The Organisation for Economic, Co-operation and Development (OECD) Seed Schemes are a set of procedures, methods and techniques which enable the quality of seed to be monitored during the multiplication process and which ensure that the varietals identity and varietal purity of a cultivar is maintained and safeguarded. Any seed lot moving into the International seed trade is required to be produced under these procedures. These methods over a period of many years have been found to give satisfactory results and provide the principles upon which such methods should be based.

These have been adopted by most OECD member and non-member countries. There are six viz., herbage and oilseed, cereal seed, sugar beet and fodder beet seed, vegetable seed, seed of sub terranean clover and similar species and maize and sorghum seed OECD schemes for varietal certification of seed moving into International trade. These schemes are open on a voluntary basis for all members of organization as well as to other states being member countries of the UNO or of its specialized agencies desiring to participate in these schemes. If a country participates in the schemes, it is obliged to ensure that the rules of the schemes are strictly observed. There are two procedures used in OECD Seed Certification Schemes which are designed to check the progress of a cultivar at different stages in the seed multiplication process.

i. Tests on plants grown in control plot and on seeds and seedlings grown in the laboratory using samples of seed drawn from a seed lot.
ii. Field inspection of seed crop to report on their condition.
