###### Abstract
The highest proportion of \(\alpha\)-pinene was in all TS phenotypes, especially in TIV (11.9%), and in phenotype CII (11.9%). A distinctly lower proportion was identified in FIV (0.7%). The highest proportion of myrcene was also observed in the five TS phenotypes; TI had the highest proportion among the TS phenotypes (29.9%). The highest proportion of, \(\beta\)-pinene, 3-carene, \(\gamma\)-terpinene, terpionolene, borneol, and menthol occurred in CII among all phenotypes, while the highest proportion of \(\alpha\)-cedrene, \(\beta\)-caryophyllene, \(\alpha\)-humulene, cis-nerolidol, geranyl isobutyrate, caryophyllene oxide, \(\beta\)-eudesmol, and phytol occurred in CI (almost all components of sesquiterpenes). However, the CS variety also had the lowest amount of essential oil compared to other investigated varieties. FIII had the highest proportion of \(\alpha\)-terpinene (0.6%) and fenchone (0.2%), and TI had the highest proportion of p-cymene (0.1%). The highest proportion of borneol (0.2%) and geranyl acetate (0.3%) was in FIV. FII contained the most \(\alpha\)-terpineol (1.0%). Terpenoids p-cymene, camphor, isoborneol, \(\beta\)-citronello, and neryl acetate had contents lower than 0.1% or were undetectable. Terpenoids have a great impact on human health [26]. Almost all listed components have anti-inflammatory effects, including myrcene, \(\beta\)-caryophyllene, caryophyllene oxide, humulene, \(\alpha\)-pinene, linaolool, limonene, terpionolene, \(\gamma\)-terpinene, nerolidol, borneol, fenchone, and \(\beta\)-eudesmol. Some components have positive impacts on cancer and tumor treatments, such as \(\beta\)-caryophyllene, which also has a synergistic anticancer effect with humulene. Iso-caryophyllene, humulene, \(\alpha\)-pinene, and linaolol have antitumor activity [27]. All phenotypes of CS and TS had high proportions of caryophyllene oxide, which has a positive effect on type 1 and type 2 diabetes, cardiovascular diseases, and hypertension [27; 28]. CII had the highest proportion of \(\beta\)-pinene, which has an important role in the regulation of diabetes, cancer, obesity, and other chronic diseases. Myrcene, terpionolene, linaolol, and nerolidol have sedative effects. Humulene and limonene treat depression, and humulene has also been used in traditional medicine for treating insomnia, anxiety, delirium, and depression. With a significantly higher proportion of \(\alpha\)-humulene, the CI phenotype could be used in further pharmaceutical research, especially if the total amount of essential oil could be increased in breeding procedures or affected by the environment. This phenotype also had a significantly higher proportion of \(\beta\)-eudesmol, which stimulates appetite [27]. The total amount of detected monoterenes was higher than that of sesquiterpenes in all three varieties [6; 28]. Comparing the investigated varieties, the highest monoterpene content (44.89%) occurred in TS, while CS varieties had the highest amount of sesquiterpenes (28.67%). In the group of monoterenes belong compounds \(\alpha\)-pinene, camphene, \(\beta\)-pinene, myrcene, 3-carene, \(\alpha\)-terpinene, p-cimene, limonene, \(\gamma\)-terpinene, fenchone,terpinolene, linalool, camphor, isoborneol, borneol, menthol, \(\alpha\)-terpineol, \(\beta\)-citronellol, neryl acetate, and geranyl acetate, while in the group of sesquiterpenes belong compounds \(\alpha\)-cedrene, \(\beta\)-caryophyllene, \(\alpha\)-humulene, cis-nerolidol, geranyl isobutyrate, caryophyllene oxide, \(\beta\)-eudesmol, \(\alpha\)-bisabolol, and phytol. A difference between varieties was observed when the average of essential oil components in individual phenotypes was compared (Figure 1). Principal component (PC)1 explained 39.44%, and PC2 explained 25.90% of the variance. Phenotypes of FS and TS were clustered together, while phenotypes of CS were separated. Considering the average amount of compounds in essential oil phenotypes within FS and TS, they were more uniform than CS phenotypes.
