| Pea (Pisum sativum L.) belongs to the legume family (Fabaceae). Legumes form mutualistic symbiosis with nitrogen fixing rhizobacteria and, thereby, are able to improve soil fertility. Legume crops are important protein source for food and feed and contribute to the nitrogen demand of succeeding crops. Despite their importance, cultivation of cool-season legumes in temperate zones remains below expectations due to low and unstable yields. Soil fatigue is caused by a complex of different soil-borne pathogens and thought to be the main reason for yield losses, especially in pea. Plants have the ability to actively shape the community of root associated microbes through root exudations. Evidence is growing that there is considerable genetic variation for plant... |

| Einleitung und Problemstellung Anthracnose (Colletotrichum trifolii) hat in den letzten Jahren als Krankheit an Rotklee an Bedeutung gewonnen. Diese Pilzkrankheit kann zu einem erheblichen Verlust von Rotkleepflanzen in Rein- und Mischbeständen mit Gräsern führen. Falls es zu einem vermehrten Auftreten dieser Krankheit auf landwirtschaftlich genutzten Flächen kommt, wäre der Einsatz von Sorten mit einer hohen Resistenz ein vielversprechender Ansatz, um die Grundfutterversorgung, aber auch die Stickstoffversorgung v.a. ökologisch wirtschaftender, viehloser Betriebe abzusichern. Durch die Züchtung von resistenten Sorten spielt die Krankheit bei Rotklee in den USA nur noch eine untergeordnete Rolle. In der vorliegenden Untersuchung sollte geprüft werden, ob... |

| Utilising diverse populations instead of single line varieties is expected to lead to a number of advantages in cereal production. These include reduced epidemics of plant diseases, improved weed competition and better exploitation of soil nutrients, resulting in improved yield stability. However, a number of challenges must be met before diverse wheat populations can be introduced into commercial wheat production: one of these is the development of breeding technologies based on mass selection which enable breeders and farmers to improve specific traits in populations and maintain diversity at the same time. |

| 15 wheat and 4 spelt varieties suitable for ecological farming have been cultivated and tested for susceptibility to common bunt of wheat (T. caries). The 2-years randomized field trials have been carried out at 1 site, with 4 replicates and 10 m row length on naturally infested fields with T. caries. Sowing, weed control and harvesting was done by hand. The number of infested ears has been counted and the number of spores per kernel or spelt has been determined according ISTA. The infestation by wheat of the highest (Elixer, Meister) and lowest (Butaro, Florian) susceptible wheat varieties was higher than 10,000 and lower than 1,000 spores per kernel, respectively. The four spelt varieties had the lowest infestation significantly below 100 spores per... |

| Disease resistance is not a mere plant but a system trait involving the complex plant-associated microbial community (Berendsen et al. 2012). As with pathogens, past research often focussed on single, culturable symbiotic microbes. More recently, microbial shifts on the community level have been linked to disease resistance. However, simplistic statements such as “high microbial diversity equals healthier plants” were not confirmed in most recent microbiome analyses (Hartmann et al. 2014, Yu et al. 2012). Plants have the ability to influence the microbial structure in the rhizosphere. Besides soil type, it has been demonstrated that not only different plant species, but also different genotypes within the same species can modify the rhizosphere microbiome... |

| Ziel des Projektes war, Zuchtpopulationen bzw. traditionelle, offen blühende Brokkoli-Sorten (keine Hybriden bzw. CMS-Hybriden) speziell für den Ökologischen Landbau zu prüfen. Wichtige Eigenschaften waren dabei Ertragssicherheit, Einheitlichkeit, enges Erntefenster, Festigkeit der Blume sowie hohe Gehalte an sekundären, bioaktiven Inhaltsstoffen, insbesondere von Glucosinolaten. Um eine schnelle und kostengünstige Möglichkeit zum Screening von bioaktiven Inhaltsstoffen zu entwickeln, die für den On-Farm-Einsatz geeignet ist, wurde zudem ein zerstörungsfrei arbeitendes Sensortool getestet. Während der dreijährigen Projektlaufzeit erfolgten On-Farm-Selektionen geeigneter Brokkolilinien/-sorten auf Kultursaat-Zuchtstandorten sowie auf der Versuchsstation für... |

| Das hier beschriebene Verbundvorhaben umfasst folgende Teilprojekte: FKZ 11NA056, FKZ 11NA093. Alle in Organic Eprints archivierten Projektbeschreibungen und Veröffentlichungen zu diesem Verbundvorhaben finden Sie unter folgendem Link: http://orgprints.org/id/saved_search/1548. Ziel dieses Projekts ist die Aufklärung der molekularen Regelmechanismen und die Erarbeitung molekularer Marker für die Lockerbeerigkeit der Weinrebe zur Anwendung in der Marker-gestützten Rebenzüchtung. Lockerbeerigkeit ist ein wichtiger physikalischer Resistenzfaktor gegen den ubiquitären Pilz Botryotinia fuckeliana ("Botrytis") und weitgehend durch die Architektur des Fruchtstands bedingt. Lockerbeerige Rebsorten sind deutlich weniger anfällig gegen dieses Pathogen als... |

| Somatic embryogenesis (SE) is the most striking and prominent example of plant plasticity upon severe stress. Inducing immature carrot seeds perform SE as substitute to germination by auxin treatment can be seen as switch between stress levels associated to morphophysiological plasticity. This experimental system is highly powerful to explore stress response factors that mediate the metabolic switch between cell and tissue identities. Developmental plasticity per se is an emerging trait for in vitro systems and crop improvement. It is supposed to underlie multi-stress tolerance. High plasticity can protect plants throughout life cycles against variable abiotic and biotic conditions. We provide proof of concepts for the existing hypothesis that alternative... |

| Organic production requires novel, robust cultivars especially for crops such as apple, grape, tomato and potato which are very disease susceptible and are often protected by copper compounds. The European project CO-FREE aims to develop innovative methods, tools and concepts for the replacement of copper to reduce the use of copper in organic farming systems. One key strategy is the introduction of resistant cultivars. However, previous studies have shown that the introduction of novel cultivars often meets substantial obstacles as retailers’ and/or consumers’ awareness has to be generated in order to open the market. Resistance is an important issue for farmers but not immediately appealing for consumers as they are hardly aware of the fact that current... |

| Ziel des Vorhabens ist es, die Anbauwürdigkeit und Ertragssicherheit von Gelben und Weißen Lupinen zu steigern. Neben der Verbesserung der Krankheitsresistenz (Anfälligkeit gegenüber Anthraknose) wird eine Erhöhung der wertgebenden Inhaltsstoffe (z. B. Proteingehalt), und eine Verminderung der werthemmenden Inhaltsstoffe (z. B. Bitterstoffgehalt), angestrebt. Weitere Ziele sind die Selektion auf die Merkmale Frühreife und hoher Ertrag. Es werden Methoden zur Prüfung der Resistenz gegenüber Anthraknose von der Blauen Lupine auf die Gelbe und Weiße Lupine übertragen. Zur Ermittlung der Frühzeitigkeit und Erfassung von Ertragsdaten werden dreijährige Feldversuche auf drei ökologischen Standorten durchgeführt. Für eine beschleunigte Züchtung auf... |
