Kartoffelzüchtung für den ökologischen Landbau Wege in die Zukunft

Summary

Most crop varieties which are used in organic farming are developed for and under conventional farming techniques. These cultivars may then be tested and used for
organic production. Between 2012 and 2018 the German Federal Ministry of Food and ew potato varieties under organic farming conditions. A great variety of modern cultivars is used to combine quality traits with the late blight resistance of pre-breeding clones from the Julius
Kühn-Institute. To optimize results all breeding clones are grown and selected on organic farmland where they have to thrive under reduced nitrogen levels, mechanical
weed reduction and high late blight pressure. Here we present results and practical experience from a participative approach where farmers are directly involved in the selection process.
