The aim of this thesis was to determine the possibilities of improving the organic sweet cherry production under pannonic climate conditions. For this purpose numerous vegetative and generative parameters of 13 cultivars were evaluated during the growing season of 2009 in a trial orchard of the University of Natural Resources and Life Sciences (BOKU) in Vienna. In addition, fruit quality analysis was performed on six of the cultivars in the laboratory of the Division of Viticulture and Pomology of the BOKU. Finally, three taste test events were organised among the BOKU students. Also, effects of fruit thinning induced by pruning during blossom were evaluated, as well as different strategies for controlling European Cherry Fruit Fly (Rhagoletis cerasi L.). The results have shown that the cultivars ‘Bigarreau Burlat and ‘Merchant provide favourable yields and good fruit quality under the given climatic and soil conditions. The cultivar ‘Bigarreau Moreau can also be recommended for organic growth, although it lacks a higher specific yield. These three cultivars were very well liked by consumers during the taste test events. The fruit quality analysis during three different ripening stages indicate that there are differences between the cultivars in all of the 14 evaluated parameters, at times between the ripening stages as well. Fruit thinning induced by pruning during blossom has reduced yield with no positive effects on the fruit size or quality. The fruits of the early ripening cultivars (1st and 2nd harvest week) have contained no Cherry Fruit Fly larvae, while the fruits of ‘Merchant (beginning of the 3rd harvest week) have contained less than 2% (marketing tolerance threshold) of the larvae. The later ripening cultivar ‘Sweetheart (6th harvest week) has shown infestation levels of over 40%. Application of Cherry Fruit Fly's natural enemy Beauveria bassiana, in order to bring the pest under control on later ripening cultivars, provided no noteworthy results.
