Effect of Some Rootstocks on the Performance of Flame Seedless Grapevines

Grape (Vitis vinifera L.) is considered one of the most important and popular fruit crops in the world, especially in temperate, tropical, and subtropical regions. In Egypt, grapes are one of the most widely grown fruit crops. Egypt’s grape cultivation is spread geographically from the north to Aswan to the south, which, combined with the production of early and late-ripening grapes varieties, enables to prolonged availability of fresh table grapes to local consumption and exportation from May to November every year. The production of grapes in Egypt increased as a result of introducing several new varieties, rootstocks, and improved cultural practices, post-harvest treatments of storage as well as new marketing methods and exportation. Egypt ranks fourth worldwide in the global production volume of table grapes and has shown impressive growth in the past 5 to 10 years. In 2016, production of grapes in Egypt amounted to 1 691 194 tones on 184 254 feddan of cultivated land (Nakai, 2018).
