Summary: The research results of evaluating soybean varieties by adaptability (ecological plasticity and stability) in different soil-climatic conditions have been presented considering the resistance to disease (fusarium, bacteriosis). The soybean varieties have been ranked by ecological plasticity and stability in accordance with their reaction to environmental factors. In terms of resistance to fusarium during the research period, in different ecogradients of varieties Hoverla – 86,6%, Oriana – 83,7% and Vezha – 81,2% have revealed themselves. Higher rates of resistance to fusarium have been provided by varieties with different reactions to changes in environmental conditions. The Hoverla variety belongs to the first rank, the coefficient of ecological plasticity (bi) – 0,38, that is, < 1, and the variance of stability (S²) ˃ 0. Vezha and Oriana varieties belong to the sixth rank in terms of the reaction of growing them in different ecogradients, the coefficient of ecological plasticity (bi) is 1,12 and 1,3, and the variance of stability (S²) ˃ 0. In terms of resistance to bacteriosis, soybean varieties of Hoverla – 84,1%, Oriana – 81,7%, Vezha – 79,7 and Femida – 78,6% have been noted. Varieties Oriana, Vezha and Femida belong to the highly plastic in reaction to changes in growing conditions, (bi) ˃ 1, and variety Hoverla is conservative in reaction to changes in hydrothermal and soil growing conditions (bi) < 1. Variety Hoverla has been distinguished by a slight reaction to changes in environmental conditions, providing a high stable indicator of resistance to both fusarium and bacteriosis, and varieties Oriana and Vezha to highly plastic, which respond well to improved growing conditions. However, considering the highest quantitative values of disease resistance of these varieties in different ecogradients, they belong to the adaptive ones.
