Abstract:

Mutagenesis breeding is a fast and effective breeding method, which has special important significance for the improvement of ornamental plant varieties. Orchids have important ornamental, medicinal, edible and/or cultural value, and broad market prospects. Studies have shown that mutagenesis causes the character changes including plant type, leaf character, flower number, flower size, flower type, flower color, flowering time, ornamental period, insect resistance, disease resistance, stress resistance in orchids, and to date, at least 930 mutants and 16 new orchid cultivars have been generated. This paper reviews the achievements of mutagenesis breeding research in orchids, clarifies current situation and factors affecting the effect of orchid mutation breeding, summaries mutation mechanism of orchids, and finds the methods to further improve the efficiency and effect of orchid mutation breeding. It would provide references for creating new varieties of orchids by better utilizing mutation breeding technology and further clarifying the mutation mechanism of orchids.

Key words: Orchidaceae, mutagenesis breeding, mutant, cultivar, research progress
