ABSTRACT
The distribution of fruit crops in the regions of a country according to their requirements to the weather and soil growing conditions makes it possible to achieve the optimum productivity and fruit quality by means of realizing the agrobiotical factors and crop characteristics valuable for economy, that is to use to the fullest degree their biological potential which means the total spectrum of the characteristics variability that manifest themselves as a result of the genotype and environment interaction. It is just the factors, which ensure the optimum productivity and fruit quality that are of the greatest importance in this variability [1-4].
