In Austria the demand for organic products increased highly in the last few years. New challenges concerning the potato breeding are developed caused by the consumers who make higher demands on the quality of the products. In Austria the organic multiplication of potatoe seeds is produced since 1996. My thesis deals with the evaluation of the criteria which are playing a fundamental role in the organic farming. The criteria are related to the culture of potatoes. I have chosen the following criteria: emergence, cabbage growth, soil cover, beetle infestation and phytophthora infestation. The evaluation concentrates on three locations with conventional farming (Aderklaa, Untermallebarn and Sparbach) and two locations with organic farming (Meires and Naglern). These locations are situated in Lower Austria and are numbered among the most important regions for the cultivation of potatoes. The emergence and the cabbage growth were evaluated in the organic farming as well as in the conventional farming. The soil cover, the beetle infestation and the phytophthora infestation were just rated in the locations with organic farming. In consideration of the criteria which have been mentioned, there´s a significant difference between the locations and the years within the evaluation took place. Differences can also be seen between the varieties and clones. In the organic farming, the date of emergence impacts the harvest of tuber yiels and starch yield immensely. This fact doesn´t apply to the conventional farming. There, cabbage growth, soil cover, beetle infestation, phytophthora infestation impact the harvest of tubers and starch immensely. As expected, by comparison the conventional farming could reach a higher harvest of tubers.
