A Comprehensive Review of Lavender (Lavandula spp.): Taxonomy, Pollination Biology, Essential Oil Applications and Breeding Developments

Abstract

Lavandula (Lavandula spp.) is a perennial aromatic plant belonging to the Lamiaceae family and is well known for its rich essential oil content. Lavender is widely cultivated for the extraction of valuable essential oils from its flowers and leaves. The major components of these essential oils are linalyl acetate, linalool, cineole, and camphor. The oil obtained from Lavandula angustifolia has a long history of use in various sectors. In addition to its application as a natural fragrance in medical treatments, perfumery, and the cosmetic industry, it is also used in soap production and other industrial applications. The most important active constituents in lavender flowers are the essential oils, which are colorless or slightly yellow in appearance. The quality of these oils is determined by both species characteristics and environmental factors. Breeding efforts aimed at improving the quality and yield of these oils are ongoing. In recent years, traditional breeding methods such as hybridization and selection have achieved significant progress. This advancement can be attributed to the emergence of genomic and molecular techniques, which play a key role in optimizing yield and quality traits in lavender breeding. With the increasing interest in lavender cultivation, the scientific emphasis on advanced breeding techniques for this plant has also grown considerably. The present review focuses on lavender taxonomy, uses of essential oils, pollination biology, and the developments in traditional and molecular breeding approaches.
