Advances in Hazelnut (Corylus avellana L.) Rootstocks Worldwide

Studies on hazelnut (Corylus avellana L.) rootstocks have been limited to date. However, the use of vigorous, non-suckering for this species could increase cost-effectiveness orchards by reducing annual need prune suckers, thus facilitating mechanical harvesting, and orchard management costs environmental impact. Seedlings Turkish tree hazel (C. colurna used traditionally in Serbia. In 1970s, United States Department Agriculture Corvallis, Oregon (USA) released first two clonal rootstocks—‘Dundee’ ‘Newberg’—from open-pollinated seeds C. colurna. Moreover, selection cvs. with few suckers is continuing. Trials carried out different countries own-rooted grafted plants shown good performance hazelnuts. Currently, some nurseries several are propagating grafting trees planting commercial orchards. Interest these cultivar/rootstock combinations increasing, more new expected be planted coming years.
