The OECD Seed Schemes include rules and regulations applicable to eight groups of species constituting the following eight Schemes:

• Grasses and Legumes
• Crucifers, and other Oil or Fibre Species
• Cereals
• Maize
• Sorghum and Pearl Millet
• Sugar and Fodder Beet
• Subterranean Clover and Similar Species
• Vegetables

These rules and regulations define the technical standards developed by seed certification specialists in participating countries in close co-operation with other international seed-related organisations, such as the FAO, ISF, ISTA and UPOV. Many regional seed organisations also participate in the development of technical standards.

The OECD is known for its evidence-based advice and standards, as well as for being a forum where national experts from different areas can jointly develop common standards and procedures. The  collaboration of national authorities and highly qualified seed experts from the private sector in the standard setting process ensures the wide acceptance of the OECD seed varietal certification system and its value to the global seed and agricultural sectors.

The World Seed Partnership (WSP) is an initiative established by the OECD Seed Schenes,  the International Seed Federation (ISF), the International Seed Testing Assocation (ISTA), , the International Union for the Protection of New Varieties of Plants (UPOV) and the World Farmer's Organisation (WFO) to promote access to new varieties and high-quality seed that support sustainable agri cultural development. The WSP promotes access to new varieties and high quality seed to support sustainable agriculture and food systems.

Each country has nominated a National Designated Authority (NDA) who is responsible for the implementation of the seed schemes.
