Description: Das Projekt "Freezing tolerance of genetically enhanced amylopectin starch potatoes (event AV43-6-G7) (BASF Freezing)" wird vom Umweltbundesamt gefördert und von Leibniz-Zentrum für Agrarlandschaftsforschung (ZALF) e.V., Institut für Landschaftsbiogeochemie durchgeführt. Tubers of commonly grown potatoes (Solanum tuberosum L.) that remain in the field after the harvest are normally killed by temperatures of below -3°C. However, the recent absence of severe winters has allowed potatoes to survive the cold season and to multiply at a prolific rate. The volunteers are hosts for many potato diseases and compete with rotational crops for light, water and nutrients and hence are controlled through an integrated management approach. Modifications by conventional breeding or a transgenic approach may influence ecological parameters such as the frost tolerance and the tubers' ability to develop volunteer potatoes. The objective of the study was to evaluate the freezing tolerance of a transgenic 'amylopectin potato' in comparison to the isogenic control and two reference varieties. The frost hardiness of the tubers was tested in climate chamber experiments under different frost regimes.
