Abstract: The Petunia hybird obtained from genetic engineering technology in 1987, which is the first transgenic flower in the world, indicated that flower breeding was marching into the molecular era. The ge-netic engneering technology have not only changed flower characteristics but also shorten breeding time. Now people understand continuously the regulatory mechanisms of flower colors through genetic engineering ways. Many enzymes and genes related to flower color were obtained. New varieties and hybirds of flowers have been bred through genetic engineering. Problems and perspectives of flower genetic engneering were briefly elucidated.

Key words: Transgenic flower
