Watermelon cv. Aswan F1 was grafted onto five rootstocks, viz; 6001 F1 , Strongtosa F1 , Tetsukabuto F1 , Ferro F1 and Shintoza F1 in three field experiments. Results of the first experiment showed that the highest growth and fruit yield were induced by 6001 F1 rootstock using tongue approach method. In the second experiment, Tetsukabuto F1 produced higher growth, while both rootstocks had higher fruit yield. In the third experiment, grafted plants onto 6001 F1 and Shintoza F1 gave the highest plant growth and fruit yield.
