The present investigation was carried out for two successive seasons 2003 and 2004, with the aim of evaluating four grape cultivars, two seedless: Crimson and Fantasy, and two seeded: Christmas Rose and Red Globe. These cultivars were grown in a private vineyard at El-Sadat region ~Monofia governorate, Egypt Morphological studies included; time of bud burst, growing shoots, growing tip, 'nternodes, leaves, tendrils, flowering time, bunches and berries, seeds, TSS. acid ty. TSS/acid ratio. ripening date and bud fertility All studied cultivars were characterized by good vegetative growth and bunch quality. The average bunch weight was medium in Crimson and Fantasy cvs, big in Christmas Rose cv, while, it was very big in Red Globe cv. Berry weight and size were large for all cultivars except Red Globe cv, which was very large. Berry shape was cylindrical in Crimson and Fantasy cultivars. obovoid in Christmas Rose and rounded spherical in Red Globe cv. Berry colour was bright red in Crimson seedless cv., light red in Christmas Rose. bright pinkish red in Red Globe while, in Fantasy it was bluish black, Crimson was found to be the highest vigorous cultivar. while the Red Globe was the lowest vigorous one Ripening date of Crimson occurred in the first week of Aug. while in Christmas Rose it took place through the first week of Sept, for Fantasy it occurred at the last week of Aug Coefficient of bud fertility increased gradually from the basal buds to the middle buds of the cane where it reached its maximum then decreased gradually towards the distal buds in all studied cultivars. From the foregoing results, it can be recommended to prune Crimson and Fantasy cultivars according to cane pruning system while Christmas Rose and Red Globe cultivars can be pruned according to spur pruning system.
