The reaction of two pear varieties (Kieffer with reduced winter hardiness and Leven with increased winter hardiness) on the changing climatic conditions of winter-spring period from 1986 to 2018 on the territory of Krasnodar region was studied. The critical minimum temperature is detrimental to flower buds of the studied varieties in different phases of the winter-spring period. Thermal stress manifestation in time and space is calculated. Digital maps of dynamic changes in the periodicity of the temperature conditions in the winter-spring period for the analyzed pear varieties are compiled. A digital computer analysis of the evaluation of frost hazard territories of Krasnodar region for pears in changing climate conditions was carried out. The proposed scientific approach suggests the need for a transition from registering the impact on the productivity of fruit crops and their varieties of individual environmental factors to evaluate their relationship and interdependence over specific phases of development. It will allow more efficient use the natural potentials of crops, varieties and growing environments without additional capital investments.
