Naktuinbouw standardly performs the DUS tests in two growing cycles in consecutive years. We can perform two tests in one year for a number of crops at the applicant's request. For certain crops, we make use of an additional test at our colleagues ÚKZÚZ in the Czech Republic or ÚKSÚP in the Slovak Republic.
You can find a list of these crops below. If your crop is not listed, Naktuinbouw may assess the request individually.
If you would like to have two DUS tests in one year, we will charge the (Dutch) testing fees per test at the start of the test. You can find the testing fees on the website of the Board for Plant Varieties.
You can apply for two tests in one year by indicating this on the application form. The application form can be found on the website of the Board for Plant Varieties.
If ÚKZÚZ or ÚKSÚP performs the second test, you must take into account the submission dates in the Czech Republic (CZ) or Slovak Republic (SK) respectively. Naktuinbouw must be able to send the material to them before these submission dates. You can find the submission dates for the Czech Republic (CZ) and Slovak Republic (SK) on the website of the CPVO.
