Determination of the elemental composition of plant material was carried out by the X-ray fluorescence method.\u0000Results. The content of mineral elements in plants depends on their individual ability to absorb elements from the soil and accumulate them in the roots, leaves and flowers. Plant samples of three species of wormwood were grown and studied during the flowering phase under conditions of introduction in M. M. Gryshko National Botanical Garden of National Academy of Sciences of Ukraine (NBG) during 2019–2022. The qualitative and quantitative content of different macro- and microelements in the soil and plants were investigated. It was shown that aerial parts of the investigated plants accumulate the most important elements for the plants life, such as – K, Fe, Cu, Zn and Mn. Mesoelements Ca and S are present in sufficient quantities also. Elements Nb, Y, Ti, V, Cr were detected in soil, but were not determined in plants. Only A. annua plants contains Ni and Se, while A. ludoviciana and A. annua plants contain Pb. The amount of toxic elements in plants did not exceed the maximum permissible concentrations for vegetable raw materials and food products.\u0000Conclusion. Content of the main macro- and microelements was determined in the plants A. annua, A. ludoviciana and A. austriaca growing in NBG. The tendency of plants A. ludoviciana to accumulate high concentrations of iron in the roots and aerial part was observed. The obtained data will be useful for forecasting and evaluating the results of introduction of new promising species of the genus Artemisia, in breeding of new varieties of wormwood, to determine their pharmacological properties and to make a decision about the feasibility of using them in herbal tea and food products.","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":"43392616","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}

The influence of the growing zone, the growing season conditions and the genotype of the soft winter wheat varieties on yield, protein and gluten content were determined. The conditions of the growing zone have the greatest influence on studied varieties yield – 73%. On average, for 2020–2021, the maximum yield was obtained in the Forest-Steppe zone – 6.23–8.39 t/ha. In the Forest zone, the yield of studied soft winter wheat varieties was 5.31–7.02 t/ha. For the Steppe zone, the yield was within 5.16–6.63 t/ha. It was determined that varieties which showed low yield in the Forrest zone were characterized by higher yield in the Steppe zone. It was found that the growing zone (49%) and growing season (42%) conditions have the greatest effect on the protein content in grain of studied varieties. It was determined that variety ‘MANDARIN’ was characterized by the highest protein content in all growing zones (14.5–16.4%). In the Steppe and Forest-Steppe zones, high protein content was identified in grain of wheat varieties ‘Tata Mata’ (13.6–14.3%), ‘Eneida’ (13.6–14.3%) and ‘Novator’ (14.2 and 13.2%), in the Forest zone – in grain of varieties ‘Vahoma’ and ‘Eneida’ – 13.4% each. It was found that the growing zone conditions impacted gluten content in grain of studied wheat varieties by 64%, the influence of the growing season conditions was 28%. The effect of variety genotype on protein and gluten content was 5 and 4%, respectively. The grain of soft winter wheat varieties ‘MANDARIN’ and ‘Eneida’ contained the largest amount of gluten in all growing zones (27.7–31.8% and 27.3–30.3%). For the Steppe and Forest-Steppe zones, a high gluten content was found in grains of varieties ‘Illusion’ (28.4 and 30.8%) and ‘Tata Mata’ (27.8 and 29.8%).\u0000Conclusions. It was found that growing zone conditions of soft winter wheat varieties (73%) and the interaction of factors zone × year (21%) impacted the yield significantly.

Winter garlic is a heterogeneous biological material, and due to the complex of its diverse morphological and economically valuable features (in nature and culture), it is possible to select promising forms. Crop productivity is determined by climatic variables such as temperature and precipitation (the main abiotic environmental factors). Given the current trends in climate change, it is important to carry out analyzes aimed at describing and selecting plant genotypes with the best adaptive and productive properties. The investigation is focused on studying the adaptive and productive potential of promising samples of Allium sativum L. subsp. sagittatum together with the varieties on which the production of garlic in Ukraine is based, according to such characteristics as “bulb mass”, “yield” and “essential oil content”.\u0000Methods. During 2020–2022, in field conditions (Uman, 48°46¢N, 30°14¢E), five common and two newly created (‘Apollon’ and ‘Dzhovanna’) varieties of winter garlic were studied, as well as its promising variety samples No. 25 and 40. The obtained results were evaluated by the method of regression analysis to determine the stability and plasticity of the varieties.\u0000Results were conditionally divided into two groups according to parameters. The first group contained results that show the most important adaptive and productive characteristics (bulb mass, yield, plasticity, stability, selection value, adaptability). The second one included the parameters of the biochemical properties of the studied populations (essential oil), which in this case demonstrated significant influence and substantial stability. Most of the researched garlic populations are able to serve as effective material for obtaining new varieties. They can be classified as follows: ‘Khando’, ‘Dzhovanna’, ‘Apollon’, No. 25 and No. 40 – high yield, adaptability and breeding value; ‘Sofiivskyi’, ‘Apollon’ and No. 40 – technological quality (technical varieties); ‘Giovanna’ – food quality (table variety).\u0000Conclusions.

To justify the use of the Lewis phenotypic stabi­lity factor (SF) to determine the stability of the manifestation of quantitative and economic value characteristics of national varieties of sweet potato (Ipomoea batatas L.).\u0000Methods. Field research on the comprehensive assessment of new sweet potato varieties was carried out in 2021–2022 at the Institute of Vegetable and Melon of the NAAS (Kharkiv Region). Phenological observations and biometric measurements of plants were carried out, as well as recording of meteorological data during the growing season, in particular during interphase periods of the culture. The stability of the studied traits was determined by finding the limit values of their manifestation (Xmax and Xmin) and further calculating the Levis phenotypic stability factor (SF).\u0000Results. The use of the Levis phenotypic stability factor (SF) made it possible to determine the stability of the manifestation of morphological features of sweet potato varieties (I. batatas), in particular, the quantitative characteristics of tubers: their number under the bush for the variety ‘Admiral’ is 5.3 pcs., for ‘Slobozhanskyi rubin’ – 3.7 pcs.; the average weight of the tuber is 254 and 283 g, respectively. The trait “sweet potato tuber shape index” ensured stability with a coefficient of 0.98 (‘Admiral’) and 1.03 (‘Slobozhanskyi rubin’). The stability of the manifestation of morphological features of sweet potato tubers was established for the varieties ‘Admiral’ and ‘Slobozhanskyi rubin’, which are common in Ukraine. They represent two maturity groups, and therefore differ in the duration of the tuber formation period. Thus, the early-ripening ‘Admiral’ has a vegetation period of 100–110 days; medium-ripening ‘Slobozhanskyi rubin’ – 110–120 days.\u0000Conclusions. The quantitative trait of sweet potato tubers of the ‘Admiral’ variety was more stable in terms of width; ‘Slobozhanskyi rubin’ variety – in terms length. Tuber length values varied within cultivars. The shape index of sweet potato tubers as an identification feature of varieties turned out to be variably unstable; the calculated Lewis phenotypic stability factor was lower than unity for both studied varieties.","PeriodicalId":53379,"journal":{"name":"Plant Varieties Studying and Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44503625","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 peculiarities of the manifestation of combining ability and the mode of inheritance of yield-related traits in winter barley and to identify genetic sources and promising hybrid combinations for further breeding efforts under conditions of Ukrainian Forest-steppe. \u0000Methods. The research was conducted in 2018/19 and 2021/22 at the V. M. Remeslo Myronivka Institute of Wheat of NAAS of Ukraine. In accordance with generally accepted methods, the degree of phenotypic dominance, heterobeltiosis and effects of general combining ability in the top-cross hybrids of winter barley for key yield components were determined. \u0000Results. The variability of the manifestation level of the studied traits in parental components and hybrids in different years were established. According to the indicator of the degree of phenotypic dominance, the variability of the character of inheritance was revealed depending on the traits, hybrid combinations and growing conditions. Hybrid combinations with positive overdominance and dominance of individual yield components were highlighted. In particular, according to plant productivity these combination are: ‘Scarpia’ / ‘MIP Darii’, ‘Scarpia’ / ‘MIP Korsar’, ‘Aborygen’ / ‘MIP Corsar’, ‘Titus’ / ‘MIP Status’, ‘MIP Yanus’ / ‘MIP Status’, ‘Titus’ / ‘Paladin Myronivskyi’, ‘Maybrit’ / ‘Paladin Myronivskyi’ ‘MIP Yanus’ / ‘Paladin Myronivskyi’. The varieties with increased effects of general combining ability for yield-related traits under different growing conditions were distinguished. As follows: productive tillering – ‘Scarpia’, ‘MIP Darii’; grain number per ear – ‘MIP Yanus’, ‘MIP Hladiator’, ‘MIP Status’; 1000 grain weight – ‘Titus’, ‘MIP Korsar’, ‘MIP Status’; grain weight per plant – ‘MIP Yanus’, ‘MIP Status’, ‘MIP Darii’. \u0000Conclusions.

The studies were carried out during 2018–2020, on the basis of the V. M. Remeslo Myronivka Institute of Wheat NAAS of Ukraine. When considering the results obtained, generally accepted methods of genetic and statistical analysis were used.\u0000Results. Evaluation of breeding material in different years makes it possible to obtain information about the characteristics of the reaction of genotypes to changes in environmental conditions. As a result of the studies, it was found that the lines Lutescens 14-32 (bi = 0.59), Erythrospermum 15-32 (bi = 0.44), Lutescens 14-47 (bi = 0.22) were of high plasticity. Calculations of ecological stability indicate that lines are considered stable, the variance of stability is zero or close to zero. From a practical point of view, lines with a combined manifestation of high ecological plasticity and stability are considered valuable. This was the line Erythro­spermum 15-32 (bi = 0.44; S2di = 0.01) that indicates its low reaction rate and the ability to provide a consistently high level of yield under any growing conditions. The most valuable are the genotypes that combine a low level of the coefficient of variation, high homeostaticity and bree­ding value, which include the lines Erythrospermum 15-32 (Hom = 206.42, Sc = 4.11), Lutescens 14-47 (Hom = 98.41, Sc = 3.91), Erythrospermum 17-08 (Hom = 78.57, Sc = 3.76), Erythrospermum 14-65 (Hom = 54.84, Sc = 3.75), Lutescens 14-32 (Hom = 54.60, Sc = 4.17), Lutescens 14-13 (Hom = 35.60, Sc = 3.78), Lutescens 14-48 (Hom = 46.66, Sc = 3.58).\u0000Conclusions.

Analysis of plant micropropagation technologies for the creation of viable interspecific hybrids and varieties of Actinidia Lindl. \u0000Methods. General scientific – hypothesis, experiment, observation, analysis, synthesis method for drawing conclusions. \u0000Results. The introduction of in vitro technologies is now becoming the dominant commercial method of large-scale and rapid production of seedlings with stable inheritance of variety traits, high multiplication rate, preservation of economically valuable traits in the absence of production seasonality and time constraints. In addition to reproduction, the breeding process is also accelerated, including mutagenesis and hybridization. It is important to obtain not only a sterile explant, but also a morphogenically active one, that is, a plant that takes roots and subsequently regenerates in vitro. The best in terms of decontamination efficiency is the method of treatment with hypochlorite and the addition of PPM biocide to the nutrient medium, but under these conditions, the lowest survival of explants in all samples was noted. The efficiency of introduction into aseptic culture at the first stage of micropropagation is also affected by the biological characteristics of the primary explants. In studies with nutrient media for A. arguta, it was found that of the elements of mineral nutrition, only 11 ions are necessary for life: five macro- (N, K, P, Mg, S) and six microelements (Cl, Fe, B, Mo, Na, I). Plants in vitro have a lower dry matter content and a greater amount of moisture, including free moisture, which is quickly lost when the water balance is disturbed. \u0000Conclusions. The abi­lity to regenerate is more pronounced in the species A. chinensis and A. deliciosa, and to a lesser extent in A. arguta.

The study was carried out at the M. Remeslo Myronivka Institute of Wheat of National Academy of Agrarian Sciences of Ukraine in 2019 and 2020. In F1 of spring barley in two diallel crossing schemes the degree of phenotypic dominance, parameters of genetic variation, and combining ability for kernel number per spike were determined. Results. According to the indicator of the degree of phenotypic dominance, all possible types of inheritance of kernel number per spike were identified. In a number of crossing compositions, a change in the type of inheritance depending on the conditions of the year was revealed. Most combinations with overdominance in both years were noted in crossings of the covered awned cultivar ‘Avgur’, as well as the covered awnless cultivar ‘Kozyr’. According to the parameters of genetic variation in crosses of malting varieties (covered awned), correspondence of the additive-dominant model, overdominance and dominance in loci, as well as unidirectional dominance to increasing of the trait caused by dominant effects were revealed. When crossing cultivars of different varieties, a change in gene action in different years was found. In particular, additive-dominant system changed to complementary epistasis, incomplete dominance to overdominance, unidirectional dominance to increa­sing of the trait to multidirectional dominance. The genetic sources of increased general combining ability were identified, as follows: covered awned malting cultivars ‘Quench’ and ‘Avgur’, the naked awned cultivar ‘CDC Rattan’, as well as the covered awnless cultivar ‘Kozyr’.

To determine the influence of the moistening conditions and treatment of seeds with biological preparations Azotofit-r, Fitotsyd, Mycofriend-r, Orhanik-balans Monofosfor on growth processes at the initial plant life stages, formation of stand density and grain yield of winter wheat varieties.\u0000Methods. General scientific, special, field, mathematical-statistical and calculation-comparative methods were used for research.\u0000Results. The key to a high yield of winter wheat is in obtaining even stands, forming the optimal density of plant stands at the time of harvesting, taking into account their survival rates, the coefficient of productive tillering, and the study of new varieties adapted to climate changes. According to the research results, it was determined that, on average, for 2020–2022, the highest grain yield among the studied varieties of winter wheat was recorded in plants of the variety ‘Duma Odeska’ (8.38 t/ha) under irrigation in the variant with pre-sowing treatment of seeds with the biopreparation Azotofit-r, which was 0.78 t/ha more compared to the control (treatment with water). In the variant without irrigation, the yield was 6.08 t/ha, which was less than the control by 2.3 t/ha or 27.4%.\u0000Conclusions. The developed elements of the technology of winter wheat varieties growing make it possible to form the optimal plant density and significantly increase grain yield in the conditions of the Southern Steppe of Ukraine","PeriodicalId":53379,"journal":{"name":"Plant Varieties Studying and Protection","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46000586","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}
