Current status and biotechnological advances in genetic engineering of ornamental plants

Cut flower markets are developing in many countries as the international demand for cut flowers is rapidly growing. Developing new varieties with modified characteristics is an important aim in floriculture. Production of transgenic ornamental plants can shorten the time required in the conventional breeding of a cultivar. Biotechnology tools in combination with conventional breeding methods have been used by cut flower breeders to change flower colour, plant architecture, post-harvest traits and disease resistance. In this review we describe advances in genetic engineering that have led to the development of new cut flower varieties.
