| dc.description.abstract | Abstract The article gives analysis of practical value of soybean varieties according to productivity and ecological plasticity in different climatic provinces in Ukraine. Ecological estimation of soybean varieties using method of Eberhart S.A. and Rassel W. K. has been made. Variety plasticity and adaptive potential have been defined on the basis of this estimation. It has been established that varieties Almaz and Diona were the best varieties according to the results of ecological variety studies. The most favourable regions for cultivation of up-to-date soybean varieties have been chosen. Variety Almaz has been defined as the most intensive and plastic soybean variety (average yield in years was 2.66 – 2.93 t/hа). Varieties Antratsit and Ametist also have shown high plasticity. Varieties are recommended for cultivation in steppe and forest-steppe in Ukraine. The higher numerical value of coefficient the more variety reaction on improving cultivation conditions. Thus, varieties with higher regression coefficient and lower mean square value have optimal indicators. High sensitivity of some varieties to unfavorable cultivation conditions offen narrows area of these varieties distribution and limits their general distribution. On the basis of examination of soybean varieties in different regions we can predict genetically specific degree of yield stability (adaptation to cultivation conditions). | uk_UA |
