Abstract

Intergeneric crosses of H.geniculatum All (2n=28) with S.cereale L.(2n=28) were made using embryo culture. The tetraploid hybrids obtained were incompletely fertile. After self-pollination or backcrossing with diploid rye, these hybrids set seeds. Cytological examination of a single plant from the self-pollinated seeds revealed 14 chromosomes (7 barley and 7 rye chromosomes). The triploid offspring from backcrosses of the tetraploid hybrids with diploid rye had 21 chromosomes (7 barley and 14 rye chromosomes). Fertile plants were identified among these BC1 21 chromosome plants.
