| 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... |

| Stinkbrand i hvede (Tilletia tritici) er tilstede i såsæden som frie svampesporer. De enkelte kerner er ikke inficerede ved høst, men efter såning spirer sporerne samtidig med kornet, og de fremspirende planter bliver så inficeret af svampen. Stinkbranden kan derudover også være til stede i såsæden som brandbutter, det vil sige de kornlignende sporefyldte sori, som sygdommen danner i hvedeakset. |

| Common bunt (Tilletia caries) is one of the most devastating plant diseases, and a particular problem for organic seed production. Organic farming aims at controlling pests and diseases with the use of biodiversity and resistance. However most organic wheat fields today are sown with monocultures of pure line varieties, and resistance to common bunt is rarely used, even this disease causes severe problems for seed producers and for farm saved seed, as infected seed lots are discarded because of contamination with bunt spores. To improve the system, organic wheat needs resistance to common bunt that is effective enough to prevent development of the disease over time. For this reason several initiatives are ongoing to improve bunt resistance in organic... |

| At present, around 95% of organic production is based on crop varieties that were bred for the conventional high-input sector, lacking important traits required under organic and low-input production conditions. Populations with a high level of genetic diversity are promising for OA (organic agriculture) conditions due to their adaptation, resilience and performance stability in different environments. Organic farming will benefit from cultivars (populations, varieties) that can cope with multiple stresses such as weeds, diseases, pests, climate change and low nitrogen input from manure. In the COBRA project (Coordinating Organic Plant Breeding Activities for diversity), plant genetic diversity and its potential have been investigated from both an... |

| Arbuscular mycorrhizal fungi (AMF) play an important role in the uptake of nutrients and water from soil. Onions, Allium cepa L., are plants with a shallow root system. As a result, onion plants need a lot of fertiziler for their growth. Furthermore, onion plants are sensitive to drought. The aim of the current research project is to study the beneficial effect of mycorrhizal fungi on the growth and development of Allium species and to determine whether it is possible to improve onions for mycorrhizal responsiveness by means of breeding. Variation among Allium species and segregation observed in a interspecific tri-hybrid population indicate that selection and thus breeding for high responsiveness to AMF is possible. |

| Background In recent years soybean (Glycine max L.) has gained significant attention in Europe due to its ability to produce high quality protein for human and animal consumption. Under the climatic conditions prevalent in Central Europe, low temperature is the major factor limiting soybean growth and symbiotic nitrogen fixation. |

| Plant-associated microbial communities play a crucial role for the expression of various plant traits including disease resistance. Increasing evidence suggests that host genotype influences the composition and function of certain microbial key groups, which, in turn, effects how the plant reacts to environmental stresses. Several studies indicate that modern plant breeding may have selected against plant traits essential for hosting and supporting beneficial microbes. However, they also highlight the presence of an exploitable genetic base for the regulation of the rhizosphere microbiota. We illustrate the concept of breeding for microbial symbioses with pea (Pisum sativum L.). Firstly, genotypic variation for the efficiency of a mycorrhizal symbiosis is... |

| 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... |

| Improving crop nitrogen use efficiency (NUE) is important to reducing the environmental impacts of agriculture, for both perennial and annual crops. This study tested winter wheat breeding lines developed in organic and conventional systems, historic wheat varieties and perennial wheat under organic management. There were significant differences among selection categories and among genotypes. However, standard methods of measuring NUE may not be appropriate when the breeding objectives are to reduce N use. Alternative methods of evaluating breeding materials, including regression analysis of grain protein deviation (GPD) and principal component analysis (PCA) were explored. GPD was not found to discriminate well between genotypes in this study, but PCA... |

| Global change is increasingly affecting agricultural production and threatening food security. Organic and low-input farming systems are less demanding in fossil energy and might thus contribute to moderating global carbon missions. Moreover, under increased uncertainty and variability in environmental conditions, these systems offer solutions for buffering against climatic extremes, disease epidemics, changing nutrient availability, and other stresses that will add to already heterogeneous environmental conditions. 2010 has been designated the Biodiversity Target year by Parties to the Convention on Biological Diversity. Yet, it is clear that biological diversity in agroecosystems, measured as the number and abundance of species as well as genetic... |

| The genotype by environment interaction study of broccoli, amongst others demonstrates that traits of a cultivar are sometimes ranked differently when grown in an organic production system compared to a conventional system. This has strong implications for breeding strategies. The breeders interviewed acknowledged that more attention on abiotic and biotic stress resistance in a broccoli breeding programme is needed which is in accordance with the farmers' varietal requirements. The first findings of the field trials show that cultivar performance is influenced by season and region, and differences in treatment (organic versus conventional management). The field trials showed that there are cultivars with broad adaptation such as "Green Goliath". These... |

| Organic strawberry production suffers from high yield losses caused by numerous fungal and bacterial diseases. Two of the most important diseases are the grey mould disease caused by Botrytis cinerea Pers. (teleomorph Botryotinia fuckeliana), and the bacterial angular leaf spot disease caused by Xanthomonas fragariae (Kennedy & King). Beside cultivation methods and organic plant protection measures, the development of resistant cultivars seems to be the most promising strategy in order to improve the productivity in organic strawberry cultivation. Therefore, we established resistance tests to determine resistant and susceptible strawberry cultivars and breeding selections. In a first run, 40 different cultivars and selections were tested for their... |

| Introduction and methods Crop mixtures of cereals and legumes have received recent attention in the scope of climate change and local protein supply. Cereal-legume mixtures are known to increase yield and yield stability compared with pure crops. Thus dedicated breeding strategies for mixed cropping might become necessary. As a model crop, we compared 32 current European spring pea (Pisum sativum L.) and 8 current spring barley (Hordeum vulgare L.) cultivars for their yield performance in mixed and pure stands, with pea as the focal species. Trials were done as an incomplete factorial design (Fig. 1) at two locations in Switzerland with two replications (Fig. 2). We calculated variance components for the general and specific mixing ability (GMA and... |
