2013-2018年全球玉米育种研究发展态势分析

以Web of Science数据库为主要数据来源，基于文献计量学方法，借助CiteSpace和VOSviewer可视化工具，从研究实力及分布、研究前沿、研究热点和主题演进等方面对2013-2018年玉米育种研究的科技论文进行全面分析。结果表明：中、美两国是全球玉米育种研究兼具科研实力和影响力的领军者，中国农业科学院、美国农业部农业科学研究院和中国农业大学是重点研究机构；国际合作由区域内部逐渐向跨地区合作模式转变；作物驯化、主效数量性状基因/位点、基因选择和利用辐射创造突变体及定位研究是玉米育种的研究前沿。在这种形势下，我国应重视科研成果质量，加强国际合作交流，合理布局研究力量，把握发展机遇，追求科研创新，提高我国玉米育种的全球影响力。

Development Trend Analysis of Global Maize Breeding Research from 2013 to 2018

Taking Web of Science database as the main data source, based on bibliometrics, citeSpace and VOSviewer visualization tools were used to comprehensively analyze the scientific and technological papers on maize breeding research from 2013 to 2018 in terms of research strength and distribution, research frontiers, research hotspots and theme evolution. The results showed that China and the United States were the leaders of both scientific research strength and influence in the field of Maize Breeding in the world. Chinese Academy of Agricultural Sciences, United States Department of Agriculture/Agricultural Research Service and China Agricultural University were the key research institutes. The international cooperation has gradually changed from intraregional cooperation to cross-regional cooperation. Crop domestication, major quantitative trait locus, genomic selection and radiation hybrid qtl mapping are the research frontiers in Maize breeding. Under current situation, China should attach importance to the quality of scientific research papers, strengthen international exchanges and cooperation，rationally arrange research forces, seize development opportunities, pursue scientific research and innovation, and improve the global influence of China in Maize Breeding.
