Japan’s National Agriculture and Food Research Organization initiated a collaborative research project with France’s National Research Institute for Agriculture, Food and Environment to evaluate wheat genetic resources and to identify materials with desirable traits using standardized criteria. This paper presents the current status of trait data standardization between the two organizations and outlines a direction for standardization. Trait data for genetic resources in Japan and France are managed using independently developed standards. The lack of mapping standards hinders data integration and interoperability. To support experts in the mapping process, we developed a tool that translates trait terms. A generative AI-based translation tool appears to be applicable for collecting relevant information to support mapping between trait terms, as well as translating newly submitted Japanese trait terms into English.
