In everyday life fragrance plays an important role in many biological functions. Flowers have been known for a long time to be source of sweet fragrance. For centuries roses have played an important role in human society. Their ornamental value is not only for their size and shape. The abundance of flowering and their fragrance have attracted attention. As plant breeding has evolved over the last centuries into a science rather than art, and plant production has become an industrial process, the focus has changed to plant production parameters rather than flower fragrance. This became even more pronounced after the emphasis is more on vase life and the flower fragrance had a negative correlation with the vase life of cut roses. In case of roses this has led to the development of many beautiful roses in the sense of flower colour and shape with an enhanced vase life but with only a portion of the fragrance of earlier cultivars and wild species. Rose flowers provide one of the most important essential oils which are indispensable in perfumery production. More than 400 volatile compounds have been identified by GC-MS and it has been found that most of these substances belong to the following three major biosynthetic pathways: phenyl propanoids, fatty acid derivatives and terpenoids. Most modern rose cultivars lack a distinct scent because selection for disease resistance, long vase life as well as appearance of the blossom dominated the breeding activity for many years. About 20% of all rose varieties known today are classified as fragrant. The fragrance profiles range from flowery aspects to fresh citrus, spicy aspects and a typical musk scent. The three species Rosa damascena, R. centifolia and R alba are predominantly used in the production of rose oils. There are actually over two dozen different sorts of rose scents that contribute to the rose's fragrance, with some roses having a mixture of these various perfumes. The seven basic scents that are most often found in hybrid tea roses include rose, nasturtium, orris, violet, apple, lemon, and clover. Some of the other scents are fern or moss, hyacinth, orange, bay anise, lily-of-the-valley, linseed oil, hone, wine, marigold, quince, geranium, peppers, parsley, and raspberry. Some of the famous garden rose varieties known for their fragrance are
