This study was designed to select the best summer pruning practice for Red Roomy grapevines that achieve an economical yield and berries with good quality. Four techniques namely head suckering, pinching the main shoots and maintaining laterals, pinching the main shoots and topping the laterals as well as pinching the main shoots and removing the laterals were carried out. In addition, the experiment involved the vines that were left without summer pruning (as control).        The results showed that all summer pruning treatments substantially seemed to be very effective in improving growth aspects, cane total carbohydrates %, coefficient of wood ripening, berry set %, yield as well as physical and chemical properties of the berries compared with leaving the vines without summer pruning. Head suckering followed by pinching of the main shoots and maintaining laterals resulted in great stimulation on all the studied parameters. No pruning during summer on the other hand recorded the minimum values of these characters.                 For inducing vigorous vines and improving both yield and fruit quality of Red Roomy vines it is necessary for carrying out summer pruning practice by head suckering or pinching the main shoots and maintaining laterals. This study confirmed the beneficial of carrying out summer pruning for such grape cv.
