The breeding and development of new wheat varieties has become more important than ever as one of the tools to increase domestic production. In this paper, we presented the problems of wheat breeding, and we have shown that the spillover has been affected by the climate difference. We presented suggestions for the efficient allocation of the research resources among institutes. We found that the spillover effects are not uniform throughout the institutes and MAKISEI is the key factor to explain that difference. Furthermore, it was shown that institutes other than Hokkaido and Higashiyama could share the same gene resources. This fact indicates that the integration of the research result among these institutes could realeze the more efficient allocation of resources. Also, this explains why Hokkaido and Higashiyama have been the designated institutes.
