| Infection of wheat seeds with Fusarium spp. causes seedling blight. As a result of this disease, fields sown with infected seeds show a reduced plant density. This is especially a problem in organic agriculture, for which currently no practical seed disinfection methods are available. In the present project we investigated whether spring wheat cultivars differ in sensitivity to seedling blight, whether the possible differences could be linked to cultivar differences in early growth rates, and what size the delay in canopy closure resulting from the plant reductions was. Six spring wheat cultivars (Melon, Lavett, SW Kungsjet, Epos, Pasteur, Thasos), containing three infection levels (averages 5, 15 and 27%) of Fusarium culmorum were obtained and were sown... |

| Organic farmers must use organic seed material if such seed are available. If not available, conventional seeds can be used. This request exists in all accredited standards for organic farming. In the EU-regulation on organic production methods, the derogation from the use of organic seed material will only exist until the end of 2003. After this date only organic seed material may be used according to the present formulation. Only a few countries in the EU have an organic seed production able to supply the market for organic seed material. It takes many years to develop a well functioning market for organic seeds. It is therefore unlikely that the derogation for the use of organic seed material will not be extended, since a majority of countries in the... |

| The breeding research of pea (Pisum sativum L.) and faba bean (Vicia faba L.) crops began in 2013 because of priority for these species to be produced organically in Turkey. Nurseries were set up to cultivate landraces of pea and faba bean for regeneration, multiplication and observation of agro-morphological characters in autumn season (November 2013) at Organic Open Field Experimental Area of Aegean Agricultural Research Institute (AARI) located in the Mediterranean Region. Cowpea (Vigna unguilucata L.) and soybean (Glycine max L.) trials were also included by AARI for comparing grain legume crops of organic breeding programme of COBRA (Coordinating Organic Plant Breeding Activities for Diversity) project. For this purpose, nurseries of pea (24... |

| Two experiments were conducted in 14 spring barley cultivars to investigate if crop tolerance to post-emergence weed harrowing is related to morphological traits that reflect competitiveness. The experiments were carried out in organically grown fields where low weed densities and biomass production were assumed to be without significant influence on crop growth. The experiments showed that different cultivars responded differently to post-emergence weed harrowing in terms of yield reduction. Taller and higher yielding cultivars with high LAIs tended to be less tolerant to post-emergence weed harrowing than shorter and lower yielding cultivars with low LAIs. This conclusion, however, is only valid for 13 out of 14 cultivars because one very tall cultivar... |

| Alte Kartoffelsorten In der Schweiz wurden früher diverse Landsorten von Kartoffeln angebaut, welche heute fast vollständig vom Markt verschwunden sind. Die Stiftung Pro Specie Rara widmet sich der Erhaltung alter Kurturpflanzen und Nutztierrassen. Im Rahmen des Projektes "Beschreibung, Sanierung und Nutzung alter Kartoffelsorten" (NAP 02-53) untersucht das FiBL die Anbaueignung ausgewählter alter Kartoffelsorten im Bioanbau. Untersucht werden einerseits Anbaueigenschaften wie Krankheitsanfälligkeit und Ertrag, und andererseits Qualitätsaspekte wie Aussehen, Geschmack und Lagerfähigkeit der Kartoffelknollen. Ziel ist es, die interessantesten alten Kartoffelsorten wieder auf den Markt zu bringen. |

| ORGSEED undersøgelserne viser, at der findes en række vårbygsorter med lovende resistens overfor stribesyge og nøgenbrand. Under dyrkningsforhold, hvor de to sygdomme betragtes som nøgle-problemer, burde sortsvalget derfor tager hensyn til de resistensoplysninger, som ORGSEED projektet har tilvejebragt. Men det skal huskes, at muligheden for at bruge sortsresistens ikke kommer af sig selv. Det kræver stadig årvågenhed med hensyn til at følge skift i sorternes sygdomsreaktion over tid og dette kræver fortløbende resistens-screening og –afprøvning af markedsførte sorter såvel som af forædlingsmaterialet. |

| Hydrokultur führt bei Bohnen zu höheren Erträgen, ist aber gleichzeitig qualitätsmindernd. Demeter-Saatgut und konventionelles Saatgut wurden jeweils biologisch-dynamisch und in Hydrokultur angebaut. Die vorliegenden Ergebnisse legen nahe, dass es auch im Pflanzenbau mehr oder weniger artgemäße Anbaubedingungen gibt. Der biodynamische Anbau in Erde erscheint gegenüber der Hydrokultur als weitaus artgemäßer. Nicht artgemäßer Pflanzenanbau von weißen Bohnen in Hydrokultur prägt sich im Samen ab und lässt sich mit der hier angewendeten empfindlichen Lumineszens-Anregungs-Spektroskopie physikalisch messen und statistisch signifikant von eher artgemäßem biologisch-dynamischen Anbau in Erde unterscheiden. Bei den hier untersuchten weißen Bohnensamen wiesen... |

| Baking quality is a major problem of wheat production in organic farming in Germany. The main reason is low protein content, but also different gluten characteristics. The aim of our investigations was to verify, whether selection of varieties with special adaptation to organic farming (or OF systems with particular low input) is advantageous. 66 Genotypes of winter wheat (registered German varieties, breeding lines, older varieties and varieties bred for organic farming) were compared in 5 environments over two years. Yield, protein content and quality parameters were assessed. Aptitude to LI- or HI- conditions was determined using intravarietal linear regression. While selection for special adaptation proved to be superior for yield and protein yield,... |

| In the Netherlands the organic sector keeps growing, but organic potato production is lagging behind. This is due to the relatively high disease pressure from Phytophthora infestans, which causes foliage and tuber late blight. For organic potato growers this disease still forms a major cropping risk. In the potato breeding programme Bioimpuls, the Louis Bolk Institute and Wageningen UR are working together with breeding companies and farmer-breeders to develop robust cultivars that are resistant to Phytophthora. Thanks to these new cultivars, organic growers now have more chance of yield security. The next step is to collaborate with organic wholesalers and retailers to make sure that the new cultivars reach the shop shelves and consumers’ plates. In the... |

| Productivity in agriculture has more than tripled in developed countries since the 1950s. Beyond the success of plant breeding, the increased use of inorganic fertilizers, application of pesticides, and spread of irrigation also contributed to this success. However, impressive yield increases started to decline in the 1980s because of the lack of sustainability. One of the most beneficial ways to increase sustainability is organic agriculture. In such systems the prerequisite of successful farming is the availability of crop genotypes that perform well. However, selection of winter cereals for sub-optimal growing conditions is still neglected, and the organic seed market also lacks of information on credibly tested varieties suitable for organic... |

| Dans le Sud de la France, la culture du fenouil sous abris est essentiellement pratiquée en agriculture biologique ; les maraîchers bio disposent donc de peu de référence sur les techniques culturales (problème d’hétérogénéité à la récolte) et sur le choix des variétés adaptées aux conditions spécifiques de culture sous abris en Provence. De plus, l’utilisation obligatoire de semences biologiques ou à défaut de semences conventionnelles non traitées limite le choix variétal. Cet essai a différents objectifs : - en culture de fin d’hiver sous abris, tester des variétés de fenouil disponibles en semences biologiques ou en semences conventionnelles non traitées. - comparer 2 méthodes de plantation : mottes « salades » posées ou mini-mottes cylindriques... |

| Hochwertiges Saatgut ist ein wichtiger Faktor zur Produktion gesunder Lebensmittel. Im ökologischen Landbau hat der Aufbau einer eigenen Züchtung daher hohe Priorität. Was unterscheidet die ökologische Pflanzenzucht von der konventionellen Züchtung? Sollen insbesondere die gleichen Techniken wie in der konventionellen Züchtung verwendet werden? Beurteilungskriterien, welche Technologien bzw. Methode sich für die biologische Züchtung eignen und welche nicht, sind in Entwicklung doch einheitliche Regelungen stehen aus. Dies führt zu unterschiedlichen Vorgehensweisen bei der Beurteilung dieser Technologien und Unsicherheiten in Forschung und Praxis. In diesem Workshop sollen die folgenden Aspekte diskutiert werden: - Darstellung aktueller Stand von... |
