Quality declared seed (QDS)


Seed classes


“””Seed in a quality control system, introduced by FAO, whereby 10% of the seed fields and lots are checked by an autonomous quality control agency and the remainder by the seed production organisation.””

Note: Various other schemes for quality declaration have emerged in different contexts, such that QDS is often used as a more general term for seed which is not resultant from a formal production system, but in which quality is assured through the reputational identity of the producer group.”
