The research was conducted in accordance with the “Methodology of qualification examination of plant varieties for suitability for distribution in Ukraine (general part)” and “Methodology of examination of plant varieties of technical and forage group for suitability for distribution in Ukraine”. Results. New common sunflower varieties ‘LG50475’, ‘ОКLLАОМА’, ‘P64HЕ418’, ‘RGТ CHARLLОТТE CL’, ‘SY DIEGO CLP’, ‘F4987VО’, ‘N4H422 KL’, ‘LG50779 SХ’, ‘SUBЕО’ and ‘SY FЕNОМЕNО’, which are included in the State Register of Plant Varieties Suitable for Distribution in Ukraine, were analyzed for varietal potential in terms of economically valuable traits such as productivity, oleic acid and oil content.

It was found that the yield of winter triticale varieties in the Forest-Steppe and Polissia zones was 5.3 t/ha. The maximum yield in the Forest-Steppe zone was achieved by the variety ‘MIP Feniks’ (5.9 t/ha), in the Polissia zone by the variety ‘Pamiati Patseky’ (5.8 t/ha). It was found that the protein content of winter triticale varieties for the 2019–2020 research years in the Forest-Steppe zone was on average 12.6% and ranged from 12.2% (‘Liubomyr’) to 13.3% (‘MIP Yatahan’), which according to the classifier corresponded to grain of medium quality and can be used in the confectionery industry. The coefficient of variation (V,%) for this characteristic was 3.5%.

As a result of the study of five promising varieties of winter wheat, sown on September 25 and October 5 after two predecessors (soybean and sunflower), it was found that, regardless of the sowing dates, the average yield of the varieties studied was higher after the predecessor soybean and varied from 3.77 to 6.24 t/ha compared to its predecessor sunflower – 3.35–5.52 t/ha.

To determine the dependence of the intensity of callus formation and organogenesis of Linum usitatissimum L. convar. elongatum in vitro on explant type and variety in order to optimize the cultivation protocol. Methods. For induction of callus formation and organogenesis, hypocotyls, cotyledons, leaves, immature embryos and anthers of flax varieties ‘Hlinum’, ‘Esman’, ‘Hladiator’, ‘Hlobus’ and ‘Charivnyi’ grown on Murashige and Skoog medium were treated with 0.05 mg/l 1naphthylacetic acid and 1.0 mg/l 6benzylaminopurine at a photoperiod of 16 h, light intensity 2500 lux, relative humidity 60–80% and air temperature 22–24 °C. Empirical data were interpreted using arithmetic mean, error of the sample mean, coefficient of variation, least significant difference and rank order. Results. The intensity of callus formation and organogenesis in the analysed varieties depended on the object of study, i.e. the genotype of the variety and the type of explant. The frequency of callus formation ranged from 9.4 (anthers of variety ‘Esman’) to 99.4% (leaf explants of variety ‘Hlinum’), the weight of callus – from 0.18 (anthers of variety ‘Esman’) to 3.18 g (anthers of variety ‘Hlobus’), the frequency of organogenesis – from 7.4 (anthers of variety ‘Esman’) to 97.3% (hypocotyls of variety ‘Hlinum’), number of shoots – from 0.6 (anthers of variety ‘Hladiator’ and immature embryos of variety ‘Hlobus’) to 4.0 (hypocotyls of variety ‘Hlinum’), height of shoots – from 0.34 (anthers of variety ‘Esman’) to 1.63 cm (anthers of variety ‘Hlobus’). Conclusions. Plants of all the varieties studied are capable of effective callus formation and organogenesis in vitro in the presence of phytohormones of exogenous origin. Certain types of explants (hypocotyls, cotyledons, leaves) respond stably to exogenous growth regulators that induce callus formation, whereas others, such as anthers, have a specific response that is largely determined by cultivar characteristics. To obtain diploid somaclones, it is optimal to use hypocotyls of varieties ‘Hlinum’ and ‘Charivnyi’, to obtain haploid regenerants – immature embryos and anthers of varieties ‘Hlobus’ and ‘Hladiator’, which ensures the highest reproduction rate of cultural plant objects.","PeriodicalId":53379,"journal":{"name":"Plant Varieties Studying and Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136379438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laboratory, calculation and statistical methods were used during the research, analysis and synthesis methods were used to draw conclusions. \u0000Results. As a result of research, the dependence of spring barley quality indicators, namely: grain uniformity and protein content, on soil and climatic zones and growing conditions was revealed. Thus, grain uniformity ranged from 86.7% (high, Polissia) to 95.1% (very high, Forest Steppe) in the different test years. In 2021, thanks to favorable meteorological conditions during the growing season, its indicators increased by 4.3% in the Steppe, 4.6% in the Forest Steppe and almost 6.0% in Polissia compared to 2020. On average, the uniformity of grain grown in different branches of UIPVE increased by 5.6%.

The research involved laboratory, computational and statistical methods.\u0000Results. The highest oil content was obtained in 2019 in the Steppe zone in the seeds of such varieties as ‘ES COMPOSITOR’ (25.8%), ‘Churaivna’ (25.7%), ‘Atacama’ (25.7%) and ‘Acardia’ (25.3%); in Polish – ‘ES COMPOSITOR’ (24.7%) and ‘Acardia’ (24.2%).

To study the historical origins and stages of formation of the variety testing network of the Cherkasy Region, where one of the branches of the Ukrainian Institute for Plant Variety Examination is located. \u0000Methods. The Cherkasy branch of the Ukrainian Institute for Plant Variety Examination is located in the village of Dzenzelivka, Mankiv United Territorial Community, Uman district, Cherkasy Region. During the research, general scientific methods were used, in particular, hypotheses, observations, historical methods with elements of extrapolation of the source scientific database, analysis, as well as the method of synthesis to form conclusions. \u0000Results. The Cherkasy Region is a typical Ukrainian forest-steppe. Plant varieties common in the region meet the criteria of distinctness, uniformity and stability generally accepted in international practice; they meet the needs of consumers in terms of economically valuable characteristics; they do not pose a threat to the environment and human health. The Variety Testing Network of the Cherkasy Region was established in 1966 and its activities were coordinated by the Inspectorate of the State Commission for Variety Testing of Agricultural Crops in the Cherkasy Region. In 2002, the Cherkassy Regional State Centre for Expertise in Plant Varieties was established, which in 2012 became a branch of the Ukrainian Institute for Plant Variety Examination. \u0000Conclusions. The formation of varietal plant resources in the Cherkasy Region took place thanks to the rather long historical stages of formation and development of its varietal testing network.","PeriodicalId":53379,"journal":{"name":"Plant Varieties Studying and Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48879767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
