OECD seed schemes are largely focused on ensuring the varietal identity and purity of certified seeds.

The Schemes ensure the varietal identity and purity of the seed through appropriate requirements and controls throughout the cropping, seed processing and labelling operations.

These laws regarding purity of seed and type are covered in the paper Law and the Fifth Commandment (No. 258).

The genetic nature, as well as the purity of the GM seeds and harvested material, was confirmed by qPCR anal- ysis of DNA samples.

Grounds relating to agricultural policy objectives may include the need to protect the diversity of agricultural production and the need to ensure seed and plant propagating material purity.
