Wageningen Seed Centre (WSC) is active in testing for Distinctness, Uniformity and Stability (DUS) for the purpose of plant variety protection and national listing, according to the guidelines of the International Union for Plant Variety Protection (UPOV).
A special UPOV guideline has been developed for each crop. WSC has been commissioned by UPOV to make a number of these guidelines. WSC has also introduced the use of computer image analysis to the identification process. WSC has the experience and expertise to develop guidelines for new crops and to train people to perform DUS testing.
