The observed increase in global average air temperature has a profound effect on the climate, and the effects of this phenomenon are expected to be more significant in the next 30–50 years. As a result, their physiological condition deteriorates, and their defenses and productivity decrease. This fact emphasizes the relevance and feasibility of the study, which is aimed at determining the drought and heat tolerance of plants of the Moraceae family. The work uses generally accepted methods for determining the resistance of breeding samples to heat and drought. The research established that mulberry plants of Victoria, Halyna, Merefyanska, Slobozhanska, Maclura varieties showed increased adaptive resistance to high temperatures (heat and drought). In particular, damage to leaf plates in the 40-80 °C temperature range did not exceed 50%. Scoring scales were developed for evaluating plants of the Moraceae family for drought and heat resistance, which increased the accuracy and informativeness of their determination. It is emphasized that the general level of physiological processes in germinated seeds under conditions of drought indicates the high resistance of adult plants, which ensures the possibility of preserving and growing valuable species for further breeding. From a practical point of view, the complex diagnostic assessment of Moraceae plants for adaptive resistance by various methods provided a comprehensive assessment and selection of breeding material with high adaptive potential to stressful growing conditions.
