To evaluate the introduced lentil varieties (Lens culinaris Medik.) originating from Canada and Spain in the conditions of the Southern part of the Forest-Steppe of Ukraine according to a complex of indicators of productivity and adap­tability. Methods. During 2019–2021, in the conditions of the plant research station Ustymivka Experimental Station of Plant Production of the Plant Production Institute of the NAAS of Ukraine (Poltava Region, 49o18’21”N, 33o13’56”E), 26 new samples of lentils from Canada and Spain were studied. In the pod and seed ripening stage (BBCH 86–90), under field and laboratory conditions, indicators of yield, productivity, 1000 seed weight, early-ripening, plant height and height from the soil of the first pod, number of pods and seeds per plant, number of seeds in a pod, pod parameters. Results. In the process of studying the new lentil samples, it was found that their productivity varied from 127 to 258 g/m2, with the most productive varieties being ‘CDC Creenstar’, ‘CDC Cherie’ (Canada), ‘Angela’, ‘Amaya’ (Spain). Throughout the study period, the highest productivity, according to the indicator “seed weight per plant”, was shown by the plants of the following lentil varieties: ‘CDC Cherie’ (4.4 g), ‘CDC Creenstar’ (4.2 g), ‘CDC Greenland’ (4.5 g), ‘CDC Imigreen’ (4.4 g), ‘CDC QG-2’ (4.1 g), ‘CDC Impulse’ (4.0 g) (Canada), ‘Angela’ (4.6 g) (Spain). Plant productivity was high, both in terms of increased number of seeds and 1000 seed weight. The highest level of the indicator of the number of pods per plant was recorded in the lentil varieties ‘CDC Imax’ (64.4 pcs), ‘CDC Impala’ (65.5 pcs), ‘CDC QG-2’ (67.4 pcs), ‘CDC Creenstar’ (67.8 pcs), ‘CDC Cherie’ (75.2 pcs) (Canada), ‘Amaya’ (64.8 pcs), ‘Angela’ (75.1 pcs) (Spain). Almost all the examined samples were of medium ripeness (81–85 days) and optimal for the Southern Forest Steppe Zone of Ukraine. The Canadian varieties ‘CDC QG-2’, ‘CDC SB-2’, ‘CDC Impulse’, ‘CDC Imvincible’, ‘CDC Impact’ were the earliest (76 days). Varieties combining several valuable characteristics deserve special attention: ‘CDC Creenstar’, ‘CDC Greenland’, ‘CDC Impulse’, ‘CDC Impact’ (Canada), ‘Angela’ (Spain). Conclusions. The above mentioned varieties can be recommended as sources of valuable traits for practical use in breeding, and they are also suitable for cultivation in the Southern Forest Steppe Zone of Ukraine.","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":"134933458","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}

To carry out an analysis of domestic and foreign scientific literature sources, information resources and the results of previous studies, based on which to evaluate the biological and ecological features and productive potential of plants Vigna genus and to determine their prospects for introduction in Ukraine.\u0000Methods. In the process of research, inventory information of NBG collection funds, catalogs of botanical gardens of Ukraine, directories, registers of varieties were used. Printed and electronic scientific periodicals and searchable scientific databases (Scopus, Web of Science, Pubmed, Researchgate, Research4Life, Science Direct, Google Scholar) were involved in the information search. The work used methods of introduction, analysis, systematization, comparison, and generalization of information data.\u0000Results. In the course of the screening of literary sources, it was found that the center of origin of plants of the genus Vigna is considered to be West Africa. Archaeological finds of these representatives date back to the IV millennium BC. Today, their natural and cultigenic ranges cover the Holarctic, Paleotropical, Neotropical and Australian realms. The genus Vig­na includes 105 species of plants, of which about 10 species are known in culture today, which are characterized by high heat, drought, acid and salt resistance, capable of providing high productivity of above-ground phytomass (3500–4500 kg/ha of absolutely dry matter) and productivity seeds (over 2000 kg/ha). Due to its rich biochemical composition (accumulates proteins, starch, vitamins, micro- and macroelements), it is actively used as a food, medicinal, fodder crop both in its homeland and almost all over the world.\u0000Conclusions. Thus, plants of species of the genus Vigna are promising potential crops of the 21st century.

To study of yield formation and protein content in the grain of different ripening varieties of soft winter wheat under the condition of using various types and doses of fertilizers.\u0000Methods. Field and laboratory (determination of protein content), calculation (collection of protein), mathematical and statistical.\u0000Results. It was found that different fertilization systems reliably increased the grain yield of soft winter wheat. The use of N75 increased this indicator by 1.2 times and N150 by 1.4 times in the varieties studied, compared with the no-fertilizer variant. Yield with incomplete return of phosphorus-potassium fertilizer was only 2–3% lower than with complete mineral fertilizer. With the nitrogen-phosphorus and nitrogen-potassium fertilization systems, the yield was 5–7% higher than with the nitrogen system. At the same time, this indicator was 6% lower than in the full mineral fertilizer version of the trial. The use of 75 kg/ha nitrogen fertilizer per year increased the protein content to 13.5%, or by 10% compared to the control. In the double dose nitrogen fertilizer variant, the protein content increased to 14.2% or by 15%. The use of nitrogen fertilizers with phosphorus-potassium only contributed 2–4% to the increase of this indicator. Cultivation of winter wheat under the condition of application of N75 increased the collection of protein up to 724 kg/ha or by 33%, and with a double dose of nitrogen fertilizer – up to 848 kg/ha or by 55% compared to the option without fertilizer. In the N75P30K40 variant, protein yield increased by 10% compared to the nitrogen system. The application of a complete mineral fertilizer (N150P60K40) increased this indicator by 12%.\u0000Conclusions. It was found that the use of N75P30K40 increased the grain yield of soft winter wheat by up to 5.9 t/ha, or 7%, compared to the option where only 75 kg/ha of nitrogen fertilizer was applied. Yield development in soft winter wheat varies considerably from variety to variety. For example, this indicator was 35% higher in the ‘KWS Emil’ variety than in the ‘Prino’ line. In addition, the grain yield of both varieties is reliably influenced by the weather conditions during the growing season. The protein content of soft winter wheat varies considerably depending on the variety and the weather conditions. When growing soft winter wheat varieties, the protein content can vary by 12.8–15.1%. Weather conditions during the growing season can change this indicator by 13.1–14.7%. The protein content index in the grain of the ‘Prino’ line is significantly higher than that of the ‘KWS Emil’ variety. According to the protein yield per hectare indicator, the ‘KWS Emil’ variety (896 kg/ha) has a significant advantage over the ‘Prino’ line (774 kg/ha).","PeriodicalId":53379,"journal":{"name":"Plant Varieties Studying and Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41247706","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}

To determine the biochemical indicators of seed quality of winter rape varieties grown under different conditions.\u0000Methods. During the research, the following methods were used: laboratory, calculation and statistical, to prepare conclusions – analysis and synthesis.\u0000Results. According to the results of laboratory studies, biochemical indicators of the quality of seeds of winter rape varieties, grown in different conditions, were established, namely: the content of oil, “crude protein” and glucosinolates. Meteorological conditions during the vegetation period of plants of the corresponding soil and climate zone have a significant influence on the quality indicators of seeds. Based on the results of the research, it was established that in 2022, compared to 2020, the biochemical indicators of winter rapeseed were higher. The increase in yield by 1.6 t/ha in the Steppe zone, 1.1 t/ha – Forest-Steppe, 1.4 t/ha – Polissia ensured an increase in oil content by 2.4% – Steppe, 6.6% – Forest-Steppe, 6.7% – Polissia and oil collection per hectare by 0.74 t/ha – Steppe and Polissia, 0.62 t/ha – Forest-Steppe. For the content of “crude protein”, a decrease in the index was observed, namely: by 3.1% in the Steppe zone, 5.8% in the Forest-Steppe and 5.0% in the Polissia in 2022 compared to 2020. Meteorological conditions of the research years in the corresponding soil and climatic zones had an influence on the content of glucosinolates. For the Steppe and Forest-Steppe zones, the indicators were identical and amounted to 0.7%, 0.8% (Polissia), while in 2021, for the Steppe and Polissia zones, the content of glucosinolates in rapeseed was 0.8% and 0.9% more, compared to the indicators obtained in other years of research.\u0000Conclusions. It was established that, on average, for 2020–2022, the total oil content in seeds of rape was 46.2% – Steppe, 47.5% – Forest-Steppe, 47.8% – Polissia; “crude protein” content – 19.6% – Steppe, 18.4% – Forest-Steppe, 17.9% – Polissia; the content of glucosinolates was 0.7% in the Steppe and Forest-steppe zones, 0.8% in the Polissia; oil collection in the Steppe zone 1.31 t/ha, Forest-Steppe – 1.16 t/ha, Polissia – 1.33 t/ha; protein collection per hectare is 0.54 t/ha in Steppe, 0.44 t/ha in Forest-Steppe and 0.48% in Polissia. Growing conditions over the years of research in the corresponding zone affect the formation of biochemical indicators of winter rapeseed.","PeriodicalId":53379,"journal":{"name":"Plant Varieties Studying and Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42377227","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}
