“…Сучасні сорти промислових конопель здатні формувати щорічно біля 12 т/га сухої біомаси [14], або 8,4 т/га целюлози, що є дієвим інструментом зі сталого управління лісовими насадженнями. Конопляна сировина в 1,4 рази має більшу масову часту целюлози, ніж деревина, та 3,5 рази менший вміст лігніну [15].…”

This article analyzes the potential for growing and processing of industrial hemp in accordance with the goals and objectives of sustainable development. Of the 17 sustainable development goals, they meet at least nine. Today it is a niche crop grown by small agricultural enterprises, and the organization on their basis of simple value chains for processing seeds and stems allows to diversify crop production, create new jobs and appropriate economic development of rural areas. The total costs for growing and processing hemp raw materials from 100 hectares of crops directly in the agricultural enterprise amount to UAH 5,7 million, and the income from the products produced by a simple value chain will amount to UAH 12,9 million. Industrial hemp seeds and products made from it are a valuable source of omega-3 and omega-6 polyunsaturated fatty acids in the optimal combination, so they serve as a basis for the development of the food industry for both regional and international markets. It is appropriate to involve the high nutritional potential of hemp seeds in the organization of a balanced diet, including children of different ages. The cannabinoid system of industrial hemp has a therapeutic and prophylactic effect on the human body, so the world community is actively involved in the raw materials of industrial hemp in the manufacture of biologically active additives and drugs. The development of this area in Ukraine requires appropriate changes in legislation. A hectare of industrial hemp is capable of forming more than 12 tons of dry biomass, containing up to 80 % of cellulose suitable for the production of various types of paper. The use of hemp in this direction contributes to the preservation of forests and is an effective measure to combat climate change and its consequences. Hemp is a traditional agricultural crop in Ukraine, the cultivation of which contributes to the conservation of biodiversity and agrobiocenoses. Their cultivation has a minimal environmental impact on the environment, and the processing of raw materials is characterized by waste-free production.

“…THC-free cultivars of industrial hemp have opened the prospects for a transition to a new level of increasing the cultivars" performance in terms of oil and fiber contents as well as of seed and stem yields. New hemp cultivars, Hlesiia, Mykolaichyk, Hlukhivski 51, and Hlukhivski 85, are noticeable for these unique biological features [6][7][8][9].…”

Purpose and objectives. To reveal new possibilities for the expression of cannabis genotypes to obtain starting material with increased contents of non-psychotropic cannabinoids, without tetrahydrocannabinol and stabilized biological traits. Material and methods. In our study, we took Ukrainian hemp cultivars, the populations of which were distinguished by high stability of cannabinoid contents in comparison with foreign cultivars, as a basis. The study was carried out using breeding, biochemical and statistical methods: physical mutagenesis, inbreeding, individual selection, thin-layer and gas-liquid chromatography to evaluate plants for cannabinoids (HP 6890 Series Hewlett Packard chromatograph using an internal standard). Results and discussion. It was found that gamma rays at a dose of 200 Gy disrupted the genotypic relationships between cannabinoids, with accumulation of their minimum or maximum amounts. Lowering the irradiation dose to 150 Gy does not destabilize the population in terms of the cannabinoid contents. Inbreeding can be also used in breeding for both to create inbred lines that are homozygous for the ‘no cannabinoids’ trait and to identify lines with increased contents of cannabidiol, cannabigerol or cannabichromen. A lot of early-bred and modern cultivars (French, Polish, Hungarian, German) show a high population variability of the cannabinoid contents, proving that no systemic breeding was conducted to stabilize these traits in the populations of these cultivars. High homogeneity of populations in terms of the formation and accumulation of cannabinoids is only intrinsic to monoecious hemp cultivars bred by the Institute of Bast Crops of NAAS. The homozygosity of a population primarily depends on the control of targeted cross-pollination between cannabinoid-free plants using an express testing plants for these compounds prior to anthesis onset and subsequent analysis of the selected elite plants by thin-layer chromatography. Given the relevance of creating hemp varieties with therapeutic properties, breeding methods have been developed to shift the balance of ‘no cannabinoid at all’ towards a genetically determined increase in one of the cannabinoids (cannabidiol, cannabigerol, cannabichromene) combined with eliminated psychotropic activity (the THC content does not exceed 0.08%). Studies of cannabinoid accumulation revealed differences in their formation during the growing period. Based on the fact that the maximum accumulation of cannabinoids occurs during the seed ripening onset, and, in particular, their synthesis is the most intensive in perianths and small leaves, it is possible to evaluate the prospects for creating hemp cultivars with a branched diamond-shaped inflorescence, which will provide, in addition to a high content of one or another cannabinoid, an increased yield of plant biomass. Conclusions. Physical mutagenesis, inbreeding and selection are promising breeding methods for reducing psychotropic tetrahydrocannabinol, stabilizing cannabis cultivars in terms of the absence of cannabinoids, increasing the contents of cannabidiol, cannabigerol and cannabichromene gaining advantage from valuable collection accessions
