Variety traits
Hordeum vulgare L.
Heterosis in barley manifests as the superiority of first-generation hybrids over parental forms in terms of productivity and adaptability traits. Its practical application is limited by the biology of this self-pollinating crop, so research is primarily breeding-genetic in nature.
In the reference 4 varieties crop Barley, where this is mentioned in the description.
To evaluate heterosis in barley, researchers compare F1 hybrids with the better parent, the mid-parent value, or a standard cultivar. The effect is quantitatively expressed as a percentage. In breeding studies, both positive results, reaching up to 12–13% in grain weight per plant, and negative values, down to -32% depression, are recorded, depending on the specific cross combination.
The heterotic effect in barley is evaluated based on key productivity traits, such as grain weight per plant, number of grains per spike, and productive tillering. The inheritance of 1000-grain weight and plant height varies from depression to overdominance. Due to the crop's flowering characteristics, large-scale production of hybrid seeds is difficult; therefore, breeding work is focused on studying inheritance mechanisms and developing promising germplasm.
