Prolongation September 2025
This year, prolongation can be applied for vegetable and agricultural varieties that were listed in 2017. This also applies to vegetable varieties that were listed in 2004 and 2005.
The invitation will be sent in September
The Board for plant varieties will sent the invitation in September. From that day on, the prolongation module will be open.
Please note!
- The deadline for submitting an application for prolongation is December 31, 2025. On that day, the application fee for prolongation must be paid. Only then, applications can be processed.
- The maintainer of the variety is responsible for the prolongation of their varieties. We therefore ask the maintainer to carefully check which varieties are eligible for prolongation.

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.
