The Patris variety is a hybrid, which was made as the result of Greece-Russian scientific collaboration in Greece by Panteley Zamanidi and Leonid Troshin in 2001 year by hybridization of Aigeorgitiko and Cabernet Sauvignon variety. By its morphological characteristics, it is included to the group of the Black sea varieties (convar. pontica subconvar. balcanica Negr.). The production period is 156-165 days. The growth of shoots is big. The yield is very high. The weight of bunch is 250 g. It has good frost resistance, drought resistance and higher steadiness to mushroom diseases, comparing with the parents varieties of Vitis vinifera L. The leave is middle, black-green, five lobes, deep divided, bubbles on the higher plate are low, the hairs are low on the upper side and intense on the bottom. The flower is hermaphrodite. The bunch is middle, cylinder conical or wrinkle, low density. The berry is middle, round, blue-black color. The skin is dense. The pulp is juicy with paslen taste. The sugariness of juice is high. The variety is used for making dry red wines of outstanding quality
The history of the spread of patisson on the example of agro-botanical illustration has been reviewed . The different forms of selected, dissemination and use in the modern world investigated
The results of the experimental studies are published, according to which the influence of dense forest belts on wind regimen and moisture storage of agroland-scapes is defined by phytomass of the stand
Results of research of influence of foliar top dressings by Zitovit and Zircon preparations on development of plants of grape of Berlandieri × Riparia Kober 5Ð’Ð’ grade on sandy soils are submitted. Processing of plants with Zitovit in conditions of their insufficient mineral nutrition through roots, improved their growth and development. Action of Zircon preparation for raising immunity promoted qualitative rearrangement of morphological parameters of development of plants
Sorghum is cultivated in many countries of the world
on around 50 ml hectares. The main producers of
sorghum are India, Nigeria, Sudan and the USA.
Sorghum comes from equatorial Africa. India and
China are the secondary places of origin and formation.
The USA achieved great success in breeding, seedgrowing
and agro technologies of grain sorghum. In the
country sorghum occupies 14.4% of the world amount
of sowing areas; the gross yield is 40%. Sorghum
breeding on Don was started by E.S. Yakushevsky in
1938. In 1963 after a long break the work was restarted
at the Zernograd Breeding Station headed by Ya.I.
Issakov. At present the amount of sowing areas for
sorghum is constantly increasing in RF (220.3 thousand
ha in 2015). It occurs due to aridity of climate and more
frequent use of the crop as insurance. Besides, the
development of white kernel varieties gave an
opportunity to use sorghum for starch and spirit. There
are 221 varieties and hybrids of sorghum registered in
the State List. The main directions of breeding work
with grain sorghum are early maturity, suitability for
mechanical harvesting, productivity and grain quality.
The ARRIGC developed the white kernel early
maturing varieties ‘Velikan’, ‘Zernogradskoe 88’,
‘Ataman’ without necessity to be dried after harvesting,
with productivity of 8 t/ha. The main directions of breeding work with sweet sorghum are early maturity,
high intensity of initial growth, low height, resistance to
lodging, high productivity and quality of green chop.
The ARRIGC developed the varieties for fodder use
(‘Listvenit’), for spirit and treacle (‘Debyut’ and
‘Zernogradsky Yantar’). Sorghum due to origin and
varietal diversity even in dry and hot parts of the world
allow obtaining stable, high yields of grain and green
chop. This makes sorghum the leading grain-forage and
food crop
In the article, the main issues of development of perennial cereals (morphology, phenology, formation of buds, physiology, biochemistry and research methods) are discussed. Peculiarities of regulation of development and the character of their evolution are considered. Problems of evolution of the cereals with widespread use of the data of Russian and foreign authors are discussed
We developed an effective technology of reproduction in meat cattle breeding, which allows rational use of the bulls-producers, to obtain a high output calves (85-95%), to organize the accuracy of the account of the origin of young animals, to improve the level of selection-breeding work on the improvement of productive and breeding qualities of animals and create in a shorter time highly productive herds of meat cattle
We have studied survival and regeneration rate of raspberries and blackberries buds when introducing into cultivation in vitro during October. The rate was significantly higher for buds taken in October than that for ones taken in February. At the first stage of
micropropagation, for the most of studied varieties of raspberries, cultivation on nutrient medium contained BAP (0.5 mg/l) and GA (0.2 mg/l) was most successful; for blackberries, increasing concentration of hormones (BAP to 1.0 mg/l and GA to 0.5 mg/l) was better
Diagnosis by PCR-RFLP (polymerase chain reaction –
polymorphism of the lengths of restriction fragments)
is the standard analysis of point mutations for the
diagnosis of allelic polymorphism of candidate genes
related with productive qualities of farm animals.
Along the length of the fragments (RFLP) make a
conclusion about the absence or presence of the point
mutation, and homozygosity or heterozygosity of the
individual. The aim of our work was the optimization
of protocols for conducting PCR-RFLP analysis for
genotyping sheep for genes of the growth hormone
gene differential growth factor and gene of calpastatin
The method of optimization of the process of delivery of the mineral fertilizers to agricultural consumers are given on an example of farms of Egorlyk district of the Rostov region
