Abstract: As one of the fastest growing high-tech fields in current world,agricultural biotechnology has gradually rewritten the history of species evolution in centuries. The research of its development trend is of great significance to the government and relevant researchers. On the basis of Incopat patent database,this paper analyzes application years,national patent layout,main R&D organizations,main techniques and high value patents with the aid of DDA,EXCEL and other tools,and summarizes the current situation and the development trend of agricultural biotechnology. The results show that：（1）The development trend of agricultural biotechnology in China is not in the same rhythm as that of international agricultural biotechnology. Particularly,the research ardour of international agricultural biotechnology is declining,while that in China is gradually heating up. （2）Though international corporations are still in a dominant position,Chinese institutions are breaking this situation. （3）Chinese agricultural biotechnology is developing rapidly;however,the quality needs to be improved.（4）In the field of GM technology,applying patent in gene sequences and improving genotypes methods is more active than that in other sub-technologies. Producing new varieties and improving safety by utilizing transgenic plants is blank in the patent protection.
