COLLECTION SAMPLES OF SOFT WINTER WHEAT TOLERANT TO LEAF RUST AND POWDERY MILDEW
06.00.00 Agricultural sciences
Description
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

PRUNING OF FRUIT-BEARING ORCHARDS OF APPLE ON MIDDE TALL ROOTSTOCKS
06.00.00 Agricultural sciences
Description
In the North Caucasus there is about 50% of fruit plantations of the old type: stocks with strong and low power of growth, planting density from 320 to 416 trees/ha. The trees reach 6 feet high, the crown is thickened, minor crops and poor quality. One of the main causes of low profitability of such plantations is low intensity of pruning

Combining ability with respect to “grain productivity” has been studied among thirty eight self-pollinated lines of maize of mid-early and early maturing in the system of hybrid combinations. The lines with high general (GCA) and specific (SCA) combinative ability have been hybridized. New high heterotic hybrids have been developed on the basis of lines with high GCA and SCA

LANDSCAPING THE CITY OF MAKHACHKALA WITH VARIOUS PLANTS
06.00.00 Agricultural sciences
Description
The total area of green spaces in the capital of Dagestan now stands at 3003.5 hectare, and in the mid-1960s - 186 hectares. Green areas of common use per capita in 2015 compared to 1960 has decreased dramatically and amounted to 3.6%, which is only 1.0% of the norm. The race of landscape construction of the city far behind the race of construction of residential and office sectors, and the existing green spaces either in quantity or quality does not matches the sanitary and aesthetic requirements, in addition there is a low level of artistic and architectural planning of green space. We have also described the questions of the history of the garden and the park building in Makhachkala and meticulously analyzed the rock-species (species, forms, varieties) of the composition of green space. We have marked the evaluation of their condition. Despite the great diversity of species composition (281 kind of woody plants, including 60 species of gymnosperms and angiosperms 221 views), we have noticed that almost everywhere there was cultivated only a small part of them. This is despite the fact, that the Republic of Dagestan has a rich species diversity of local flora, which can be effectively used in landscaping. Here, too, there are favorable climatic conditions for the introduction of new species. It should be noted that the private sector can be traced as having the opposite trend. Some recommendations have been given to improve the structure and condition of the trees and bushes planted in the city. Finally, we have shown the necessity of linking the production of green building works with the scientific activities of specialized education and research institutions in the city

Description
The influence of growth, its ripened part and the diameter of the vine at the base of the shoot on the growth power of 922 seedlings of 55 combinations of crosses in 2011 and 2012 was studied (planting scheme 3 x 1 m), seedlings of grapes of the second and third years of vegetation in the field conditions of the Southern coast of Crimea. The mean vine maturation for all populations was 64.7%, the diameter at the base of the shoots was 3.3 mm. After pruning to reverse growth, in the third year of vegetation of seedlings (2014), the length of growth of shoots increased significantly and the average for populations it became 73.3 cm. The coefficient of variation increased, 26%, - it acquired the character of a significant deviation from the general population. This happened because the seedlings, which had a vine growth less than 25 cm in the second year of vegetation, had a growth of only 35 cm in the third year, whereas in all seedlings that had a growth of more than 30 cm, in the following year shoots increased almost 1, 5 and 2 times more. Formulas are proposed for estimating the growth force of seedlings according to the 9-score scale OIV (OIV)
