Drug yields and quality characteristics of clone lines of common sage (Salvia officinalis L.) population

In this study, various characters of 60 A type sage clones obtained by selection process starting from spontaneous hybrids common sage (Salvia officinalis L.) lines were investigated for flowering date, plant height (cm), fresh herbal yield (kg/da), herbal drug yield (kg/da), drug leaf yield (kg/da), drug leaf ratio (%), essential oil content (%) and composition (%). In 2011 growing season obtained ranges of values were the following: Plant height, 34.9-85.5 cm; fresh herbal weight, 835.6-3619.6 kg/da; herbal drug yield, 192.5-842.4 kg/da; drug leaf yield, 45.6-188.4 kg/da; drug leaf ratio, %17.3-38.5; essential oil content, 0.60-1.90%. Repetition of the experiment in 2012 growing season resulted in the following value ranges: plant height, 27.4-68.0 cm; fresh herbal weight, 184.0-2479.1 kg/da; herbal drug yield, 46.9-1075.9 kg/da; drug leaf yield, 26.4-638.0 kg/da; drug leaf ratio, 43.6-72.8%; essential oil content, 1.11-2.53%.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, 0.81-29.50%; β-thujone, 0.74-29.13%; 1,8-cineole, 0.98-30.53% and camphor, 0.41-19.10%. In 2012 season the values obtained for these oils were α-thujone, 0.98-53.21%; β-thujone, 2.18-54.73%; 1,8-cineole, 2.76-34.03% and camphor, 6.36-29.15%. 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.
