Lavandula angustifolia Mill., lavender is a perennial shrub from the Lamiaceae family, a medicinal, aromatic, as well as melliferous and decorative species of Mediterranean origin. Lavender and the products derived from this species have been used for ages as an therapeutic agent in traditional medication in Asia, Europe, antique Greece and Rome. The utilization of lavender for medicinal, phytotherapeutic and pharmacologic reasons is due to the essential oil and its components separated from inflorescences. A particular area includes the studies carried out to develop new hybrids and cultivars that are resistant to abiotic factors that would ensure an enhanced production of inflorescences with a higher content of essential oil and a quality that corresponds to the purpose proposed for utilization. Such studies have evidently intensified during the last decade as a consequence of the climatic changes, slow but steady processes of global warming, transformation of some zones into a desert including in south-eastern Europe where farm crops are increasingly impaired by drought and scorching heat while L. angustifolia, Salvia sclarea and S. officinalis cultivars have ensured more enhanced production of high quality essential oil during the dry years than in the years with normal atmospheric precipitations. This work also belongs to this area of research. Were created and assessed intraspecific L.angustifolia Mill. hybrids. The indices of the quantitative characters have been shown to vary between the hybrids and maternal forms. The content of essential oil quantified via hydrodistillation is much higher (3.939 – 5.480%, dry matter) in the hybrids produced than in the maternal forms from which they originated (2,722 – 3,413%). The effect of heterosis for the essential oil content varies considerably in different hybrids derived from different maternal parents and constitutes +37,8 – +110,5%. The quantitative and qualitative analyses of the essential oil assessed with the aid of GC-SM techniques have demonstrated considerable differences of the oil in different hybrids depending on the maternal form. The number of the components identified in the essential oil ranges between 18 and 38. The major components in the essential oil are as follows: linalool (24.15 – 50,84%); linalyl acetate (27,29 – 44,40%); α – terpineol (3,82 – 4,84%); terpinen-4-ol (1,11 – 9,21%); lavandulol acetate (0 – 2,22%). The hybrids with a very high content (4,939-6,164 %, dry matter) of essential oil, different vegetation period from early- to late-ripening and resistant to drought have been selected. Their cloning has resulted in new varieties named Fr.5S8-24, VM-18V and Fr.8-5-15V.
