Before a variety is granted Plant Breeders' Rights or is listed on the National list, a technical DUS-test is required. Administrative testing is also carried out.
In the technical DUS test Naktuinbouw establishes if the new variety is clearly distinguishable from all other existing varieties within the specie concerned (Distinct), whether the variety remains uniform during propagation (Uniform) and whether the characteristics of the variety remain stable during repeated propagation (Stable). In field tests and greenhouse tests, Naktuinbouw investigates individual plants of the variety and of the comparison varieties.
Resistance properties are valid as a characteristic of distinctness. Naktuinbouw can perform resistance tests.
Send samples on time and correctly
It is important that a sample of a new variety is submitted in time - before the start of a new season. There is a closing date for each specie.
The sample must meet a number of demands, such as the nature of the material, the size of the sample and the health status. Seed must not have been treated, unless with express prior permission. Seed may never be pelleted or primed, as these treatments can mask the characteristics of the seed and influence the germinating power, and therefore subsequent specie development.
If the identity sample is not submitted in time or fails to meet these demands, the Board for Plant Varieties will automatically withdraw the application.
New characteristic - tell us at once
Naktuinbouw performs tests according to CPVO protocols (Community Plant Variety Office), UPOV-guidelines (International Union for the Protection of New Varieties of Plants) or National protocols.
Does the distinctness of a new variety depend on a characteristic that has not already been included in one of these protocols? Please report this when submitting the application. Normally, being able to work with a new characteristic requires permission in a separate procedure. This is time consuming and can delay the admission process or obtaining Plant Breeders' Rights if it is only made known at a later stage.
During the test
Technical DUS testing usually takes two growing cycles. A growing cycle is the time the test takes to observe all the characteristics which are required for the DUS test. The final report usually follows after the second growing cycle. If there are still any aspects that are not clear, an extra growing cycle may be necessary. At request Naktuinbouw can perform two growing cycles in one year.
After each growing cycle the applicant will receive an interim report stating the current status and the plans for the next growing cycle. Test fees will be charged for each growing cycle.
Naktuinbouw will invite the applicant to come and visit the trial. If Naktuinbouw encounters any problems during the test, the applicant will be informed.
If the variety meets the DUS requirements, Naktuinbouw create a report, including the variety description.
This draft report will be send to the applicant, with the request to agree to go. If necessary, changes can still be made in the report. Then Naktuinbouw offers the report, the decision to the secretary of the board for plant varieties.
