For the selection of donors with valuable characteristics for breeding, 39 thyme accessions were evaluated in three years according to a staggered schedule. The criteria investigated were: winter hardiness, beginning of flowering, growth height, yield of the dry herb, content of essential oil, composition of the essential oil, DNA content of cell nuclei and number of chromosomes. The most strongly varying traits between the populations were the yield of dry herb, the content of essential oil and the content of volatile phenols with coefficients of variation (CV) between CV 40% and 50%. The largest variation within a population was detected for the yield of dry herb (CV 25-46%) and the content of essential oil (CV 17-48%). The homogeneity of the populations was different. The minimal average coefficient of variation of all traits (CV 19%) was determined in the population of the cultivar 'Varico II' and in a population from Lithuania. The ploidy level of T. vulgaris was diploid (2n = 30).
