The subjects of the study were the common oregano and hyssop medicinal, the samples and collection samples of which were taken from the collection of VIR, samples of foreign selection and endemic (local) forms of various regions of the Tyumen region. All collected samples were brought to the experimental field, where they were placed according to the scheme of field experience. The experiment was founded in 2013 in a couple of seedlings. The accumulation of essential oil is positively influenced by temperatures from 20 to 25 °C, and the amount of medicinal raw material is at temperatures from 15 to 20 °C during the period of plant growth. Of the twenty-six specimens of hyssop officinalis within 3 years of vegetation the most effective for the accumulation of essential oil can be identified three samples. In the first place is the sample number 1-1.2, which in 2015 showed an insignificant release of essential oil to 0.3 %, in 2016 – to 4,0 % and in 2017 – to 3.7 %. On the second place the sample under number 4-1.3. In 2015 it showed an output of up to 0.32 %, in 2016 – 3.8 % and in 2017 – 3.5 %. The third sample number 3-1.4 in 2015 contained essential oil was 0.23 %, in 2016 – 3.7 %, and in 2017 – 3.5 %. Of the fifteen samples of common oregano two samples with high content of essential oil are allocated. In the first place the sample numbered M-1.3 with the maximum content of essential oil in 2016 is 0.34 % and on the second place is number T-1.1 with the maintenance of an essential oil in 2016 0.31 %.
