We have developed and assessed intraspecific Lavandula 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 in the Ginsberg apparatus 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. |
