Mit dem Durchführungsbeschluss 2014/150/EU fordert die Europäische Kommission die Organisation eines zeitlich befristeten Experiments, welches Ausnahmen in Bezug auf das Inverkehrbringen von heterogenem Pflanzenmaterial zulässt. Das als Populationen bezeichnete heterogene Material muss die DUS-Kriterien der regulären Sortenzulassung nicht erfüllen. Stattdessen wird im Durchführungsbeschluss ein Mindestmaß für die Heterogenität der Populationen vorgeschrieben. In diesem Beitrag stellen wir Ergebnisse von Wertprüfungen der in Deutschland zugelassenen Winterweizen-Populationen vor, die 2016/17 und 2017/18 gemäß den Richtlinien für landwirtschaftliche Wertprüfungen und Sortenversuche des Bundessortenamts durchgeführt wurden. Erfasst wurden der Ertrag,... |

On several locations in Germany and Switzerland, new and local varieties of winter wheat were compared to the variety "Bussard" in trial plots with 2-4 replications. Among other parameters, baking quality and gluten content were analised and discussed. |

Despite quite intensive testing of varieties, predictions of future performance of varieties, when grown on specific locations, are known to be nearly impossible; this especially within organic growing systems, where no pesticides and fertilizers can help stabilize yield. Therefore, using mixtures of appropriate varieties might be a way to obtain more stable and acceptable yields. Variety mixtures have so far been studied mostly under conventional farming conditions and focus has often been to characterize disease progress of one pathogen. Here we consider simultaneously four important foliar diseases on spring barley grown in organic as well as conventional growing systems. Further, we study the changes in disease severity of variety mixtures when... |

To face and better manage the development of new varieties in a society calling for more and more transparency, the French National Research Institute (INRA) has get involved in an ambitious reflexive program about the question of "impacts, acceptability and management of varietal innovations" engaging all its thematic research departments. New collaboration between social and technical sciences are promoted to produce, from exemplary case studies, generic concepts and tools to assess the different types of impact of a new variety. Breeding and management of new genetic materials adapted to organic farming conditions constitute an appropriate theme to develop such an integrated process. A pluridisciplinary research team, associating plant breeders, soil... |

Auf modernem Zuchtmaterial basierende, offen-abblühende Maispopulationen könnten vor allem für ökologische und Low-Input Anbausysteme eine alternative zu Hybriden darstellen. Im Rahmen des zeitlich befristeten Experiments 2014/150/EU der EU-Kommission wurden 2016 fünf moderne Maispopulationen vom Bundessortenamt zugelassen. In einem BÖLN-Projekt wurden in 2017 und 2018 Leistungsprüfungen aller zugelassenen Maispopulationen (mit Hybriden als Referenzsorten) unter konventionellen und ökologischen Anbaubedingungen durchgeführt. Wir stellen die Ergebnisse dieser Leistungsprüfungen vor, ziehen Schlussfolgerungen über das agronomische Potential von Maispopulationen und diskutieren zukünftige Perspektiven. |

For organic crop production, well-characterised varieties increase the possibilities for controlling diseases and weeds and compensating for deficits in nutrients. Variation in grain yield was studied in about 150 spring barley varieties and variety mixtures and 20 combinations of location, growing system and year. Choice of variety was found to be as important a factor for grain yield as other factors in the management. Some variety mixtures out yielded even the best variety in the mixture, when this was grown in pure stand. Finally, a concept for organic variety testing of spring barley was developed. This Danish project is part of a European COST Network on sustainable low-input cereal production (SUSVAR) which coordinates studies in different countries... |

La biodiversità è un indicatore della salute dell'ambiente ed è la principale risorsa naturale a subire gli imprevedibili cambiamenti climatici. Molta biodiversità è stata persa: questo aspetto è meglio conoscito come erosione genetica. La riduzione della biodiversità è determinata sia dall'attività umana che dai naturali processi evolutivi. Istituti di ricerca, governi regionali e associazioni non governative lavorano a diversi livelli per preservare molte specie in via d'estinzione. Ci sono molte associazioni di agricoltori custodi (seed savers) nel mondo che stanno ricercando e conservando cultivars locali di piante. Il C.R.A.B. ha identificato sette cultivars locali di mais in Piemonte (Pignoletto giallo, Pignoletto rosso, Ostenga, Nostrano... |

Heterogeneous crop populations such as composite cross populations (CCPs) have recently been gaining attention, both in the scientific community and with practitioners, particularly for use within organic and low-input agricultural systems. Genetically diverse populations are capable of reacting to unpredictable environmental conditions and of adapting to specific environmental conditions such as future farming systems focussed on reducing external inputs and optimising ecosystem services. Despite the growing interest and legislative support, widespread adoption and acceptance of CCPs throughout the value chain has been slow. The aim of the workshop is to allow participants to explore and identify possible internal and external opportunities and threats... |
