Barley Resistance

The nature of the inheritance of resistance to Erysiphe graminis f. sp. hordei in the crosses of genotypes of spring barley in F1 and transgressive variability in F2 populations are investigated. Inheritance of the trait of resistance to Erysiphe graminis f. sp. hordei in F1, by hybridization of genotypes of spring barley with known genes of resistance to Erysiphe graminis f. sp. hordei in European varieties Eunova (mlo11) and Barke (mlo9), which are located on chromosome 1H, was positively dominated. Inheritance of the F1 trait in Aspen (mlo11) and Adonis (mlo9) cultivars was partially positive. The influence of parental pairs for hybridization on the indicators of the degree of phenotypic dominance, hypothetical and true heterosis was established. Resistance to Erysiphe graminis f. sp. hordei in F1 hybrids was observed heterosis (positive dominance) in fve hybrid combinations (hp = 1.1–1.9 %): Barke/Badoryi, Barke/Sanktrum, Parnas/Rostentsii, Badoryi/ Barke, Eunova/Zvershennia. Hypothetical heterosis (Ht) in F1 was observed in 13 of 16 hybrids (from +2.8 % to +97.6 %). A positive value of true heterosis (Htb) in F1 was observed in 15 hybrids out of 16 (from +1.9 % to +98.8 %). Inheritance of the trait of resistance to Erysiphe graminis f. sp. hordei in all studied hybrids was influenced by the cytoplasm of the mother plant, except for the hybrid Eunova / Triangel, where the influence of the nuclear apparatus was detected. Hybrids were found in the F 2 population with high resistance to Erysiphe graminis f. sp. hordei, which exceeded the parental components, which indicates a signifcant shaping process and the possibility of selection on the basis of the studied trait. The degree of positive transgression ranged from 16.0 % to 73.0 % in hybrids Aspen / Skarlet, Adonis / Vanja, Barke / Badoryi, Barke / Sanktrum, Eunova / Triangel and Eunova / Zvershennia, where highly resistant varieties were used for the mother form. The combinations in which the frequency of transgression was observed in more than 50.0 % of plants are hybrids: Eunova / Triangel, Barke / Sanktrum, Eunova / Zvershennia, Parnas / Rostentsii and Barke / Badoryi. Key words: spring barley, resistance, Erysiphe graminis f. sp. hordei, combinations of crossing, inheritance, F1, true and hypothetical heterosis, degree of phenotypic dominance, F 2, degree and frequency of transgressions.

The influence of long-term application of different doses and ratios of mineral fertilizers in field crop rotation on the content of basic nutrients in grain and straw of spring barley has been established. The study was held in the conditions of podzolic black heavy loam soil of the Right-Bank Forest-Steppe of Ukraine. The relative nutrients removal by spring barley depending on the doses of different types of fertilizers and their combinations in the field crop rotation is calculated. It is shown that the content of basic nutrients in the harvest of spring barley (grain and straw) significantly depends on the content of their mobile compounds in the soil. This is especially true of nitrogen and less of potassium. Economic removal of nutrients from the grain harvest of spring barley depends on the doses of fertilizers in the field crop rotation and the ratio of nutrients in them. The largest share is nitrogen (65–122 kg / ha), followed by K2O - 47–92 and P2O5 26–51 kg / ha. From 1 ton of grain and the corresponding amount of straw, spring barley of the Commander variety removes 19.2–22.4 kg of nitrogen, 7.8–9.2 - P2O5 and 14.0–16.8 kg of K2O from the soil, depending on the fertilizer and saturation of field crop rotation with different types of fertilizers. Straw is an important source of soil organic matter reproduction and the return of nutrients used for crop formation. Depending on the system of fertilization, 17–25% of nitrogen, 25–30% of phosphorus and 68–69% of potassium are returned to the soil with spring barley straw via economic removal. It is specified that spring barley of the Commander variety absorbs N, P2O5 and K2O in the following ratio: 1: 0,4: 0,3 to form a unit of grain yield and the corresponding amount of straw in the conditions of podzolic black heavy loam soil of the Right-Bank Forest-Steppe.

Purpose. Study of the anatomical and morphological structure of the stem of winter wheat hybrids depending on fertilization backgrounds and seeding rates in agrocenoses of the Right-Bank Forest-Steppe natural zone of Ukraine. Methods. Observation, comparison, analysis and synthesis, forecast, field experiment. Results. The study of the dynamics of formation and functioning of the anatomical and morphological structure of the stem of winter wheat plants was carried out. The influence of the background without fertilizers and against the background of their increased level of application on the length of internodes (1-3) of stems in winter wheat agrocenoses was studied. It has been proven that seeding rates significantly influenced the length of the internodes. The influence of the background of mineral nutrition and seeding rates on the main anatomical and morphological parameters of winter wheat stems, in particular, the thickness of the stem and ring of mechanical tissue, the number and diameter of vascular-fibrous bundles was studied. It was found that the strength of the straw is largely determined by the number of vascular-fibrous bundles, as well as their diameter. It was the biggest on the variants with the increased fertilization background. It is noted that anatomical and morphological studies are needed in order to ensure the development of a more durable straw, which determines high resistance to lodging at a seeding rate of 3 and 1.5 million seeds/ha. Conclusions. On the basis of the conducted studies, it was found that the soil and climatic conditions of the years of the study and the factors that were studied have a direct influence on the anatomical and morphological parameters of wheet. At the same time, the best conditions for the maximum realization of the potential of the Patros hybrid of winter wheat plants were created in the experimental variants with a seeding rate of 3 and 1.5 million seeds/ha, ensuring the development of a more durable straw, which led to a high resistance to lodging.

The influence of long-term application of potassium-deficient fertilizer system in the field crop rotation (winter wheat, corn, spring barley, soybeans) on podzolic heavy loam black earth of the Right-Bank Forest-Steppe of Ukraine on potassium content in plants, its costs for formation of one unit of the harvest was determined; potassium balance was calculated and the effectiveness of different doses of potassium fertilizers was comprehensively assessed. It was found that the potassium content in grains and seeds of agricultural crops under the influence of potassium fertilizers varies by no more than 8%, while in straw and stalks - by 10-24% depending on the variant of the experiment. It is shown that the non-grain part of the crop contains a significant part of potassium - 50-80% of economic removal depending on the crop. It is calculated that if it is left in the field for fertilizer in the variant of the experiment Basis + K80, it compensates for the consumption of potassium by 71%. By applying K40 and K80on the basis of applying N110P60 and leaving the non-commodity part of the crop in the field for fertilizer, the balance of potassium in the soil is formed positive with intensity of 111 and 212%, respectively. According to the index of complex assessment, which takes into account seven indicators: payback of 1 kg of mineral fertilizers; additionally conditionally net profit; net energy profit; humus balance and intensity of nitrogen, phosphorus and potassium balance, the best variant of the experiment is application of N110P60K40 per 1 ha of field crop rotation area. This indicates the possibility of a temporary reduction in the dose of potassium fertilizers in field crop rotation on podzolic heavyloam black earth in the Right-Bank Forest-Steppe of Ukraine

Purpose. One of the main factors holding back the increase in spring barley yield is high soil acidity in the Forest-Steppe and Polissya natural zone of Ukraine. Aluminum is a major toxic factor of acidic soils. Therefore, one of the ways to increase the yield of barley is to create aluminum-resistant varieties of this crop. These studies are aimed at obtaining, highlighting the results of work and determining the prospects of selection for the creation of varieties of spring barley, tolerant to the effects of edaphic stress of high soil acidity. Methods. Field (phenological observations and accounting), laboratory (establishment of aluminostability of collection varieties), biometric and measuring-weight (for accounting of productivity and yield), mathematical and statistical (objective evaluation of the obtained experimental data). Results. Research on the evaluation and creation of promising breeding material and varieties adapted to high soil acidity was conducted in the experimental fields of the Institute of Feed Research and Agriculture of Podillya of NAAS (2013-2019). According to the results of the research conducted in the laboratory, the potential 73 aluminium resistant varieties of spring barley were established, and the results of verification of the obtained data in the field against the background of natural high soil acidity were shown. The obtained research results made it possible to select samples that are potential donors of tolerance to the toxic effects of Al3+ ions and high soil acidity. Promising breeding material of spring barley, tolerant to the effects of edaphic stress of high soil acidity, which is effectively used in the creation of new varieties of spring barley has been cteated. Conclusions. Evaluation of productivity of the studied samples, which were isolated by laboratory evaluation of potential aluminium resistance, in the field on a natural background with high soil acidity (pH 4.3-4.8) confirmed the effectiveness of this method in the selection process, aimed at creation varieties tolerant to cultivation in conditions of highly acid soils.

In order to obtain a significant level of yield of table carrots in the Right-Bank Forest-Steppe of Ukraine, it is necessary to select varieties and hybrids in accordance with the soil and climatic conditions of cultivation. The comparative estimation of productivity of hybrids of carrots of table foreign selection in the specified conditions is carried out. The results of phenological observations of plant development, their biometric indicators depending on the genetic features are presented. The indicator of the total yield of table carrots according to the experiment was in the range of 65.6–80.7 t/ha. Saturno F1 had higher and this exceeds the control of Abaco F1 by 15.1 t/ha. In the structure of the yield of this hybrid marketable products are 96.0 % or 77.1 t/ha, which is more than the control of 5 % or 17.1 t/ha. In Saturno F1 non-marketable products 3.6 t/ha, which is 2.0 t/ha less than the control, and the yield of standard products 75.3 t/ha, which is a larger indicator of the experiment and exceeds the control by 17.3 t/ha. Non-standard products amounted to 1.8 t/ha. The productivity of table carrots is significantly influenced by the weight of the root, which, in turn, is affected by its length and diameter. On average, according to the years of research, their weight was at the level of 190–240 g. The roots in Abaco F1, which was the control, were smaller in weight. Larger roots formed in Saturno F1. Hybrids Baltimore F1, Bolivar F1 and Gerada F1 formed roots of 208 g, 218 g and 233 g, respectively. The diameter of the roots of the studied carrot hybrids was 4.6–5.2 cm. They were smaller in Saturno F1 and larger in Baltimore F1. The average values of root diameter for the years of study in Abaco F1 (control) are 5.1 cm; Bolivar F1 4.7 cm, and Gerada F1 5.0 cm, which is less control by 0.4 and 0.1 cm, respectively. An important varietal feature of table carrots is the length of the root. In Abaco F1 it was 18.5 cm. This is the lowest value in the experiment. In Baltimore F1 and Bolivar F1 the roots were formed of almost the same length 19.0 and 19.3 cm, respectively, which is more control by 0.5 and 0.8 cm. In Gerada F1, the roots were 23.2 cm, which is more control by 4,7 cm. Roots of Saturno F1 were longer compared to other variants of the experiment 24.5 cm, which is more control by 6 cm. The suitability of the studied hybrids of table carrots for foreign selection for growing in the conditions of the Right-Bank Forest-Steppe of Ukraine has been established.

The article presents the results of spring barley crops and the effect of foliar fertilization on them. Prospects and effectiveness of biological products as a basic fertilizer for cereals. Spring barley is a valuable food, fodder and technical crop. Pearl barley and barley groats are made from vitreous and coarse-grained two-row barley grain. Most barley is used for feed purposes. In 1 kg. grain contains 1.2 feed units and 100 g of digestible protein. Spring barley contains a lot of protein (9-12%), carbohydrates (70-75%), pentazoles (7-11%), sucrose (1.7-2%), fiber (3.8-5.5%), fat (1.6-2%), ash (2-3%). Spring barley grain is characterized by high nutritional value and is widely used in feed production, confectionery, brewing. However, in the dynamics of its yield there are significant fluctuations, which is associated with both agro-climatic conditions and organizational and economic. Having a short growing season, underdeveloped root system, the culture is quite demanding on the provision of basic factors of plant life, including nutrients. The system of fertilization of spring barley is determined primarily by predecessors. It has a valuable ability to make the best use of the aftereffects of organic and mineral fertilizers applied to the previous crop. If spring barley is sown after well-fertilized row crops (sugar beet, potatoes), under which 40-50 t / ha of manure and mineral fertilizers are applied within N80P80K80 - N120P120K120, then fertilizers are not applied directly under barley at all. Against this background, barley with proper care can form 40-50 kg / ha of grain. It is clear that in case of incomplete supply of sugar beets or potatoes with fertilizers, barley will require additional application of macronutrients. Barley responds very well to fertilizer application, especially in conditions of sufficient moisture. The increase in yield from mineral fertilizers can reach 15-20 kg / ha. To prevent lodging of plants, it is necessary to ensure the correct ratio of nutrients - nitrogen, phosphorus and potassium. Given the condition of the soil cover and low volumes of fertilizer application, we consider the issues of optimization of mineral nutrition of spring barley to be relevant and in need of refinement. An important component of the plant nutrition system is the use of microfertilizers. Therefore, the purpose of our research is to establish the reaction of spring barley to the complex use of microfertilizers, crop formation and grain quality in the conditions of the Right-Bank Forest-Steppe of Ukraine [3] Key words: spring barley, foliar feeding, biological products.

The research results of the influence of fertilizer systems on the productivity of spring barley in the Right-bank Forest Steppe were presented. Traditionally fertilized backgrounds were studied: mineral, organic and organomineral (with half fertilizer rates of previous backgrounds), and the alternative to organic matter was cereal straw and biomass of green manure crops. The best backgrounds and optimal fertilizer systems for high level of grain yield were determined. The main factors that formed the productive plant density of spring barley were the rates and types of fertilizers. The improving of plant nutrition due to using of organic and mineral fertilizers led to an increase in the productive plant density in the agrocenosis and the competitiveness of plants, the reducing of weed infestation. Depending on the type of fertilizer, the grain yield of spring barley changed. Based on the research results, it was found that the combination of traditional fertilization with the application of alternative types of organic matter increased the grain yield of barley spring compared to the control variant on mineral background within 1.61–2.04 t/ha, organic – 1.69–2.14 t/ha, organomineral – 1.79–2.19 t/ha. At the same time, the yield indicators had a range: 4.86–5.29 t/ha on the mineral, 4.94–5.39 t/ha – organic and 5.04–5.44 t/ha organomineral background. The highest yield of spring barley was provided by a combined fertilizer system with half norms both mineral fertilizer and manure against the background of the afteraction of predecessor straw with compensatory dose of N10/t and green manure biomass of white mustard as organic fertilizer, and equaled of 5.44 t/ha (yield gain was 2.19 t/ha compared to control). The optimal fertilizer systems to increase of spring barley yield in conditions of the Right Bank Forest Steppe are combined mineral, organic and organomineral fertilizer systems, which include the use of traditional fertilizers: the action of mineral fertilizers and the afteraction of manure, as well as alternative fertilizers – the straw of predecessor with a compensatory dose of N10/t in combination with the white mustard biomass. Keywords: spring barley, predecessor by-products, mineral fertilizers, yield, fertilizer systems, grain quality.
