American Plant Breeders' Rights, technical examination

To apply for American Plant Breeders' Rights (Certificates of Protection), the applicant must submit a technical examination report to the Plant Variety Protection Office (PVPO) in the USA.

About the variety test

The technical report includes the following:

  • breeding history
  • statement of distinctness
  • an objective variety description
  • additional descriptive information
  • statement of the declaration of ownership
  • With tuber propagated varieties- verification that a cell culture is available

Naktuinbouw can perform the technical examination: draw up an objective description of the variety and indicate its distinctness compared to the best comparable variety/varieties. 


The PVPO has a list for most crops of the characteristics that must be described. These are often different characteristics than those in the UPOV guidelines. Naktuinbouw cannot make the actual application.


The costs can be found in the list of fees. The amounts stated apply per growing cycle.
