In this innovation section there are necessary agrotechnical receptions of care by the vineyard bushes, providing reception of high and qualitative crops of grapes. First of all, these are gartering of sleeves, fruit arrows, vegetating arms; operations with green bodies of a bush, fragmentation, extrapollination, stopping, girdling, stamping, etc., and also mechanization of care works
The leading place among different methods of clone selection of grapes takes the method of professor A.S. Merganian. This method is put the base of modern clone selection which provides a reliable results on practice.
Peculiarities of breeding oidium-resistant genotypes in
crossing Crimea autochthonous grape varieties with
complex interspecific hybrids were studied. Twentytwo
populations consisting of 1323 seedlings were
analyzed over a period of 2008-2014. The highest
oidium resistance was registered in the progeny of the
cross Khersonesskii х ЖС 26-205 (6.8 points), and the
average estimate of oidium resistance across all the
study populations was higher than that of the initial
autochthonous grapes of the Crimea. The level of
hypothetical heterosis in the majority of the study
populations indicates that, on the whole, the hybrid
seedlings possess a higher oidium resistance relative to
the initial Crimea autochthonous grapes. The highest
breeding value was associated with cross combinations
having the complex interspecific hybrids Muscat JIM,
Spartanets Magaracha and Magarach 31-77-10 in their
pedigrees. The cross combination Muscat JIM Ñ…
Shabash was the most efficient, yielding 10.7 per cent
of oidium-resistant seedlings. It was reliably
established that a high level of the genotypically determined inheritance of oidium resistance is found
in crosses with the participation of the interspecific
forms Magarach â„– 31-77-10 and Muscat JIM (female
parents) and Spartanets Magaracha and Tsitronnyi
Magaracha (male parents). The expediency of this
direction of breeding research was proved
The grade of grapes "Academician Eryomin" is introduced in Greece by P.Zamanidi and L.Troshin in 2002 by crossing of Greek Trapsa grade with French Alikant Bush. Duration of production period is 146-155 days. Productivity is very high. The average weight of clusters is 230 gr. It differs by high winter hardiness, drought resistance and raised stability to mushroom illnesses in comparison with grades of Vitis vinifera. The flower is hermaphroditic. Grapes are average size, conic, average density. A berry of average size, roundish, blue-black color, with dense wax touch. A peel is tight. Pulp and juice are intensively painted, with the sort taste. Sugar content is high. Grapes are dried when overripen, concentration of sugars thus reaches 30 and more units. The grade is intended for manufacturing of intensively painted dry red wines of an excellent class, and also high-quality dessert and sweet wines; it is suitable for manufacturing of high-quality juices as well
The newest aromatic wine white berry grape variety Acropolis was breeded by hybridization at the Athens Institute of Viticulture (Likovrisi, Greece) by professors P.Zamanidi and L.Troshinym in 2006 by crossing the Greek variety Kidonitsa with European Riesling. According to the morphological and physiological characteristics it is related to the eco-geographical group of Black Sea. Strong growth of shoots (2,1-3,0 m). Degree of ripening vines is very high: over the entire length, except for the top. Length of production period 146-155 days. High yield 25-30 t / ha. Average weight of cluster is 360 g. Characterized by high resistance to cold, drought and increased resistance to fungal diseases in comparison with common varieties of Vitis vinifera L. Flower is androgynous. Bunch is medium, conical, medium density. Berry is medium, spherical, greenish-yellow color with a thick waxy coating. Cuticle of medium thickness, dense, durable. Pulp and juice are with pronounced varietal type taste of Riesling. Sugar content is very high: up to 24% more. Bunches of variety Acropolis continuously stored in the bushes. Variety is intended for manufacturing dry white wines of excellent grade and high-quality sparkling wines, dessert and sweet wines, suitable for production of high quality aromatic juices
Newest aromatic white berry wine grape variety Agapi was breeded by hybridization at the Athens Institute of Viticulture (Likovrisi, Greece) by professors P.Zamanidi, L.Troshin and P.Radchevskiy in 2006 by crossing the Greek varieties Afiri white with central European variety Traminer pink. Strong growth of shoots (2,1-3,0 m). Level of ripening vines is very high: over the entire length except the top. Length of production period 146-155 days. Productivity is very high: 25-30 t / ha. Average weight of cluster 300 g. Characterized by a high resistance to cold, drought and increased resistance to fungal diseases compared to varieties of Vitis vinifera L. Flower is androgynous. Bunch is medium, conical, medium density. Berry is medium, short elliptical or spherical, greenish-yellow in color, with a thick waxy coating. Cuticle of medium thickness, dense, and durable. Pulp and juice are with pronounced varietal flavor, similar to the aroma of Traminer pink. The sugar content is very high, more than 24%. Clusters of Agapi variety regardless of autumn weather conditions persist for a long time in the bushes. Variety intended for the manufacturing dry white wines of excellent grade and high-quality sparkling wines, dessert and sweet wines; suitable for production of high quality fragrant juices
The article presents the results of the studies of 11
varieties cultivated in the eastern region of South Coast
wine-growing zone of Crimea (planting of
"Solnechnaja Dolina ", near Sudak mountain) in the
area of their natural growing, where was formed the
gene pool of grapes for a long time. As a result, the
three-year (2010-2012) study found that the majority
of indigenous varieties had small number of fruitbearing
shoots in the bush: the varieties with colored
berry - 53,3-73,3%, in white-berry - 46,6-75,9% except
Shabash variety - 79.9%. We have identified the most
productive varieties which were Dzhevat kara (62.2 t /
ha), Kokur Beliy (48.9 t / ha), Kapselsky Beliy (44.4 t /
ha), and varieties with female type of flower: Kefesiya,
Ekim kara, Kock pandas, Sary pandas and Crona gave
not high yield: 22.2; 22.2; 24.4; 28.9 and 28.9 t / ha.
On the strength of growth, productivity and the
accumulation of sugars in the juice of berries, we
picked out varieties of Dzhevat kara, Crona, Kapselsky
beliy. According to the main economic indicators, it
turned out that the most profitable varieties are
Dzhevat Kara, Kokur beliy and Kapselsky beliy.
Hence, these varieties in conditions of the Crimea have
much greater prospect of reproduction and
development of production
The article presents a study on agro-biological and technological indicators of Don indigenous wine grapes in the conditions of the Anapa-Taman area of the viticulture of the Krasnodar region. It was found that the introduced varieties are consistent with the conditions of the area and can be recommended for growing in production plantations in southern Russia. On ripening, the varieties are as follows: the early ripening varieties are Sibirkovy; a group of middle-ripening - Aligote, Plechistik, Varyushkin; to the medium-late - Bessergenevsky 10 and Krasnostop Anapsky. Highest yield was proved to for such grape varieties as Bessergenevsky 10 (150 kg / ha) and Varyushkin (140 kg / ha). Test grapes of Aligoté and Krasnostop Anapsky showed an average yield of 120 and 130 kg / ha, respectively, red and Sibirkovy Plechistik - 140 and 135 kg / ha. Comparing the current literature with the results, we noted the following notable differences: all the studied indigenous wine grapes in the conditions of the Anapa-Taman area of the Krasnodar region matured earlier, had higher productivity indexes and gave higher yields, than in the conditions of their homeland Rostov region
The article provides an overview of the results of the research of non-root treatment of bushes with activated water with the features of BAS. We have found that activated water, charged with the "Akvator" device through the BAS matrix has the property of impact on plant and the efficiency exceeds impact of BAS solutions themselves
