Calibration books agriculture

How to draw a good variety description? How to fill out the Technical Questionnaire as accurately as possible?

Procedure

Variety testing (DUS) and describing varieties is based on UPOV-guidelines/CPVO-protocols.

For the major crops for listing and/or Plant Breeders’ Rights, Naktuinbouw has developed calibration books. The calibration book serves as a very practical manual that gives an illustrated explanation of each crop characteristic mentioned in these guidelines/protocols.

Crops

For Agricultural crops only the calibration book for potato is available. You can find it on the Dutch part of our website.
