Jiangsu Crop Germplasm Gene Bank of China established in 2008 is hosting ca. 55，000 accessions from 54 crop species such as rice， wheat and corn. Considering the huge number of preserved accessions and diverse germplasm types， traditional management methods to independently record various workflow information and germplasm resource data would result in data/information redundancy and unfavorable handling for overall resource investigation and shared service. To meet the requirements of the germplasm bank， we deployed Java Web， distributed database， workflow， visualization and other technologies to design a full-process crop germplasm resource information management system. This system integrates the collection information， preservation and monitoring， reproduction and updating， identification and evaluation， and shared services. By standardizing and defining the data fields of germplasm resources， the management of germplasm resources information is standardized. By clarifying workflows and associated roles， standardized and traceable full-life-cycle management of germplasm resources is realized. Through data visualization technology， statistical analysis and data mining of germplasm resources data can be achieved. The system can greatly improve the working efficiency of germplasm resource bank management ensuring the safe preservation and effective sharing of germplasm resources.
