Adaptability of moderm soybean varieties to environmental stresses

Abstract

We present the results of research into drought and cold tolerance of 34 modern soybean varieties developed in the leading breeding institutions of Ukraine. The objectives on evaluation of tolerance to abiotic factors by ability of seeds to germinate at low above-zero temperatures and insufficient moisture were achieved. Varieties with consistently (throughout the years) high cold tolerance and average drought tolerance in combination with increased (in comparison with the check varoeties) yields were identified and classified as valuable sources on grounds of their adaptability to stressful environmental conditions.
