Innovation situation analysis based on global patent technology of cucum-ber molecular breeding
In order to study the global patent development trend,research and development hot spots,regional distribution and technical layout in the field of cucumber molecular breeding,and reveal the innovation trend of cucumber molecular breeding,this paper summarizes and analyzes the global development trend of cucumber molecular breeding technology from 1987 to 2022 based on Derwent Innovation Index International Patent Database(DII)with the help of DDA analysis tool.The results show that,the molecular breeding technology of cucumber is developing rapidly.Plant genetic engineering and genetic breeding are the core of each technology layout.China has the largest number of applications,with the US being the second.Monsanto,Syngenta,Bayer,Dow,BASF,etc.have all carried out patent layout in major countries,and China has a relatively large number of patents in this field,with Chinese Academy of Agricultural Sciences,Shanghai Jiaotong University,China Agricultural University and Nanjing Agricultural University among the top 10 institutions in the world.In-depth analysis shows that germplasm identification and innovation,resistance to biological stress,method improvement and technology innovation are the research and development hotspots in the field of molecular breeding technology of cucumber.In conclusion,molecular breeding is the preface technology in the field of cucumber breeding,with a rapid development trend.The innovation of germplasm materials,resistance and technological innovation are the hot spots of research and development.China has the largest number of patent applications and research institutions,making it the most valued technology market in the world.The results of this study provide a reference for the rational deployment of cucumber biological breeding technology and the improvement of intellectual property distribution in China.
