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...

Harmonization of Technical Questionnaires (TQs)
The Board for plant varieties has been working with CPVO for some time on the harmonization of Technical Questionnaires (TQs). The objective is to make as many CPVO and the Board for plant varieties TQs as possible identical on a one-to-one basis. This harmonisation will make it easier for applicants to submit either a national application or a CPVO application, as the information can simply be copied from one application to the other. Recently, a number of additional TQs have been harmonized.
