| Durch ihren hohen Proteingehalt und tiefen Nährstoffbedarf ist die Weisse Lupine (Lupinus albus) eine nachhaltige europäische Alternative zum gegenwärtig massiven Sojaimport für Futter und Nahrung. Der Lupinenanbau ist jedoch durch die Brennfleckenkrankheit Anthraknose, verursacht durch den saatgutbürtigen Pilz Colletotrichum lupini, stark eingeschränkt. Schon ein geringer Saatgutbefall kann zum totalen Ertragsausfall führen. Für einen erfolgreichen Anbau der Weissen Lupine ist es daher wichtig, Resistenzquellen zu finden. |

| 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... |

| In context of a larger project dealing with the traits of barley that are related to organic farming (BAR-OF), we performed an association mapping in order to dertermine the genetic loci linked with the respective traits. In two subsequent years (2002 and 2003), we used field results from 96 barley lines and varieties, partially overlapping between the years. The lines/varieties were grown on three Dansih locations (Flakkebjerg, Foulum and Jyndevad). For Foulum and Flakkebjerg, we observed both fields grown under organic and conventional regime; for Jyndevad only fields cultivated under organic conditions were ecploited. Neither in the organic nor in the conventional fields; diseases were controlled chemically. In the resulting five environments per year,... |

| 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,... |

| Increasing yield instability due to climate change could be mitigated by higher interand intra crop diversity. During the course of the INSUSFAR project, several questions regarding the impact of more diverse crops on agricultural systems are adressed. To answer these questions, varieties, mixtures, and composite cross populations of wheat will be investigated in field experiments and on-farm. Based on the results, the socio-economic, ecological and yield performance of these varieties and the extent of genetic changes in genetically diverse populations will be tested. In addition, effects of plant breeding on the adaption of varieties to different input levels will be analysed. |
