Abstract: To create hybrids of different varieties of Salvia sclarea L., with high productivity, resistant to drought, frost and wintering, initial breeding material was used with a pronounced variability in key quantitative traits that directly influence productivity: plant height, inflorescence length, number of first and second degree branches of the inflorescence. The biological material used in the research consisted of 25 simple, triple, double, stepped and complex F7 - F8 hybrids of sage, in the second year of vegetation. The studied biomorphological traits were included: plant height, inflorescence length, number of first and second degree branches of the inflorescence. The essential oil content was determined by hydrodistillation in Ginsberg apparatus. Under the weather conditions of 2024, the evaluated hybrids developed floral stems ranging from 99.9 cm to 141.5 cm. The tallest plants were attested to the double hybrid combination [(V-24-86 809 S3 x 0-33 S6)F7 x (S-1122 528S3 x S.s.TienShan/sud)B5)]F7 and the stepped hybrid [M-69 655 S9 x (K-36 x 0-41)F2 x 0-19)F1 x L-15)F7]F7, which recorded 141 cm each. The length of the inflorescence varied between 51.9 and 74.7 cm. The panicle height in the plant is within the limits of 49 – 59%. The largest inflorescences were recorded in the plants of the complex hybrid [(M-44 S4 x L-15)F1 x L-15)F7 x (K-36 x 0-41)F2 x 0-19)B5)]F7 – 74.7 cm, and the inflorescence length/plant height ratio was 54.9%, as well as in the stepwise hybrid combination [(K-36 x 0- 41)F2 x 0-19)F1 x 0-22)B4 x L-15)F6 x Cr.p.99 S11)]F7 with a panicle length of 70.2 cm and the inflorescence share of the plant height – 55.0%. The best correlation between plant height and inflorescence length was observed in triple hybrid [(S-1122 60 S10 x (M-69 429-82 S3 x 0-40S5)F7)]F7 – 59.8%. The plant inflorescences had a total of 37.4 – 64.6 branches, including 13.0 – 21.0 first-degree branches and 28.2 – 45.0 second-degree branches. The highest number of branches was recorded by the complex hybrid [(M-44S4 x L-15)F1 x L-15)F7 x (K-36 x 0-41) F2 x 0-19)B5)]F7 and the step hybrid combination [(K-36 x 0- 41)F2 x 0-19)F1 x 0-22) B4 x L-15)F6 x Cr.p. 99 S11)]F7 – 60.2 and 64.6 branches, respectively. The content of essential oil in inflorescences ranged from 0.673 to 2.834 % (dry matter). Seven hybrids were selected that stood out with a very high essential oil content of 1.424 – 2.834% (dry matter). Exceptional in this character was the hybrid [(0-57 S5 x 0-21)F2 x Dacia 50 I an)]F8. In 2020, this hybrid synthesized and accumulated 2.163 % (dry matter) essential oil, in 2022 this important index was 1.889% (dry matter), and in the reference year it had the value of 2.834% (dry matter). The research carried out resulted in the selection of hybrids with a high content of 1.424 – 2.834 % essential oil, recalculated to dry matter. These hybrids present a valuable genetic material for the creation of Salvia sclarea L varieties.
