31. SUMMARY The propagation and improvement of ornamental plants with desired traits can be achieved by creating novel variation that would benefit the floriculture industry. The genetic variability can be induced by physical and chemical mutagen treatments of leaves, cuttings, and in vitro grown plant materials. Despite its effectivity and efficiency in producing mutants, mutation breeding needs to be done in a safe and controlled facility. Induced mutations consequently have a high potential for bringing about further genetic improvements in ornamental plants.
