The purpose of the study was to examine a century of
experience of growing of forest cultures of the
Siberian stone pine in forest conditions in the region of
the Middle Volga. To achieve these objectives, we
have investigated old growth culture of Siberian stone
pine in the conditions of fresh oak forests in the
territory of Rootka forestry of the Mari El Republic.
Culture of Siberian stone pine was planted after
continuous tillage. The distance between rows was 2,5
m, step landing – 1,0 m. The site was divided into five
options, depending on variations in the width of
planting strip (I-48 m, II-44 m, in III-40 m, IV - 36 m,
V - 32 m). The studies have shown that the Siberian
stone pine trees, regardless of the variant, are
characterized by good clean ability from twigs, which increases with decreasing of the width of the curtain. It
can be noted that in the 100-year-old age, the average
height of trees reaches of 28,7 m, an average diameter
of 49,8 cm. Stock of forest reaches 795,3 m3
/ha. Best
annual increase is observed in growing cultures of
cedar in the wings with a width of 40 m and is 7,95-of
7,93 m3
/ha. Based оn the research, we have concluded
that Siberian stone pine should be recommended for
introduction into the zone of coniferous-broadleaved
forests of the Middle Volga region. When creating
crops, it is necessary to use larger seedlings and plant
density is not more than 1,0 thousand pieces/ha, and
the width of the planting strip shall be not less than
40,0 m.

There was studied the influence of factors of the medium on rice plants and hybrids of the first generation in the vegetation experience on the conditions of the artificial climate camera (ACC) and on the vegetation plot (control). There was determined the individual reaction of varieties on the conditions in ACC. There were revealed the modified changes at rice plants by a range
of features. There was made a conclusion on necessity of preliminary study of varieties in ACC before their introduction into hybridization
The analysis of frequency and distribution of chiasma of interspecific tomato F1 hybrids at meiosis prophase I was given. The character of synapsis in anther mother cells of interspecific tomato F1 hybrids was determined; the number of distal and interstitial chiasmata was calculated. The samples, recommended for their inclusion into the selection process as the inducer of genetic variability were chosen
The researchers of the institute are studying adaptive power of 17 varieties and 6 lines of winter wheat sown after peas using various methods of assessment of their adaptive properties. During the years of study (2012-2014) we found out that environmental conditions which account for 78% have the greatest effect on the trait ‘grain productivity’ in the formation of the yield. The share of genes accounts for 9,7%, the specific correlation ‘geno type x environment’ accounts for 10% which allow calculating adaptive properties. It has been defined that productivity of winter soft wheat changed a lot due to growing conditions and characteristics of varieties. The productivity ranged from 38,7 c/ha (‘Garant’ in 2014) to 76,5 c/ha 9’Lilit’ in 2013). The study found out that the varieties ‘Stanichnaya’, ‘Asket’ and ‘Lilit’ possess the highest response to cultivation with bi=1,15; bi=1,18 and bi=1,25 respectively. The varieties ‘Lilit’, ‘Krasa Dona’, the lines ‘430/07’, ‘260/09’ and 771/09’ possess a high adaptive ability and productivity with 111%, 105%, 108%, 105% and 106% respectively. The study of adaptive properties of winter soft wheat varieties gives an opportunity to distinguish adaptive, stress tolerant varieties with plasticity according to the primary structural elements which form productivity. The varieties ‘Asket’ and ‘Lidiya’ are characterized with high response to cultivation in different environmental conditions. The varieties ‘Lidiya’ and ‘Kapitan’ belong to adaptive cultivars. The varieties ‘Kapitan’, ‘Krasa Dona’ and the line ‘234/07’ are stress tolerant according to the trait ‘grain productivity’; the varieties ‘Kapitan’, ‘Krasa Dona’, ‘Lilit’ and the line ‘771/09’ are stress tolerant according to the trait ‘number of seeds per a ear’; the varieties ‘Lilit’, ‘Krasa Dona’ and the line ‘771/09’ are stress tolerant according to the trait ‘weight of seeds per a ear’
Development of confectionery sunflower openpollinated
varieties (OP-varieties) is a prospect
direction in sunflower breeding. High price level
for confectionery sunflower seeds pushes forward
the breeding program. Contrary, it is necessary to
offer product, meeting consumer’s expectation for
large seeds, good dehulling rate, proper oil and
husk content. The aim of our work is to study
morphometric peculiarities of seed structure for
sunflower OP-varieties of different types – oil and
confectionery, and to identify the best samples for
using in the breeding program as an initial material.
The study was done at All-Russia Oil Crops
Research Institute (VNIIMK) named by V.S.
Pustovoit (Krasnodar) in 2014 and 2015. Seeds of
6 OP sunflower varieties of VNIIMK breeding
were used as a material (confectionery type –
Dzhinn, SPK, Lakomka, Oreshek, Borodinskiy and
oil-type – Muster). OP-varieties were sown by
randomized blocks with 3 replications. Every plot
had 4 rows. It was shown that seeds of
confectionery sunflower OP-varieties had higher
values of main traits (length, width and thickness)
in comparison with oil-type sunflower. Seed traits
analyses allowed identifying the best confectionery
samples (Dzhinn and Oreshek) for future breeding
In article the review of results of studying plant growth and development of maize, as well as features of the formation productivity of mid-season hybrid of corn Valentin depending on the variant of primary tillage (in common Harnes with Luvaram and Titus with Harmony) under conditions of sufficient moisture zone of the Central Ciscaucasia is given.
Tasting and smoking properties of tobacco products
depend on chemical composition of dried tobacco. The
most important are nicotine, carbohydrates, and
proteins. Their content is controlled when new sorts
are bred. In the article data on chemical composition
and their analysis for some hybrids, new and zoned
sorts are presented. Most of studied samples had
medium nicotine content in dried tobacco. Hybrid of
Jubileiniy noviy 142 and Ostrolist 46, sorts: Trapezond
159, 359, 115 and Ostrolist 46 were characterized as
low nicotine tobaccos. Jubileiniy (standard) and
Oktiabrskii were characterized as high nicotine
tobaccos. This indicator depends on rain quantity
during vegetation period. During drought seasons this
indicator is higher. Total soluble carbohydrates content
affects smoke taste. The more water soluble
carbohydrates content the better smoking properties
tobacco has. Unlike nicotine, carbohydrates content
when rainy season increases. Best results were for
Krupnolistniy 9M and Oktiabrskii. Proteins have
negative effect on smoke taste as it becomes bitter and
with smell of burned feathers. Most of studied hybrids
have quite high protein content. For cured tobacco
quality assessment, not total contents of proteins and
carbohydrates are important but their ratio
(carbohydrates/proteins) called Shmuk ratio. Best
results were for Krupnolistniy 9M and Oktiabrskii
This article presents the results of the chick peas use instead of sunflower cake, in feeding young and adult livestock hens-layers of the cross "Hajseks brown". The researches were carried out in the JSC "Agrofirm Vostok" of the Nikolayevskiy district in the Volgograd region. The sunflower cake replacement with legumes - chickpeas as the part of the experimental animal fodder for young and adult livestock hens-layers had a positive influence on productivity, physiological state of the birds, product quality and economic performance. Chick peas’ use in young hens feeding improves live weight at 1.03-4.68%, egg production in 0.99-4.7%, the average weight in 0.99-3.75% and eggs quality indicators. Morphological and biochemical indices in experimental young hens and laying hens in all the groups were within the physiological range, indicating normally occurring redox processes in the body of a bird. However, the chick peas’ application in fodder for experimental young hens and laying hens contributed to the increase of total protein, calcium, phosphorus content in serum compared with counterparts in the control group that received sunflower cake. As the researches result, the economic effect in the experimental groups was 833.01-3821.87 rubles
This article presents the results of the chickpea effect in feeding young and adult laying hens of "Hajseks brown" cross on their productivity and nutrient digestibility of feed. Studies have been conducted on the JSC "Agro-firm Vostok" in Nikolayevsky district of the Volgograd region. Complete or partial replacement of sunflower oil cake by chickpeas as part of feed for the experimental pullet hens improves nutrient digestibility coefficients compared with the control pullet group. The balance of nitrogen was positive in all groups, the use of nitrogen taken from guinea pullets was higher than in the control group at 0, 27-0,74%. Use of chickpea in the composition of feed for laying hens increases the digestibility coefficients of nutrients: dry matter - to 1,17-3,25%, organic matter - to 1,62-3,37% crude protein - to 0,45-1, 77%, crude fiber - to 0,72-1,05%; crude fat - to 0,35-1,55%, compared with chickens, hens in the control group. The use of nitrogen from the digested was1,37-2,13% higher in the experimental groups compared to analogs of the control group. The use of calcium and phosphorus for the formation of eggs was also higher in the experimental groups
