Transgenic flowers for novel colour are the one in which genes are modified or introduced through genetic engineering and has integrated in its genome for pleasing look. Flower colour is a key element in consumer selection between ornamental varieties available in the market place. Thus introduction of novel colour, forms, through genetic engineering by the way of producing transgenic flowers is likely to have large influence on the floriculture industries. In this review we have describe the experimental data of manipulation of flower for novelty by the different methods of genetic engineering and have compared the results in terms of colour change and stability for long term. Metabolic engineering involved the manipulation of anthocyanin biosynthesis pathway, down and up regulation of flavonoid anthocyanin pathway. Molecular breeding included gene silencing technology for colour modification in transgenic flowers. Among different types genetic engineering tools RNAi technique found to be superior and powerfull method to obtain transgenic flowers with aimed phenotype. This modification of flower colour has applied both for ornamental as well as commercial flower crop species.

Key words: Transgenic flowers, RNAi technique, Metabolic engineering
