The suitability of nectarine and peach cultivars for organic production was examined in a field experiment in the experimental orchard of the institute in Vienna. Therefore, fifteen cultivars including Redhaven as standard cultivar were planted in 2003 and cultivated organically. Characteristics of the cultivars, such as blossom, growth, yield and susceptibility to frost damage and diseases (Taphrina deformans and Monilinia ssp.) were examined. Furthermore, fruit quality characteristics were checked in the laboratory. The results of growth, yield, susceptibility to damages and diseases and fruit quality showed significant differences among the cultivars. ‘Redhaven’, ‘Sweethaven’, ‘Redcal’, ‘Benedikte’ and ‘Mireille’ can be recommended for organic... |
