The assessment of the inheritance and heritability of quantitative traits in 36 hybrid populations of barley (Hordeum vulgare L.) under greenhouse conditions was the presented study’s focus. Results revealed the predominance of additive gene action for controlling the studied traits, indicating the possible effective selection in the F2 generation. For selection in early generation, the most accessible traits were plant height, ear length, and grains per ear, with their variability due to an additive gene action, which is more helpful to conduct targeted breeding work. Barley hybrid populations’ detection with the highest heritability coefficients for specific traits have shown in Rihane x Saule (for five traits) and three hybrids Syr Aruy x Donetskiy 8, Syr Aruy x Odesskiy 100, and Harmal x Saule (for four traits). This suggests selecting the highly productive hybrids adapted to stressful environmental conditions.

By studying barley (H. vulgare L.) hybrid populations under artificial climate conditions, the genetic criteria and intensive selection can be helpful for a comprehensive assessment of breeding material based on economic traits.
