Neues Konzept für die ökologische Tomatenzüchtung Organic Eprints
Trotz steigender Nachfrage stagniert in Deutschland der ökologische Anbau von Tomaten. Ein zunehmendes Problem im geschützten Anbau ist die Samtfleckenkrankheit, verursacht durch den Pilz Passalora fulva (syn. Cladosporium fulvum). Der saisonale, kostengünstige Anbau unter Folie ist dabei besonders betroffen. Die als resistent ausgewiesenen Sorten geben in den traditionellen Anbaugebieten wie am Bodensee mit einer jährlich hohen Befallsgefahr keinen ausreichenden Schutz mehr. Ziel des Projektes ist es, ökologisch angepasste Sorten mit stabiler Resistenz und einem guten Geschmack zu entwickeln. Zum einen soll eine neue, auf das System angepasste Züchtungsstrategie (F4 Kreuzungsnachkommen) erprobt (1) und zum anderen durch reine Kreuzungszüchtung neue...

Novel organic solutions securing future growth Organic Eprints
Currently the Danish organic fruit & berry production area is 502 ha with the main crop being apples at 282 ha. FruitGrowth will address the main barriers identified by the ‘Working Group report, 2009’, by focussing on robust cultivars in apples, new innovative weeding methods and extending the fruit season & thereby product availability for consumers we will introduce new cultivars & technologies in storage. We work on short & long time solutions of the key pests & diseases (codling moth, apple sawfly & apple scab in apples), natural beneficial’s in flower strips, & natural compound to control key pest. FruitGrowth includes research, development, demonstration & dissemination of the results to fruit growers. Outcomes are...

Nutrient use efficiency and arbuscular mycorrhizal root colonisation of winter wheat cultivars in different farming systems of the DOK long-term trial Organic Eprints
Hildermann, Isabell; Messmer, Monika; Dubois, David; Boller, Thomas; Wiemken, Andres; Mäder, Paul.
BACKGROUND: For organic farming, cultivars are required with high nutrient use efficiency under nutrient limited conditions. Arbuscular mycorrhizal fungi (AMF) are known to contribute to nutrient uptake under low input conditions. We compared nutrient use efficiency (NUE) of old and modern organically and conventionally bred cultivars in organic and conventional systems and assessed AMF-root colonisation (AMF-RC) in relation to nutrient concentrations. RESULTS: Cultivars and systems had a statistically significant effect on nitrogen (N) and phosphorus (P) concentrations and NUE parameters, whereas no genotype × environment interactions appeared. In contrast to N and P uptake, the NUE parameters were higher under organic than under conventional...

Nutzbarmachung von Resistenzquellen gegen Flugbrand zur Verbesserung der Immunität in Sommergerste für den ökologischen Landbau Organic Eprints
Sommergerste ist im ökologischen Landbau nach Weizen, Hafer und Dinkel die Getreideart mit der höchsten Bedeutung für die verarbeitende Industrie. Voraussetzung für eine stärkere Verbreitung des Sommergerstenanbaus im ökologischen Landbau ist die Bereitstellung geeigneter Sorten. Für die Sommergerste (Braugerste und Futtergerste) sehen Vertreter der Ökolandbau-Beratung einen hohen Bedarf an Züchtung und Züchtungsforschung (Arbeitskreis Brot- und Braugetreidezüchtung im ökologischen Landbau der LfL, V.Ö.P, n.p.). Resistente Sorten haben im Ökolandbau besonders große Bedeutung. Insbesondere samenübertragbare Krankheiten wie der Gerstenflugbrand sind äußerst schwierig zu kontrollieren und stellen aufgrund ihrer Bedeutung für die Saatguterzeugung ein großes...

Nutzung genetischer Ressourcen der Europäischen Wildrebe für die Züchtung von Mehltau- und Schwarzfäule-resistenten Reben Organic Eprints
Nick, Peter; Kortekamp, Andreas; Eibach, Rudolf; Trapp, Oliver.
Zur Bekämpfung der Schwarzfäule werden im ökologischen Weinbau nach wie Kupfer- oder Schwefelpräparate eingesetzt. Als Alternative sollte das Potential der Europäischen Wildrebe (Vitis sylvestris) für die Resistenzzüchtung untersucht werden. Dies würde zum einen die natürliche Artbarriere respektieren und neue Resistenzquellen für eine nachhaltige Pyramidisierung erschließen. Grundlage war eine im Rahmen des BLE-Projekts „Überlebenssicherung der Wildrebe in den Rheinauen durch gezieltes in-situ Management“ im Botanischen Garten des KIT etablierte Sammlung von V. sylvestris, die nach derzeitigem Kenntnisstand die in Deutschland für diese Art noch vorhandene genetische Diversität vollständig abbildet. In dieser Sammlung waren Hinweise auf Resistenzen gegen...

Nutzung genetischer Ressourcen der Europäischen Wildrebe für die Züchtung von Mehltau- und Schwarzfäule-resistenten Reben (Verbundvorhaben) Organic Eprints
Das hier beschriebene Projekt ist Teil eines Verbundvorhabens, das folgende Teilprojekte umfasst: FKZ 10OE067, FKZ 10OE113, FKZ 10OE114. Alle in Organic Eprints archivierten Projektbeschreibungen und Veröffentlichungen zu diesem Verbundvorhaben finden Sie unter folgendem Link: http://orgprints.org/cgi/saved_search?savedsearchid=1359. Im ökologischen Weinanbau stellen Pflanzenkrankheiten wie der Falschen und Echte Mehltau, sowie die Schwarzfäule, ein großes Problem dar. Um chemische Pflanzenschutzmittel zu vermeiden werden als zentrale Schutzmaßnahme resistente Sorten angepflanzt, die meist auf Kreuzungen mit Amerikanischen Weinpflanzen zurückgehen. So konnten bereits gute Bekämpfungserfolge in Bezug auf den Falschen und Echten Mehltau erzielt werden;...

Nye vårbygsorter ser lovende ud Organic Eprints
Blume, Steffen.
Arealet med vårbyg blev i 2012 større end antaget, hvilket skyldes udvintring af vinterhvede og gulrust i triticale. Og da såsæden af andre vårsædsarter hurtigt blev udsolgt, måtte mange økologer nøjes med vårbyg. Generelt har vårbyg landet over givet gennemsnitlige udbytter og har således været det rigtige valg i forhold til en udvintret vinterhvede.

On farm Haferflugbrand Resistenzzüchtung auf dem Dottenfelderhof von 2005 bis 2012 Organic Eprints
Schmehe, Ben; Becher, Thorben; Spieß, Hartmut.
In 2005 an organic oat (Avena sativa L.) breeding programme was initiated by the on farm breeding and research institute at Dottenfelderhof, Hessen, Germany, with the purpose of releasing oat varieties suitable for organic agriculture. From the very beginning it was one goal to develop varieties resistant to loose smut of oat (Ustilago avenae), which can be a severe problem for the certification of seeds. Therefore registered varieties as well as gene bank accessions were used for crosses and evaluated for resistance to loose smut over the years. In this paper the selection process is being described and the resistant level of the present filial generations in 2012 is shown. Additionally the results of the evaluation of registered varieties from 2010-12...

Participatory potato breeding model involving organic farmers and commercial breeding companies in the Netherlands Organic Eprints
Lammerts van Bueren, E.T.; Engelen, Christel; Hutten, R.C.B..
Organic farmers urgently need cultivars resistant to Phytophthora infestans. Such cultivars also need to be adapted to other traits important for organic farming systems. One goal in the first five years of this ten-year, public-private partnership was to establish a program within the Dutch potato breeding system that includes farmer breeders working in close collaboration with six commercial breeding companies and two research institutes. To meet the goals we have involved 14 organic farmer breeders through setting up a yearly breeding course. A pre-breeding program is now running to introgress late blight resistance from wild relatives into cultivated material, and to make crossings with advances genitors to distribute seeds to farmer and commercial...

Pest and disease management in organic farming: implications and inspirations for plant breeding Organic Eprints
Döring, Thomas F.; Pautasso, Marco; Finckh, Maria R.; Wolfe, Martin.
The co-evolution of plants with their pests and diseases is a major driving force in evolution in nature. As a consequence, many pests and pathogens have multiple functions involved in survival on host populations. As a result of this continuous co-evolution, plant pests and pathogens have been selected for high reproduction rates, because of the low probability of an individual being able to find or infect a compatible host plant. For their part, host plants in natural ecosystems are often interspersed among other plant species and show wide and changing variation among individuals for genes affecting specific or non-specific resistance to each of the many pathogens that may attack them. Throughout the plant world there are dynamic and unstable equilibria...
