“…Hemp (Cannabis sativa) is an herbaceous plant that is currently receiving increased attention from researchers and policymakers owing to its industrial use (in production of textiles, biofuel, and bioplastics) and medicinal properties. This triggers an urgent need to produce varieties that are suited to the requirements of emerging developments in the use of hemp by the concerned industries [1]. Research systems should therefore complement and support growers to ensure sustainability in hemp cropping schemes that are currently threatened by the adverse effects of climatic variabilities and the COVID-19 pandemic.…”

The elevated research interest and increased cultivation of Hemp (Cannabis sativa) across the globe is significantly driven by its multidirectional industrial uses and medicinal properties. Scientific research publications focusing on hemp breeding plays a pivotal role in bridging the knowledge gap and opening new avenues for upscaling the efficiency of crop improvement initiatives. The identification of prevailing research trends and associations is critical in defining and mapping the trajectories of success in Hemp breeding. The advent of bibliometrics and scientometrics is currently providing a stead platform which fosters effective identification of current research patterns and examination of the applied methodologies, focus areas, and operational constraints. In the context of Hemp research, content assessments provide breeding initiatives with background data needed for exploring various traits of interest and for validating investments and related policies. The main thrust of this study is to perform a bibliometric and scientometric analysis of Scopus-indexed papers covering the field of ‘Hemp Breeding’, between calendar years 1908 and 2020. Data was analyzed using VOSviewer (Version 1.6.16) and Microsoft Excel (2019). The study found 152 papers composed of original articles (105, 69.08%), book chapters (23, 15.13%), conference papers (10, 6.58%), reviews (9, 5.92%), conference reviews (3, 1.97%) and books (2, 1.32%). A significant increment in research publications was observed after 1950. The assessment also indicated that most of the archived research was conducted or reported in the USA (13.82%), Italy (12.5%) and the Netherlands (11.18%). Furthermore, the highest number of papers over the studied period and topic were published by authors affiliated to Wageningen University & Research (16, 10.53%). Index keywords such as Cannabis sativa, hemp, genetic expression, genetic marker, and genetic diversity were covered extensively in the sampled journal editions. A comparative assessment of the results indicated that there is need to scale-up research initiatives targeting hemp trait improvements to cater for the projected high demand and climate change. This can be achieved through strengthening synergistic partnerships and knowledge exchanges across the hemp breeding value chain. This research will assist plant breeders in defining research requirements, determining evidence-based scientific gaps, and recognizing outstanding research institutions for potential intellectual sharing and cooperation.

“…Other scientists underlined that even 500 mm of rain, dropped out during the vegetation period, is not enough for cannabis. Most of water is consumed in the period from bud formation till the end of flowering (50-70 % of total growing season precipitation) [7][8][9].…”

Abstract. In the development of economical and convenient renewable energy fuel in the last years, pelleting of biomass has become the most used technology for biomass processing. Fibrous plants were chosen for biofuel production -fibrous hemp (Cannabis sativa L.) and fibrous nettle (Urtica dioica L.) -for their high productivity and soil undemanding. Three sorts of fibrous hemp were chosen: Felina 32, USO 31, Finola and one sort of fibrous nettle. Laboratory trials with plant preparation and usage for energy purposes were carried out in the Aleksandras Stulginskis University and Lithuanian Energy Institute. Biometric features of plant stems were determined, and, later, the plants were chopped, milled and granulated into pellets of 6 mm diameter. For chaff milling a hummer mill Retsch SM 200 was used, and the mill fractional composition was determined. Mill was granulated by a small capacity granulator with a horizontal matrix. The pellet quality indicators -moisture content, density, and strength and heat value were determined. The fibre plant pellet moisture content ranged from 7.3 % to 10.0 % and pellet density reached 899.3 -1221.6 kg·m -3 DM (dry matter).

“…У світовій практиці сформувались наступні мета і основні завдання сучасної селекції конопель: підвищення урожайності волокна і його якості, контроль за ознаками однодомності і вмісту канабіноїдів, стабілізація тривалості вегетаційного періоду і створення стійкого до шкідників і хвороб вихідного матеріалу [1]. Водночас використовують як класичні (масовий та індивідуальний добір, кросбридинг, інбридинг і гібридизацію) [2] й біотехнологічні [2,3] методи селекції, так і молекулярні технології (використання генетичних маркерів для маркування селекційних ознак), однак розроблення останніх ще розвивається і знаходиться на початкових етапах впровадження [1,[4][5][6][7][8][9].…”

Inbreeding and its extreme form (self-pollination) are an effective method for stabilizing the monoecious traits of industrial hemp. The hybrids with self-pollinated lines as the components of which, in most cases, were characterized by a better sex composition than the output cultivar forms, and the absence of male plants. The number of monoecious feminized plant (the main sexual type of modern varieties) in hybrids created as a result of crossing in the directions of vertical convergence was from 54.2 to 100.0 %, and in hybrids created by crossing in horizontal convergence it was from 37.7 to 100.0 %. The use of hybridization in the directions of vertical and horizontal convergence is advisable in the breeding of industrial hemp, especially for obtaining a starting material with a stable trait of monoecious, with high plant biomass, fber content and seed productivity. We recommend the following crosses: the frst and third generations of simple linear-varietal hybrids of various ecological-geographical types, related to one of the parental forms (F1 × F3) (i); crossing of simple interlinear hybrids of various ecological-geographical types with an inbred line of the Central European type of a later generation from self-pollination (interline hybrid × self-pollinated line) (ii); reciprocal crosses of simple interlinear hybrids of various ecological-geographical types with the original cultivar of a self-pollinated line of the middle European type (interline hybrid × cultivar and cultivar × interline hybrid) (iii); crossing of simple linear-varietal and intervarietal hybrids of the frst generation, related in one of the parental forms (iiii). The consistent use of crossbreeding, inbreeding (or divergence), hybridization (or crossing in the vertical and horizontal convergence directions) has created heterotic hemp forms with stable productive potential, homogeneous sex structure, and non-psychotropic properties. The created variety ‘Aurora’ is an example of an innovative breeding method. Key words: hemp, breeding, sex, monoecious, crossbreeding, inbreeding, divergence, convergence, hybrid, productivity.
