Floral fragrance and flower color are important ornamental traits of flower crops， which are key factors that determine flower quality and affect flower economic values. Therefore， cultivating new flower varieties with rich floral colors and pleasant flowers has long been the main breeding goal of horticulturists. As a representative of bulb cut flower varieties， Freesia hybrida has bright flowers and pleasant aroma. The key structural genes FhCHS1， FhDFR， Fh3GT， Fh5GT that control the synthesis of anthocyanin in Freesia and the key structural genes for terpene synthesis， FhTPS1 to FhTPS14， are highlighted， in addition to the fact that small amino acid differences between the sequences of the natural variants of the TPS genes in the wild species drive the enzyme's catalytic activity and product specificity， laying the groundwork for elucidating genetic differences among floral scents species. The synthesis of anthocyanin is also regulated by MYB-bHLH-WD40 in addition to structural genes， and the synthesis of floral scent is regulated by FhMYB21L2 and FhMYC2， in addition to the co-regulation of the expression of the flavonol synthase gene， FhFLS2， by FhMYB21L2. Finally， we look ahead to the potential application of the synthesis of anthocyanin and terpenoids.
