Abstract

Two varieties of Thymus vulgaris L. (´Krajový´ and ´Winter´) and three its hybrids with T. Marschallianus Will. (variety ´Mixta´ and two accessions of variety ´Lemona´) were evaluated according the Draft Descriptor List Thymus vulgaris L. and analysed for the essential oil content and composition in years 2014 and 2015. All evaluated accessions were found morphologically and/or chemically different. Varieties ´Krajový´, ´Winter´ and ´Mixta´ were assessed as a thymol type with the thymol (39.1 – 69.6 %), o-cymene (6.3 – 24.9 %) and γ-terpinene (2.75 – 13.8 %) as main oil components. The two accessions of ´Lemona´ variety were found significantly different each other: one of them (income No. 3239) was assessed as a terpineol type with the terpineol acetate (75.7 %) and α-terpineol (16.9 %) as main oil components and the other one (income No. 2757) as a geraniol type with the geranyl acetate (±42.4 %) and geraniol (±20.8 %) as main oil components. Only the accession with income No. 3239 was proved as a ´Lemona´ variety due its citral (±9.3 %) content, though even this content is too small compare to original ´Lemona´ where about 20 % of citral was declared.
