In agricultural production, it is important not only to achieve a high productivity, but also to ensure its stability. To obtain high and stable yields, it is necessary to have information on the adaptability of crops varieties and hybrids to a specific cultivation zone. The article analyzes the results of the field experiment on the variety testing of sweet pepper. To assess the variety for adaptability to natural conditions and cultivation technology in the Astrakhan region, such parameters as plasticity and stability of the variety were used. To characterize the ecological plasticity, the regression coefficient bi was determined, which characterizes response of the cultivar to changes in cultivation conditions. To characterize the parameter of stability, the standard deviation from the regression line 2d. was calculated. All calculations were carried out according to S.A. Eberhart, W.A. Russell as presented by V.Z. Pakudin.
