| 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. |

| As the financial threshold for cost-effective breeding continues to be raised, increasingly more crops are becoming 'too small' for breeding. The long-term consequence is that production of these crops will become increasingly difficult, because the availablevarieties will not be adapted to future changes in the cultivation system (new methods,new diseases, etc). The question is how to develop alternative crop breeding models for small markets.This is not only a problem for the organic sector, but increasingly also for minor crops within the conventional sector. To address this problem, the Louis Bolk Institute (LBI) is developing innovative approaches to funding and organizing crop breeding for small markets. For various arable crops the LBI has initiated... |

| For further optimisation of organic agricultural systems, more focus is required on organically produced seeds and the development of better adapted varieties. Organic plant breeding and seed production need to comply with the concept of naturalness as applied in organic agriculture, which not only includes the nonchemical and agro-ecological approaches, but also the integrity of life approach. As organic environments are less controllable and are more variable, breeding should aim at improved yield stability and product quality by being adapted to organic soil fertility as well as sustainable weed, pest and disease management. Also the ability to produce economicacceptable seed yield avoiding seed-borne diseases should be included. On the short... |

| The project CO-FREE (2012-2016) aimed to develop strategies to replace/reduce copper use in organic, integrated and conventional farming. CO-FREE alternative test products (CTPs) were tested and integrated together with decision support systems, disease-tolerant varieties, and innovative breeding goals (ideotypes) into improved management strategies. CO-FREE focused on apple/apple scab (Venturia inaequalis), grape/downy mildew (Plasmopara viticola), and tomato and potato/late blight (Phytophthora infestans). Starting point of the project were ten CTPs with direct or indirect modes of action including Trichoderma atroviride SC1 and protein extract SCNB, Lysobacter spp., yeast-based derivatives, Cladosporium cladosporioides H39, the oligosaccharidic complex... |

| Organic agriculture requires cultivars that can adapt to organic crop management systems without the use of synthetic pesticides as well as genotypes with improved nutritional value. The aim of this study encompassing 16 experiments was to compare 23 broccoli cultivars for the content of phytochemicals associated with health promotion grown under organic and conventional management in spring and fall plantings in two broccoli growing regions in the US (Oregon and Maine). The phytochemicals quantified included: glucosinolates (glucoraphanin, glucobrassicin, neoglucobrassin), tocopherols (d-, c-, a-tocopherol) and carotenoids (lutein, zeaxanthin, b-carotene). For glucoraphanin (17.5%) and lutein (13%), genotype was the major source of total variation; for... |

| A radical shift in our approach to crop production is needed to ensure food security and to address the problems of soil degradation, loss of biodiversity, polluted and restricted water supplies, coupled with a future of fossil fuel limitations and increasingly variable climatic conditions. An interdisciplinary network of European scientists put forward visions for future crop production embracing the complexity of our socio-ecological system by applying the principle of diversity at all levels from soil micro-organisms to plant varieties and cropping systems. This approach, integrated with careful deployment of our finite global resources and implementation of appropriate sustainable technology, appears to be the only way to ensure the scale of system... |

| Kool is een belangrijk gewas in Nederland. Koolsoorten vragen veel stikstof (ca. 300 kg N/ha)voor een goede groei, dikwijls meer dan binnen de huidige regelgeving in een biologische vruchtwisseling kan worden geleverd. Stikstof verhoogt de opbrengst, maar bij een hoog stikstofaanbod bereikt de opbrengst een plafond. Er is in het verleden veel onderzoek gedaan om de bemesting te optimaliseren. Voor een verdere verduurzaming van de teelt is het de vraag welke rassen robuust genoeg zijn om bij een beperkte hoeveelheid stikstof en wisselende weers- en groeiomstandigheden toch een economisch acceptabele en stabiele opbrengst te geven. En welke planteigenschappen spelen daarbij een cruciale rol? Door middel van literatuuronderzoek, gesprekken met deskundigen en... |

| 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 production requires novel, robust cultivars especially for crops such as apple, grape, tomato and potato which are very disease susceptible and are often protected by copper compounds. The European project CO-FREE aims to develop innovative methods, tools and concepts for the replacement of copper to reduce the use of copper in organic farming systems. One key strategy is the introduction of resistant cultivars. However, previous studies have shown that the introduction of novel cultivars often meets substantial obstacles as retailers’ and/or consumers’ awareness has to be generated in order to open the market. Resistance is an important issue for farmers but not immediately appealing for consumers as they are hardly aware of the fact that current... |

| In general, the characteristics of organic varieties - and by extension of organic plant breeding - differ from that of conventional breeding systems and conventional varieties. Realising an organic plant breeding system and subsequently steering it to meet changing demands is no less than a mammoth task. The many actions to be undertaken can be divided into short-term commercial and scientific activities, and longer or long-term commercial and scientific activities. Action must be taken in the short-term to ensure adequate quantities of organically propagated plants and seed. This is vital in consideration of Regulation 2092/91/EC which states that, as of 1 January 2000, all propagating material used in organic production must be of organic origin.... |

| When it comes to discussions on genetically modified organisms (GMOs) and organic agriculture, biotechnologists often ask: “Why are your rules so strict? Why ban GMOs when they are the only tool to secure the world’s future need for food? They are more efficient, quicker, etc!” When asked these questions I explain the underlying values of organic agriculture. In this article I will discuss the basic values of organic agriculture as laid down in the IFOAM four basic principles, and will relate them to the field of plant breeding. I also discuss the consequences and challenges for the further development of organic plant breeding. |

| To determine if present commercial broccoli cultivars meet the diverse needs of organic management systems, such as adaptation to low N input, mechanical weed management, and no chemical pesticide use, and to propose the selection environments for crop improvement for organic production, we compared horticultural trait performance of 23 broccoli cultivars (G) under two management (M) systems (organic and conventional) in two regions of the United States (Oregon and Maine), including spring and fall trials. In our trials, location and season had the largest effect on broccoli head weight, with Oregon outperforming Maine, and fall trials outperforming spring plantings. M main effects and G × M interactions were often small, but G × M × E (location and... |

| Organic agriculture regulations, in particular European regulation EC 889/2008, prescribe the use of organically produced seed. For many cultivated plants, however, organic seed is often not available. This is mainly because investment in organic plant breeding and seed production has been low in the past. To bridge the gap between organic seed supply and demand, national and European regulations define certain circumstances under which organic producers are permitted to use non-organically produced seed. While the organic sector currently depends on these concessions, they also threaten to impede a further increase in the demand for organic seed, thereby potentially restraining present and future investment in organic seed production and plant breeding.... |

| Seeds form the basis for agricultural production, but most organic growers know little about how their seedstocks have been produced. Within the organic movement the discussion on the compatibility of plant breeding techniques has been accelerated by the public discussion on genetic engineering. This decision-making is important to develop a framework for organic plant breeding and facilitate investment by breeding companies. This dossier explains all standard techniques used in modern plant breeding and why they have been developed. The consequences of not allowing certain techniques for organic plant breeding are outlined, along with suggestions for alternative techniques that could be adopted. |

| Organic production and also the attention for plant breeding for organic agriculture is still increasing in Europe. The question often raised is how much does plant breeding for the organic sector differ from modern plant breeding and does a ban on GMO also include refraining from molecular marker assisted selection (MAS)? In this paper I will first elaborate on the values in organic agriculture and it related systems approach as a central focus in organic agriculture and will then discuss in which way molecular marker assisted selection can be of use for plant breeding for organic and low-input agriculture. |
