abstract 1201606094 issue 120 pp. 1403 – 1413 30.06.2016 ru 276
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)

HYDRAULIC RESEARCHES OF DIMENSIONLESS EXPENSE DESCRIPTIONS OF REGULATIVE ORGAN OF MODEL STANDARD OF BAND REGULATOR OF WATER

abstract 1131509071 issue 113 pp. 964 – 984 30.11.2015 ru 995
The purpose of the researches was the necessity of deep study of hydraulic dimensionless expense descriptions of regulative organ of model standard of band regulator of water, for rice checks. Rice is one of the most moisture-loving agricultural cultures. Its productivity straightly depends on adjusting of water level in rice cotter pins on the different periods of development of this culture: period of primary submergence of check, fight against weeds, primary vegetation, phases of bushing out, vegetations of suckling and cereous ripeness. On each of the considered periods of development of plant the guided water level is needed, that high-quality can be realized only at application of the systems of automatic control. In rice irrigation systems there is plenty enough of losses of water due to not managed leakage in regulator flow and water level in the closed position. An actual and meaningful task is development, research and introduction in practice of reliable and high-efficiency regulators expense and water level for rice checks. The article presents results of research of hydraulic dimensionless expense descriptions of regulative organ of model standard, developed by us. Intercommunication of degree of influence is investigational, on the basis of application of methods of planning of experiment, on the function of response, which dimensionless expense description of regulative organ of model standard of band regulator of water, relations of diameters of the downlow openings, is taken for, at the different relation of workers pressures. From appraised experimental data approximation dependences, which were in same queue analysed for the purpose cross-correlation connection, determination, elasticity, are built. Also, in the article there is an estimation of statistical meaningfulness of the built model of regression given with the use of criterion of F - Fishera and parameters of equalization of regression with the use of criterion of t - St'yudenta, at the set level of meaningfulness α. At the permanent relations of workers pressures the analysis of sections of surface of response H/Нmax 0,6; 0,8; 1,0 shows that functions have extremums on a maximum. At minimum relations of workers pressures H/Нmax equal 0,6 the maximal value of function of response is equal 81% it will be at the relation of diameters of the downlow openings of d/dmax equal 0,9. With the increase of relation of workers pressures H/Нmax to 0,8 have a trend of maximum toward an increase and here he comes at the value of function of response equal 94% and relation of diameters of the downlow openings of d/dmax equal 0,92. Further increase of relation of workers pressures of H/Нmax to 1,0 also results in the trend of a maximum of function of response which arrives at a value 118%, here the relation of diameters of the downlow openings of d/dmax is equal to 0,94. The combined analysis of curves shows that at any relation of workers pressures, the degree of influence on the function of response increases due to more relation of diameters of the downlow openings

There were reviewed the results of the study of the dependence of main of phenological phases of development of corn hybrids of different maturity groups of selection of Krasnodar Research Institute of Agriculture named. P.P. Lukyanenko in a zone of sufficient moisture of Central Ciscaucasia (Ross 199, Ross 299, Krasnodar 382 and Krasnodar 410) and the All-Russian Research Institute of Corn (Mashuk 170, Newton, RIC 345 and Eric), as well as early-middle middle Rossiyskaya 1 from the change of average daily air temperature at different dates of sowing and preplant seed treatment by the preparation "TMTD-plus" containing the growth promoter called Krezatsin in its composition. The studies were conducted in accordance with the thematic plan of scientific researches of the department of crop and forage production of Stavropol State Agrarian University. The technology of maize growing on the experimental plot corresponds to the standard technology for this area and culture. The sowing was performed in three stages. The first (early) sowing period was at t = + 7 ... +8 ° C. The second (recommended) – was at t = + 10 ... + 12 ° C. The third (later) sowing period was carried out at t = +15 ° C. There was identified a high inverse correlation between the average daily air temperature and the duration of the intraphase periods of maize propagation.

IDENTIFICATION OF MAIZE LINES ACCORDING TO THE CONTENT OF ALLELES OF «C» TYPE FERTILITY – RESTORER GENES

abstract 1141510054 issue 114 pp. 711 – 719 30.12.2015 ru 803
Based on the analysis of the nature of some flowering test crosses which have been resulted in the hybridization with purposely chosen sterile sources (analyzers), the new self - pollinated lines of maize have been identified according to the content of fertility-restorer genes of ‘C’ type of CMS. Genotype of the line RD 257 - rf4rf4rf5rf5Ff6Rf6 (class II), genotype of the line RD 245 - rf4 rf4 Rf5 Rf5 rf6 rf6 (class III), genotype of the line RD 274 - rf4rf4Rf5Rf5Rf6Rf6 (class V), genotype of the line RD 231 - Rf4Rf4rf5rf5Rf6Rf6 (class VI ) genotype of the line RD 261 - Rf4Rf4Rf5Rf5Rf6Rf6 (class VII). The identification of the content of the alleles of fertility - restorer genes allows forecasting the nature of flowering hybrid progeny resulted in the hybridization with a known genotype. We have created a catalog of self - pollinated lines of maize according to the fertilityrestorer genes, which consists of 18 lines, which have been studied in all the years of research. We have identified the lines belonging to classes I, II, III, V, VI, VII and VIII. During the transfer of maize hybrids on a sterile basis the lines of classes I and VIII are those ones which have been of great interest. The self - pollinated lines KV 204, SP 286 (class I) are the reliable fixers of «C» type of CMS. The progeny resulted in the hybridization with any sterile lines is characterized by complete sterility. The new self - pollinated lines KV 498, KV 272, KV 227, SP 357, RD 261 (class VIII) are constant natural fertility-restorers. They are able to fully restore fertility in hybridization with any sterile lines and in any growing conditions

IMPACT OF AN AMENDMENT FOR SOIL STRUCTURE IMPROVING ON SOIL AT SPRINKLING

abstract 1061502020 issue 106 pp. 313 – 323 28.02.2015 ru 891
The article presents the research results of the impact of amendment improving soil structure on soil upon sprinkler irrigation of agricultural lands. It is proposed to use artificial aggregation of soil for water erosion control via composition of structure-forming materials. The developed composition includes slagheap rock, bentonitic clay, claydite screenings, and shell limestone. Adjusted analytical relations of the impact of the amendment on runoff coefficient depending on the intensity of artificial rain upon irrigation of agricultural lands, slope, and water permeability have been revealed. Regression analysis of spectral surfaces has shown that slope of irrigation site has a significant impact on the increasing of runoff coefficient values, while correlation coefficient equals to 0.97. Water permeability has negative correlation, -0.85, with increasing the values of runoff coefficient. The relation between runoff coefficient and intensity of artificial rain is less strong, 0.89. We have determined that applying of the given amendment provides decreasing of runoff coefficient by 15 % depending on the slope of irrigation site, and by 20 % depending on rain intensity. Experts in the field of land reclamation can use obtained analytical relations for predicting surface soil loss when estimating the efficiency of amendment applying to control soil erosion activities at agricultural lands
