    Agronomic performance of cytoplasmic male sterile forms of flue-cured tobacco

    CZUBACKA A.; DEPTA A.; DOROSZEWSKA T.
    Institute of Soil Science and Plant Cultivation - State Research Institute, Pulawy, Poland
    Cytoplasmic male sterility (cms) in many crops is the basis for the production of commercial F1 hybrids. This is obtained by the combination of the nucleus of cultivated species with the cytoplasm of a wild species belonging to the same genus. The reason ...

    Influence of PVY infection on chemical composition of tobacco

    PRZYBYS M.; CZUBACKA A.
    Institute of Soil Science and Plant Cultivation - State Research Institute, Pulawy, Poland
    Potato virus Y (PVY) is the type member of the genus Potyvirus in family Potyviridae. PVY has a worldwide distribution and is one of the most economically important viruses in tobacco. PVY causes limitation of assimilation, gas exchange, inhibition of ...

    Effectiveness of combining potato virus Y tolerance and resistance determined by transgenes in tobacco

    CZUBACKA A.; KORBECKA G.; OLSZAK-PRZYBYS H.; DOROSZEWSKA T.
    Institute of Soil Science and Plant Cultivation - State Research Institute, Pulawy, Poland
    Growing resistant cultivars is the most effective method of plant protection against viral diseases. Different sources of resistance are used for breeding new tobacco cultivars resistant to potato virus Y (PVY). The best source of resistance is Nicotiana ...

    Biological and serological characterisation of PVY isolates from Central Europe

    KORBECKA G.; CZUBACKA A.; PRZYBYS M.
    Institute of Soil Science and Plant Cultivation - State Research Institute, Pulawy, Poland
    Potato virus Y (PVY) is one of the most important viruses affecting tobacco. It is an RNA virus with a high mutation rate due to error-prone polymerase and a lack of proof reading mechanisms during replication. A high variability of this virus increases ...

    Mapping introgression determining potato virus Y (PVY) resistance transferred to cultivated tobacco from Nicotiana africana

    KORBECKA G.; CZUBACKA A.; DEPTA A.; OLSZAK-PRZYBYS H.; DOROSZEWSKA T.
    Institute of Soil Science and Plant Cultivation - State Research Institute, Department of Plant Breeding and Biotechnology, Pulawy, Poland
    Potato virus Y (PVY) is one of the most important pathogens affecting tobacco. Since this virus infection cannot be effectively controlled by eliminating its vectors, the main effort of disease prevention is concentrated on breeding tobacco for resistance ...

    Effectiveness of transgenes in protection against potato virus Y in tobacco breeding lines

    CZUBACKA A.; DOROSZEWSKA T.
    Institute of Soil Science and Plant Cultivation - State Research Institute, Pulawy, Poland
    Progress in genetic transformation techniques has allowed successful production of transgenic plants with improved traits. However, it is important that introduced genes are stably inherited and expressed. Three tobacco transgenic lines coming from ...

    Determination of resistance to potato virus Y and its stability in tobacco hybrids containing different sources of resistance

    CZUBACKA A.; DOROSZEWSKA T.
    Department of Plant Breeding and Biotechnology, Institute of Soil Science and Plant Cultivation – State Research Institute, Pulawy, Poland
    Cultivation of resistant cultivars is the most effective method of plant protection against viral diseases. Different sources of resistance are used for breeding new tobacco cultivars resistant to potato virus Y (PVY). Currently three main sources of ...

    Evaluation of agronomic characteristics of transgenic tobacco doubled haploids

    CZUBACKA A.; DOROSZEWSKA T.
    Institute of Soil Science and Plant Cultivation, Dept. of Special Crops, Pulawy, Poland.
    Transgenesis allows the modification of plant genomes relatively quickly and precisely. Moreover, compared with classical methods, genetic transformation significantly facilitates and shortens the time needed for breeding a new cultivar. Shortening a ...

    Obtaining resistant to PVY tobacco double haploids containing different sources of resistance

    CZUBACKA A.; DOROSZEWSKA T.
    Institute of Soil Science and Plant Cultivation, Dept. of Special Crops, Pulawy, Poland
    Tobacco veinal necrosis- a disease caused by Potato virus Y (PVY) influences adversely the tobacco yield. Within the genus Nicotiana there are some sources of resistance to the virus but none of them is effective to all isolates. Therefore, for increasing ...
