Calibration books and calibration manuals Variety Testing
For Dutch Plant Breeders' Rights and/or listing on the National list and the drafting of variety descriptions, the DUS testing is based on CPVO protocols and/or UPOV guidelines. Variety Testing has developed calibration books for many crops. The calibration manuals were developed in cooperation with Japan.
The calibration book and calibration manual are practical documents that provide illustrated explanations for each plant characteristic.
