Newest technical black berry variety named Piste (“Faith” in Greek) with colored flesh and juice breeded at Athens Institute of Viticulture (Greece) by researchers Zamanidi P., L. Troshin and P. Radchevskii in 2007 by crossing the Greek varieties Afoos (Mavrodafni x Alicante Boucher) with Ukrainian variety Odessa black (Alicante Bouchet x Cabernet Sauvignon). Duration of production period is 146-155 days. Growth of shoots is strong (2,1-3,0 m). The percentage of productive shoots is more than 90. The yield is very high: 25-30 t / ha. The average weight of clusters is 250 g. It can be characterized by high winter hardiness, drought resistance and increased resistance to fungal diseases in comparison with varieties of Vitis vinifera. Flower is hermaphrodite. Cluster is medium, conical, sometimes with wings, medium density. Berry is small, round, blue-black color with a thick waxy coating. The skin is medium thickness, dense and durable. Pulp and juice are intensely colored. Very high sugar content. Variety is intended for the production of intensely colored dry red wines of excellent class, as well as high-quality sparkling wines, dessert, sweet and liqueur wines; suitable for the manufacture of high-quality strong colored juices. When used in blends with other varieties enhances color, full flavor and enhances the bouquet of the wine
The article presents the biennial data on infestation of
winter barley infected with his disease and pests, depending
on fertilizer rates, the main method of tillage
and plant protection. Weeds are one of the most highly
potent factors that reduce the productivity of plants.
System of agronomic plant cannot increase the productivity
of plants, if it contributes to impurity of crops.
In the studied years, the most common weeds at the
recommended tillage were dead nettle, cleavers,
chickweed, field bindweed. At zero processing - foxtail,
poppy, wild oats, Leptospermum, dead nettle, veronica.
The use of biological and chemical plant protection
products reduced the degree of expansion and
development of disease
Necessity of application of Emistim preparation at various stages of clone micro reproduction is investigated and proved: induction of meristems into culture, micro reproduction itself, education of roots and micro grafting
The article presents results of the evaluation of the
physiological aspects of growth and fruiting of peach
on clonal rootstock VVA-1, depending on the layout
of the trees. It was found that when forming a spindleshaped
crown, the most productive planting scheme is
5,0х1,5 m, at which the most optimized physiological
processes were proved
In the process of scientific and economic experiments on broiler chickens to enhance the physiological and productive effect of growing broiler chickens on grass-soy diets, it is recommended to include the inhibitor of mold “toxins nil” to reduce the risk of aflatoxicosis
Many old varieties of grapes do not meet modern
requirements, so there is a need for improved
assortment of new high-quality varieties. The
translation of the vineyards of the black sea coast of
the Krasnodar region on inoculated culture is not fully
decided the fate of the viticulture of the area. Weak
resistance of American rootstocks to increased content
of calcium and salts in the soil, caused the weakening
of the bushes, reducing the vigor of the shoots, their
maturation and yield of grape plantations in some
areas of the district while reducing their quality
indicators. In this regard, the development of new
high-yielding varieties suitable for own-rooted
viticulture remains the most urgent task for breeders.
The article shows the potential of many years of
breeding work and study of grapes of technical
varieties in Anapa Zone Station, tolerant to phylloxera
and resistant to fungal diseases and frost, with high
quality products and gives a brief description of some
prominent grape varieties
