PRODUCTION AND CHARACTERIZATION OF BARLEY WHEAT ALLOPLASMIC AND ADDITIONAL LINES

BC3 - BC5 plants of H.vulgare L. (2n=14) x T.aestivum L. (2n=42) hybry ds and BC1 - BC4 plants of H.geniculatum All. (=H.marinum subsp. gusso neanum) (2n=28) x T.aestivum (2n=42) hybrids were studied. It was reve aled that cytoplasmic and nuclear genomes of H.vulgare and H.geniculat um exerted different influence on cytogenetic characteristics of BC pl ants. Cytoplasmic and nuclear genomes of H.geniculatum had more positi ve effect on self-fertility and viability of additional and alloplasmi c lines of T.aestivum in comparison with genomes of H.vulgare. It is n ecessary to study new obtained hybrid genotypes using biochemical test s to indentify substitutional lines.
