On the basis of studying of collection of sorghum, the samples with important signs and properties for use in selection are marked out. Sterility fixers are defined as a result of studying of the samples on CMS, and sterile lines with the high combined ability are created
In the article we have studied biological and morphological features of perspective varieties of apple-trees of different ecological and geographical origins. Taking into account the requirements of intensive gardening we have defined biometrics, water regime, allowed to estimate the variety and determine its ecological plasticity.
We have allocated apple-tree varieties of native selection such as Krasna Darya, Kuban scarlet, Peach, Renet Kuban and Pamyat Easulu; introduced varieties: Enterprise, Fuji, Red Chief, Golden Bee for sortment renewal and creation of intensive plantations of apple-trees in the Chechen Republic
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.
Differentiation has been conducted and valuation of the collection of lavender angustifolia and Lavandin according to the content of linalyl acetate, biometrics is shown, and correlations of economically valuable indicators in the cluster analysis are identified
The article gives the results of the study of the texture
of the grapes and biochemical characteristics of red
wine grape varieties of Cabernet Sauvignon, Cabernet
Franc, Merlot, Sapeari, Tsimladar, Pinot Noir for the
production of juice of direct extraction and blending.
The studied varieties in terms of the structure of the
cluster may be divided into three groups of blackpinene
(21.1), Cabernet Franc and Tsimladar (18.7 -
17.5), Cabernet Sauvignon, Merlot, Saperavi (16.5 -
16.8) , and bunches of addition in terms of two groups
- Tsimladar (17.6), Cabernet - Sauvignon and other
(15.6 - 16.4). The structural component of grapes varieties
ranged from 5.2 to 5.9, berry index - from 62.1 to
83.4, the output of the wort from 74.2 to 76.3%. The
content of sugars and acids in the berries of all varieties
is favorable for the production of beverages. The
largest Tartaric acid content was found in the juice of
the varieties of Cabernet Sauvignon, Pinot Black,
malic acid - in the juice of varieties Saperavi, Merlot,
Tsimladar, citric acid - in the juice Tsimladar varieties,
Cabernet Sauvignon, Saperavi. The ratio of tartaric
acid to the content of the apple juice Cabernet Sauvignon
was 2.9: 1, Cabernet Franc 2.6: 1, Pinot Black
2.5: 1, Merlot and Tsimladar 1.6: 1, 1.1 Sapevari: 1.
According to the content of potassium cations, sodium,
magnesium and calcium there were chosen three varieties
of Cabernet Sauvignon and Cabernet Franc. The
lowest content of potassium and magnesium cations
was in the variety of Tsimladar, Sodium – in the varieties
Merlot and Saperavi, calcium – in Saperavi. Excellent
tasting commended for juices was given to
Cabernet Sauvignon, Saperavi, Tsimladar, good – to
Cabernet Franc, Merlot, Pinot black. Best blending
juice obtained by mixing the juice of the grape of the
varieties of Cabernet Sauvignon and Pinot black
70:30, Saperavi and Pinot black 50:50. From the
grapes of produced varieties, we can produce juice and varietal by name ampelographic variety and blended to
extend the range
Diseases cause great damage to agriculture, reducing
yields and decreasing its quality. The losses
are up to 20-30% of potential crop yields. Different
types of rust and powdery mildew cause significant
damage to wheat. Thereby, the growing of
varieties tolerant to these diseases is of great importance
at present. It allows solving such problems
as the improvement of stability of grain production
(especially in the epiphytotic time), improvement
of its quality and reduction of prime
cost of the product. Cultivation of resistant varieties
gives the opportunity to avoid a use of crop
protection chemicals and thus, to improve environment.
The researches were carried out in the
laboratory of intensive soft winter wheat breeding
and seed-growing of FSBSI ARRIGC after I.G.
Kalinenko in 2013-2015. The crop was sown in a
bare fallow. 275 samples of soft winter wheat from
the world collection VIR, Turkey (CIMMYT),
new varieties of domestic and foreign breeding,
varieties and constant selection lines of own selection
were the subjects of the study.
Favorable for disease development weather conditions
allowed evaluating collection samples according
to the degree of infection with leaf rust and powdery mildew under natural conditions.
According to a complex resistance to leaf rust and
powdery mildew we have distinguished the following
samples: ‘Nakhodka’, ‘1226/98’, ‘662/99’,
‘1366/08’, ‘Patriarkh’ (Russia); ‘Shestopalivka’(Ukraine);
‘Simonida’ (Serbia); ‘MV 15-04’
(Hungary); ‘Rialto’ (England); ‘Menestrel’
(France); ‘№42 CIMMYT’ (US). Thus, our conducted
study resulted in distinguishing the samples
of soft winter wheat which are resistant to leaf rust
and powdery mildew and are recommended to use
as a source of resistance and tolerance to these
pathogens. The samples with a combined resistance
to both pathogens are of particular interest
Dispersed colloidal particles pertaining to positive colloids is played important role in the process of the interaction of organic wastes (sewage sludge, defeca-tion mud, chicken manure, etc.) with various wastes of mineral raw materials (phosphogypsum, lime powder, halite, etc.)
Studied the investigation of the therapeutic effect of experimental mixture of four non-transducing E. coli bacteriophages and it combinations with probiotic, designed on the basis of the endemic Lactobacillus paracasei strain, previously isolated from pigs in this age of the local population in the state, the survival rate and laboratory parameters of pigs with post-weaning diarrhea. The most influence on the correction of E. coli dynamics has a combined oral administration of phage medicine and probiotic preparation established. The most influence on the dynamics of titer phages has not only the combined using (both oral and intradermal) of phage medicine with the probiotic preparation, but also an isolated ingestion of phage mixture
The value of the initial material for selection for heterosis
is primarily defined by the combining ability in
respect to the main economically valuable characteristics.
Combining ability with respect to “grain productivity”
has been studied among fourteen selfpollinated
lines of maize of early ripening and three
testers in the system of hybrid combinations. We have
proved that weather conditions have an influence on
the variability of the estimates of the combining ability.
We have identified the new self-pollinated lines of
maize SP 165 and SP 175, which are characterized by
invariably high evaluations in the effects of GCA (gi)
in different years. The new self-pollinated line SP 167
has got high variants of SCA (δ2si). The new lines SP
161, SP 163, SP 167 and SP 174 have been characterized
by the variability of the evaluations in the effects
of GCA. They are related to the first or second rank in
respect of GCA, depending on the year of the conducted
evaluation. These are SP 163, SP 164, SP 170,
SP 171 and SP 173 that have differed by their variability
of the variants of SCA (from the low variants to
the high ones). The highly productive testcross hybrids:
Madonna M × SP 165 (4.88 t / ha), Madonna M
× SP 171 (4.85 t / ha), Madonna M × SP 167 (4.80 t /
ha), T 7M × SP 165 (4.78 t / ha) have been obtained
based on the self-pollinated lines having invariably
high figures of GCA and SCA
The article proposes a system of regression equations to
estimate the parameters of the normal probability distribution of the number of trunk diameters in stands of oak plantations of Lower Volga. Commodity tables for estimation of forest stands are developed
