Abstract: The article presents the results of analysis of the degree of phenotypic dominance of spring barley hybrids of the first generation. Experience was founded on the basis of the research laboratory breeding of crops VPO Far Eastern State Agrarian University (Blagoveshchensk) in 2013-2014. F 1 hybrids were sown by hand in rows 0.9 m long; as standard were parental forms. Harvesting is done by hand (with the root system). Biometric analysis was performed in the laboratory. Most of us studied hybrids heterosis appears simultaneously on two grounds 2; two hybrid combinations at this stage can be attributed to not very promising from the economic point of view, as they have the inheritance of agronomic traits of F 1 hybrids passed by the type of depression (which Alexis х Talovskiy 9 and Simon x South). Only one hybrid surpassed their parental forms at the same time on a 5-featured Alexis х Simon, what it says about the value and necessity of careful further study.
