Lavender is a polymorphic plant that is represented in nature by wide diversity. This can
help to find signs for obtaining economically valuable forms, propagated after selection by the
vegetative way. It was selected samples of Lavandula angustifolia Mill. cv. Prima from seed
generation to create new high-productive cultivars. They differed by the complexity of
morphological characteristics such as the number of flowering shoots, number of whorls in
inflorescences, flowers in a whorl. Among selected forms, the best economically valuable signs
(essential oil content and its component composition) characterized forms 1-13-14 and 915
that propagated by the vegetative way.
Cv. Syneva Nadii. Shrub of middle size, compact form, height of 65 cm, and diameter of 80
cm. The flower shoots straight, green, with middle thickness. Three-year-old plants have
approximately 200 flower shoots. The inflorescence is elongated, length of 12–14 cm. Calix of
the corolla is violet. Corollas are richly violet, moderately pubescent. Diameter of an
inflorescence of 2 cm. A number of whorls of 10–11. The number of flowers in the inflorescence
of 90. Leaves grey-green, narrow 5.5 cm in length, 0.4 cm in width.
These plants are characterized by a mass fraction of essential oil 1.3 % of fresh weight
(FW) or 3.3 % of dry weight (DW). The content of linalilool in essential oil, which is a valuable
component of 78.8 %.
Cv. Lidiia. Shrub of middle size, compact form, the height of 60–70 cm, and diameter of 80
cm. The flower shoots are straight, green, thick, with a diameter of 25 cm, length of 30 cm.
Three-year-old plants have approximately 100 flower shoots. Length of inflorescence 7–9 cm.
Calix of the corolla is green. Corollas big, dark-violet, moderately pubescent. Diameter of
inflorescence 2 cm. A number of whorls of 8–10. A number of flowers in whorl 14–16. Leaves
are grey-green, length of 5.2 cm, the width of 0.7 cm.
The mass fraction of essential oil varied from 1.1 to 1.3 % FW or 2.8–3.3 %. Linalyl acetate
is a valuable component of essential oil and its content of 48.10 %.
Obtained cultivars are frost-resistant and tolerant to pest damage diseases. Plants had a
high content of essential oil and valuable components. They can be successfully used both in
the essential oil industry and in landscaping the Steppe zone of Southern Ukraine.

Keywords: Lavandula angustifolia, fruits, cultivars, biochemical composition.
