Abstract:

Crop germplasm resources are the strategic resources of our country and the fundamental material for safeguarding national food security and developing modern seed industry.The past 70 years have witnessed China have formed a systematic work of crop germplasm resources,including investigation and collection, evaluation and identification, cataloging and storage, and sharing and utilization. With the rapid development of computer technology, using information technology to promote the standardization of crop germplasm resources’ work is the prospective trend of germplasm resources work. The past 30 years have witnessed China has established a complete database of germplasm resources and information systems for germplasm resources’ work.For the difficulty in traceability of germplasm data, transmission, and property rights disputes in the current germplasm resources, this paper proposes a blockchain-based solution and studies the germplasm resources data Management plan, storage plan, consensus plan and encryption plan based on blockchain . Combined with the current development of germplasm resources’ work and blockchain technology, this paper analysis the prospects of blockchain technology using in the field of germplasm resources.
