| This is the final report of Defra project OF0166. There is a longer summary at the start of the attached main report. For many farmers and growers, a move to organic production presents major challenges. Among these, the issues regarding the use of organic seeds could yet be a stumbling block, as growers and the seed trade have reservations about using and producing them for four major reasons: 1) The availability of a wide range of organic varieties appropriate to all year round crop scheduling, and differing production techniques and markets 2) The impact of derogation on managing the supply and demand for organic seed 3) The technical issues of organic seed production 4) Maintaining high standards of seed quality, hygiene and vigour. Three... |

| This is the final report of MAFF/Defra project OF0157. Genetically modified (GM) crops cannot be released into the environment and used as food, feed, medicines or industrial processing before they have passed through a rigorous and internationally recognised regulatory process designed to protect human and animal health, and the environment. The UK body that oversees standards in organic farming, the United Kingdom Register of Organic Food Standards (UKROFS), has ruled that genetically modified (GM) crops have no role to play in organic farming systems. They, therefore, have concerns about the possibility and consequences of the mixing of GM crops with organic crops. The two main sources of mixing are through pollen and seed. Pollen from GM... |

| Fifty spring barley varieties grown under organic as well as conventional growing conditions in experimental fields in four combinations of year and site were studied. The yield varied much within and between environments (years and sites) and systems. Further, the variation between varieties was substantially and it differed between different environments and systems. Associations between observed grain yield of these varieties and disease and growth characteristics assessed in the official conventional variety testing were compared between the organic and the conventional system. Using factorial regression analysis, the best model for predicting the observed grain yield each year from these characteristics the previous year was found. In this model, the... |

| This report presents an analysis of the national reports according EC Regulation 1452/2003 of the years 2004 and 2005, recording the number of authorisations permitted, the quantity of nonorganic seeds used and the main reasons for allowing derogation for each crop (species). The work was carried out as part of the “EEC 2092/91 (Organic) Revision” project (No. SSPE-CT-2004-502397) within the EU 6th Framework Programme. The main objective was to analyse national derogation reports with respect to total seed use of selected species/subspecies, and to analyse the feedback from expert interviews and meetings regarding the implementation of the new seed regulation, in order to provide recommendations for further improvement of the implementation of the... |

| The key questions which will be addressed in this report are: • Which variety characteristics are important for organic farming and are they different from conventional farmers demand? • What is an “appropriate“ variety for organic farming? • Is the actual variety offer available to organic farmers satisfactory? Is it different per crops type and/or per geographic area? • How should variety trials be conducted in order to supply the information needed by organic operators? The main answers may be synthesized as follows: Characteristics of varieties to be used in organic farming are partly different from the ones requested in conventional farming. Main differences are related to yield stability, processing properties and root-system development; The... |
