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.
