ACREAGE AND YIELD OF WINTER BARLEY IN THE MAJOR REGIONS OF GROWING

abstract 1121508119 issue 112 pp. 1640 – 1650 30.10.2015 ru 610
The article presents a comparative analysis of national economic importance of winter barley in relation to other crops. The advantages of winter barley in a number of factors have been observed. The information about acreage under crop and gross yield of this crop is presented in an article in the form of tables. The authors have studied such important factors as a dynamics of acreage of crop yield in the main regions of cultivation. Against the overall negative dynamics of sown areas, they noted a clear increase in 2013. An analysis of grain yield of winter barley in the main regions of cultivation by year has been presented graphically. Special attention was paid to the Southern Federal District and the Krasnodar Territory in particular as a major producer of grain of winter barley. The analysis of yields in the major regions of cultivation of winter barley showed a clear advantage of the Krasnodar region. The index of the average grain yield of winter barley cultivation in this region for the period from 2003 to 2008 has been shown. Moreover, the article has presented the role of sorts in increasing the yield grade. We have also highlighted the issue of selection of winter barley in our country. The desirability of increasing the production of winter barley in the Russian Federation has been noted as well

ANALYSIS OF RESPONSE OF THE YIELD DEPENDING ON THE DURATION OF VEGETATIVE PERIOD OF WINTER BARLEY VARIETIES

abstract 1321708074 issue 132 pp. 951 – 964 31.10.2017 ru 154
Duration of vegetation period is one of the main adaptive traits for any crop or variety. Reasonability of cultivation of a variety in a particular soil and climate zone is determined by the duration of the vegetative period. One of the aims of breeding is the creation of the varieties with the main vegetative phases lasting at more favorable climatic conditions. The most accurate way to determine maturity group of a variety is by estimation of starting of heading phase, which can be defined with the greatest precision. The article covers the analysis of the duration of the vegetative period of the lines and varieties of winter barley of local and foreign selection in the central zone of Krasnodar region. All the varieties were divided into three maturity groups. The vegetative periods of the varieties were studied during four years. The most favorable and adverse conditions for yield formation were determined. The interactions between the productivity of the varieties depending on maturity group were identified. The varieties of the early maturity group which are more productive than the check were selected, which is most valuable for the breeding of the crop. The best varieties with the high and stable yield and the positive traits are regularly involved in the breeding programs with the porpoise of making new varieties of the winter barley

ASSESSMENT OF FROST RESISTANCE IN WINTER BARLEY VARIETIES

abstract 1572003020 issue 157 pp. 271 – 281 31.03.2020 ru 8
The article presents the results of the research on the evaluation of frost-resistant varieties of winter barley. Frost resistance is the main criterion for winter hardiness of winter crops. To promote the area of cultivation of winter barley in colder areas, production needs high-hardy varieties. Recently, due to the warming of the climate in the Central zone of the Krasnodar region, it is almost impossible to reliably and accurately determine the winter hardiness of winter crops in natural (field) conditions. In this regard, breeders in their work, in order to identify frost-resistant forms, use the method of direct freezing of breeding and collection material. During our research, the evaluation of the test material was carried out using a modified method developed by academician V. M. Shevtsov. This method allows the most accurate and efficient determination of the critical temperature for a particular sample in a short period of time. Varieties and lines were placed in the EKSI refrigeration unit for a certain period of time. Then they were taken out, and at the end of time, the percentage of plants before and after freezing was calculated. As a result of the conducted research, we have selected highly frost-resistant forms that differ in a complex of economically valuable features and properties

CONDITION OF BARLEY PRODUCTION IN THE RUSSIAN FEDERATION

abstract 1061502070 issue 106 pp. 1071 – 1082 28.02.2015 ru 786
The article presents an overview and in-depth analysis in the area of barley grain production. The statistical data and comparative analysis of total yield of barley in the Russian Federation with respect to other cultures, widely cultivated in our country, such as sunflowers, oats and wheat has been presented. The structure of sown areas occupied by the culture of barley in the Russian Federation for the period from 1990 to 2013 has been presented graphically; we have analyzed the trend of their increases and decreases over the years. The article presents and visually shows a comparative analysis of crops like winter and spring barley. At the same time, due to a significant warming, distinct advantages of winter crops to spring crops in the cultivation of them in the southern regions of the country have been noted. The recommendations on the feasibility of increasing the cultivated area were made. Indicated by the national economic significance of culture, we show the examples of its use in industrial processing. In addition, long-term analysis of statistical data on the yield of major crops grown in the Russian Federation, such as wheat, barley, maize, millet, oats, rice, legumes, sunflower, soybean has been performed

CYCLICAL EFFECTS OF ACTINOMYCIN D ON THE BARLEY COLEOPTILES GROWTH

abstract 1071503088 issue 107 pp. 1342 – 1361 31.03.2015 ru 1027
In cell biology, actinomycin D is shown to have the ability to inhibit transcription. Actinomycin D does this by binding DNA at the transcription initiation complex and preventing elongation of RNA chain by RNA polymerase. When soaking the seeds in a solution of actinomycin D, antibiotic blocks RNA synthesis and seed germination occurs at the expense of long-living RNA, available in the mature seed. In the article we present experimental data indicating that as storage seeds of winter barley are changing the action actinomycin D on the growth of coleoptiles. It is shown that actinomycin D at a concentration of 40 µg/ml in October reduced the growth, in December it was not authentically, and in February it was paradoxical amplified growing coleoptiles. We suggest the part of the actinomycin D fastened with growth inhibitor coleoptiles, whose structure changes during seed storage and increase the affinity of actinomicyn D to the inhibitors. At a concentration of 60 µg/ml actinomycin D effectively reduced of the coleoptiles growth. Suppression of seedlings roots growth was proportional to the concentration of the actinomycin D and exposure time

INFLUENCE OF THE DENSITY OF STALKS OF WINTER BARLEY VARIETIES ON THE FORMATION OF SOWING QUALITIES OF SEEDS

abstract 1521908005 issue 152 pp. 35 – 44 31.10.2019 ru 8
The quality of the seed largely depends on the value of the future crop. For sowing, it is necessary to use seeds with high sowing qualities. This article is devoted to the study of the formation of high-quality seed of new varieties of winter barley, depending on the controlled compaction of crops. The paper describes in detail the importance of sowing qualities of seeds for the formation of high productivity of barley crops. The questions of influence of different seeding rates on laboratory and field germination of seeds are considered. The correlation between the four variants of seeding rates and field and laboratory germination was determined. The purity of seeds of winter barley varieties Kubagro – 1 and Kubagro – 3 was studied and it was determined that the change in the density of the formed stem does not affect the purity of seeds of these varieties. The use of highly productive seeds for sowing and further qualitative cleaning of the obtained grain contributes to the production of seed material with high purity. When considering the weight of 1000 grains in the studied varieties, it was determined that with an increase in the number of productive stems per unit area and a decrease in the area of plant nutrition, both varieties reduced the mass of grains. The highest rates of weight of 1000 grains were determined when sowing with the norm of 3.5 million germinating seeds per 1 ha, such a pattern was observed for both varieties
