Abstract: Dandelion is historically recognized as weedy plant and is familiar to us as medicinal herb. It comes into fashion as a new type of vegetable in recent years. Though many research works on the chemical constitutes, medical mechanism，caryotype，cell culture and molecular biology of dandelion have been carried out，rare biotechnological modification has been done. In this review，combined with our works，we reviewed the research situation of dandelion and focused on the trend of the biotechnological breeding for salt tolerance，in order to develop dandelion application further.
