Quality declared seed system FAO Plant Production and Protection paper Series, Vol. 185

The quality declared seed system, as presented in the 1993 FAO Plant Production and Production Paper No. 117, has been widely used and consulted. It has proved to be particularly useful for those working in the field of emergency seed supply and as a source of practical information on seed standards for a range of crop species. The system provided an alternative for seed quality assurance, which was less demanding than full seed quality control systems. However, changing circumstances and needs in the seed sector have prompted a critical review of both the purpose and the content of this publication. This revised version, prepared by an expert consultation, offers a more explicit recognition of the role of national policies and the impact of some recent international obligations on seed provision and a clearer explanation on how quality declared seeds can accommodate local varieties. The list of crops now includes 92 species, of which 21 include open pollinated and hybrids and one includes also a synthetic variety. In making this update, FAO sought to improve seed supplies to farmers and thus to contribute to food security.
