This study was carried out during two successive seasons, 2006 and 2007 in order to find out the optimum number of buds to be left on the vines of superior grapevines to get the highest possible yield with the best fruit quality besides maintaining vine Vigor. Severn years – old – uniformed vines chosen and pruned to seven different levels of bud load, namely, 77, 84, 91, 98, 105, 112 and 119 buds/vine. The results of this investigation showed that the percentages of busted buds and fruitful buds decreased with increasing the bud load/vine, while the fertility coefficient was not affected by pruning level in both seasons. Increasing of bud load/vine increased number of bunches but decreased yield/vine. In addition, increasing bud load on the vine significantly decreased bunch weight, bunch length, bunch index, rachis weight, berry weight, berry firmness, number of berries/bunch, T.S.S. and T.S.S / acid ratio while, Total acidity % increase as bud load increase Acidity was increased .While, wood ripening and on the other hand wood ripening and total carbohydrates decreased by increasing bud load/vine. Results also showed that 98 or 105 buds/vine is more suitable for superior grapevines to produced good yield and fruit quality.
