Abstract: Genomics research is one of the fastest growing research areas in the world in recent years. The development of crop genomics research has played an important role in the effective use of modern molecular biology methods for genetic improvement of species. The sequencing of crop genomes of important crops such as rice,wheat,corn,soybean,rapeseed,cotton,vegetables,etc. has been conducted,on the basis of which the cloning and identification of genes controlling important agronomic traits is completed. The scientific literature objectively records the development overview of various disciplines or knowledge fields. The analysis of the discipline development trend based on bibliometrics may systematically summarize the current research status and hot issues of the field and evaluate the research strength and achievement output of the research institutions. This study comprehensively reveals the research and development status quo,important countries,important institutions and research topics of the crop genome in the past 10 years through the multi-dimensional and deep-level quantitative analysis of the funding of the Sino-US Natural Science Foundation projects and the SCI papers by the combination of quantitative analysis of literature and qualitative analysis by experts. The relevant research results may provide reference for future research and development layout and decision-making in related fields in China.
