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.
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.
Results of researches carried out in stationary multi factorial experience, plotted in 1991, were generalized in the article. Different influence of cultivated crops
in crop rotation on agro physical properties of active fertile layer of old irrigated leached chernozem
was determined on the base of material generalization.
Positive role of alfalfa for improvement of agro
Physical soil properties were revealed. Quantity of agronomically valuable aggregates and water proof
of soil structure are increased because of it.
Data of many year researches on influence of cultivation methods ( main soil cultivation, fertilizers, irrigation methods) on physicochemical properties
of common black soil, growth, development, crop productivity, their economical and energetic effectiveness in the conditions of arid steppe zone
of Rostov region were positioned in the article.
Eight-year research data of crop rotation of new
six-field crop rotations and energy-saving methods
of their cultivation are presented in the article. More productive grass- grain ploughing crop rotation and energy-saving means of main soil cultivation, rates
of fertilizers and regime of irrigation, increasing productivity of agricultural lands, keeping fertility
and biodiversity of irrigated agro landscapes were revealed.
