摘　　要：本文以Web of Science SCI引文数据库与CABI Abstract数据库为数据源,以中、美、法三个国家级农业科研机构为例,采用内容词分析、聚类分析以及关键词机构归属度等方法,着重分析作物遗传与育种的研究主题。结果显示三大机构在重点研究主题上呈现相似的分布格局,又各具特色:中国农业科学院在遗传与育种领域更注重基础性研究,在非生物胁迫等方面研究较为突出;美国农业研究局青睐于对作物抗性育种、抗虫性等方面的研究;法国农业科学院注重遗传工程研究。Based on Web of Science SCI citation database and CABI Abstract database as the major data source, this paper takes three national agricultural research institutions in China, USA, France as examples, with the method of content words analysis, cluster analysis, institution relevancy of keywords and so on, emphatically analyzes the research topics of the field of plant breeding and genetics. Results show that in the main research topics, this three institutions presents similar distribution, but each has its own characteristics. In the field of plant breeding and genetics, CAAS pays more attention to basic research, especially the abiotic stress research; ARS favors resistance breeding of erops, such as insect resistance, INRA focuses on genetic engineering research.
