Abstract: An increase in yield has been pursued mainly in wheat breeding research. The initiation of the quality-based trade may lead farmers to choose the variety based not only on the yield level, but also on the quality. Thus, an improvement in the quality, such as an increase in the protein content becomes a major subject in wheat research. It is necessary to allocate the R&D resources efficiently among the several topics. The existing research has focused on the adoption of the technology and the diffusion process of technology. However, there has not been much discussion about the details of the technology development process. Employing the fertilizer reaction function with technology variable "t", we found that the fertilizer has no significant effect on the protein content, while "t", the wheat breeding research, has indicated significant effect. This result implies that the wheat breeding research can take ever more active role in the field of quality improvement of wheat. In order to increase farmer's options, it is necessary to develop high protein content varieties.
