The ranges of the clone mean values were obtained for drug leaf yield as 45.6 and 188.4 kg da-1 in 2011, and 26.4–638.0 kg da-1 in 2012 growing season, and for essential oil content as 0.60 and 1.90% in 2011 and 1.11–2.53% in 2012 growing season, respectively. In the sage clones analysed, the most important essential oil compounds determined were α-and β-thujone, 1.8-cineole and camphor. In 2011 growing season, the contents of these volatiles were the following: α-thujone, 0.8–29.5%; β-thujone, 0.7–29.1%; 1.8-cineole, 1.0–30.5% and camphor, 0.4–19.1%. In 2012 the chemical distributions were α-thujone, 1.0–53.2%; β-thujone, 2.2–54.7%; 1.8-cineole, 2.8–34.0% and camphor, 6.4–29.2%. Considering the drug leaf yield, volatile oil content and quality, 10 different clones out of 60 A clones (3, 8, 11, 14, 21, 26, 27, 35, 41 and 51) were chosen and will be advanced to B clones in repetitive yield experiments for further evaluation.
