The experiment was established in the spring of 2004 in the Experimental Ecological Orchard in Nowy Dwór (central Poland). The suitability of sour cherry trees for organic production was assessed in terms of tree growth, yielding, fruit quality and tree health status. Sixteen cultivars were evaluated: ‘Oblacinska’, ‘Lucyna’, ‘Wanda’, ‘Stevnsbaer’, ‘Elmer’, ‘Pamiat Wawilowa’, ‘Wlodzimierska’, ‘Naumburger’, ‘Slupia Nadbrzeżna’, W 1/02, W 2/02, W 7/02, W 8/02, W 9/02, W 10/02 and W 12/02. The trees grafted on Prunus mahaleb seedlings were planted at a spacing of 4.5x 2.5 m, in four replications with three trees per plot, and were trained in the spindle form. Plant protection was based on cuprum and sulphur. The trees were irrigated. Preliminary results show that the most interesting sour cherry cultivars for ecological orchards are the hybrid W 12/02, and also ‘Stevnsbaer’, ‘Słupia Nadbrzeżna’ and W 10/02. The cultivar ‘Elmer’ is not recommended for ecological fruit production.
