Abstract: 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.
