Abstract: Dwarf is one of essential agronomic features and the important research field in life science as well as the hot area in plant breeding. Based on dwarf origins, dwarf can be divided into mutated dwarf and spontaneous dwarf. The mutated dwarf includes physical mutation,  chemical mutation and  biological mutation. Much more researches about physical mutation have been done, especially in space mutation area. The study of dwarf mechanism mainly focused on plant endogenous hormone, including gibberellins,  brassinolides and auxins etc. Regarding the concrete dwarf mechanism of different plants, no clear classification and detailed researches are available now. This paper summarized the origins of dwarf mutant and their dwarf mechanisms, the dwarf origins and mechanism of the dwarfish plants mutant.

Key words: Dwarf mutant, Dwarf origins, Dwarf mechanism
