The environmental test and evaluation of grain sorghum varieties in terms of productivity, plasticity and stability were carried out in the conditions of the central part of the Lugansk region on the basis of the experimental field of the Lugansk State Agrarian University in 2016-2020. The analysis of two – factor experience (factor A – years, factor B – hybrids), coefficients of ecological plasticity and stability, general adaptive ability of genotype, coefficient of yield variation, intensity index, stability index, indicator of level of variety stability were used for the assessment. The climate change index made the greatest impact on the yield. As a result of the study of 20 hybrids of foreign selection included in the State Register, varieties with the highest yield, adaptability to growing conditions, plasticity and stability were bred for the arid conditions of the Lugansk region - the early-maturing hybrid Frisket (ADVANTA company), medium-early hybrids Puma Star (ADVANTA company) and Solarius (EURALIS semences company).
