We developed an electronic field notes system with FileMaker for the purpose of improving the efficiency of wheat breeding. The system involves data aggregation and labor-saving digital devices that have been developed in recent years. We verified the efficiency of data acquisition using this system. We found that the efficiency of data collection in the field was improved and human error was reduced; thus, with this system, it is possible to process a large amount of data accurately. Although the field personnel were unfamiliar with the digital devices, they were able to effectively utilize the various programs developed in this study. The
results of this study contribute to improved accuracy in data collection and thus more efficient crop breeding.
