In the article the color photos of 111 temporarily allowed grades of grapes having outstanding characteristics, basically, for their effective use in amateur winegrowing of Russia are presented. They are actively involved by selectors as initial forms
Step by step results of many year researches of clonal selection of grape varieties: Clairette white, Saperavi, Sauvignon white and Chardonnay, growing in the Ltd company “ Pobeda” of Temryk district of Krasnodar region are cited in the article. Highly productive
proto clones were selected. Clairette white
is the best one as a variety from them and it was
given to the state experiment under the name
Clairette temryk.
The Dimitra variety is a hybrid, which was made as the result of Greek and Russian scientific collaboration in Greece, by Pantiley Zamanidi and Leonid Troshin in 2001 by hybridization of Aigeogritiko variety and Merlot. On its morphological characteristics it is included in the group of the Black sea varieties (convar. pontica subconvar. balcanica Negr.). The production period is 146-155 days. The leave is middle or big, black-green, five lobes, deep dissected. The middle weight of bunch is 300 g, the form is cylinder conical, middle density or friable. The berry is middle, not colored, with low labrusk taste. The yield is high. The sugariness is high. The quantity of seed in the berry is one or two. It has higher frost resistance; drought resistance and higher steadiness to mushroom diseases compare with the parents varieties. The variety is using for making desert dry red wine of outstanding quality
Results of the fifth International Conference
(KubSAU,2007) on problems of vintage,
characteristics and storage of perishing wild
and native grape of the North Caucasus and
the Black Sea area regions are dealt with
in the review article. Results of the work of Eurasian countries scientists for the last two years fulfilling
the project of International institute of genetic plant resources Biodiversity International have been cited.
In particular, assessment of wild grape in the places of its initial origin was carried out, world gene pool was enriched on three hundred patterns, methods of molecular marking of grape genotypes and ampelographic screening of two subspecies Vitis Vinifera L. were improved, international data bank was created and variant of regional ampelography was written.
In this article 59 color photos and short characteristics of perspective native domestic varieties of grapes from 104 growing in National Ampelographical Collection of Russia (Anapsky area of Krasnodar region) are presented. These grades are national property of our state. Our aim is to find, collect and save 152 grades described in official ampelographical editions, but not shown in NACR
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
Zoned assortment of grape plantings of Russia, 170 grades for today, by their ten years' estimations by production workers and assortment researchers, as well as in other wine growing countries, it is divided into three ampelographical groups: recommended or zoned, resolved (perspective and duplicated) and temporarily resolved. It allows to be guided easily to practical workers of wine growing sub-division in the point of selection of the necessary grades and the organization of optimum industrial ampelocenoseums of any scale
In the article color photos of grades of grapes in the North Caucasus are resulted: all of 138 zoned, i.e. recommended grades for cultivation in the south of the Russian Federation. Grades are photographed directly on the bushes in a full maturity of berries that allows user to receive the visual information on features of a complex generative and vegetative sphere of plants and marker signs for definition of their true names or an establishment of synonyms
Effects of different levels of vitamins (thiamine, pyridoxine and nicotinic acid) and macro-elements (MS, NN and PG) on development of globular, heart- and torpedo-stage embryos and plantlets with green cotyledons and on shoot production from them were studied in grapevine interspecific hybrids: cvs. ‘Bianca’, ‘Podarok Magaracha’ and ‘Intervitis Magaracha’. Pro-embryogenic calli were derived from petiole explants on solid full-strength NN medium supplemented with different levels of 2,4-dichlorophenoxyacetic acid (2,4-D) and 6-benzyladenine (BA) for each cultivar and used to initiate cell suspensions in liquid NN medium supplemented with 1 mg L-1 2,4-D and 0.2 mg L-1 BA. The following formulations of media were optimal for different stages of somatic embryogenesis and for plantlets with green cotyledons development: liquid NN medium supplemented with 0.5 mg L-1 BA for globular embryo formation; liquid HTE medium (with PG macro-elements, thiamine and pyridoxine at 5 mg L-1 each and 0.5 mg L-1 nicotinic acid): supplemented with 0.2 mg L-1 BA for heart-stage embryo development, supplemented with 0.1 mg L-1 indole-3-acetic acid (IAA) and 30 mg L-1 sodium humate for torpedo-stage embryo development and supplemented with 0.5 mg L-1 gibberellic acid (GA3) for the growth of plantlets with green cotyledons. Solid MS medium modified by the addition of nicotinic acid, pyridoxine and p-aminobenzoic acid (PAB) at 5 mg L-1 each, 0.5 mg L-1 thiamine and 0.5 mg L-1 BA was best efficient for shoot production from plantlets. Inflorescence formation in regenerated plants of cv. ‘Podarok Magaracha’ grown on solid hormone-free PG medium was induced by addition of nicotinic acid, pyridoxine and PAB at 5 mg L-1 each, 0.5 mg L-1 thiamine and 0.2 mg L-1 BA into liquid modified HTE medium for growth of plantlets with green cotyledons and into solid modified MS medium for shoot production from them.
“Professor Elena Zakharova” variety is a hybrid between Aigeorgitico and Cabernet Fran, which was made in the result Greek-Russian creative scientific cooperation. The period of production is 156-165 days. The growth of arms is fast. The degree of ripening is higher. The percent of fruitful arms is more than 90. The yield is high. The average weight of cluster is 260 g. It has high resistance to cold, drought-resistance and higher resistance to mushroom diseases. The leave is average, symmetrical, average parted, five lobes. There are two inflorescences on one arms - 4 and 6 on the nodes. The flower is hermaphroditic. The cluster is middle, cylindroconical, middle density. The berry is middle, round, blue-black color. The pulp is juicy, with solanaceous taste. The sugar content is high. This variety is developed for producing dry red wines of perfect quality
