Description
The possibility of the ISSR-markers application for systematization and genetic certification of the genus Rhododendron is showed on the basis the research of 25 species and intraspecific taxons. The way of recording of genetic passport on the basis of amplicons size is suggested

Description
As result of evaluation 24 common wheat introgression lines with genetic material Agropyron glaucum the considerable variability of resistance to leaf rust was revealed. Genetic control of leaf rust in introgression lines 60 and 109 was studied using hybridological analysis. Both lines contained single dominant genes differed from each other and from the known effective Lr19 and Lr24. The investigated lines with genetic material Agropyron glaucum are valuable donors of the genes for leaf rust resistance

EVALUATION OF THE QUALITY OF WHEAT MALT GROWN USING ELECTRO-ACTIVATED WATER SOLUTIONS
DescriptionThe present review highlights possibility of obtaining wheat malt by using electro-activated water solutions obtained by electrolysis

Description
Estimation of blast resistance of rice breeding lines, carrying resistance genes Pi-b, Pi-z and Pi-40 has been done. For phytopatological test isolates of pathogen from Krasnodar territory were used. As the results of the study Pi-40 gene showed maximal resistance to blast isolates. On the other part, rice line, carrying both genes – Pib and Pi-z showed significantly higher level of resistance with compare to standart variety Khazar

Description
Professional apple gardening is bound to particular risks, of which is essential losses of a harvest because of diseases. An apple scab, the caused Venturia inaequalis (Cooke) G. Winter, brings the greatest loss. The main approach in monitoring of a scab of an apple-tree is creation of grades, steady against pathogen. In the present work we have carried out phytopathology testing of generations of the seedlings received from the free pollination of six forms of a crab of Malus orientalis from a collection MOS VIR (Maykop) characterized by a relative resistance to the apple scab in 2-3 classes of damage by long-term data. For infection we used inoculum, consisting both of natural population of a scab, and of strains of pathogen of various cultivars and geographical origin. When carrying out padding infection increase in force of an infectious background that can be bound to selection of the plants of biotypes of a fungus that are most adapted for genotypes was noted. It is recommended for precise elimination of unstable plants at selection at early stages of an ontogenesis to carry out more than one serial infection during the season. By results of the phytopathological testing, we highlighted three Malus orientalis forms from the six studied No. 17982, 17985 and 3080 the most perspective stability genes for an introgressiya in a cultural gene pool of an apple tree

Description
The results of study of production process of winter wheat amid of changing of agro ecological conditions such as seeding time, level of initial fertility, fertilizer system and variety throughout 3 year-research are shown in the article. Five hypotethetical systems are pointed out with the help of factorial analysis. Detached varieties and research years are pointed out in terms of their factorial influence

STATE EVALUATION OF WOODY PLANTS IN ROSTOV-ON-DON
DescriptionThere has been conducted the analysis of woody plants quantity in various types of stands in Rostov-on-Don, as well as the evaluation of their state and the rate of environmental resistance destabilization. It has been ascertained that the stands of almost all of the urban gardening objects are in a salvaged condition. There have been elaborated recommendations for enhancement of the stands inspected
