Abstract 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.
