Abstract: The system of soybean somatic embryogenesis genetic transformation is the effective way to improve the genetic stability of exogenous gene and overcome the chimera. Therefore highly efficient and stable soybean somatic embryonic tissue culture system should be established and widely used in the genetic transformation of soybeans, which is the important research content to improve the soybean genetic transformation. This paper described the research progress of soybean somatic embryogenesis regeneration system from the regeneration system of soybean somatic embryos and transgenic research methods ,and then discussed the factors which affecting the genetic transformation of soybean somatic embryogenesis.
