The article covers the stages of evaluation and
selection of new self-pollinated corn lines. The results
of testing of new lines and test crosses were reflected.
Comparative analysis of yield of the best test crosses
was presented. General and specific combining ability
of new lines was calculated. The opportunities of
further usage of new lines in breeding programs and
early maturing hybrids including these lines are
considering. The researches were conducted on the
field of the institution, following the course of
scientific researches of department of selection and
seed management of corn, Federal State Budgetary
Scientific Organization Krasnodar Lukyanenko

The results of primary screening of bacterial strains on the basis of cell-wall degrading enzymes and antifungal activity against the fungus Fusarium graminearum. Selected active strains perspective for the development of biopreparations based on their type of multifunctional action to protect fall wheat from Fusarium pathogens are given
During 2012-2015 from the two fissile populations
of rice hybrid Il.14 x Kuboyar and Il.28 x Kuboya
we conducted multidirectional selection of panicles
with low, medium and high number of grains in
them. It was established a different reaction to the
selection of hybrid generations by yield. The lowest
yield was formed at planting grain from small panicles,
intermediate - from the middle panicles and
biggest - from the major panicles. The reaction to
selection decreased with each successive generation.
In the hybrid Il.14 x Kuboyar at positive selection of
the yield increase towards the initial population F2
was in F3 - 10,5%, in the F4 - 3,8% and F5 - 1,9%, at
Il.28 x Kuboyar - respectively 4, 4%, 3.1% and
0.7%. At negative selection in Il.14 x Kuboyar there
was a decrease of yield on 7.7% F3, in F4 on 6.9%
and in F5 on 0.2%. By years of research was not observed
variations in grain yield obtained from the
panicle with an average grainness and generally was
at the level of the original population. At the hybrid
Il.28 x Kuboyar for negative selection of the relative
yield initially decreased on 1.7% in F3, while then for
all kinds of selection to the fifth generation grew up
and different to a lesser extent than the first the hybrid,
although the ranks of the values preserved. The
yield from a fraction of well-grained was 98.4%,
medium grained - 96.5%, low grained - 94.2% of the
initial Kuboyar variety
The article looks at the current state of energy in Vietnam and the selection of new Russian steam turbines for operation in combined gas-steam plant in Vietnam. The calculated results of thermal performance scheme 3x1 with combined gas-steam plant 1090 MW based on the Russian steam turbines K-330-240-2 and on the steam turbines TS2A40 Mitsubishi (station PhuMy-1, Vietnam). It also looks at the influence of the efficiency of high-pressure cylinders of Russian steam turbine K-330-240-2 on the efficiency and power of a gas-steam plant 3x1 with 1090 MW, increasing the efficiency of high-pressure cylinder of steam turbine through the use of honeycomb seals in flow part
It is highlighted, that the development of measures for
the selection of the optimal model of urban public
transport organization in Magadan requires an objective
evaluation of factors of its surroundings and evaluation
of the degree of their influence on municipal transport
infrastructure in general. It was revealed, that urgent
measures for solving problems of integrated
management from the direction of municipal
government are required. As a result, the principal
trends of public transport development in a northern
town are determined, and some recommendations on
improving public transport management efficiency
from the direction of local authorities are given
There were cited the results of the comprehensive assessment of the initial material of tomatoes with the marker signs for the aim of their use in the selection of heterotic hybrids of tomatoes on an open ground in Krasnodar region
The article shows the results of integrated assessment of variety-rootstock combinations of plum on clonal rootstocks and different schemes of landing. We have defined the basic biometric parameters of trees, and specific indicators of productivity, allowing to identify the most optimal variety-stable rootstock combination for the conditions of the Krasnodar region
In the conditions of Krasnodar region variety-rootstock combinations of plum Russian in the period of growth and fructification for the purpose of allocation of best of them for use in intensive technologies of cultivation are studied. The most weak, productive, fast-grown variety-rootstock combinations are allocated. They represent the greatest value for use in technologies of intensive type by production of fruits of Russian plum
The content of selenium in the soils of various genetic types varies widely. Its amount is lower in soils formed on volcanic rocks. On average, it is 0.2-0.6 mg/kg. In the soils formed on sedimentary rocks, the content of selenium is often in the range of 4.5-5.0 mg/kg and depending on the conditions of formation it varies widely, sometimes reaching 100 mg/kg. Predominantly they are alkaline soils, selenium concentrations in the soil solution is 10-6 moles. The content of selenium in most soil types of the Russian Federation and CIS countries varies in the range of 0.01-1.0 mg/kg. Floodplain, chestnut soils, black soils and gray soils are more enriched (0.3 to 1.0 mg/kg), whereas sod-podzolic and sandy soils are relatively depleted (0,05-0,2 mg/kg). Systematic application of mineral fertilizers on the fields of crop rotation leads to a decrease in total content in the leached black soil. Fertilizers contribute to increased mobility of this element and more intensive involvement of it in the biological cycle
The article is devoted to the study of peculiar features of mental processes verbalization in the contemporary English discourse. The choice of the mentalist or cognitive approach to the object of study is explained by its complexity; so this very approach will help to view upon the dynamic characteristics of psyche as upon the object of study and as the method of study at the same time
