THE STUDY OF THE RANGE OF TECHNICAL GRADES OF GRAPES IN THE ALUSHTA VALLEY
Description
The analysis of varietal and age structure of vineyards occupied by 29 varieties and clones of the technical direction of use in the "Alushta" branch 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 favorable. 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

06.00.00 Agricultural sciences
Description
The article gives the results of the three years of research to identify the main species composition of fungal pathogens when stratified open and closed methods. Biological efficiency of Guapsin, 0,2%, and Trichodermin, 0,5% is shown. During the period of stratification, using an open method "on the water", the following pathogens have evolved: Cladosporium herbarum (18,6%), Trichotecium roseum (16,3%), Phomopsis viticola (13,9%), Alternaria spp. (13,4%), Penicillium sp. ( 9,1%), Aspergillus sp. (5,6%), Pythium sp. (4,3%), Gonatobotrys flava (4,3%), Mycelia sterilia (2,8%), Botrytis cinerea (2,2%). The studies found that the close method of stratification in the peat developed the following specific composition of pathogens: Penicillium spp. (21,1%), Phomopsis viticola (16,4%), Botrytis cinerea (15,3%), Trichotecium roseum (11,1%), Alternaria spp. (8,2%), Mycelia sterilia (1,0%). During the period of stratification, biological efficiency Guapsin, 0.2%, and Trichodermin, 0,5%, was 31,9-88,0% and 28,2-86,3%, respectively
