The varieties of Salvia sclarea provides a production of 15.4– 19.5t/ha of inflorescences and guarantees the yield of 54.5–73.5 kg/ha of essential oil. The essential oil content of Lavandula angustifolia varieties in the dry years is higher than in the years with normal atmospheric depositions. The productivity of the lavender varieties is higher (7,4 -7,7 t/ha) of inflorescences and 155,2- 179,2 kg/ha of essential oil. We can conclude that the varieties are part of different groups of maturity, high production of raw material, high content of essential oil. They are resistant to frost, winter and drought.
Evaluation of inbred lines of Salvia Sclarea L. [Articol]
(Editura USM, 2025) Balmuș, Zinaida; Cotelea, Ludmila; Butnaraș, Violeta
In the process of breeding the species Salvia sclarea L., a fundamental objective was to diversify the initial breeding material and select lines with valuable quantitative characters and increased content of essential oils. As a result of research conducted with a large number of inbred lines, it was found that there are lines with full flowering in the first year of vegetation, as well as lines with an increased content of essential oils. Finally, lines with an essential oil content exceeding 2% (dry matter) were identified: M-69 453-82 S16 – 2,191%; M-69 428-82 S16 – 2,227%; M-69 815-82 S16 – 2,140%. Lines with essential oil content exceeding 1%: AP 2-11 S6– 1,642 %; AP 11-11 S6– 1,642 %; AP 28-11 S6– 1,221 %; AP 30-11 S6– 1,912 %; AP 66-11 S6– 1,643 %; AP 67-11 S6– 1,573 %; NC 6 -11 S6– 1,356 %; NC 4 -11 S6– 1,358 %; NC 19 -11 S6– 1,499 %; NC 38 -11 S6– 1,646 %; NC 98 -11 S6– 1,810 % etc. Thus, the selected lines were subjected to inbreeding during the flowering phase, in order to reproduce promising lines, which will later be included in breeding programs. The aim of the investigations was to create, evaluate and select initial breeding material with high-performance genetic potential.
Evaluation of new hybrids of Salvia Sclarea L., with high essential oil content [Articol]
(Editura USM, 2025) Cotelea, Ludmila; Balmuș, Zinaida; Butnaraș, Violeta
The importance of the species Salvia sclarea L., its multiple uses, have stimulated genetic and breeding work to create new hybrids with high essential oil content, resistant to drought, frost and wintering. The biological material used is 33 F2 hybrids, simple, triple, double, stepped, complex, in the first, and second year of vegetation. The evaluated hybrids are distinguished by high height, long, compact inflorescences, due to the large number of branches (40 – 52) of the first (12.6 – 17.8) and second (22.4 – 35.6) order of the inflorescence. Determination of the essential oil content has shown that 72.7% of the evaluated hybrids have accumulated an essential oil content greater than 1,000%. In the first year of vegetation, the oil content recorded values ranging from 0.924 – 1.992%, and in the second year, 0.745 – 1.761%. 8 F2 hybrids with very high essential oil content of 1.409–1.761% were selected. The simple hybrid [AP115-11 S4 x AP 112-11 S4]F2 was highlighted for this character, with 1.587% in the first year and 1.761% essential oil recalculated to dry matter, in the second year of vegetation.

The evaluation of quantitative character indices – lant height and diameter, number of flowering stems per plant, inflorescence and floral spike length, number of whorls on the floral spike, raw material yield, and essential oil content – allowed for the characterization and assessment of each lavender variety-clone. The varieties under study synthesized and accumulated an essential oil content at standard humidity (60%) exceeding 2% (Svetlana – 2.199%; Alba 7 – 2.188%), and on dry matter basis exceeding 5% (Svetlana – 5.498%; Alba 7 – 5.472%). Raw material yield varied from 3.6 t/ha to 7.7 t/ha depending on the variety, with the most productive being Svetlana (7.7 t/ha), Alba 7 (7.3 t/ha), and Favoare (6.7 t/ha). The essential oil yield in the evaluated varieties-clones ranged from 11.6 kg/t to 22.0 kg/t. The highest yields were recorded in the varieties: Svetlana (22.0), Alba 7 (21.8), and Favoare (17.1) kg of essential oil per ton of fresh inflorescences.
