17 Economic Analysis about the Revision of the Plant Variety Protection and Seed Act in 1998 About the Farmer's Personal Proliferation of Seed and Seedling Takashi Nozu Assistant Director Agricultural Production Support Planning Division, Agricultural Production Bureau Ministry of Agriculture, Forestry and Fisheries Abstract The effects of breeder's right have come to reach the farmer's private proliferation of some kinds of plant after the revision of the Plant Variety Protection and Seed Act in This thesis shows by the measurement analysis using the panel data that the registration of the breeder's right of these plants by foreign companies has increased by the law revision although the registration by Japanese companies has not changed. Keywords: Plant Variety Protection and Seed Act, Breeder s Right, Farmer's Personal Proliferation of Seed and Seedling
