For spring-time cultivation, the Descriptive Variety List has been updated for cereals and expanded to include the newly registered rapeseed varieties. Here you will find the variety characteristics of the agricultural crops
Pursuant to Article 17 of Council Directive 2002/55/EC of 13 June 2002, the Common Catalogue of Varieties of Agricultural Plant Species was established on the basis of the national catalogues of the Member States. In accordance with Council Directive 2002/55/EC of 13 June 2002, the Common Catalogue of Varieties of Vegetable Species was established pursuant to Article 17 of Council Directive 2002/55/EC of 13 June 2002 on the marketing of vegetable seed. In accordance with the entry into force of the Agreement on the European Economic Area (EEA Agreement) common catalogues contain the varieties of the EFTA States, provided that they comply with the Agreement. Furthermore, the common catalogues also include Swiss varieties that meet the requirements.
The varieties included in the Common Catalogues of Varieties are not subject to marketing restrictions relating to variety within the entire EEA territory, except in the cases provided for (ex notes, genetically modified varieties, conservation varieties). A national variety authorisation and the registration into a national list of varieties are preconditions for the inclusion of varieties in the Common Catalogues. The Common Catalogue of Varieties of Agricultural Plant Species was first published on 21 July 1975. The Common Catalogue of Varieties of Vegetable Species was first published on 29 June 1972. Amendments are regularly carried out, based on the information provided by the Member States. New complete editions are published periodically.
The Common Catalogues have four columns
Column 1: Variety (The Common Catalogues are divided into species. Within the species, the variety names are listed in alphabetical order. In cases when seeds of one variety are on the market under different names, one conventional name has been chosen in the interest of simplification; under that name all details of that particular variety are provided.)
Column 2: EU country of authorisation (In most cases, a number is listed after the country abbreviation. This number references the body responsible for the maintenance of varieties in the authorisation country. The key to those numbers can be found in the appendix. Should, however, an 'x' be listed instead of such a number, it means that there are more bodies responsible for the maintenance of varieties in the authorisation country.)
Column 3: EFTA authorisation country (Here, the varieties of Iceland, Norway and Switzerland are listed.)
Column 4: Comments (This column contains information on ploidy, monogerm or multigerm seeds, whether it is a hybrid or genetically modified variety, whether there is a ban on the marketing of seeds in a certain Member State; in the case of deleted varieties information is provided on a possibly granted phasing-out period for the certification and marketing of seeds etc.)
Common Catalogues of Varieties on the Internet
Since 2011, a direct query has been possible within the EU's Common Catalogue of Varieties. Queries can be done by variety, variety maintainers as well as by conservation varieties within each species; varietal characteristics and footnotes can be furthermore be accessed. Various query options are demonstrated. The published complete editions and supplements can be found in the EUR-Lex Official Journal. The Official Journal of the European Union (OJ) is the official compendium of EU legislation (L series) and other official documents of the EU institutions, bodies and agencies (C series on Information and Notices as well as its supplements). The documents published in the Official Journal are available in different formats (HTML and PDF) on the website and can be directly accessed through search functions.

Varieties correction values: N tester
Varieties correction values: N tester
N tester reading
The N tester varieties correction values are used for correctly dimensioning N application when using the N tester. They are updated each year for winter wheat, winter barley, winter rye, winter triticale, winter durum wheat and spring wheat.
The electrophoretic dispersion pattern of stock proteins, which is characteristic for each respective variety and independent of environmental factors, forms the basis for this chemotaxonomic variety identification. In the potato, tuber juice proteins are separated. In grains, particular protein fractions are extracted from the single grain. Variety control is of importance for breeders, export, certification, contract verification as well as for consumers and is required in potato quality class regulation.
The standard pattern of the strain from AGES' Institute for Seed and Propagating Material, Phytosanitary Service and Apiculture serves as reference material. 100 grains are analysed for an electrophoretic characterisation of a newly authorised variety. 100 individual grains are examined in order to determine the purity of a sample; 30 grains are used for varietal identity verification. Soft wheat, durum wheat, spelt, triticale: identification through separation of the gliadins of the single grain DE: Hordenine Barley: identification through separation of hordenines
The standard variety tubers from AGES' Institute for Seed and Propagating Material, Phytosanitary Service and Apiculture serve as reference material. In order to verify the identity and purity of a sample, 6 tubers are analysed from a sample of at least 20 tubers; in the case that there is an unrelated tuber in these 6, then 9 other tubers of this pattern must be investigated for clarifying the degree of mixing. The variety is identified through the direct electrophoretic comparison of sample and standard. Duration of the analysis: 1-2 days
