果樹の個人育種家における登録品種販売の実態と経営上の課題

岡山県のぶどう農家の事例

抄録

The purpose of this study is to clarify the sale of registered varieties and the managerial problems of individual breeders of fruit trees, and for that purpose, we decided to conduct a survey and analysis of an advanced grape farmer who has registered varieties in Okayama prefecture. The specific research tasks of this study are to reveal the sales practices of the individual farmers who breed the varieties, to estimate the development cost of the varieties, and to examine ways to secure alternative sources of income based on the current market size of the registered varieties. As a result of the analysis, it was found that it is difficult to fully recover the cost of breeding varieties through the current sales of seedlings. Therefore, as an alternative measure, we proposed a method of royalty income based on the value of sales in the market.
