Studying of lavandin clones for possibility to produce in Krasnodar region

The modern world essential-oil industry uses oil of two lavender types: spicate and spike, as well as lavandin. Lavandins are so called interspecies hybrids between lavender spicate and lavender spike, which are developed by means of natural or artificial hybridization at the border of areas of their uncultured growing. The origin places of lavandins are the mountain regions of France, Italy and Spain, where they grow as wild bushes. Artificially first lavandin was developed in 1923. Our researches were conducted in submontane zone of the Northern Caucasus in the Voznesensky branch of VNIIMK in 2014-2015. 24 lavandins clones were studied on their main biological and economically valuable traits: inflorescence yield, essential oil content in inflorescences, compound esters content in oil, essential oil yield, winter-resistance, resistance to Septoria spot, intensiveness of autumn growth, dates of beginning of the primary phonological phases of development due to methods developed at VNIIEMK. The clones were compared to the lavender variety V-34. Lavandin clones have been estimating for two years. The purpose of this research was to determine a possibility to use the parental varieties in the local conditions. The results of the clones’ studying showed the low winter-resistance and compound esters content in oil decreasing its quality. These reasons do not allow using the studied clones for cultivation in Krasnodar region. Lavandin as a highly oil crop can be produced in our region only after development of winter-resistant varieties with high perfumery assay of essential oil.
