The article discusses the hybridological analysis of the
inheritance of plant resistance of winter wheat to
brown rust Putignano. For this purpose, we performed
the analysis on the varieties of wheat of local selection,
studied immunological reaction to R. triticina in
connection with the types of wheat resistance to leaf
rust pathogen. In the work, we considered the different
immunological parameters (type of plant response to
the introduction of the pathogen, the intensity of
infection of plants, the size of urediniospores, the
number of urediniospores in one urediniomycetes, the
amount of time from the time of inoculation until the
beginning of the first urediniomycetes (i.e. a measure
of latent period) and the area under the curve of
disease development). Study of the inheritance of the
type of plant responses to the introduction of the
pathogen by the method of hybridological analysis
revealed that this immunological reaction can be
controlled by both dominant and recessive genes.
Monogenic control of resistance in our study was
fairly uncommon and installed from THERE 200
varieties and Purdue 5396. It is shown that the
majority of the examined lines type of plant response
to the introduction of the leaf rust pathogen is
controlled, as a rule, several genes with different types
of interaction. The results of hybridological analysis
allow to draw a conclusion about what type of plant
response to the introduction of the parasite – an
integral indicator that takes into account the
morphological peculiarities of urediniomycetes (the
size and number of urediniospores produced in them)
This article is devoted to studying the influence of
conditions of keeping and feedings on broilers of Hubbard
RedBro cross, and the quality of the received
products in case of application of floor and cellular
content in the conditions of a farm. It was found that
when receiving a feed of its own production with the
use of feed ingredients grown in farms without pesticides,
recorded a statistically significant reduction in
the potentially dangerous health animal substances. As
compared with a factory forage therein reduced pesticide
content by 14 times, mercury and arsenic is 24
times, 5 times cadmium, lead 10 times. Results of
studying of economic indicators of cultivation of
broilers of cross Hubbard RedBro and also chemical
composition and quality of carcasses demonstrated that
the essential difference between a floor and cellular
condition of keeping is not established, however use of
a diet on the basis of what forages promoted statistically
reliable decrease in concentration of toxic metals in
muscles of a bird of experienced groups. As a result it
was found that use of the researched compound feed in
diets of broilers raised indicators of biosafety and provided
ecologically safe (“organic”) meat products of
poultry farming
In order to reduce the impact of stress factors on the
body of pigs, new technologies and efficient
veterinary and preventive measures in breeding and
cultivation are being developed. The results of our
scientific and economic experiments found that the use
in daily diets of pregnant and lactating sows according
to our schemes of biological additives (to finish /
day.): Laktobifid (1 g), Immunobak (1 g), Provagen
(10 g ) Vetom 1.1 (50 mg / kg body weight), Bacell
(0.3% by weight of the feed) and Monosporin (10
mL), contributes to the improvement of their
reproductive qualities: for twins - on 2,2-12,2% by
krupnoplodnosti - by 8,0-10,7%, for milk - by 8,9-
36,5%, at the preservation of pigs - by 1,3-8,3%, by
weight of the nest 2 months of age - 22 , 9-38,9%
compared with the control. At weaning piglets from
sows experimental groups indicators of natural
resistance were significantly higher. The best
reproductive performance were observed in sows
treated with diet and probiotic supplements
Immunobak Bacell combined with Monosporin . The
results of these experiments revealed adaptogenic
properties of the studied additives, their ability to
mitigate the impacts of technological stresses,
reducing as a result of the cost of the products. Of
great practical importance is the ability to predict the
effectiveness of the use of additives which have antistress
effect, depending on the body weight of
animals, their age, frequency and duration of their
application before and after the impact of
technological stressors in the suckling period, the
periods of rearing and fattening up of live weight and
100 и 120 kg
We have performed an analysis of the current state of
rice seed production in the Krasnodar region. It is
shown that over the last 10 years in Kuban a full
variety changing took place, which was caused by
State support of rice seed production on the federal
and the regional levels. Agricultural producers of the
Krasnodar region have completely stopped cultivation
of medium-ripening rice of Liman variety, increasing
acreage of new varieties such as Victoriya, Sonet,
Diamant, etc. which allowed to increase crop yield
from 47,1 centner/ha in 2006 to 63,0 centners/ha in
2015 and to improve the quality of commercial grain,
decreasing the content of red-grain forms average in
the Krasnodar region from 20,5% in 2006 to 1,8% in
2015. Legal basis of realization of state agrarian
policy in the field of seed production of agricultural
crops, including rice is reviewed, recent changes in
the legislation of the Krasnodar region concerning
seed production of agricultural crops are shown, as it
was reflected in the Law of the Krasnodar region №
3062-KZ dated 28.11.2014 "On the regulation of
certain relations in the field of seed production in the
Krasnodar region". Areas contributing to the
development of the rice seed production in the Kuban
region are identified for further conducting of variety
changing, introducing new high-yielding varieties into
production as well as varieties of special purpose for
import substitution
The article presents a study of acclimatization characteristics and the effectiveness in the use of Holstein black-and-white cattle imported from Germany, Denmark and the USA under the conditions of the Central Non-Black Soil Area of Russia. The analysis shows that the imported animals are exposed to a number of stress factors that often cause the diseases and serious losses of cattle. The main reasons for the losses of heifers were the pathologies of the reproductive organs and the mammary gland (26,3%), locomotor system and distal extremities (15%), respiratory organs (21,2%), etc. The highest-producing dairy cows were those imported from the USA (9158 kg of milk throughout the first lactation). For the yield of milk, they are superior to animals imported from Germany in 1828 kg (P≥0,999) and those imported from Denmark in 1184 kg (P≥0,999). The average American Holsteins’ milk over a 305-day lactation is higher in fat (4,14%) than that of their German (in 0,28%) and Danish (in 0,21%) counterparts (P≥0,999). The same tendency is observed in the protein content in the milk
To study the effect of pumpkin flour on the
physical and chemical parameters of semi-finished
and finished products, 10, 15, 20 % of the weight
of wheat flour in the dough was incorporated to the
dough mass. As a result of the research and the
analysis of wafers with different PF dosages, the
dosage of 15 % pumpkin seed flour from the wheat
flour mass in the dough was accepted as the
optimum one. After selecting the optimum dosage,
the experiment on identifying the dependence of
dough viscosity on the shear rate was carried out.
The samples were taken without adding PF into
dough and with adding PF for 15% from the
weight of the flour in the dough. The results
showed that the viscosity of the control dough
sample was higher than that with 15% of flour
from pumpkin seeds. This is due to the general
decrease of the amount of swellable proteins in the
dough due to the incorporation of PF. Thus, we can
conclude that the introduction of the investigated
additive into the wafer dough does not obstruct
dosing the semifinished product into the wafer
moulds. The analysis of the obtained data as a
result of the research work has shown that
incorporating pumpkin seeds flour into the recipe
of wafers is expedient both in terms of enriching
the product with proteins, fats and biologically
active substances and in terms of improving the
process in the production
Nicotiana tabacum and rustica are facultative self-pollinated plants, therefore, because of pollination peculiarities, specific methods are applicable to growing seeds of this plants. Researches on mass, individual and family, recurrent methods of seeds selection for productivity and sowing properties are carried in the institute for revealing most efficient methods of getting seeds. Seeds growing system for Nicotiana tabacum and rustica is a part of general seeds growing system for all agricultural plants and consists of breeding, testing new sorts, mass reproduction of seeds with retained biological and productivity properties, seeds harvesting and controlling their sort and sowing properties. Primary growing of nicotiana tabacum and rustica seeds is carried by individual and family or recurrent selection and further testing of chosen plants, distinctive for this sort, on economically valuable and biological properties. Peculiarities of each zoned sort are kept by retaining its primary genome with constant selection of highly productive genotypes, specific for this sort. Well-organized seed growing system leads to sort potential revealing. Biotype composition of sort is obviously changing in a few years, so primary seeds growing system should be constantly improved
Peach fruit is much demanded worldwide. The
success of its cultivation depends on the optimal
plant placement of all the huge biodiversity
considering the cultivar demands. The northern
boundary of the peach cultivation passes through the
Kiev-Kharkov-Rostov-on-Don, Maikop, Nalchik,
Grozny, Astrakhan (Witkowski, 2003). However,
because of extreme temperatures there are almost no
suitable areas for Peach crop cultivation in these
borderlands, in the Krasnodar and the Stavropol
regions. From the other hand, extreme temperatures
for peach cultivation in the humid Russian subtropics
were not observed. Spring frosts till -5 ° C were
observed in 2004, 2014. However, the cultivar
productivity in the region influenced by the duration
of low temperatures (7,2 ° C and below) that were
observed from December to March. The amount of
low temperatures for each cultivar was established
using the highest coefficient of yield determination,
depending on the temperature, amount of
precipitation and the "cooling unit." The yield of
peach cultivars is closely linked with the abovementioned
agro-climatic conditions during the
flowering period. Paired correlation coefficients of
yield with precipitation and with temperatures (for
most cultivars) were negative, and since they are
unregulated value, the flowering phase is crucial for
peach culture in the Russian subtropics
The article describes the efficiency of a feed additive
called "Tetra+" during chronic mycotoxicoses of pigs.
The purpose of carrying out series of experiments on
sows was to determine the therapeutic and
prophylactic effectiveness of innovative feed additive
"Tetra+" during combined chronic mycotoxicosis in
pigs and to study the influence of feed additive on the
growth, weight, preservation and overall resistance of
sows. The results of the experiments revealed that a
feed additive "Tetra+" has had a positive impact on
large-fruited of pigs; it can also be concluded that the
feed additive "Tetra+" has a positive effect on the
metabolism of proteins, carbohydrates and has
antitoxic properties
Ragweed plant became quarantine malware on the
territory of Southern Russia. In the Krasnodar region it
has been extended to the territory of more than 4.62
million hectares. In the areas of its growth, it causes
great damage to agriculture. By developing a strong
root system and aboveground, it inhibits the row crops,
especially sunflower. Another problem with this weed
is producing large amounts of pollen that causes
allergic reactions in the majority of residents of the
province. This article discusses the importance of
using modern methods of ragweed oppression,
including chemical and biological methods in
sunflower crops
