| The heavy outbreaks of Phytophthora in 2007, and again in 2012, reconfirmed the need for resistant potato varieties for the organic sector. Until recently no such varieties were available. In 2009 the Bioimpulsprogramme was launched to give more priority to breeding organic, Phytophthora-resistant varieties. In this 10-year programme, wild potato species are crossed with cultivated potato to develop new resistant varieties. Although this classical breeding strategy is a long road, the advantage is that you can select for multiple traits along the way. This brochure presents the results of the first four years of the programme. |

| Skal økologer dyrke hestebønner? Det er der delte meninger om, særligt blandt de avlere der har forsøgt sig med afgrøden. Risikoen ved dyrkning er større end ved korn, men hvis håndværket er i orden kan en række af udfordringerne afhjælpes. Tørke, lus og chokoladeplet er desværre ikke noget økologer er herre over, og derfor er hestebønner en afgrøde der i værste fald mislykkes helt, men i de bedste år giver hestebønner mellem 4-5 tons pr. ha. Usikkerheden i udbytte opvejes i nogen grad af de fordele, som dyrkning af hestebønner giver i sædskiftet. |

| Stagonospora nodorum glume blotch (SNG), caused by the necrotrophic fungus Stagonospora nodorum, is one of the economically important diseases of bread wheat (Triticum aestivum L.). Resistance to SNG is known to be quantitative and previous studies of a recombinant inbred line (RIL) population identified a major quantitative trait locus (QTL) for resistance to SNG on the short arm of chromosome 3B. To localize this QTL (QSng.sfr-3BS) with high resolution, we constructed a genetic map for the QTL target region using information from sequenced flow-sorted chromosomes 3B of the two parental cultivars ‘Arina’ and ‘Forno’, the physical map of chromosome 3B of cultivar ‘Chinese Spring’ and BAC-clone sequences. The mapping population of near-isogenic lines (NIL)... |

| Vårhvede og vårbyg er hver for sig velkendte arter i det økologiske sædskifte, hvor vårhvede normalt dyrkes til konsum og vårbyg i stor udstrækning til foder. I sortsafprøvningerne lykkes det ofte, at opnå udbytter på over 50 hkg/ha, hvorimod udbyttet ude på bedrifterne ligger noget lavere. Særligt vårhvede ligger i praksis langt under 50 hkg/ha. I praksis er det derfor kun en mindre del af sorternes fulde udbyttepotentiale der udnyttes, hvorfor det er interessant at undersøge hvilke praktiske tiltag der kan hæve udbytterne. |

| Most of the currently grown commercial fruit cultivars remain unsuitable to low-input or sustainable organic farming systems. The major reason is that they have been developed and selected under high input cultivation, and without sufficient attention to susceptibility to pests and diseases. Some of these cultivars are nevertheless marketed as resistant because they carry genetic markers for major resistance genes but these are unfortunately prone to break-down (most of apple resistant cultivars relay only on the Vf). As a result, new fruit cultivars tend to reveal unexpected and often undesirable traits when grown in commercial organic orchards, and thus fail to bring about the much needed expansion in organic production and market availability. However,... |

| Candidatus Orchards of 30 to >100 years old fruit trees used for cider production are endangered by an accumulation of abiotic and biotic stress factors. Among biotic stress factors, diseases such as pear decline (PD) caused by the bacterial pathogen ' Phytoplasma ' contributes to a weakening and reduced life time of affected trees. Since direct treatment of this disease is not possible, approaches have gained attention, which might lead to an increased resilience against this pathogen, such as incisions of the cambium at the graft union at the stem base. Six 35 years old pear trees () of a Swiss cider production orchard, all affected by mild decline were chosen for this study. Four out of them were treated with 2-4 incisions per tree in February 2016.... |

| Improved biodiversity is one of the key principles in organic farming and therefore organic plant breeding seeks alternatives to the currently dominant pureline monocultures. Evolutionary plant breeding of composite cross populations (CCPs) has been proposed as a breeding tool for organic plant breeding, where a highly heterogeneous population of offspring is made by mixing a large number of segregating lines from different parents (Döring et al. 2011). Natural selection will, to some extent, reduce traits onferring major disadvantages in a population if these have a high heritability and a significant impact on seed reproduction. It will not, however, necessarily improve baking quality, negative traits with a strong interaction with the environment or... |

| Pea (Pisum sativum L.) is a valuable protein source for food and feed. Pea is able to significantly improve soil fertility and, hence, represents an ecologically important crop in low-input farming systems. Despite their importance, pea cultivation remains below expectations due to low and unstable yields caused by a complex of soil-borne pathogens. The goal of this project is to improve our understanding of resistance mechanisms of pea against soil-borne diseases. To achieve this goal, more than 300 pea lines were evaluated for resistance in pot-experiments and a subset of susceptible and resistant pea genotypes has been identified. In a next step, key pathogens and beneficials in the pea rhizosphere and the role of root exudates in determining the... |
