The article presents the results of studies on the use of different amounts by weight of triticale grain in feeding of young geese raised for meat. In the first group the wheat grain was 50% replaced by triticale grain, and in the second group the wheat was completely replaced by triticale grain. As a result of the experiment it has been found that the replacement of wheat by triticale in complete feed for geese provides a high growth rate but at 50 % inclusion of triticale grain the live weight at the end of the experience was110.8 g or 3% higher, as compared with the second group. It should be noted that up to 49 days old geese receiving compound feed with the 100 % replacement by triticale grain had a higher body weight. Complete replacement by triticale grain favoured the increase of carcass yield by 2.2% and decrease of body fat by 68.7 g as compared with the first group. Muscle tissue of the goslings fed the complete feed with complete replacement for triticale grain was characterized by 1% lower caloriс content than the goslings of the second group. According to biochemical composition of blood, all designed rations ensured normal metabolism in the fattened geese. The inclusion of triticale grain into the complete feed for young geese reduced their costs in the second group by 2.9%. But as a result the higher profit by 18.75 % was in the first group, which contributed to increased profitability by 2.4%. It is recommended to use up to 50% of triticale grain instead of wheat as part of complete feed for young fattening meat geese
In recent years, due to the increasing aridity there was
an increase in the frequency of epiphytoties leaf disease
of barley. Therefore, we can see now how greatly
increased the need for the creation of resistant grades.
Introduction of the selection marker will significantly
speed up the breeding process for resistance to
pathogens. Employees of the All-Russian Institute of
Plant Protection recommended three genes - Rpt 1b,
Rpt 5, Rpt 6 to control the resistance to the pathogen
Pyrenophora teres for use in breeding programs in the
North Caucasus. Rpt 5 gene is one of the most efficient
one, because it determines the resistance to the eight
isolates of the fungus Pyrenophora teres of different
origin. In 2011, Australian scientists have discovered
microsatellite markers called Bmag0173 and HVM74,
closely linked to the gene Rpt5, which are used very
effectively in order to marker-assisted selection of
resistant grades in Australia and Canada. Due to the
urgency of creating new genotypes carrying resistance
genes to net blotch, that would be effective in the
Southern Federal Region, the staff of All-Russian
Scientific-research institute of Grain Crops after I.G.
Kalinenko and the All-Russian Research Institute of
Plant after N.I. Vavilov has developed a practical
strategy for the use of molecular techniques to create
barley grades resistant to this pathogen, which is being
successfully implemented

The process of the presowing seed treatment with alternating electromagnet field of the commercial frequency (EMF CF) 50 Hz is economically efficient. The use of the EMF CF 50 Hz in the unit with ring pole pieces allows increasing the germinating energy and power. The electromagnet seed treatment in the units with ring pole pieces is the perspective process of the presowing treatment which does not make unhealthy influence on the operating personnel. At the presowing treatment we have to take into account three factors, they are the arrangement of seeds in the working chamber, the time of treatment and the seed humidity. In this article the authors recommend to promote the unit consisting of a magnetic circuit with ring pole pieces of the rectangular cross-section, a magnetizing coil and an embedding of the non-magnetic material in the working chamber which allows increasing the germinating energy of spring barley by 10% and the germination by 7%. As field experiences have shown the highest seed germination and good crop capacity take place in the work chamber zone with boundaries R1=0,012 m and R2=0,035 m at seed humidity from 12% till 18% and the time of seed treatment is 0,9-2,75 s. The addition to crop capacity has run to 7% as a result of the spring barley treatment
The peculiarities of development of “phragmites australis” are analyzed at this article. The reed effect on the covering materials is investigated. The laboratory experiments are executed. The sizes of pressure, with characteristic of the generation period, are determined
The article presents the results of studies of 92
indigenous varieties and 15 wild genotypes by 24
microsatellite markers. As a result a locus database about
germplasm in the collection stored at the Russian
ampelographical collection AZOSViV (Anapa Zone
Experimental Station of Viticulture and winemaking)
was created. During the research of varietal breeding
populations confirmed the validity in the production of
the cultivar of Krasnostop anapsky with obvious changes
in microsatellite sequences as a clone of famous indigenous
Don cultivar Krasnostop Zolotovskii. This clone
was selected in 1953 by prominent agrotechnologist
Zotkin Ivan Ivanovich which is propagated by the
author and his followers, and after a formal registration
submitted to state testing in 2007 in GSK RF, zoned in
the North Caucasus region (number 6) in 2014 year. Sort

techniques, now clonal selection of vine grapes is reasonably
improving. Recent data collected by us in the
work process, were analyzed a comprehensive manner,
making it possible to draw conclusions about distinctness
of grape varieties. Some clones were studied by DNA
primers, based on retrotransposon sequences

The article studies the influence of the interaction of two technologies of plant protection: breeding- immunological and chemical. The studies were conducted on the varieties and lines of soft winter, durum wheat and triticale, established in Krasnodar research institute named after P. P. Lukyanenko, and also, on varieties of an alien and foreign selection. When considering the correlations in the group of genotypes, forming a necrotic type of reaction to the introduction of the pathogen (the first group of varieties), the significant negative correlation (r - 0,76) between the change in the mass of 1000 grains and the number of unproductive stems formed by one plan was established. The model of the severity of brown rust pathogen in sparse crops of wheat has been collaborated. According to the model, the development of the pathogen in the tissues of the leaves of the host plant leads initially to a change in the relations of the productive and unproductive stems. The change of these parameters significantly affects on the variability of indicators such as the mass of grains from one ear, number of grains per ear and 1000 grain weight. Negligible volatility of weight for 1000 grains suggests that the major losses of productivity in the flowering stage are due to abortive flowers. This model can explain the increase in the mass of 1000 grains in some varieties for tolerance change experiments with the defeat of plants of P. Triticina on micro-plots
