Abstract
We developed a database system to store and analyze crop data which are obtained in breeding tests of various plants. In operating breeding tests, researchers pay considerable labor not only for cultivating but also analyzing obtained data. To improve it, we performed a data-modeling of crop data through investigating a number of reports and also through having interviews with several researchers of breeding. By managing crop data with this model, our system enables researchers to analyze the crop data efficiently, which results in reducing analysis labor of researchers. Our system is designed in consideration of usability: researchers can easily store crop data with their own spreadsheet files. They can also analyze the stored data through web browsers with simple operations such as selecting conditions and items to compare. Further, they can search data with conditions and the result can be downloaded. We evaluated our system by applying some breeding tests, and then we obtain good evaluation results with the comment that the system is useful and it reduces the labor of analyses.
