As the art of plant breeding became a professional and increasingly expensive activity, legal protection was gradually provided in member states of UPOV (International Union for the Protection of Plant Varieties), at present 17 in number. The requirements and scope for protection by Plant Breeders' Rights (PBR) are reviewed and are considered to be favourable for plant breeders, growers and national agricultural productivity. Advantages and disadvantages of PBR and patent protection in connection with biotechnology, the rôle of multinationals as plant breeders and aspects of genetic erosion are discussed.
