FORECASTING OF GRAPE YIELD AND THE ESTABLISHMENT OF OPTIMUM BUSH LOADING DURING THE CUTTING IN BUDS ON THE PROPOSED YIELD ON THE EXAMPLE OF OAO AF «SOUTH»

abstract 1161602026 issue 116 pp. 352 – 368 29.02.2016 ru 801
The article presents the material of forecasting for grape yield of next year and establishing the optimal loading if cutting of bushes. The material includes 14 varieties of grapes, 11 of them are technical and 3 are table ones. For each year of stable high yield of grapes, it is necessary to pre-set the optimum length of fruit cutting of shoots and optimum load on the bush healthy eyes. To do this for each variety on the eve of trimming bushes we perform optimum productivity analysis of wintering buds of fruit along the length of shoots, i.e. we implement forecasting of grape yield for next year. We have a plan of forecasting for yields of vineyards by microscopy of wintering buds on one-year shoots of fruit ripened grapes in order to establish the potential of embryonic establishment of inflorescences in the central holes of buds. Based on the analysis of buds, the indices were calculated for wintering fruiting buds and their degree of damage during the growing season. It was revealed, that the majority of grape varieties under study shows high tab embryonic inflorescences in central buds in overwintering buds for next year yield. Higher rates at a rate of fruiting buds were wintering in the varieties: Moldova (section 27). - 1.66; Bianca (section 6). - 1.83; Kunlean (section 15). - 1.71; Merlot (section 14). - 1.64; Saperavi (section 56). - 1.76. The lowest rates of fructification - the varieties Muscat Hamburg (section 21) and Augustine (section 11) and were respectively 1.20 and 1.24. As a planned productivity, we offered the optimal loading model of cutting bushes buds. As a result of productivity analyzes of buds along the length of the fruit shoots in 2016 we recommended to carry out pruning of fruit annual shoots 3-4 buds of the form of AZOS-1 and the form of cordon - 5-6 buds

OENOLOGY AND BIOCHEMISTRY OF MERLOT VARIETY AND ITS CLONES IN DIFFERENT ZONES OF GROWTH

abstract 1291705083 issue 129 pp. 1140 – 1157 31.05.2017 ru 789
The article presents results of studying the oenology and the biochemistry of the Cabernet-Sauvignon grapes in different areas of the Krasnodar region - Taman, Anapa, Abrau-Dyurso, Gelendzhik and Krasnodar. The yields, the mechanical composition of the grapes, the biochemical indicators of the juice of berries were compared. The cultivation zone affects the yield, the average mass of the bunch, the number and mass of berries in the bunch, the mass of the crest, but according to the percentage of berries and crest in the bunch, the bunch structure (ratio of mass of berries to mass of the ridge) does not significantly differ between growing zones. The mass of 100 berries and 100 seeds, the weight of seeds in 100 berries, the clustering index (the ratio of pulp with juice to peel) can differ in different places of growth, but with insignificant coefficients of variation. The composition of the bunch as a percentage of the total mass varies little over the growing zones: the ridges make up 5.6- 5.7%, the skin 4.9-5.2%, the seeds 4.8-4.9%, the pulp with the juice - 84.3-84.5%. Structural and berry indicators varied in the range of 5.4-5.5 and 76.84, respectively. Depending on the place of cultivation, the yield of the grape must in laboratory conditions was 75.1-75.7%. Analysis of the structure, composition and the structure of bunches showed that the mechanical composition of Cabernet-Sauvignon refers to the first group of varieties that retain their valuable characteristics when changing the growing conditions. When harvesting, the mass concentration of sugars was 19-19.8%, titrated acidity - 8.1-9.2 g / dm3, pH - 3.3- 3.4. Depending on the place of cultivation of the content of organic acids in the juice of berries was: wine - 4917-5918 mg / dm3, apple - 1926-2763, lemon - 215-416 mg / dm3. In different places of cultivation in% of the total amount of organic acids studied, the content of tartaric acid varied from 61.7 to 71.4%, apple - from 24.7 to 33.3%, lemon - from 3 to 5%. Thus, the content of organic acids in the juice of Cabernet-Sauvignon berries depends on the specific growing conditions. Depending on the growing places, the mass concentration of potassium cations is 2630-3508 mg / dm3, sodium 162-436, magnesium 171-230, calcium 185-255 mg / dm3. However, in most cases, as a percentage of the total cation content, there are no differences depending on the site of growth. Thus, the biochemical parameters of the juice of CabernetSauvignon berries depend on the specific natural conditions of the terrain and, according to these parameters, the variety belongs to the second group of varieties with less plasticity to different growing conditions

THE USE OF MOLECULAR BREEDING METHODS RESISTANCE TO NET BLOTCH OF BARLEY (REVIEW)

abstract 1131509093 issue 113 pp. 1315 – 1325 30.11.2015 ru 786
In recent years, due to the increasing aridity there was an increase in the frequency of epiphytoties leaf disease of barley. Therefore, we can see now how greatly increased the need for the creation of resistant grades. Introduction of the selection marker will significantly speed up the breeding process for resistance to pathogens. Employees of the All-Russian Institute of Plant Protection recommended three genes - Rpt 1b, Rpt 5, Rpt 6 to control the resistance to the pathogen Pyrenophora teres for use in breeding programs in the North Caucasus. Rpt 5 gene is one of the most efficient one, because it determines the resistance to the eight isolates of the fungus Pyrenophora teres of different origin. In 2011, Australian scientists have discovered microsatellite markers called Bmag0173 and HVM74, closely linked to the gene Rpt5, which are used very effectively in order to marker-assisted selection of resistant grades in Australia and Canada. Due to the urgency of creating new genotypes carrying resistance genes to net blotch, that would be effective in the Southern Federal Region, the staff of All-Russian Scientific-research institute of Grain Crops after I.G. Kalinenko and the All-Russian Research Institute of Plant after N.I. Vavilov has developed a practical strategy for the use of molecular techniques to create barley grades resistant to this pathogen, which is being successfully implemented

abstract 1141510054 issue 114 pp. 711 – 719 30.12.2015 ru 775
Based on the analysis of the nature of some flowering test crosses which have been resulted in the hybridization with purposely chosen sterile sources (analyzers), the new self - pollinated lines of maize have been identified according to the content of fertility-restorer genes of ‘C’ type of CMS. Genotype of the line RD 257 - rf4rf4rf5rf5Ff6Rf6 (class II), genotype of the line RD 245 - rf4 rf4 Rf5 Rf5 rf6 rf6 (class III), genotype of the line RD 274 - rf4rf4Rf5Rf5Rf6Rf6 (class V), genotype of the line RD 231 - Rf4Rf4rf5rf5Rf6Rf6 (class VI ) genotype of the line RD 261 - Rf4Rf4Rf5Rf5Rf6Rf6 (class VII). The identification of the content of the alleles of fertility - restorer genes allows forecasting the nature of flowering hybrid progeny resulted in the hybridization with a known genotype. We have created a catalog of self - pollinated lines of maize according to the fertilityrestorer genes, which consists of 18 lines, which have been studied in all the years of research. We have identified the lines belonging to classes I, II, III, V, VI, VII and VIII. During the transfer of maize hybrids on a sterile basis the lines of classes I and VIII are those ones which have been of great interest. The self - pollinated lines KV 204, SP 286 (class I) are the reliable fixers of «C» type of CMS. The progeny resulted in the hybridization with any sterile lines is characterized by complete sterility. The new self - pollinated lines KV 498, KV 272, KV 227, SP 357, RD 261 (class VIII) are constant natural fertility-restorers. They are able to fully restore fertility in hybridization with any sterile lines and in any growing conditions

CHARACTERISTICS OF SUNFLOWER OPEN-POLLINATED VARIETIES FOR MAIN SEED TRAITS

abstract 1181604082 issue 118 pp. 1282 – 1292 29.04.2016 ru 773
Development of confectionery sunflower openpollinated varieties (OP-varieties) is a prospect direction in sunflower breeding. High price level for confectionery sunflower seeds pushes forward the breeding program. Contrary, it is necessary to offer product, meeting consumer’s expectation for large seeds, good dehulling rate, proper oil and husk content. The aim of our work is to study morphometric peculiarities of seed structure for sunflower OP-varieties of different types – oil and confectionery, and to identify the best samples for using in the breeding program as an initial material. The study was done at All-Russia Oil Crops Research Institute (VNIIMK) named by V.S. Pustovoit (Krasnodar) in 2014 and 2015. Seeds of 6 OP sunflower varieties of VNIIMK breeding were used as a material (confectionery type – Dzhinn, SPK, Lakomka, Oreshek, Borodinskiy and oil-type – Muster). OP-varieties were sown by randomized blocks with 3 replications. Every plot had 4 rows. It was shown that seeds of confectionery sunflower OP-varieties had higher values of main traits (length, width and thickness) in comparison with oil-type sunflower. Seed traits analyses allowed identifying the best confectionery samples (Dzhinn and Oreshek) for future breeding
