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.
