In order to improve digitization of watermelon germplasm data management, and explore computer-aided breeding technology in hybrid parents screening, we reviewed the development of watermelon breeding both in China and abroad, studied computer-assisted breeding technologies, learned the development of construction of germplasm database in various areas, then we studied the standard of the description of watermelon traits and their genetic patterns, together with all necessary technologies for a WEB system. Finally we developed a WEB system for management of watermelon germplasm data and prediction of hybrid parents combination.The WEB system has two advantages in data management:1. A single database will store all watermelon breeding data throughout the whole breeding period, and provide functions of adding, deleting, editing and querying data, so that the phenomenon of multi-location, multi-material and personnel-change doesn’t bother breeders that much as it used to be, and breeders can concentrate on utilizing their precious data.2. The system has set a data adding mode for all users of this WEB system, so even a novice of breeding can easily add germplasm data as long as he or she operate on this mode. Meanwhile, the functions of multi-user and remote operation can enhance the efficiency of data synchronizing and exchange, as different users can operate the WEB system at the same time or in different places. These two points of innovation will reduce mistakes or incidencts during data entry process compared to the manual operations that people doing now.This WEB system developed a module for prediction of hybrid parents combination. When a user set his breeding objective, the WEB system will calculate reversely and combines parent materials for prediction. And after calculation, system gives out the result according to a logical order of target progeny’s probability in the first place and total sugar content(TSS) in the second place.The prediction output should be considered as a reference for breeders who are looking for candidates of hybrid parents for his target cultivar.In the future, the WEB system will develop better with more support, like to open some interface of the database and expand applicable crop types, or to improve compatibility so that the WEB system can be better promoted among potential users.
