THE STUDY OF THE RANGE OF TECHNICAL GRADES OF GRAPES IN THE ALUSHTA VALLEY

abstract 1481904019 issue 148 pp. 142 – 152 30.04.2019 ru 268
The article reveals analysis of varietal and age structure of vineyards occupied by 29 varieties and clones of the technical direction of use in the branch "Alushta" of FSUE "PJSC "Massandra". Taking into account the ecological and climatic conditions of the Alushta valley and the specialization of the economy, the largest share in the assortment of technical varieties is occupied by red grape varieties: Cabernet Sauvignon and clones of Cabernet Sauvignon R5, R8, VCR8, No. 169 including (26.68%), Bastardo Magarachsky and Bastardo clone VCR1 (12.06%), Saperavi (7.33%), Krasnostop zolotovsky (5.69%), Merlot and clone Merlot R3 (4.62 %). White varieties are in a smaller percentage: white Muscat and white Muscat clone R3 (8.47 %), white Kokur (7.1%), Aligote (3.82%), Semillon and clones Semillon № 173 and № 299 (3.68%), Gars level (2.99%). Plantings in the most productive age of 6-10 and 11-15 years are 57.5 % of the total area. At the same time, the share of introduced clones of varieties accounts for 26.65 %. In General, the age structure of the vineyards is acceptable. The company produces high quality wine materials for production of traditional Federal state unitary enterprise "PJSC "Massandra" wines: white Port Alushta, Alushta red Port, pink Port Alushta, Alushta red Table, Pinot Gris, Massandra, Madera Crimean Alushta Tokay, white Muscat, Massandra Kokur, Semillon Alushta and sherry wine. In addition, there are new brands of semi-sweet white and red wines Pearl Massandra, as well as varietal wine materials Aligote, Cabernet, Sauvignon, Merlot, Saperavi, Chardonnay, Bastardo and Semillon. Analysis of the assortment shows that in the production plantings of "Alushta" branch of FSUE "PJSC "Massandra" there are varieties of medium and late ripening, which does not create peaks during harvesting and processing, ensuring uniform flow of raw materials for winemaking. It is necessary to expand the assortment of the economy due to a number of promising varieties of Syrah, Petit Verdot, Malbec, Sangiovese and others with a complex of economically valuable properties introduced from other regions

BIOTECHNOLOGY OF IMPROVEMENT AND PRESERVATION OF NATIVE DON GRAPE VARIETIES

abstract 1541910031 issue 154 pp. 327 – 347 30.12.2019 ru 143
The article presents the results of microclonal reproduction and recovery of native grape varieties, the creation of basic nursery. In addition to the culture of apical meristems, we have developed a chemotherapy using salicylic acid. A method of decontamination of plants from mycoplasma infection has also been developed, which includes the introduction of the antibiotic Cefotaxim in the nutrient environment at a concentration of 50 to 450 mg/L, depending on the degree of infection of plants. Adding to the nutrient medium of the drug Emistim reduces the death of meristems from infection by 3-5 times, improves their differentiation. The use of the drug Melafen helps to improve morphogenesis and quality characteristics of plants. The high survival rate of meristems during adaptation to non-sterile conditions has been noted. Biological testing on herbaceous indicators showed no chronic diseases. Plants after adapting to non-sterile conditions are planted, in the form of vegetative seedlings with a closed rootsystem, on the basic nursery. The survival rate of plants was 70-80%, in some varieties it is higher: 96.4% (Sypun black) - 98.6% (Krestovsky). It has been proved that in vitro clonal microbreeding there is no change at the genetic level even after 8 years of cultivation, which confirms the reliability of the developed technology of reproduction and recovery of native grape varieties in vitro

DETECTED GRAPE VARIETIES OF AFGHANISTAN

abstract 1572003026 issue 157 pp. 346 – 367 31.03.2020 ru 186
The article reports in color on the characteristics of the three varieties and their clones that are common in Afghanistan. In the process of ampelographic screening of vineyards in Afghanistan, three varieties previously undescribed in Russian literature under the local names Aita, Gundyan and Shandyhani were discovered. Their identification by ampelographic and ampelometric characteristics made it possible to establish the original Aita variety, the Gundyan variety as a synonym for Guladan and Shandyhani as a synonym for the world famous Sultanin, or Kishmish. The described varieties are quite common in Afghanistan, reputable in economic returns and are still promising for cultivation in their country, where they are successfully used in the manufacture of dried products and high-quality diet juices. To identify the impact of various environmental conditions on the growth, development, quantity and quality of the crop, these varieties must be tested in all zones of different ecological and geographical areas of cultivation
