Seed certification

A seed certification service is provided by Seed Services Australia to seed growers and companies, which is of benefit to seed growers, companies, processors, resellers, importers/exporters, research institutes, universities and the wider farming community.

Seed certification is an evidence and field inspection based process that aims to ensure that the genetic identity and purity of a variety is maintained from one generation to the next.

Who can grow certified seed
