European Catalogue

A vegetable or agricultural variety is included in the EU Common Catalogue if it is accepted in at least 1 national list of 1 of the member states of the European Union. The variety can then be traded within the whole EU.

Publication in the Plant Variety database

Once a variety is admitted to the national list of the Netherlands, the Board for plant varieties notifies these varieties to the European Union and the EU member states. The variety is then published in the Plant Variety Database (Common Catalogue) of the EU.
