How to draw a good variety description of your agricultural crop? And how do you fill out the Technical Questionnaire as accurately as possible?

Variety testing (DUS) and describing varieties is based on UPOV-guidelines/CPVO-protocols. Naktuinbouw has developed calibration books for the major crops for listing and/or Plant Breeders’ Rights. The calibration book serves as a practical manual that gives an illustrated explanation of each crop characteristic mentioned in these guidelines/protocols.
