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
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
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
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
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
