Intergeneric hybrids were obtained as a result of crossing barley with alloplasmic rye (with Hordeum jubatum cytoplasm) and the embryo callus culture. The hybrids had a somatic complement of 15 chromosomes: 7 barley and 8 rye (two 1R). The hybrids were vegetatively propagated by clones and tissue culture. Most regenerates from the callus culture had the chromosome number identical to that of the original hybrids and only three plants had 2n=29 and 30. In diploid and amphidiploid plants the SAT chromosomes of rye were suppress1359ed by barley chromosomes. Morphologically both hybrids and amphidiploids resembled rye. Meiotic configurations were observed in the hybrids with 2n=15 and 2
