Abstract: Embryo rescue techniques play an important role in saving abortive embryos, preventing embryo degeneration at early development stage and developing new triploid and polyploid. There were three main methods of plant embryo rescue: in vivo embryo transfer, embryo in vivo culture and embryo in vitro culture. In the process of plant embryo in vitro culture,according to the development degree of the plant embryo which was needed to save, three training modes were set up,that is, in vitro ovary culture, ovule culture and immature embryo culture. A plenty of researches have been shown that embryo age, medium and medium phase, culture conditions, osmotic pressure, growth regulator, complementary materials, genotype and so on, played a great role in the success of embryo rescue. Therefore, embryo rescue techniques as an adjunct to conventional breeding methods will have further room for improvement in such aspects as embryonic age limit and plant regeneration rate. In addition, combining embryo rescue techniques with molecular biological research methods, genetic transformation is expected to stabilize different characteristics of the new germplasm, and innovate the plant resources.
