The article describes the characteristics of a new variety of spring barley of the selection of the Federal State Budgetary Institution “Voronezh FARC named after V.V. Dokuchaev” Ikorets and presents the results of its study in the nursery of ecological variety testing. The studies were conducted in 2015-2022 in comparison with the most common zoned varieties in the region. The standard was the widespread variety of Priazovsky 9. Analysis of the determination of the adaptability coefficient showed that the new variety provides stable seed yields and adapted to arid and unstable in moisture supply to the conditions of the region (B I = 0.89, Si = 7.18). On average, over 6 years, the productivity of the variety was 3.59 t/ha. The maximum yield was obtained in the State variety testing in 2018 in the Kursk region - 7.59 t / ha, in the environmental test in 2022 in the Rostov region – 6.44 t/ ha. According to the technological qualities of seeds, the variety Ikorets belongs to the brewer group. The value of the Ikorets variety is the optimal combination of productivity, brewing qualities of grain, resistance to lodging and drought.
