The valuable genes of Aegilops biuncialis, Ae. ovala, Ae. kotschyi, and Ae. variabilis were transferred to rye, by crossing Aegilops-rye amphiploids with tetraploid and diploid substitution rye. The C-banded karyotype of the BC₁ and BC₂ generations of amphiploids with 4x substitution rye and BC₁ with 2x substitution rye showed great variation in chromosome number and composition. In the BC₁ generation of amphiploids with 4x and 2x substitution rye, seed set success rate and germination rate varied depending on origin. However, plant sterility in all cross combinations of amphiploids with 4x and 2x substitution rye resulted in their elimination from further experiments in the BC₃ and BC₂ generations, respectively. In backcrosses of 4x substitution rye with amphiploids Ae. variabilis x rye 4x, fertile 4x rye plants containing Aegilops chromatin were produced in the BC₂ generation.
