Mutation is the sudden heritable change that occurred in an organism. It may be caused by spontaneous or through artificial induction and the resulted mutant shows change in the gene or chromosomes. Induced mutagenesis techniques have successfully produced and commercialized quite a large number of new promising varieties in different crops worldwide, including ornamental plants. Induced mutagenesis has been most successful in ornamental crops. The improvement achieved through mutation breeding in ornamental crops includes compact growth, attractive variegated leaves and novel flower colour and shapes. Ornamental plants with a rich variety of flower colors and shapes are highly prized, and the production of mutant cultivars that differ in these traits is in demand because all other growth habits are identical. Many species of ornamental plants, such as chrysanthemum (Chrysanthemum spp.), rose (Rosa spp.), and carnation (Dianthus caryophyllus), are vegetatively propagated, making it relatively easy to propagate mutants. This review not only provides examples of successful mutation breeding results using physical and chemical mutagens, but it also describes research on mutagenesis and compares results of gamma ray, EMS and DES using ornamental plants.
