伝統野菜のタネの地域内保全の現状と課題

―奈良県の大和野菜を事例として―

抄録

This paper examines the present situation of in-situ conservation of traditional vegetable varieties in Nara Prefecture, and how local producers reproduce original seeds of Yuzaki Nebuka (onion) and Katahira Akane (red turnip) to retain geographical authenticity of the products. Local Japan Agricultural Cooperatives (JA) play a vital role in collecting, storing, and allocating the seeds of Yuzaki Nebuka. In the case of Katahira Akane, however, villagers organize a competition for the turnip every year, in which plants of good quality are selected to multiply, as an attempt to conserve good seeds. However, there are few successors of both crops, partly because these brands are too narrowly defined in terms of producing areas. This implies that some flexibility is needed in order to establish geographical legitimacy and implement an effective in-situ conservation of traditional vegetables.
