The productivity of a variety is determined by its biological characteristics, growing conditions and the level of plant resistance to biotic and abiotic environmental factors. This article presents the results of studies of environmental testing in 2019-2023 of spring barley varieties for statistical parameters of environmental adaptability. The object of the study is 3 varieties of local selection (Talovsky 9, Osered, Biryuch) and the most widely cultivated varieties of varying degrees of drought resistance in the Voronezh region. The highest yield potential was shown by the varieties of local selection Osered, Biryuch (3.88 and 3.94 t / ha, respectively), exceeding the standard by an average of 11.4-13.3%. The drought-resistant local variety of the old generation Talovsky 9 and the varieties Eifel and Medikum 157 were also characterized by high productivity. The varieties Osered, Biryuch and the multi-row variety Vakula had a high compensatory capacity, while Talovsky 9, Oskolets, Eifel had an average one. Talovsky 9 and Priazovsky 9 had high stress resistance. The most plastic were Eifel, Osered, Biryuch. Talovsky 9, Osered, Biryuch were highly stable (according to PUSS). According to the complex of studied indicators, the varieties of local selection Osered, Biryuch, Talovsky 9 and the Eifel variety were the most adaptive to the conditions of the southeast of the Central Chernozem Region
