Abstract

One important complex analysis methods to analyze the stability and plasticity of investigated varieties, which were carried out by the method Eberhard-Russell. This technique allows to evaluate varieties not only on the average values, but also ductility (b), which reflects the change regression variety of environmental conditions and stability (W) of this reaction. In this method the interaction sum of squares divided each variety of environmental conditions in two parts – Linear regression (b) and nonlinear part, determined standard deviation from the regression line (W). Given the use of regression models evaluation grade reaction to changing environmental factors, regression coefficient (b) serves as an indicator of plasticity variety. Assuming a linear relationship between genotypic and environmental effects regression can use this trait to environmental protection indexes, assessed through the average of all varieties were grown in these conditions. Investigated varieties with coefficient b> 1 belongs to the highly plastic (relative to the group average), while 1> b = 0 grade attributed to a relatively low plastic. If the rate of plasticity grade was not significantly different from unity, then sort the reaction to changing environmental conditions will not differ from the average value of the group. The aim of research was to study the biological characteristics of growth and development medium early soybean varieties, and the formation of their performance. Experimental research on the thesis performed during the 2014-2016 biennium. Research in the field PF "Bogdan & Co.", Which is located in the village. Popelnyky, Snyatynsky district of Ivano-Frankivsk region. In the implementation of the tasks we studied 14 varieties of domestic and foreign selection, which are listed in the State Register of plant varieties suitable for dissemination in Ukraine: Apica, Anzhelika, Kassidi, PODIAKA, Rapsodiia, Aratta, ES Mentor, Luna, Kuban, Atlanta, Sofiia, NS Maksymus, VIDRA, BISER. During the studies used special techniques and general research, technology of cultivation was common for the region. Application methods Eberhard-Russell to determine the stability and plasticity soybean varieties can provide varieties of intensive type, such as Kuban, Vidra, Biser. Comprehensive evaluation method takes into account not only the individual expression of traits in the phenotype, but a reaction to a variety of growing conditions. In this way we can choose to grow in the western steppes of Ukraine soybean varieties high performance main economically valuable attributes that the conditions of use of intensive technologies of forming performance. At the same time the conditions we selected varieties which are in low level of agricultural technology and other negative factors influence yield and stable yield Kassidi EC ES Mentor.
