A Collaborative Breeding Strategy for Organic Potatoes in the Netherlands Organic Eprints
Lammerts van Bueren, E.T..
The ability of the organic farmer’s agronomic toolbox to reduce the susceptibility of a potato crop to late blight is limited, certainly under the Dutch climatic conditions. Conventional breeding programs do not generate either a sufficient number nor appropriate types of resistant varieties for organic systems; and a separate breeding program for the limited area of organic potato production is simply not viable. Therefore, all concerned forces have joined together in an umbrella program called Bioimpuls for organic potato improvement.

Agronomic performance of two generations (F12 and F13) of thirteen winter wheat composite cross wheat populations with differing cultivation histories in 2014/15. Organic Eprints
Weedon, Odette; Brumlop, Sarah; Heinrich, Sven; Boening, Andreas; Elsner, Maren; Finckh, Maria R.; Lammerts van Bueren, E.T.; Nuijten, E.; Messmer, Monika; Baresel, Jörg Peter; Goldringer, I.; Péter, Mikó; Megyeri, Maria; Borgen, Anders; Rasmussen, Søren K.; Pearce, Bruce; Wolfe, Martin.
As environmental and agronomic conditions are heterogeneous between and within locations, diversity within varieties or crop populations should increase adaptability to the changing and variable range of growing environments. The additional pressure of plant genetic diversity loss, has driven novel breeding approaches such as Composite Cross Populations (CCPs) and other genotype mixtures, thereby increasing both intra- and inter-varietal diversity and ensuring a “wider adaptation” capacity for crop varieties (Döring et al., 2011). A winter wheat (Triticum aestivum L.) CCP was created by intercrossing 20 varieties in 2001, through collaboration with the Elm Farm Research Centre and the John Innes Institute. In 2005, a seed batch of the F4 was equally...

Breeding for specific bioregions: a genotype by environment study of horticultural and nutritional traits integrating breeder and farmer priorities for organic broccoli cultivar improvement Organic Eprints
Renaud, E.N.C; Lammerts van Bueren, E.T.; Jiggins, J.; Maliepaard, C.; Paulo, J.; Juvik, J.A.; Myers, J.R..
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...

Broccoli cultivar performance under organic and conventional management systems and implications for crop improvement Organic Eprints
Renaud, E.N.C; Lammerts van Bueren, E.T.; Paulo, M.J.; Eeuwijk, F.A.; Juvik, J.A.; Hutton, M.G.; Myers, J. R.
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...

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...

Crop traits relevant for selecting potato genotypes adapted to low nitrogen availability Organic Eprints
Tiemens-Hulscher, Marjolein; Lammerts van Bueren, E.T.; Struik, Paul.
Canopy cover development was measured for 6 to 18 different potato varieties, under 3 different nitrogen regimes. This canopy cover development can be expressed in several paramaters. Of these parameters, the 'Area Under Cover Progress Curve' and the 'percentage of maximal ground cover' show the highest correlation with the final yield in low-nitogen conditions.

Developments in breeding cereals for organic agriculture Inra
Wolfe, M.S.; Baresel, J.P.; Desclaux, D.; Goldringer, I.; Hoad, S.; Kovacs, G.; Loschenberger, F.; Miedaner, T.; Østergard, H.; Lammerts van Bueren, E.T..
The need for increased sustainability of performance in cereal varieties, particularly in organic agriculture (OA), is limited by the lack of varieties adapted to organic conditions. Here, the needs for breeding are reviewed in the context of three major marketing types, global, regional, local, in European OA. Currently, the effort is determined, partly, by the outcomes from trials that compare varieties under OA and CA (conventional agriculture) conditions. The differences are sufficiently large and important to warrant an increase in appropriate breeding. The wide range of environments within OA and between years, underlines the need to try to select for specific adaptation in target environments. The difficulty of doing so can be helped by...

Effect van selectie onder biologische en gangbare omstandigheden bij ui Organic Eprints
Lammerts van Bueren, E.T.; Nuijten, E.H.A.C.P.; Tiemens-Hulscher, Marjolein.
Is er een voordeel te behalen als de selectie van uien voor de biologische teelt ook onder biologische omstandigheden gebeurt, in vergelijking met gangbare selectieomstandigheden? Deze vraag is opgepakt met twee brede basispopulaties (Ronde Rijnsburger Groep en Platte Groep) en het zaadvaste ras Balstora. Er is een trend zichtbaar dat biologische selecties onder biologische omstandigheden een betere opbrengst geven, en gangbare selecties onder gangbare omstandigheden.

Enhancing Resilience Through Plant Breeding Requires an Integrated and Interdisciplinary Approach Organic Eprints
Lammerts van Bueren, E.T..
Breeding in the organic sector is not only a technical activity improving certain desired variety traits but breeding priorities are also determined by the organizational system based on cultural values anchored in specific socio-economic and legal constructions. So, if we want to stimulate breeding for a regionally diverse assortment of varieties of crops that both enhances short-term needed productivity and long-term improved resilience within the frame of the organic principles of health, ecology, fairness and care, we will need to address both the technical and organizational aspects in an integrated and interdisciplinary approach.

Ethics of Plant Breeding: The IFOAM Basic Principles as a Guide for the Evolution of Organic Plant Breeding Organic Eprints
Lammerts van Bueren, E.T..
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.

European perspectives of organic plant breeding and seed production in a genomics era. Organic Eprints
Lammerts van Bueren, E.T.; Wilbois, K-P.; Østergård, H..
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...

Fair seed as a basis for organic products: Eosta takes a stand and supports the breeding of open-pollinated varieties. Organic Eprints
Janmaat, Leen; Nuijten, E.; Lammerts van Bueren, E.T..
Seed is the basis of food crops, and thus for products in shops, and comes with a long history. Plant breeding is developing rapidly, a fact that raises questions among growers, shopkeepers and consumers. In 2015, for the first time European patents were granted to companies for plant varieties and native plant traits, such as for a tomato variety with more healthy substances and a bell pepper variety that is resistant to pest insects. These patents have caused strong social indignation: the free exchange of seeds and plant material with these advantageous qualities is blocked by these patents. As a chain party, at Eosta we are taking a stand against this and support the free breeding in line with the values of organic agriculture as well as our products....

Future breeding for organic and low-input agriculture: integrating values and modern breeding tools for improving robustness Organic Eprints
Lammerts van Bueren, E.T..
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.

Get a taste of new talented Robust potato cultivars Organic Eprints
Lammerts van Bueren, E.T.; Janmaat, Leen; Zeelenberg, Arend.
In the Netherlands the organic sector keeps growing, but organic potato production is lagging behind. This is due to the relatively high disease pressure from Phytophthora infestans, which causes foliage and tuber late blight. For organic potato growers this disease still forms a major cropping risk. In the potato breeding programme Bioimpuls, the Louis Bolk Institute and Wageningen UR are working together with breeding companies and farmer-breeders to develop robust cultivars that are resistant to Phytophthora. Thanks to these new cultivars, organic growers now have more chance of yield security. The next step is to collaborate with organic wholesalers and retailers to make sure that the new cultivars reach the shop shelves and consumers’ plates. In the...

Green Breeding: Bioimpuls Programme 2009-2013 - Perspectives on Phytophthora-resistant potato varieties Organic Eprints
Scholten, Olga E.; Lammerts van Bueren, E.T..
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.

Groene Veredeling: Lupineveredeling voor kalkrijke bodems - Onderzoek naar perspectiefvolle lijnen Organic Eprints
Scholten, Olga E.; Lammerts van Bueren, E.T..
Lupine (Lupinus spp) trekt belangstelling van zowel biologische als gangbare akkerbouwers die zoeken naar een vlinderbloemig gewas om hun vruchtwisseling te verruimen. In 2010 en 2011 zijn eerste verkenningen uitgevoerd met respectievelijk 30 en 57 kalktolerante witte lupinelijnen van de Deense veredelaar Jørnsgård. Sommige lijnen leken geschikt qua kalktolerantie, vroegheid en opbrengst. In 2012 kon het onderzoek onder het programma Groene Veredeling breder worden opgezet en zijn naast de lijnen van Deense herkomst ook lijnen van de Nederlands veredelaar Van Mierlo meegenomen in vier veldproeven, zowel gangbaar als biologisch. Waarnemingen zijn gedaan voor opkomstpercentage, symptomen kalkgevoeligheid, bodembedekking, plantlengte, begin bloei, vroegheid...

Groene Veredeling: Nieuwe rassen voor verduurzaming van gangbare en biologische teelt Organic Eprints
Lammerts van Bueren, E.T.; Scholten, Olga E..
Biologische telers hebben grote behoefte aan meer robuuste rassen. Dat kunnen rassen zijn met een brede weerstand tegen ziekten en plagen, rassen die met minder bemesting toch voldoende opbrengst geven, en rassen die zijn aangepast aan veranderende klimaatomstandigheden. De ontwikkeling van dergelijke robuuste rassen is voor de hele agrarische sector van belang. Robuuste rassen dragen namelijk bij aan verdere verduurzaming van zowel gangbare als biologische teelt. In het onderzoeksprogramma Groene Veredeling dragen Wageningen UR, het Louis Bolk Instituut en andere kennisinstellingen sinds 2010 bij aan de ontwikkeling van deze robuuste rassen. Drie gewassen staan centraal: aardappel, prei, en spinazie. Daarnaast is ook onderzoek gedaan in tomaat, lupine,...
