基于专利的玉米生物育种技术景观分析

Technological Landscape Analysis of Corp Biology Breeding Based on Patents

面对我国供求形势日趋严峻的粮食问题,加快生物育种技术研究成为解决问题的首选。基于德温特数据库,采用技术景观分析法,从专利权人合作景观、热点技术分布景观和技术主题景观等多个层面,对玉米生物育种技术领域的专利进行全景观分析。结果表明,目前全球玉米生物育种技术研究主要集中于玉米的品种特质转换、品种交叉、基因轨迹和转基因等,但在这些热点技术领域我国仍面临极大的挑战。

Faced with the increasingly serious food situation of supply and demand,accelerating biological breeding technology research has become the preferred solution to the problem.Technology landscape analysis is used to analyze patent information in the field of corn bio-breeding technology,respectively from perspectives of patent cooperation landscape,hot technologies landscape and technology topic landscape.Derwent Innovation Index is selected as a data source.The results shows that crop bio-breeding technology is mainly used in the field of characteristics of the maize varieties conversion,cross maize,gene locus and genetically modified corn.It also provides the basis for the development of Chinese corn biological breeding technology.
