Abstract：Soybean (Glycine max) is an important grain and oil crop in the world, which provides abundant protein and oil sources for human and animals. The successful commercial utilization of transgenic technology in soybean has become a classic case of biotechnology in promoting crop production. In recent years, the rapid development of new generation biotechnology, such as genome editing, has provided new opportunities for further improvement of soybean agronomic traits. Recently, genome editing technology represented by CRISPR/Cas technology begins to be widely used in genetic improvement of soybean, which shows powerful potentials on improving quality, regulating growth period and stress resistance. This review summarizes the latest research progress in this field from the development of genome editing technology, the application of genome editing technology in soybean genetic improvement and the main problems in current application of genome editing technology in soybean, which provides a reference for the work of using genome editing technology as a tool to accelerate soybean genetic improvement.
