    Growth and development of the interspecific F<sub>1</sub> hybrids Nicotiana Tabacum L. x N-africana Merxm. Involving different N. tabacum cultivars

    DOROSZEWSKA T.; BERBEC A.
    Institute of Soil Science and Plant Cultivation, Dept. of Special Crops, Pulawy, Poland.
    The species Nicotiana tabacum was mated as male with five cultivars of N. tabacum. The inviability of the interspecific F 1 hybrids was overcome using cotyledon culture. The viable hybrids were compared with their parents for growth rate, plant morphology ...

    Resistance to PVY of interspecific hybrids of several flue-cured tobacco cultivars with Nicotiana africana MERXM

    DOROSZEWSKA T.; BERBEC A.
    Institute of Soil Science and Plant Cultivation, Dept. of Special Crops, Pulawy, Poland.
    Nicotiana africana carries resistance to Potato Virus Y, including a highly virulent necrotic strain PVYNZ. The species was hybridized with several flue-cured cultivars of N. tabacum, both susceptible and tolerant to the pathogen. An attempt was made to ...

    Cytogenetical studies of the interspecific hybrids of Nicotiana africana with different cultivars of N. tabacum

    DOROSZEWSKA T.; BERBEC A.
    Institute of Soil Science and Plant Cultivation, Dept. of Special Crops, Pulawy, Poland.
    As part of the investigations on the potential of N. africana in tobacco, improvement hybrids of N. tabacum x N. africana of different genomic makeup were studied cytologically. Pairing in F1 hybrids (amphihaploids) was minimal (modal bivalent no. = 0, ...

    Institute of Soil Science and Plant Cultivation, Dept. of Special Crops, Pulawy, Poland.
    Four novel isogenic lines of flue-cured Nicotiana tabacum var. Zamojska 4 with substituted alien cytoplasms of Nicotiana knightiana, N. raimondii, N. amplexicaulis and N. eastii were compared with normal Zamojska 4. The cytoplasm donors belonged to two ...

    Investigations of the hybrids of Nicotiana tabacum L. x Nicotiana africana Merxm

    DOROSZEWSKA T.; BERBEC A.
    Institute of Soil Science and Plant Cultivation, Dept. of Special Crops, Pulawy, Poland.
    N. africana was crossed with diploid and tetraploid N. tabacum to study the wild species' potential as a source of resistance to TSWV. Germinating seeds were obtained from mating female N. tabacum with male N. africana but the seedlings usually ...
