    Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
    Isogenous lines were obtained by doubling the chromosomal set of androgenetic haploids achieved byïn vitro"anther culture derived from inter- and intraspecific Nicotiana hybrids that were in the F1-F4 generation. Dihaploid genomes that include ...

    Investigations relative to the preservation of the genetical information in an isogenetic line obtained from a tobacco androgenetic haploid and its cytogenetics

    PATRASCU M.
    Central Research Station for Tobacco Culture and Industrialization, Bucharest, Romania.
    Cytogenetic investigations were carried out on a tobacco isogenetic line (Molotava 72 x Nicotiana glauca F5) x Ghimpati RP 55 F3, obtained from an androgenetic haploid and compared with the hybrid from which were derived the haploid and the parents of the ...
