The high level of polymorphism has been revealed in cv. Zvezda by C-banding and the wheat storage protein electrophoresis. Moreover, the cv. Zvezda derivatives have been found to be monomorphic. Genomic in situ hybridization and C-banding failed to reveal introgressions of E. intermedia into cv. Zvezda genome. The peculiarities found for Zvezda odnostebelanava(single-stem) and Zvezda nizkostebelnaya (short-stem) lines are of special value for the further application in breeding programs.
