Description
The results of studying the ordinary pine condition in geographical cultures of the Central forest-steppe are cited in the article. The general pattern of the ordinary pine intraspecific variability is represented. The data of origin influence on safety, efficiency, qualitative adjectives is presented. The pattern of ecotypes adaptability to new environment conditions is presented

PROTEINS OF AFRICAN SWINE FEVER VIRUS
Description
The review presents some data on structural and non-structural, regulatory proteins and enzymes of African swine fever (ASF) virus. The variety of the virus biological characteristics is substantially caused by proteins belonging to multigenic families. It is suggested, that the protection development at ASF is provided not only by the membrane proteins, but also by the regulatory ones

POLLEN ANALYSIS IN PLANT BREEDING
Description
Different aspects of applying the pollen analysis were studied in plant breeding. Fertility, pollen viability, change of pollen morphological characteristic were used by basic characteristics. Connection between pollen analysis and plant reproduction potential have been analyzed

Description
The immunologic characteristics of 18 domestic winter wheat cultivars to Transcaucasia population of yellow rust pathogen have been studied. 251 resistance sources to Puccinia striiformis have been detected among 468 studied soft wheat samples from Vavilov ARRIP collection. The efficiency of known resistance genes (Yr) to Transcaucasia population of yellow rust pathogen are estimated

-
Description
Qualitative and quantitative composition of the low-molecular carboxylic acids (CA) which were contained in the cultural liquid (CL) of the four strains of Escherichia coli and Salmonella enteritidis var.Issatchenko was investigated. The differences in the composition of the CA were shown, their dynamics during the bacterial growth and their total concentration in CL were strain specific characteristic. The differences in the composition and dynamics of the CA, which are specific only to probiotic and opportunistic strains were revealed

JUSTIFICATION OF SPAR ROADS JUNCTION ANGLES TO THE FOREST ROADS
Description
The zone of attraction of hauling branches in an allocation scheme based on the roads in "herringbone" forest resources is divided into 'near' and 'distant' parts with respect to location of contiguity point to forest road. In the "distant" part at certain parameters of cutting area, it is advisable to lay spar roads to a branch at an angle equal to the optimal angle of junction of branch to line, which reduces the cost of removal of wood on the branch. In the "near" part, as well as in forked and combined schemes of road allocation in forest resources , spar roads should be run under the best angles determined by established analytical relationship to reduce the cost of removal of wood
