To bloom the floriculture industry, breeding of new cultivars with improved ornamental and agronomic traits are required, relying on total understandings of principles during specific developmental progresses and application of new biotechnologies. At present, new biotechnologies come out every day, providing breeders with new ideas and methods on breeding of new cultivars. Here, we summarized the application of biotechnology on ornamental horticulture in the fields of cellular engineering, molecular markers, and gene modification. The gene modification in specific traits of ornamental plants was emphasized on, including morphology modification, biotic or abiotic stress resistance improvement, and postharvest life elongation. Finally, some prospects for potential biotechnologies application in future horticultural research and breeding were explored.
