Abstract
Seeds are one of the most important foundations for the stable supply of food and expansion of export of agricultural products. In this study, I investigated the breeding of new seed varieties (breeding of agricultural products) by using a questionnaire and factor analysis to clarify the appropriability factors of Japanese private sector. For the analysis, I divided vegetables and flowers on the basis of breeding characteristics. The results of the factor analysis showed that, in both vegetables and flowers, maintenance of breeding resources (genetic and human resources) was suggested as the appropriability factor. Moreover, especially in case of vegetables, protection of rights other than those of intellectual property and development and acquisition of technology for F1 plants were suggested as appropriability factors. In addition, in case of flowers, new breeding methods (e.g., gene modification technology) were suggested as a factor. The results of this study show that, in order to improve the R&D incentives of the private sector, it is necessary not only the viewpoint of a breeder's right but also the other system for appropriability. In addition, it is necessary to consider the acquisition of advanced technology as a function of appropriability.
