HYBRIDOLOGICAL ANALYSIS OF PLANT RESISTANCE OF WINTER WHEAT TO P. triticina
06.00.00 Agricultural sciences
Description
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)

Description
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. Thus, at the shifting of maize sowing dates with the second half of may on the second half of April, the optimization of heat regime in the generative period and rising of efficiency of use of thermal of resources of the region. There was marked the acceleration of development of corn seedlings when the average daily air temperatures was up to +12 ° C at the samples with the application of the disinfectant TMTD-plus

GLAUCONITE AS A POTENTSIAL NEW LOCAL FERTILIZER AT KUBAN REGION
06.00.00 Agricultural sciences
Description
The analysis of use of glauconitic sand is provided in the article as a potential local fertilizer in the conditions of Kuban. The research of its agrochemical properties showed high value of this substance as fertilizers. In its structure we found macro - and microcells which are necessary for mineral nutrition of plants. Fractionation of phosphorus and potassium in various acids showed their different availability for the plants, which will help to consider glauconite as a fertilizer of prolonged action
