Abstract: In this paper, the state in the use and the proceeding in the research on the choice of rootstocks for citrus in China within twenty years are summarized. The leading rootstock is trifoliate orange. It is incompatible with the scions during the late period, and it has not the resistances of deep and harden soil, saility soil and the dramatical and huge change in the air temperature, and it is infected with exocortis, dam ping-off, bacterial wilt and fire blight easily. So it needs improving or alternating urgently. Some good germplasms for rootstocks for citrus have been picked out and introdcted into. Some somatic hybrids used as rootstocks have been selected through somatoplasm fusion. Some methods in early identification on stability of inherence and copatiblity and dwarf are explored, and they need improving. Rootstocks having some virtues have been selected, but they cannot take the leading place of trifoliate orange. The research method that the rootstocks are only compared with each other should be altered into that the rootstocks and given control measures or environmental conductions are connected to make the rootstocks compared with each other. The focus and the subjects of the study in the future in China are still studies on the investigation, introduction, selection, breeding and utilization of germplasm for rootstocks for citrus.
