Фото: Brenici Mircea
Alba 7 is a late variety, it blooms 3-4 days earlier than the C – 90 variety. The plant is a perennial semi-shrub, with a waist of 57.1 cm, plant diameter – 85.8 cm and with 484 flower stalks of a compact shape . The flowers until they open have a white calyx and floral button, the corolla inside is violet-bluish. The fruit is oblong, smooth, glossy and brown. MMB=0.6 g. Evaluation of the variety in comparative competition crops during the years 2006 – 2013 demonstrated that the variety is characterized by high production of raw material, high content of essential oil and high yield of essential oil.
Thus, the average raw material production is from 8.3 t/ha to 12.8 t/ha, the volatile oil content is 4.441 – 5.376 % (s.u.). The essential oil production is 143.3 – 245.0 kg/ha. The variety is characterized by high resistance to drought, frost and winter. It is intended for the production of essential oil and pharmaceutical raw material.

2022
Under production conditions of the Alba 7 variety, in the summer of 2022, on the plantation of the 2nd year, the planting scheme of 1.5 x 0.5 m, a harvest of inflorescences of 4 560 kg was obtained, from which were extracted 64.2 kg of essential oil. The productivity of essential oil relative to one ton of green mass of inflorescences was 14 kg of oil (1.4%). The results of the chemical analysis of the obtained essential oil is shown in the image on the right, in tabular form.
