Materials and Methods. 73 collection samples of spring barley of different ecogeographical origin served as study material.
Primary data were statistically processed by analysis of variance according to
B. A. Dospekhov. Ecological plasticity and its stability variance were assessed using the method and formula by S. A. Eberhart, W. A. Russel, V. Z. Pakudina, L. M. Lopatin.
Results and Conclusions. The results of three-year studies on adaptability of collection samples of spring barley under the conditions of increased soil as exemplified by the following features: plant performance (grain weight), productive tillering, number of grains per ear, 1000-grain weight acidity are presented. By assessing ecological plasticity and variance of its stability the average response of spring barley collection samples to changing environmental conditions was determined. Varieties and hybrids with high plasticity having high regression coefficients and low fluctuations of their stability were selected. We identified samples with stable expression of plant performance (1000 - grain weight) - Adapt; of productive tillering – Іlot and Fenіks; of the number of grains per ear -Oksamytovyy; of 1000-grain weight - Ilek 9.
