Grapevine Scion-Rootstock Combination of Palestinian Local Cultivars and Rootstocks resistant to grape Phylloxera, Dactolosphaira vitifoliae (Fitch) [Phylloxeridae: Homoptera]

Abstract

Grapevine-rootstock experiment was carried out in 2006 at Hebron University, Palestine. The experiment included a set of clonal-scions of five local cultivars (Vitis vinifera L.) namely: Shami, Beitoni, Darawishi, Masri, and Hamadani-Faransi, grafted on to five rootstocks resistant to grape phylloxera namely: Richter-110, Paulsen-1103, Ruggeri-140, B41, and 216/3, in addition to un-grafted vines as control treatment. The grafting was done using tongue grafting indoor technique. All grafted plants showed excellent percentage of grafting success after ten weeks in the incubation room with almost 100% success. Positive correlations were found between callus development and graft success in the nursery. After five months in the nursery, Shami and Masri cultivars demonstrated high compatibility while Beitoni and Hamdani-Faranse cultivars showed intermediate level of compatibility, but Darawishi cultivar showed poor compatibility with all tested rootstocks.
