基于核心专利识别视角的作物生物育种核心技术研究
Research on Core Technology of Crop Biological Breeding Based on the Perspective of Core Patent Identification
摘要
Abstract
Biological breeding is the core of seed industry innovation and an important measure to tackle key technology of seed sources.Clarifying the core technology of crop biological breeding has guiding significance for China's strategic deployment of breeding technology research and development(R&D),cracking the"bottleneck"problems of seed sources,achieving modernization of the seed industry,and country construction with powerful seed industry.Based on the Derwent Innovation patent database,the core characteristics measurement index(CCI)was constructed based on core technical features,and combined expert intelligence to identify core patents in the field of crop biological breeding.Through quantitative analysis and text mining,the layout overview of core patents in the field was analyzed from the perspectives of R&D institutions,layout areas,and technology distribution,and R&D hotspots and key points evolution trends of core technologies in crop biological breeding were concluded.Furthermore,five core technology themes of crop biological breeding had been identified with expert analysis,and prospects for the future research and industrialization of biological breeding in China were presented based on transgenic technology and genome editing technology according to the current development status of crop biological breeding core technology in China.关键词
