    KT&G Research Institute, Daejeon, South Korea
    Potato Virus Y (PVY), PVY-vein necrosis strain, causes severe damage at growth, yield and leaf quality on flue-cured tobacco in Korea. The development of PVY resistant flue-cured varieties without quality deterioration is therefore urgently desired....

    KT&G Central Research Institute, Eumsung Experiment Station, Chungbuk, South Korea.
    Silicon (Si) is an important element in plant nutrition, although it is not considered an essential element. The role of silicon in leaf growth and hormones responsible for silicon uptake has not yet been determined in tobacco. Burley tobacco ( N....

    KT&G Central Research Institute, Bio-resources Research Center, Suwon, South Korea.
    Effects of N forms in different sources of N fertilizers were assessed by analyzing N contents in soil and flue-cured tobacco ( N. tabacum L. Cv. KF 118). Six kinds of compound fertilizers such as chemical (urea, KNO3), organic, microbial and slow...

    KT&G Central Research Institute, Agro-tech. Research Group, Suwon, South Korea.
    The nicotine converter genotypes of burley tobacco (Nicotiana tabacum L.), which convert nicotine to nornicotine, contain a high amount of nornicotine that degrades tobacco quality and smoking taste. Elimination of nicotine converter plants before...

    KT&G Central Research Institute, Agro-tech. Research Group, Chung-Buk, South Korea.
    Tobacco seeds (Nicotiana tabacum L. cultivars 'KF109') were incubated at 18 °C and 23 °C for 32, 36, 40, 44 and 48 hours in a seed container after soaking in water for 36, 42 and 48 hours at 18 °C and 23 °C respectively, and then dehydrated at 30 °C....

    Development of tobacco mosaic virus (TMV) resistant flue-cured F1 hybrid variety KF118

    CHUNG Y.H.; KEUM W.S.
    KT&G Central Research Institute, Agro-tech. Research Group, Suwon, South Korea.
    Tobacco mosaic virus (TMV), TMV-common strain, causes severe damage at growth, yield and leaf quality on flue-cured tobacco in Korea. Controlling TMV outbreak with cultivating practices and chemicals are limited, thus, the best way would be...

    Repellency of herb plants and oils against the green peach aphid, Myzus persicae

    KIM K.W.; JEONG H.C.
    KT&G Central Research Institute, Agro-tech. Research Group, Suwon, South Korea.
    Winged aphids can acquire and transmit PVY within a few minutes. Controlling PVY by insecticides, therefore, is not successful. It may be an effective method of PVY control to repel winged aphids entering tobacco fields. This study was conducted to...

    Inhibitory effects of Acinetobacter sp. KTB3, a bacterial isolate on infection of tobacco mosaic virus in tobacco plants

    PARK E.K.; YEO W.H.
    Korea Ginseng and Tobacco Research Institute, Daejon, South Korea.
    During the screening of antiviral substances having inhibitory effects on tobacco mosaic virus (TMV) infection to tobacco plants, we found a bacterial isolate KTB3, which was identified as Acinetobacter sp., strongly inhibited the formation of TMV...
