Prolongation September 2023
This year, varieties registered in 2008, 2009 and 2015 can apply for prolongation. This also applies to all varieties of potato and sugar beet registered before 2015.
Prolongation of registration for an actual Variety Register
The maintainer of a variety is responsible for prolongation.
In September, the Board for Plant Varieties notifies the maintainers of varieties eligible for prolongation. If a variety is not applied for prolongation, the variety will be deleted from the national variety register and the EU Common Catalogue. The marketing of the material is then no longer possible.
A maintainer can have prolongation applied for by an authorised person.
If you receive the invitation for prolongation as breeder/maintainer and you have authorised someone else, or an organisation, please contact the authorised representative.
They can then apply for prolongation on your behalf.
Are you or your organisation authorised representative of varieties eligible for prolongation?
Then contact the breeder/maintainer of the variety so that you can apply for prolongation as authorised representative.

Modification submission requirements French bean (dwarf and climbing beans)
In 2026 Naktuinbouw will start with the implementation of the UPOV Model 2 for DUS testing of bean applications.
It combines molecular thresholds (based on genetic marker distances) with phenotypic observations (based on morphological characteristics).
Model 2 does not replace morphological assessment; rather, it uses molecular data to optimize the DUS process and possibly to shorten it.
Under this model, the initial selection of similar varieties will be based on DNA analysis, followed by a 1st year with field morphological observations to ensure no varieties have been missed. If needed a 2nd year of examination will follow.
Uniformity will be assessed in the field.
