Abstract: The transgenic breeding technology is an important way for crop genetic improvement. Through bibliometrical and clustering analysis of subject headings on SCI papers in crop transgenic breeding field, this paper intended to obtain the main research direction, development situation and key technology that restricted its development in transgenic crop breeding field. The results showed that the number of published papers in China took the leading role with 2 956 papers, occupying about 22.1% of the total. The average cited time for papers in Chinese was 7.9. The Chinese Academy of Sciences published the largest number of papers, which research areas covered definition of ideal plants, resistance, cell development, zinc finger proteins implicated in different cellular processes involved in plant development and stress responses, biological metabolism and disease resistance, resistance mechanisms, etc. using model plants. The 3 major crops in transgenic research were rice, corn and wheat. These results provided reference for Chinese researchers to accurately grasp the development trend and key scientific issues in crop transgenic breeding field, and also provided scientific alliance for scientific management organizations in developing supporting policies and determining key projects in crop transgenic breeding area.

Key words: crop, transgenic, bibliometric, development situation

摘要： 转基因育种技术是作物遗传改良的一个重要技术，通过对作物转基因育种领域的SCI论文进行文献计量学、主题研究领域分析 ，以期获得作物转基因育种领域主要研究方向、发展态势以及制约其发展的关键技术。结果表明，中国的发文数量排名第一， 高达2 956篇，约占发文总量的22.1%，篇均被引频次为7.9次。机构中以中国科学院发文最多，其研究涉及一些理想植物植株 模型，抗性、细胞发育、胁迫反应的锌指蛋白功能分析，利用模式植物研究生物代谢、抗病、抗逆性的机制规律等。作物转基 因研究涉及最多的前三种作物分别为水稻、玉米、小麦。该结果也为我国作物转基因育种领域科研技术人员准确把握领域内发 展趋势和关键科学问题提供参考，为科研管理机构制定作物转基因育种领域扶持政策和确定重点扶持领域提供科学依据。
