The floriculture industry is changing rapidly not only in India, but around the world. Flowering crops, particularly flower production, account for a significant portion of the country's total agricultural output. Mutation breeding has been more effective in ornamental plants because phenotypic characteristics such as flower colour, shape, and size, as well as chlorophyll variation in leaves, are easily detectable. In mutation breeding, only artificial mutations are used. Induced mutation could be one method of generating genetic diversity. Induced mutagenesis is a well-established process for plant improvement in which plant genes are altered by using chemical or physical mutagens on seeds or other plant sections. Gamma rays have been most successfully used in induced mutation, and several new varieties have been produced and published in various flower crops and ornamentals.
