Abstract: Protop last fusion is a potential method, by which the target characters, especially ones controlled by multigenes or un-cloned genes, can be transferred. The research on protoplast fusion of Compositae
plants has been focused on Helianthus, Cichorium, Dendranthema, Lactuca genera etc, and the purposes are concentrated on resistance improvement, male-sterile materials, polyploid induction and obtainment of intermediate materials. In this paper we reviewed the achievements of protoplast fusion of Compositae plants, and discuss on existent questions at present and further improvements.

Key words: Compositae, Protoplast fusion, Review
