    Comparison of the degree of malformations in different breeding materials carrying Nicotiana alata-introgression conferring resistance to tomato spotted wilt virus

    TROJAK-GOLUCH A.(1); KORBECKA-GLINKA G.(1); DOROSZEWSKA T.(1); GOEPFERT S.(2)
    Institute of Soil Science and Plant Cultivation - State Research Institute, Pulawy, Poland
    Tomato spotted wilt virus (TSWV) has been an important problem in tobacco cultivated in a moderate climate zone. The transfer of RTSW-al (TSWV resistance gene) from Nicotiana alata to the N. tabacum genome and the development of Virginia-type cultivars is ...

    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 ...

    Tobacco breeding for TSWV resistance using RTSW-al factor derived from cultivar Polalta

    TROJAK-GOLUCH A.(1); KORBECKA-GLINKA G.(1).; GOEPFERT S.(2); DOROSZEWSKA T.(1).; BERBEC A.(1)
    (1) Institute of Soil Science and Plant Cultivation - State Research Institute, Pulawy, Poland; (2) Philip Morris Products S.A. (part of Philip Morris International group of companies), Neuchâtel, Switzerland
    Tomato spotted wilt, caused by the tomato spotted wilt virus (TSWV), causes significant economic losses in the cultivation of tobacco worldwide. The best approach to the management of the disease is growing resistant cultivars. Within N. tabacum, the only ...

    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 ...

    Phylogenetic analysis of PVY isolates

    PRZYBYS M.; DOROSZEWSKA T.; KORBECKA G.
    Institute of Soil Science and Plant Cultivation - State Research Institute, Pulawy, Poland
    Potato virus Y (PVY) is an important pathogen of tobacco. It belongs to the Potyvirus genus in the plant virus family Potyviridae. In this study, a collection of fifteen PVY isolates from tobacco, originating from fields in Poland, Germany and Croatia, ...

    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 ...

    Sources of resistance to viral diseases within the genus Nicotiana

    DOROSZEWSKA T.; DEPTA A.
    Institute of Soil Science and Plant Cultivation - State Research Institute, Pulawy, Poland
    Viral diseases cause important economic losses in tobacco crops. They are transmitted by vectors or mechanically, and the battle is difficult due to the lack of chemicals that eliminate them. The most damaging viruses that affect tobacco in Poland are ...

    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 ...
