Abstract: Investigation on Crop Germplasm Resources and Their Sharing Utilization in Fujian Huang Aiping, Zhang Mei, Lin Haiqing, Ke Wenhui (Institute of Agricultural Economics and Scientific Information, Fujian Academy of Agricultural Sciences, Fuzhou 350003) Abstract: [Objective] This paper aims to study the research and utilization status of crop germplasm in Fujian. [Method]The crop germplasm resources and their sharing utilization in 9 provincial and 7 prefectural (city-level) scientific research units (extension centers) of Fujian Province were analyzed by questionnaire investigation. [Result]The results showed that the quality of research personnel was generally high, 64.78% of which worked on germplasm resources. The most attention of researchers were paid on quality of germplasm and yield traits. The main ways for researchers to get germplasm resources were inter-unit germplasm exchange and self-collection through literature information; 75.03% of researchers thought that the main factors restricted the development of crop germplasm study were insufficient fund, poor experimental conditions and lack of collaboration mechanisms. Two countermeasures for optimizing the sharing utilization of crop germplasm resources were considered to be: enhancing the scientific research cooperation and exchange, and improving the sharing level. [Conclusion]The current crop germplasm resources sharing service didn’t match with the research needs. Therefore, based on the local germplasm resources in Fujian, it was suggested to collect and integrate Fujian crop germplasm resources data, and construct Fujian germplasm resources information sharing and managing platform in order to realize the sharing of crop germplasm resources, and improve the resource utilization efficiency.
