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. |

Cocoa (Theobroma cacao L.) trees have a lifespan of up to 100 years in their natural environment, the lower strata of tropical alluvial forests. Sustainability of global cocoa production is at stake due to the deterioration of soil fertility, high losses due to pests and diseases (P&D) and old tree stock. Producing cocoa in shaded, low input agroforestry systems offers a potential solution for achieving long-term productivity and sustainability. However, shade-tolerant cocoa clones are needed which are productive and resistant to P&D, as well as meeting the quality standards requested by the industry. In Bolivia, the cocoa mirid (Monalonion dissimulatum) and the novel disease Frosty Pod Rot (“Monilia” Moniliophthora roreri) are among the most... |

This project was designed as an iterative process of describing quality profiles of “organic” and “high-quality” wheat and finding adequate, sensory-based methods to do so. Wheat growing in 1998-2000 at the DOK long-term field trial (FLIEßBACH et al. 2007, MÄDER et al. 2002) was repeatedly investigated. The ripening phase started earlier and lasted longer in treatment D2 (bio-dynamic) and was shortest in treatment K2 (conventional). Coded grain samples were examined in respect to treatment differ-ences in smell and taste. For D2 samples the author used the highest number of “sweetness” terms and the lowest number of other terms, whereas in M (conven-tional/mineral fertilizer only) grains, the highest numbers of “poorness” terms and the lowest of... |

Biologisch gezüchtete Sorten und biologisch vermehrtes Saatgut sind für die Zukunft des biologischen Landbaus von zentraler Bedeutung. Für diese Zukunft leisten die biologisch-dynamischen Getreide- und Gemüsezüchter als bisher einzige in der „Bio-Szene“ wertvolle Pionierarbeit. Eine immer wiederkehrende Frage für diese Züchter ist, ob eine generelle Charakterisierung von Hybridsorten im Vergleich zu samenfesten Sorten möglich ist und ob ihre Qualität durch die Züchtungsschritte beeinträchtigt ist, was von biologisch-dynamischen Forschern immer wieder vertreten wird. Diese Frage ist für die Züchter essentiell, hat sie doch entscheidende Bedeutung für die Ausrichtung ihrer Zuchtprogramme. Folgende Gründe für eine möglicherweise schlechtere Qualität von... |

Zusammenfassung Der vorliegende Bericht möchte am Beispiel des Roggens Informationen und Argumente für die Diskussion bereitstellen, ob Hybridsorten mit den Prinzipien des biologischen Landbaus vereinbar sind oder nicht. Während sich bei Mais und Gemüse Hybridsorten im biologischen Landbau schon ohne eine grundsätzliche Entscheidungsfindung eingebürgert haben, ist in der Schweiz beim Getreide eine grundsätzliche Meinungsbildung und Entscheidung noch möglich. Dies betrifft aktuell vor allem den Roggen. Hybridsorten entstehen aus einer gelenkten Kreuzung zweier verschiedener reinerbiger Zuchtlinien, deren gemeinsame Nachkommen die Eltern im Ertrag übertreffen. Sie sind im Nachbau nicht genetisch stabil, das Saatgut muss daher jedes Jahr neu zugekauft... |

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... |

Introduction In Switzerland, the organic sector has been trying to reduce the massive import of protein crops for feed by encouraging grain legume cultivation during the past years (Clerc et al, 2015). The main limiting factors of low yield stability and high weed pressure were successfully overcome through intercropping of peas and faba beans with barley and oats, respectively. Thus, the production of peas and faba beans grew continuously from 2010 to 2015 from 200t and 90t to 1170t and 560t, respectively (bioaktuell 2017). For more diversification of domestic grain legume cultivation and supply, FiBL has started field trials with blue (Lupinus angustifolius) and white lupins (L. albus) in 2014. The high risk of anthracnose, caused by the fungal agent... |
