Hemp (Cannabis sativa L.) is currently one of the most controversial and promising crops. This study compared nine wild hemp (C. sativa spp. spontanea V.) accessions with 13 registered cultivars, eight breeding lines, and one cannabidiol (CBD) hemp strain belonging to C. sativa L. The first three groups had similar main essential oil (EO) constituents, but in different concentrations; the CBD hemp had a different EO profile. The concentration of the four major constituents in the industrial hemp lines and wild hemp accessions varied as follows: β-caryophyllene 11–22% and 15.4–29.6%; α-humulene 4.4–7.6% and 5.3–11.9%; caryophyllene oxide 8.6–13.7% and 0.2–31.2%; and humulene epoxide 2, 2.3–5.6% and 1.2–9.5%, respectively. The concentration of CBD in the EO of wild hemp varied from 6.9 to 52.4% of the total oil while CBD in the EO of the registered cultivars varied from 7.1 to 25%; CBD in the EO of the breeding lines and in the CBD strain varied from 6.4 to 25% and 7.4 to 8.8%, respectively. The concentrations of δ9-tetrahydrocannabinol (THC) in the EO of the three groups of hemp were significantly different, with the highest concentration being 3.5%. The EO of wild hemp had greater antimicrobial activity compared with the EO of registered cultivars. This is the first report to show that significant amounts of CBD could be accumulated in the EO of wild and registered cultivars of hemp following hydro-distillation. The amount of CBD in the EO can be greater than that in the EO of the USA strain used for commercial production of CBD. Furthermore, this is among the first reports that show greater antimicrobial activity of the EO of wild hemp vs. the EO of registered cultivars. The results suggest that wild hemp may offer an excellent opportunity for future breeding and the selection of cultivars with a desirable composition of the EO and possibly CBD-rich EO production.

The aim of this study was to estimate the correlations among agronomic, physiological and phytochemical traits of two varieties of Artemisia annua and to identify correlations that can be used in selection and breeding processes for this species. The design was completely randomized and the treatments were for Artemisia annua varieties 2/39x5x3M and 2/39x1V, which were subjected to agronomic, physiological and phytochemical evaluations. The relationship among the studied traits was estimated with Pearson's correlation coefficient, and the significance level of correlations was established by the t-test using Genes software. A significant positive correlation was found between the traits canopy volume and essential oil yield for 2/39x5x3M variety, showing that the selection of plants with a larger canopy volume would facilitate indirect selection of the trait essential oil yield. This correlation was not found for the 2/39x1V variety. In both varieties, there was a significant negative correlation between canopy volume and artemisinin content, which suggested that the selection of plants with a large canopy volume and a large number of branches should be avoided if the goal is to increase artemisinin content.

Coriander is a multi-purpose essential oil plant that has various growing purposes: to obtain essential and fatty oils, to use it as a spice and a green herb. Coriander is a leader in the production and consumption of essential oils. The largest cultivation region in Russia is the Central Blackearth Region. The current work has shown the possibility to grow coriander in the conditions of the Rostov region and has revealed the best genotypes adapted to insufficient humidity. There have been studied 124 coriander collection samples according to various economically valuable traits. There has been presented a range of their variation by the growing season duration from 84 to 106 days, by the plant height from 42 to 80 cm, by yields from 26.5 to 250 g m2, by essential oil percentage from 0.56 to 2.15%, by oil content from 18.9 to 25.4%, by oil yields from 21.4 to 56.5 g/m2, by 1000-kernel weight from 5.2 g to 7.4 g. The paper also shows the conditions to form their greatest values. There have been identified the samples “K-298”, “K-259”, “K-284”, “K-272”, “K-179” with the most valuable set of economic features that can be revealed under various conditions. There have been selected the coriander samples “K-428”, “K-298”, “K-284”, “K-272”, showing high seed yields under free flowering and under isolators. There has been established a fruit formation coefficient (0.16–0.45) taking into account free flowering and insulators, and there have been selected the samples showing a lesser degree of oppression under insulators (with a fruit formation coefficient of >0.3).

The main receptacle of essential oil in true lavender is the peltate glandular trichomes of the calyxes in the whorls of the inflorescences. Their average size is 175 ± 25 µm, in some cases – up to 250 µm. For the extraction of lavender oil, not only the calyxes are used, but the whole inflorescences including the flowering shoots. The surface of the peduncles of lavender inflorescences is also covered with peltate glandular trichomes. However, their contribution to the total volume of essential oil in the inflorescence has almost never been determined. The aim of this research was to study the distribution density of glandular trichomes within the inflorescence and to determine the proportion of the contribution of flowering trichomes to the formation of essential oil in the inflorescence. The research was carried out in 2021 on the basis of the V.S. Pustovoit All-Russian Research Institute of Oil Crops in two ecological and geographical points of the Krasnodar region. The object of the study was the true lavender varieties Voznesenskaya 34, Rannyaya, Yuzhanka and Voznesenskaya Aroma. It was found that the size of glandular trichomes on peduncles of true lavender is 90 ± 15 µm. Their number on peduncles, depending on the variety, varies from 2141 to 3003 pcs. The density of distribution of glandular trichomes on the surface of peduncles is equal to 8.60–14.93 pcs/mm3 . The total volume of essential oil in all glandular trichomes of peduncles is 0.41–0.57 cmm . The total volume of essential oil in the inflorescences varied from 2.28 to 5.15 cmm . The share of essential oil in the glandular trichomes of the peduncles in relation to the entire inflorescence ranged from 9.33 to 19.56%. It is concluded that peltate glandular trichomes on flower-bearing axes make a significant contribution to the essential oil content of lavender inflorescences. For the selection of true lavender to increase the essential oil content and the yield of essential oil, an additional selection trait is proposed – the amount of glandular trichomes on the surface of peduncles, which can be regulated by changing their distribution density on the surface of peduncles, or increasing the length of inflorescences.

Spike lavender, Lavandula latifolia Medik., is a species of economic importance for its essential oil (EO). The purpose of this study was to estimate the effect of the variable climate and fixed factors such as soil and geographic location on EO yield and quality. The study material was collected in 34 populations from four different Spanish bioregions for three years. The EO extraction from spike lavender leaves and flowers was done with simple hydrodistillation, in Clevenger. Soil samples were also collected. Climate data were provided by the State Meteorological Agency. The EO average yield was obtained for the bioregion mean and in each bioregion. The higher EO yield is related clearly to the climate condition. A greater amount of annual rainfall produced a higher EO yield in the four bioregions and of better quality. Soils richer in organic matter and minerals produced higher EO yield but with less quality. The altitude had little effect on EO yield. Higher altitude favored obtaining higher EO quality. At lower latitude, further south, the populations obtained a higher EO yield. The evaluation of the environmental effect on the EO yield and quality could allow better natural conservation and more accurate selection of the best populations for breeding and spike lavender cultivation protocols.

In article questions of selection of mint – a valuable aromatic plant in our country are considered. Using wild-growing types of mints as donors of the economic and useful signs and also various methods of selection – clonal selection, hybridization, a mutagenesis by selectors are created the high-yield, steady against biotic and abiotic factors of the external environment, adapted to cultivation to concrete soil climatic conditions grades of mint of different purpose. Their comparative sortoispytaniye in the conditions of the Nonchernozem zone of the Russian Federation showed that on set of economic and valuable signs Medichka  grades, Lekarstvennaya 4, Yantarnaya and Aromatnaya, possessing a good bouquet and aroma of an essential oil which are the most perspective for cultivation on a mint leaf, whereas grades the Moskvichka and Kubanskaya 6 with the increased content of menthol in oil more are suitable for production of an essential oil and mentholum were allocated. The profitability level of peppermint production due to the peculiarities of the varieties, their yield, resistance to abiotic and biotic factors, and the high costs of manual labor during planting, depends on the region of cultivation. In most cases, this is due to the shortcomings of the existing assortment of this crop in a given zone. A set of varieties is needed that can use the favorable environmental factors (natural and anthropogenic) with the greatest efficiency and stand against stress factors simultaneously. The further selection work with mint directed to increase in content biologically of the active materials in a feed stock, has to be conducted with use of methods of genomic selection.
