Intergeneric hybridization was carried out between various accessions of Hordeum jubatum (4x) and cultivars of Triticum aestivum (6x) and Triticale (6x) as well as T.monococcum (2x) and between cultivars of Triticum aestivum (6x) and the hybrid (Horodeum jubatum 4x X Secale cereale 4x) in both directions.The hybrid progeny was obtained via embryo culture from crosses of H.jubatum x T.aestivum and T.aestivum x(H.jubtum 4x X S.cereale 4x).The hybrid of H.jubatum x T.aestivum was produced at the frequency of 1.7% in relation to pollinated florets and five hybrids of T.aestivum x (H.jubatum 4x x S.cereale 4x) from successful combinations were produced at the frequency of 2.00-4.88%.The hybrids exibited varitionin somatic chromosome number.In meiocytes of two T.aestivum x (H.jubatum 4x X S.cereale 4x) plants a high chromosome instability was also found.The chromosomes were associated mostly as univalents, but some pairings (0.03-3.50 per cell) mainly as rod bivalents were observed.
