Sweet cherries are grown in areas with suitable local climatic conditions up to 60°N in Norway. All orchards have high density planting systems and are rain covered from the bloom to the end of the harvest. All orchards are fertigated and the production is aimed to supply the domestic market with high quality fruit from early July and to the end of August. At NIBIO Ullensvang a large number of sweet cherry cultivars and advanced selections from worldwide breeding programs have been evaluated continuously since 1959. However, despite of relatively extensive list of recommended cultivars, cv. 'Lapins' has become dominant with 60% of the total sweet cherry volume in Norway, and causes high pressure in the market when too much fruit are delivered at the same time. The most effective way to extend the cherry market season is an introduction and cultivation of new early or late ripening sweet cherry cultivars. During the last years, approximately fifty cultivars and advanced selections have been evaluated. Along with earlier recommended cultivars ‘Folfer’, ‘Van’, ‘Lapins’, ‘Regina’ and ‘Sweetheart’, the following cultivars can be recommended for extended testing commercially: a) for early season: ‘Adelka’ (for local market), ‘Sweet Aryana’ and ‘Bellise’ (primary for local market), b) for mid-season: ‘Edit’, ‘Brooks’ (limited testing) and ‘Grace Star’, c) for late season: ’SPC 342’, ‘LaLa Star’, ‘Royal Edie’, ‘Tamara’ and ‘Royal Helen’.

Sweet cherries are grown in areas with suitable local climatic conditions up to 60°N in Norway. All orchards have high density planting systems and are rain covered. The most common system now is multibay high tunnels systems where the trees are under plastic cover from the bloom to the end of the harvest. All orchards are fertigated and the production is aimed to supply the fresh fruit domestic market with high quality fruit from early July and to the end of August. At NIBIO Ullensvang, western Norway a large number of sweet cherry cultivars and advanced selections from worldwide breeding programmes have been evaluated continuously since 1959 and several cultivars have been recommended from this programme for commercial production during the last decades. During the last six years approximately fifty cultivars and advanced selections grafted on the rootstock Gisela 6 have been tested. Important objectives were to obtain large and precocious yields, with important quality parameters like fruit size, fruit firmness, soluble solids, fresh appearance, good flavour and resistance against irrigation induced cracking. Based on the results from the recent testing program, the following cultivars are currently recommended for the fresh fruit market: a) for early season: ‘Adelka’, ‘Pacific Red’, ‘Sweet Aryana’ and ‘Bellise’, b) for mid-season: ‘Brooks’, ‘Giant Red’, ‘Grace Star’ and ‘Folfer’ c) for late season: ‘Van’, ,’SPC 342’, ‘LaLa Star’, Royal Edie’, ‘Tamara’ ‘Lapins’, ‘Royal Helen’, ‘Regina’ and ‘Sweetheart’.
