The study was conducted at the V.M. Remeslo Myronivka Institute of Wheat of NAAS in 2018–2020. The 96 spring barley accessions originating from 15 countries were evaluated in yield performance and its stability. The mean yield in the trial through the years varied from 265 g/m2 in 2018 to 447 g/m2 in 2020. The difference between the minimum and maximum yield of samples within individual years was 388 g/m2 in 2018, 522 g/m2 in 2019, 440 g/m2 in 2020. Thus, it was found that the studied genotypes differed significantly in the level of yield, both within a year and through years of the research. This is confirmed by the high percentage of the genotype in the total variance — 36.73%. The 15 accessions which in mean yield for three years exceeded the standard Vzirets have been identified. The genotypes Almonte (CAN), Smaragd (UKR), Skald (POL), and Vienna (AUT) had the optimal level of yield in contrasting weather conditions of different years. These accessions are the most valuable genetic sources for breeding usage under conditions of the central part of Ukrainian Forest-Steppe. The accessions Suveren (POL), Krok (UKR), Kormoran (POL), Severyanin (RUS), Avers (UKR), Tiver (UKR), Dar Nosivshchyny (UKR), Skarb (POL), AC Alma (CAN), Despina DEU), Glacier AL.38 (GBR) were characterized by different responses to contrasting weather conditions of different years. Therefore, when involving them in hybridization as parental components, a combined approach will be appropriate which based both on the ecological-geographical principle as well as taking into account the yield performance, depending on the conditions of different years. In order to comprehensively assess the genotype by environment interaction and to select genotypes with the optimal combination of yield and stability, it is advisable to combine statistical (graphical) models that differ in the principles of evaluation of genotypes
