| Inden for ganske få år forventes det, at GM sorter af raps vil blive dyrket i Dannmark. Raps er en af de danske afgrøder, der har det største potentiale for genspredning. Det er derfor nødvendigt at løse de sameksistensproblemer der vil opstå, når GM raps dyrkes i nærheden af økologisk raps og ikke-GM raps. I hvilken grad agerkål og spildraps og urenheder i certificeret rapsfrø bidrager til forekomsten af GM under forskellige forhold, undersøges i et igangværende projekt på Risø og KVL. |

| Landraces, which are unbred cereal species, and include in particular the tetraploid emmer wheat, have become an important focus for the activities of local or organic farmers, processors and consumers of organic products. This study is based on analyses of the spike productivity, harvest index and grain yield of six emmer wheat landraces. It aims to find suitable criteria for the selection of cultivars and varieties which may contribute to the increase in the productivity of the emmer wheat. The cultivars and varieties most commonly used have short dense spikes which have a negative effect on the grain yield, as the spike density is negatively correlated with the weight of thousand grains (TGW), the weight of the grains in the spikes, the number of grains... |

| The trade-value of organically grown wheat is mostly determined by the wet gluten content, the SDS-sedimentation value and the stirring number. Further information about wheat quality can be obtained through the rapid-mix test, however, both the rapid mix-test and laboratory parameters have been criticized for not displaying baking qualities adequately. In this study, 172 samples of organically grown wheat varieties and breeding lines were analyzed for their wet gluten content, SDS-sedimentation value, falling number and their performance in a baking test. A linear regression showed the highest correlation of the bread volume to the SDS-sedimentation value with R2=0,29. A multiple regression model explained 56% of the volume variation by the... |

| Hybrid breeding utilizes the advantages characterizing F1 plants in a targeted manner: Vigour, uniformity, and a combination of all dominant traits of the parental lines. It gives breeders secure licences, as farmers can not save seed from hybrid varieties with a view to replanting. Regarding rye, the current advantages of hybrid varieties are primarily the higher yields but also improved resistances to lodging and sprouting. However, farmers can only benefit from higher yields if the limited market for organic rye in Switzerland can be expanded. The currently available hybrid rye varieties have higher susceptibility to leaf rust and ergot infections. The criticism of hybrid breeding and hybrid varieties concerns four areas: Firstly, the area of... |

Participants from nine states took part in the seminar. With experience in the breeding of new varieties, their evaluation and seed production for organic management system introduced experts from Germany, Denmark, the Netherlands and Italy. Sector specialists gathered... |

| Hulled wheat species (einkorn, emmer, spelt) are presumed to be an alternative to bread wheat in organic agriculture since the yield penalty is less pronounced under organic farming and generally higher prices can be achieved for specialty grains. The present study analyzed differences between wheat species with respect to biomass production, harvest index, grain yield and protein content. Spring hulled wheat genetic resources and bread wheat check cultivars were grown in organic field trials in the Czech Republic and Austria between 2010 and 2012. Generally, hulled wheat species were inferior in grain yield and distribution of assimilates to the grain compared to modern bread wheat. Biomass production of some emmer and spelt landraces was similar to bread... |

| Im Projekt zur Evaluierung von Genbanklinien von Lupinus albus L. konnte gezeigt werden, dass Variabilität in der natürlichen genetischen Resistenz gegen den pilzlichen Erreger der Anthraknose (Colletotrichum lupini) vorhanden ist. Acht Prüfstämme (BGRC-3931, LUP 2029, BGRC-3920, LUP 210, LUP B 1097, BGRC-3907, LUP 2042, BGRC-3907, LUP 2042, BGRC-3969) zeigten in zwei Untersuchungsjahren eine deutlich bessere Resistenz als der Durchschnitt. Der Stamm mit der besten Resistenz (BGRC-3931) zeigte im zweijährigen Durchschnitt etwa 25 Prozent der Anfälligkeit der anfälligsten Sorte. |

| Die Fababohne (Vicia faba L.) ist als Körnerleguminose eine ‘low input’-Frucht, die gut zur ökologischen Landwirtschaft passt und die dem ökologischen Anbausystem eine Reihe von Vorteilen gibt (z.B. ‚break crop’, positive N-Bilanz, Unkraut-Unterdrückung). Der Einsatz von Chemikalien in der konventionellen Landwirtschaft mildert dort teilweise die Auswirkungen von Umweltschwankungen auf die Feldfrucht. In der ökologischen Landwirtschaft ist es sehr wichtig, genetische Variation zu nutzen als Mittel, um mit den agro-ökologischen und umweltbedingten Schwankungen umzugehen, um das Risiko eines Anbau-Misserfolges zu vermindern. Deswegen benötigt die ökologische Landwirtschaft Sorten, die besonders an die ökologischen Bedingungen angepasst sind. Die... |

| Village projects introduced to Kars in 2006 aim to revive heirloom seeds and traditional products. The goal is to develop a healthy village model that addresses local's relationship to their environment within a holistic framework. Besides Organic Certification Program, supportive activities developed traditional skills. The project was awarded for the revival of emmer wheat, as IFOAM/Rapunzel One World Award Finalist in 2010. |

| Grass clover leys form the basis of most organic farming systems yet the selection of seed mixtures is often founded on tradition or cost. Based on a review of recent and past research this review provides a wealth of information on grass and legume species and varieties, mixture selection, ley establishment and pasture management. The objective of the Grass Clover Ley research review are: 1. To identify all the relevant research undertaken 2. Collate the results of the research 3. Draw on farm and commercial experience 4. Summarise the practical implications of the research for organic farming 5. Facilitate access to the results of research to advisers in a form which allows easy transfer to farmers. The report presents key conclusions about the... |

| Begrenzender Faktor im Freilandanbau von Tomaten in Privatgärten und Gärtnereien in Deutschland ist die Kraut- und Braunfäule (Phytophthora infestans). Ausgehend von 3500 Akzessionen aus Genbanken, Initiativen, Saatguthandel und von privaten ErhalterInnen wurde die Phytophtora-Toleranz geprüft, um Sortenempfehlungen für ökologischen Anbau und Jungpflanzenverkauf zu erarbeiten. 92 Sorten wurden dreiortig geprüft. Die besten Sorten wurden jährlich an über 25 Orten angebaut. Empfohlen werden die Wildtomaten Rote Murmel und Golden Currant, die Cocktailtomaten Celsior, Resi Gold, Cerise gelb und Cerise rot, die Salattomaten Matina und Rote Zora, die Kochtomate De Berao und die Fleischtomate Paprikaförmige. Von besonderer Bedeutung war die Frage, ob die Auslese... |

| La sauvegarde de la diversité biologique des plantes cultivées est nécessaire pour - conserver ce patrimoine génétique - rendre disponible les ressources génétiques - disposer d'un réservoir permettant d'affronter des problèmes qui pourraient surgir dans le futur. La compétence nationale pour la conservation des ressources phytogénétiques est assurée par la RAC.Les secrétariats de la Commission suisse pour la conservation des plantes sauvages (CPS) et de la Commission suisse pour la conservation des plantes cultivées (CPC) sont localisés à la RAC. Ces deux Commissions assurent la coordination des travaux de conservation au niveau suisse, respectivement des plantes sauvages et cultivées. A travers ces Commissions, des contacts étroits sont entretenus... |

| Laut EU-Öko-Verordnung ist es nicht zulässig, konventionell vermehrtes Saatgut im Ökologischen Landbau einzusetzen, solange biologisch vermehrtes Saatgut einer Sorte zur Verfügung steht. Das Problem im Gemüseanbau liegt jedoch in der Verfügbarkeit eines ausreichenden Sortiments an Gemüsesorten. Beim ökologisch produzierten Gemüsesaatgutangebot besteht dementsprechend eine Lücke. Bei steigendem Öko-Anteil am gesamten Gemüseabsatz im LEH ist hier Handlungsbedarf geboten. Mittels des Projekts soll bei unmittelbar geeigneten Sorten eine Erhaltungszucht unter Berücksichtigung der sortenrelevanten Eigenschaften als Grundlage eines Nachbaus unter ökologischen Bedingungen erfolgen, sodass hier direkt eine Erweiterung des Öko-Sortiments realisiert werden kann.... |
