An online toolbox for cover crops and living mulches Organic Eprints
Crossland, Mary; Fradgley, Nick; Creissen, Henry; Howlett, Sally; Baresel, Jörg Peter; Finckh, Maria R.; Girling, Robbie.
Cover crops and living mulches form an integral component of conservation agriculture promoting soil health and minimising external inputs. The OSCAR Project (Optimising Subsidiary Crop Applications in Rotation) aims to improve practices of conservation agriculture in farming systems across Europe. The principal output of the project is to develop a toolbox to make technical and scientific information publically available to farmers, researchers, and other stakeholders. The continually evolving toolbox is currently available online at www.covercrops.eu and will consist of three facets (1) An interactive user-fed wiki providing information on subsidiary crops species and machinery use with links to published literature. (2) A searchable database on...

Applications of crop competitive ability in winter oats (Avena sativa L.) Organic Eprints
Fradgley, Nick; Creissen, Henry; Howlett, Sally; Pearce, Helen; Girling, Robbie.
Crop competition is a key component of an integrated approach to weed management. Variation in competitive ability and competitive traits have been identified in many other crop species, however little work has been done on oats. Trials were carried out over four years at one organic site with five husked and three naked oat varieties. Mid-season Leaf Area Index (LAI) and tillering ability were identified as weed suppressive traits using path analysis. Differences in weed tolerance were found among varieties. Trade-offs may exist between competitive traits and yield potential which could be optimised by limiting competitive traits later in the season. Selection of competitive traits with high heritability, whilst minimising yield penalties, could...

Breeding for diversity – political implications and new pathways for the future Organic Eprints
Andersen, Regine; Bocci, Riccardo; Howlett, Sally; Pearce, Bruce; Dunsire, Gaina; Rey, Frederic; Nuijten, E.; Andersen, Rikke Thomle; Pedersen, Tove Mariegaard; Miceli, F.; Slabe, Anamarija.
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...

Selecting winter wheat lines from a composite cross population Organic Eprints
Fradgley, Nick; Wolfe, Martin; Howlett, Sally; Creissen, Henry; Girling, Robbie.
The extremely diverse genetic variation in wheat Composite Cross Populations (CCP) represents a valuable source of breeding material. Such material could be selected as part of a participatory breeding programme with the potential advantage of selecting adaptation targeted for particular environments. For example, selections could be made aimed at producing lines that would thrive under the wide range of management practices conducted as part of organic and low input farming systems. Ears were selected from a CCP mixed stand under organic field conditions in the UK and Hungary. Selected lines were multiplied as single ear rows and 1m2 plots. The best performing five lines from the two selection sites were trialled in Suffolk, UK, in replicated plots...

Vergleich genetisch diverser Brokkoli-Populationssorten mit einer F1-Hybride unter ökologischen Anbaubedingungen Organic Eprints
Howlett, Sally; Winkler, Louisa; Döring, Thomas F.; Pearce, Helen; Negri, Valeria; Torricelli, Renzo; Wolfe, Martin.
Field trials were conducted for three years on an organic farm in England to assess the performance and yield variability of two synthetic sprouting broccoli populations with 4 or 8 parents respectively, along with the original landrace mother plants and a commercial F1 hybrid variety as control (Santée). In terms of total yield, Santée outperformed the other entries, but for some other traits, e.g. heading time and number of sprouts, Santée was comparable with the mean of one or more of the genetically diverse entries. Analysis of yield variability over time showed mixed results. With regard to total yield and total sprout number, variability was higher in the F1 hybrid than in the genetically diverse populations, but for other parameters such as average...

Within-crop genetic diversity increases temporal yield stability in organic winter wheat Organic Eprints
Fradgley, Nick; Howlett, Sally; Wolfe, Martin.
Organic farming aims at developing farming systems that do not need unsustainable inputs such as mineral fertilisers and pesticides to regulate the cropping environment. Such systems need crop varieties that are resilient against multiple and variable biotic and abiotic stresses and that make efficient use of the nutrients and resources that are available. Highly genetically diverse cereal Composite Cross Populations (CCPs) have been proposed as an approach to dealing with these stresses (Döring et al., 2011). Field trials investigated the yield stability of two winter wheat CCPs compared to two respective mixtures of their parental varieties as well as high yielding (c.v. Alchemy) and high quality (c.v. Solstice) elite pure-line control varieties at...
