Comparative characteristics of the basic economic features of inter-specific hybrides of the genus lavandula

Abstract

The aim of the work was to obtain comparative data on the main economic characteristics of the four lavandins to identify a hybrid with high quality essential oil. Determination of the chemical composition of essential oil of lavandin interspecific hybrids bred in NBG-NSC, allows to judge the prospects for their use in the perfume industry. Cultivars of lavandin Temp (control), Snezhny Bars and lavandin genetype Brovka, № 53 were selected as the objects of study. Crop accounting was carried out according to the method of field experiments by Dospekhov. The mass fraction of essential oil in plants was determined by hydrodistillation. The composition of the volatiles substances was determined by gas chromatography-mass spectrometry. Based on the results, the following hybrids were identified: Brovka with a high yield of flower raw materials of 118,8 c / ha, Snezhny Bars with a high linalool content up to 62,5%. Hybrid No.53 was characterized by a high yield of essential oil on a wet weight up to 4,2%, a linalyl acetate content up to 31.1% and a low content of camphor, 1,8-cineole and borneol. It is shown that the essential oil of hybrid No. 53 is promising for use in perfumes.
