Hazelnut Cultivars Suitable for Northwest European Conditions

Abstract

Hazelnut cultivar evaluation in the maritime climate of northwestern Europe revealed that cultivars from northern or southern origin may produce on average good crops of high quality. Production was, however, irregular. Ten cultivars out ot 47 tested performed satisfactorily tor both yield and nut quality: ‘Gustav's Zeller’ (Germany); Tauetet’ (Spain); Mortarella’, ‘Tonda di Giffoni’, and ‘Riccia di Talanico’ (Italy); ‘INRA H105-28’ (France); and ‘Willamette’ (Oregon). ‘Negret’ (Spain) cropped just below the desired level, but had good nut quality. Three new Dutch selections (‘Emoa’ 1, 2, 3) also performed well. Some cultivars were sufficiently productive, but their kernels blanched poorly; ‘Gunslebert’ (Germany), ‘Lane Tidlig Zeller’ (Denmark), ‘Butler’ (USA) or very poorly during roasting; ‘Impératrice Eugénie’ (England) and ‘Longue d'Espagne’ (probably of English origin).
