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 244
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

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 352
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

PLANT HEIGHT AND LODGING RESISTANCE OF COLLECTION VARIETIES OF WINTER BARLEY

abstract 1331709015 issue 133 pp. 160 – 172 30.11.2017 ru 599
Lodging resistant is a very important factor of limitation of the yield of barley. The yield of lodged crops may be decreased up to 50%. The quality of the yield also deteriorates which negatively affects brewery characteristics. The lodging resistance of a variety is determined genetically and depends on a plant height and weather conditions during dynamic vegetation. One of the main aims of breeding of the crop for lodging resistance is the selection of short-stem varieties. However, a thorough study of the basic material and determination of its adaptability to a particular soil and climatic zone and suitability of its usage as parental forms are needed. The article covers the plant height of collection varieties of winter barley in the central zone of Krasnodar region and determines the groups of the varieties based on this trait. The dynamic of plant height formation depending on the vegetative conditions during five years is studied. The examination of lodging resistance of winter barley revealed that there are many non-lodging forms of the crop. New local varieties and lines have short and strong culms. Also, some varieties from Western Europe and the USA show its good lodging resistance under these conditions

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

abstract 1121508119 issue 112 pp. 1640 – 1650 30.10.2015 ru 925
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

RETROSPECTIVE ANALYSIS OF THE WINTER BARLEY VARIETIES ESTABLISHED IN THE SOUTH OF RUSSIA

abstract 1231609024 issue 123 pp. 347 – 365 30.11.2016 ru 1073
Barley (hordeum vulgare) is a valuable food and forage crop. It is cultivated in the world on an area of about 60 million hectares. A major region of barley cultivation in the Russian Federation is the Southern Federal District. The variety is one of the main factors determining the demand for crop. To use the varieties effectively we must have a complex of economically valuable traits such as hardiness, resistance to lodging, disease and pest resistance. These traits make it possible to generate the harvest high and stable from year to year. The article is devoted to the analysis of winter barley varieties, created in the south of Russia from ancient times to the present day. The main achievements of the leading Russian breeding facilities and experienced breeders of scientists set out in chronological order. The article describes the methods and principles of selection (from individual selection to mutagenesis and complex selective breeding) used to breeding the new varieties of winter barley. The most attention is given to the outstanding varieties included to the mating program today
