Submit a maintenance sample for maintaining vegetable varieties
Naktuinbouw performs the inspection of the maintenance of vegetable varieties.
A variety is correctly maintained if it is true to type. True to type means that the variety is still the same as described in the DUS variety description that was made when the variety was listed in the Netherlands. To perform the inspection of the maintenance, Naktuinbouw requires a maintenance sample in the first year after listing (i.e. registration in the NRR). Subsequently, a sample is requested once in every 5 years. Exceptions are the allium and corn crops. These are inspected once in every 4 years. The maintenance samples will be in a field trial and compared to the original variety description. Read more...
