| Resistance of tomato fruits to Phytophthora infestans Late blight, caused by Phytophthora infestans (Mont) de Bary, is one of the important diseases in organic potato and tomato production. While some information on foliar disease resistance of tomatoes is available, virtually no information exists on the relation of leaf to fruit resistance. The central parameters of the infection chain, incubation and latency period were determined for 40 tomato varieties using three isolates of P. infestans. A total of 2858 fruits were drop inoculated in the lab and assessed daily for symptoms or sporulation for 16 days. There were significant variety by isolate interactions for incubation period, latency period and the interim time suggesting race specific... |

| Integration of additional leguminous living mulch and cover crop species holds a great potential for reducing external inputs and improving agricultural sustainability. However, changes towards legume rich crop rotations raises concerns as many of the species of interest share important soil-borne pathogens with some important main crops such as peas, beans and cereals. The pathogenicity towards the spring pea variety Santana was determined for 67 isolates of Fusarium oxysporum, F. solani, F. avenaceum, Didymella spp., Phoma medicaginis and Phoma spp. obtained from seemingly healhty roots of Trifolium subterraneum, T. repens, Vicia villosa and V. sativa. Only one isolate of F. solani and two isolates of Phoma spp. were nonpathogenic. F. avenaceum isolates... |

| Climate change scenarios exhibit a definite warming trend (Schröter et al. 2005), and it will have an impact on crop management strategies. Increase in winter precipitation and higher temperatures favour soil borne pathogens and can lead to an increase in survival rate and to more rapid population buildup (Chakraborty et al. 2000). In recent years, one of the main reasons for declining production of summer pea in organic farming in Germany are foot and root rot pathogens (Pflughöft 2008). On the other hand, predicted increase in winter temperatures is expected to favour winter pea over summer pea varieties. The hope is also, that winter peas are less susceptible to root rot as summer peas. However, few data are available. The present study was carried out... |

| Thirteen winter wheat composite cross populations originating from one population but with differing histories over six years and three reference varieties were compared for yield, disease occurrence, as well as phenotypic diversity. The populations performed similarly and often better than the reference varieties in terms of yield and had lower incidence of disease. The populations are also phenotypically diverse and differ among each other, indicating that they have maintained a high degree of diversity over time and in varying locations, but most likely also diverged from each other. |

| Three Composite Cross Populations (CCPs) of winter wheat were created in 2001, one from crossing high baking quality parents (called QCCP), one based on high yielding parents (YCCP), and one created from both parent sets combined (YQ). All three CCPs were grown for several years in the UK and in Germany under conventional and organic cropping management. Based on properties of the different parent sets, yields were predicted to be highest in the YCCP and lowest in the QCCP, with the YQCCP in between. However, data showed that the YCCP was not significantly higher-yielding than the more generalist YQCCP in five out of six sites; in fact, the YQCCP even tended to outyield the YCCP on average over all sites, and this effect was significant at the German... |

| 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. |

| Unpredictable climatic conditions and increasing pressure on non-renewable resources mean that alternative agricultural systems able to cope with increasing biotic and abiotic stresses, as well as external input costs, are needed. Sustainable agricultural systems should be self-regulating, characterized by a high degree of interand intra-specific diversity (Moreau 2010). Evolutionary breeding through the introduction of Composite Cross Populations (CCPs) increases intra-specific diversity, enabling CCPs to adapt to changing environmental conditions. Increasing interspecific diversity, through mixed cropping, also plays an important role in sustainable systems and suitable crops are needed that are able to cope with the increasing interspecific competition... |

| Evolutionary breeding through the introduction of composite cross populations (CCPs)encourages intra-specific diversity and increases diversity in the agricultural landscape. Increased genetic diversity in crops may help to buffer both biotic and abiotic stresses and will play an increasingly important role in unpredictable climatic conditions become more unpredictable (Østergård et al. 2009). A number of CC winter wheat populations, commercial varieties and CCP line selections were tested at the University of Kassel, under differing N input levels in order to test past adaptation and suitability to differing fertilisation levels. The CCPs have been managed since 2005 under both organic and conventional conditions without conscious selection. Genetically... |

| Soil properties at the beginning of the MEE (Multi Environment Experiments) were statistically analyzed in order to verify the field homogeneity. The initial soil properties represent the starting point to interpret the effect of CC and LM on soil fertility during crop cycle.Soil properties of the fields were quite homogeneous at the beginning of crop cycles (first and second). The soil properties of the experimental fields in the selected areas showed a wide variety of pedons to be used for the comparison of CC and LM effect in different climate zones. Soils from the Northern European sites are more acid and richer of nutrients and organic matter with respect to the soils in Southern sites. |

| A lack of appropriate crop varieties specifically bred for the higher biotic and abiotic stresses experienced in organic and low-input systems, has driven novel breeding approaches such as Composite Cross Populations (CCPs) and other genotype mixtures, thereby increasing both intra- and inter-varietal diversity. The creation of CCPs using carefully chosen parental varieties, coupled with the ability of the populations to adapt to local environments means that these populations are well suited for low-input and organic agricultural systems (Phillips and Wolfe, 2005). COBRA (Coordinating Organic plant BReeding Activities for Diversity) aims to “support and develop plant breeding and seed production in Europe by increasing the use of plant material with High... |

| A total of 39 organic faba bean and 59 pea seed lots obtained during 2009-2011 from 32 organic farms throughout Germany were assessed for seed-borne fungi. Seed samples collected from the harvested fields grown from these seed lots were also assessed. The focus in the pathogen identification was on the ascochyta blight complex pathogens Ascochyta pisi, Mycosphaerella pinodes and Phoma medicaginis in pea and A. fabae and P. medicaginis in faba bean and on Fusarium spp. Fusarium spp. were found only rarely on peas with 40 of the seed samples and 44 of the harvested samples free of Fusarium spp. and the maximum infestation rate of 12 % in one harvested sample. Eighteen of the sown and 40 of the harvested lots had infestation rates of > 10 % with the... |

| Krautfäuleresistenz und der Beginn des Knollenansatzes von Kartoffeln sind sehr wichtige Kriterien für die Sortenwahl und somit vorbeugende Maßnahmen gegen P. infestans. Diversifikationsstrategien könnten einen Beitrag zu einer Gesamtstrategie zur Prävention der Kraut- und Knollenfäule leisten und müssen weiter überdacht werden. Zukünftige Forschungsarbeiten sollten größere schmale Felder unter Praxisbedingungen einbeziehen, um einerseits Interferenzen zwischen den Versuchsgliedern zu reduzieren, andererseits die Wirksamkeit unter Praxisbedingungen zu prüfen. Zusätzlich müssen Fragen der Sortenwahl, was Resistenzen betrifft und die Anpassung der Pathogenpopulationen an Sorten mit einbezogen werden. Erste Untersuchungen finden derzeit statt. Pathogenisolate... |

| The six products, Armicarb, Vitisan, lime sulphur, Caso, Calce Fiocco and Ulmasud were tested for their ability to control downy mildew (Plasmopara viticola) on grapevine (Vitis vinifera) in order to find effective alternatives to copper, a heavy metal that is commonly used as a fungicide in organic viticulture. Each product was applied to potted grapevines at i) 40°h (degree hours) and ii) 80°h after inoculation (ai) of the pathogen. These so-called stop-sprays were tested on plants that received two different P. viticola inoculum rates. The formulated potassium bicarbonate product Armicarb and lime sulphur reduced disease incidence and severity similar to or better than the copper hydroxide treatment. Armicarb and lime sulphur reduced disease incidence... |

| Over the past 100 years, the biodiversity within varieties and species of field crops in agriculture has been reduced drastically through plant breeding approaches favouring genetic uniformity for all traits. This has practically eliminated all co-evolutionary proc-esses between hosts and their pests and pathogens. It also does not allow for dy-namic adaptation of plant populations to changing environment e.g. climatic change. Breeders and pathologists have all along pointed out the danger of this approach. Alternative approaches to the pure line breeding have been developed by using com-posite crosses, top crosses and population breeding. These have also been termed “evolutionary breeding”. The need for the reintroduction of diversity within our varieties... |

| Foot rot is an important limiting factor in pea production in Germany (Pflughöft, 2008). The disease is caused by a pathogen complex consisting of Ascochyta complex pathogens (Mycospharella pinodes, Phoma medicaginis and Ascochyta pisi) and Fusarium spp. However, little is known about the specificity of single pathogens of the complex and their impact on plant performance. In order to address this problem pot experiments with five isolates each of Fusarium solani f.sp pisi, Fusarium avenaceum and Mycosphaerella pinodes were carried out in controlled conditions. Three weeks after sowing and inoculation disease symptoms were assessed and plant growth parameters measured. All pathogens caused root discoloration and development of disease symptoms on pea... |
