Entwicklung von Phytophthora-resistentem Zuchtmaterial für den ökologischen Landbau
Provedor de dados: 21
Autores: Forster, Georg; Sieber, Karen; Schwarzfischer, Andrea; Kellermann, Adolf.
Insbesondere im ökologischen Kartoffelanbau stellt die Kraut- und Knollenfäule, hervorgerufen durch den Erreger Phytophthora infestans, ein großes Produktionsrisiko dar. Der Pflanzenzüchtung obliegt die Aufgabe Sorten bereit zu stellen, die sowohl durch überdurchschnittliche Toleranz als auch Resistenz gegenüber dieser Krankheit eine besonders gute Eignung zum Anbau haben. Über das Bundesprogramm „Ökologischer Landbau und andere Formen nachhaltiger Landwirtschaft“ (BÖLN) fördert das Bundesministerium für Ernährung und Landwirtschaft ein Verbundprojekt, in dem durch die Bündelung der deutschen Fachkompetenz dieser Aufgabenstellung züchterisch begegnet wird. Die Kooperationspartner entwickeln zusammen unter Inanspruchnahme einer breiten Pflanzendiversität,...

Genetische Analyse der Feldresistenz von Kartoffeln gegenüber  der Krautfäule im ökologischen Landbau

Late blight, caused by the oomycete Phytophthora infestans (Mont de Bary) poses one of the most important risks in production of organic potatoes. Favourable late  blight conditions result in substantial losses in yield and quality in susceptible genotypes. In a series of field experiments between 2012 and 2015 at three organic  sites in northern and southern Germany 148 cultivars assessed the outcome of decades of german late blight resistance breeding. The phenotyping of this diversity  panel under natural conditions showed significant differences in the level of resistance within and across all maturity classes. These results were then used for a Single  Nucleotide Polymorpism (SNP) assay on a 12k Infinion chip to locate QTLs for late blight resistance....

Under organic farming conditions late blight, caused by Phythophtora infestans, poses one of the highest production risks. Extensive plant breeding activities are needed to offer varieties which show higher resistance to this potato disease. For organic farming cultivars are required to thrive under reduced pest management and increased mechanical stress. To meet these demands the German Federal Ministry of Food and Agriculture has promoted a joint research project funded through the “Federal Organic Farming Scheme and other forms of sustainable agriculture” (BÖLN). The project brings together the German expertise in potato breeding: the Julius Kühn–Institut (JKI), the Leibniz-Institut für Pflanzengenetik und Kulturpflanzenforschung (IPK), the Bayerische...

Kartoffelzüchtung für den ökologischen Landbau Wege in die Zukunft
Provedor de dados: 21
Autores: Sieber, Karen; Forster, Georg; Schwarzfischer, Andrea; Kellermann, Adolf.
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...
