In this article, the results of the research of quality
characteristics of Russian rice varieties were observed
Series of field and laboratory studies were conducted from 2011 to 2012 in Russian State Agrarian University to evaluate a collection of 4 turf grass species and 15 cultivars for quality, summer density, ground cover and germination percentage. During 2 experimental seasons the plants have been growing with the extensive treatments. Turf quality was evaluated visually using a 1 to 9 scale. The two-way analysis of variance was used to identify genotype’s effects on density, ground cover and germination percentage
Increasing the productivity of agricultural plants,
including rice, is the most important area of breeding.
The creation of varieties with vertically leaved
architectonics allows to have a qualitative approach
not only to the process of formation of a highly
productive agrocenosis, but also to solve questions of
assessing the productivity of rice. To create highly
productive varieties, it is necessary to develop new,
more efficient methods of selection
In the process of long evolution chestnut soils of the Eastern Ciscaucasia passed hydro morph, semi and auto stages of soil formation, accompanied by the leaching of salt, carbonates and dehumidification

The gaining of maximum amount of daily young
animals in a greater extent depends on disinfection of
incubation eggs which in complex of veterinarysanitary
arrangements held in poultry factories on
prevention and elimination of poultry infectious
diseases takes an important part. The perspective of
ozone application in industrial poultry breeding is
conditioned with its advantages which it
characterizes in comparison with other chemical
substances. It was settled that ozone has a special
ability to detain the growth of fungi on biological
substrates, also the process of mould appearance on
the surface of eggs’ shell even at 90% of relative
moisture. At substantiation of parameters and
regimes of electro-technological process of egg
storehouse ozonation there were implemented the
experimental researches. The general bacterial
semination of eggs’ shell decreased on 94,1% after
disinfection of incubaion eggs with ozone.
The relative faults of experimental values from
theoretical ones are 7%. In the result of production
trials there were set the parameters of quality of the
worked out electrotechnological process of egg
poultry factory storehouse ozonation: time of
regulation ‒ 8 minutes, dynamic fault ‒ 0,9,
coefficient of overcorrection ‒ 4,5%, generalized
integral mean-square index ‒ 10,6%. Obtained data
testify against the qualitative regulation of allocation
of concentration of ozone in a egg storehouse

In the article we have studied the exterior of golshtinizaited animals. The increase in number of measurements for specific dairy type and increase of productivity has been established
Two methods were used for DNA extraction from herbarium leaves of two subspecies: V. vinifera subsp. sativa D.C. и Vitis vinifera ssp. silvestris Gmel. DNA extraction is difficult from herbarium leaves plants because of the presence of metabolites that interfere with DNA isolation procedures and downstream applications such as DNA restriction, amplification, and cloning. The quality of DNA was checked on a spectrophotometer by measuring the level of absorption at A260/280 nm. The results showed the successful extraction from mature and dried leaves of DNA when using the СТАB-method №2. Another method hasn’t shown satisfactory results in amplification of DNA
