Drought tolerance of barley is a key trait that ensures crop stability under moisture deficit conditions through efficient root system development and the maintenance of productivity during critical growth phases.

where this is mentioned in the description.
To evaluate drought tolerance in barley, laboratory modeling of osmotic stress during seed germination and seedling dehydration methods at the two-true-leaf stage are employed. In field conditions, tolerance is determined on stress-inducing backgrounds using selection indices and morphophysiological indicators, such as biomass, root system development, and the harvest index.
The critical period for barley is the interval from stem elongation to heading, when the crop's moisture demand is at its maximum. Resistant genotypes utilize water more efficiently during these stages, minimize the formation of sterile tillers, and ensure a stable grain yield even under severe moisture deficit.
