The urgency of soybean breeding for increasing resistance to low temperatures is caused by a large share of the arid regions of Moldova, where the increase in productivity can be ensured by carrier earlier plant-ing and ripening periods before the summer droughts peaks. Thus, as a result of the studies carried out, it was found that when germinating seeds at a temperature of 4˚C, selection is stricter and more efficient. Sowing in the early stages is possible, since soybean seeds remain viable at low temperatures, and when the temperature rises, the best varieties reach the germination rate characteristic of optimal conditions.
