The basis for the internal list can be found in the Keuringsreglement NL, article 14. It follows from this article that all propagation material intended for export must comply with all EU requirements. Companies may deviate from this, provided that the material complies with the requirements of the third country and that it has been reported to Naktuinbouw.
With the internal list, Naktuinbouw implements the reporting obligation. In addition, inclusion in the internal list ensures that the name of the variety is known to Naktuinbouw, thus preventing another company from trying to get this variety or another variety under that name on the EU common catalogue. In those cases we can alert companies to this.
