VARIETY OF MICROORGANISMS GROUPS LIVING ON BERRIES OF GRAPES
DescriptionThe wide variety of microorganisms has been identified in many wine-making countries on the berries of grapes. These are yeasts of different families, forms and kinds, bacterium, mold fungi. In the article, we present the results of investigating species composition of microflora of berries of white and red types of grape, which grows in different economies of the Krasnodar region and the republic of Abkhaziya. The sowings onto the elective media were conducted for the development of entire spectrum of yeast. The grown colonies after preliminary microscoping were separated into the cultures and subjected to testing according to the culturalmorphological signs, being guided by determinants and benefits. It was established the specific variety of microflora on the surface of the berries of grapes of all investigated types, without dependence on the place of their growth. Obtained data showed that the group of yeast, which constantly is present in the complex of the epiphytic microorganisms of grapes of Saccharomyces, Pichia, Hansenula, Hanseniaspora was characteristic for all types of grapes in all investigated regions. The heterogeneity of the taxonometric composition of microflora is shown. Prevailed yeasts were of family Saccharomycetaceae, form Saccharomyces vini. A quantity of yeast of Saccharomyces vini decreases in a number of Myskhako-Caucasus-Fanagoriya, that as a whole will be coordinated with the climatic conditions. Only the type of Pinot nuar grapes had yeasts of Brettanomyces Dekkera. On the berries of Cabernets and Karaburnu we have discovered yeasts of Schisosaccharomyces acidodevoratus, causing acid-reduction. On the berries of the grapes, which grew in joint stock company APF “Fanagoriya” we haven’t revealed the presence of lactic acid bacteria Lactobacillus brevis and yeasts of the form of Schisosaccharomyces acidodevoratus. In the same farm the smallest quantity of yeastswreckers is noted, which we the forms of Pichia and Candida. In the microflora of Cabernets, Risling and, especially, Karaburnu grapes, we have found lactic acid bacteria Lactobacillus plantarum and Lactobacillus brevis. Lactobacillus plantarum. Among the bacteria the total quantity of coccic flora composes - 56 %, the rod-shaped - 44 %. Two types of active acetous bacteria are identified – Acetobacter aceti and Acetobacter xelinum. Especially high was their surface concentration on the berries of Kachich type of grapes

Description
The study was performed to genotype some commercial wine yeast strains using the assay of Interdelta genomic sequences. Experimental parameters of PCR to identify were optimized and optimal simplified method of DNA extraction from dried preparations of yeast cultures was define. Proven method showed a high level of resolution and can be used for the analysis of genetic diversity wine yeast in combination with SSR-markers

Description
In the process of the research we had accomplished an analysis of allelic polymorphism of self-incompatibility in pears in demand in the production and breeding of modern varieties of pears of North-Caucasian Zonal Research Institute of Horticulture and Viticulture collection of genetic resources. In the first stage the consensus primers PycomC1F and PycomC5R were used. With obtained data, after identification of the alleles studied in varieties using consensus primers an allele specific S5 and S8 DNA markers were used for confirming the presence / absence of data allele studied cultivars

Description
This study was aimed on testing of IRAP markers developed at plum on varieties of peach, Russian plum and cherry plum and genotyping of home and foreign varieties of plum, followed by an analysis of the data. During the testing of the markers have been identified as a high level of polymorphism between genotypes of plum and between the studied species. On the basis of the results obtained by genotyping 15 samples of Prunus was built dendrogram. Cluster analysis was divided into 3 groups corresponding varieties of P. persica, P. domestica and a common group for varieties of Russian plum and cherry plum

DescriptionThe results of development of rice breeding lines, carrying the wide range resistance gene to rice blast disease - Pi-40. For identification of the dominant allele of the gene the DNA - marker analysis was used. With co-dominant DNA markers plants from inbred populations that carry a dominant allele of this gene in the homozygous state were selected

Description
The study was aimed on approbation of 11 ISSR DNA-markers for their using in DNA fingerprinting of rare plant species of the Western Caucasus Lilium Caucasicum Miscz. Ex Grossh., Galánthus woronowii Kolak., Pancratium maritimum L. according to results DNA-markers set was selected for further using in the investigation of genetic diversity of the mentioned plant species

APPROBATION OF MICROSATELLITE DNA-MARKERS FOR IDENTIFICATION OF APPLE CLONES
DescriptionAs the result of the work, the test of microsatellite DNA markers for the identification of genomic polymorphism between apple cultivars Florina, Golden Delicious and clonal forms has been done. With the high level of intervarietal polymorphism, studied DNA markers showed no allelic differences between varieties and their clonal forms

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
