    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.

    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.
