapa Semi-Árido, city of Petrolina, Pemambuco State, during 1997 and 1998.The varieties tested were Vênus, Arizul, Beauty Seedless, Thompson Seedless, MarrooSeedless, and Canner grafted on IAC 572 ('Jales') rootstock. The experimental modelutilized was tota11y randomized with parcels subdivided into different production cycles.The results shown significative differences among varieties at different pruning times. Allvarieties presented small bunches. The berries of 'Vênus' and 'Marroo Seedless' showedaverage diameters of 17.83 and 18.26 mm. The total soluble solids (SST) was high inmost varieties. However, the total titulable acidy (ATT) was low. The ratio (SST/ATT)varied from 19.05 in 'Beauty Seedless' to 28.57 in 'Vênus'. 'Vênus' and 'MarrooSeedless' were the most productive varieties, with the average annual production of 24 tIhaand 20 t/ha, respectively.50
