  • Burley tobacco (Nicotiana tabacum L.) KB 108 was developed from a single cross between KB 104 and TC 591 which was developed from a cross between Burley 49 and Tobacco Introduction 1406. It was tested for its resistance to black shank, potato virus Y(PVY), TMV and agronomic characteristics under field conditions. KB 108 has resistance to tobacco mosaic virus(TMV) and necrotic strain of potato virus Y(PVY-VN) with secreting glandular trichomes. It has also moderate resistance to black shank caused by phytophthora parasitica val. Nicotianae. KB 108 has an up-right plant growth habit similar to Burley 21. It flowers about 1-2 days later than Burley 21. The leaf width and length of KB 108 are approximately 3 cm wider and longer than those of Burley 21. The yield of KB 108 was higher 4%, nearly equal in value per kg compared to Burley 21.

  • In order to obtain the basic information for the successful breeding of aromatic tobacco (Nicotiana tabacum L.), the heterosis, combining ability and gene distributions in 28 Fl hybrids by diallel crosses between Korea local and Oriental varieties were investigated. The yield were higher, stalk height, leaf length and leaf width were larger and days to flower was shorter for the Fl hybrids when compared to mid-parent. Estimates of general combining ability were significant for all characters investigated, and specific combining ability were significant for yield, stalk height, leaves Per Plant, leaf width and days to flower. In vr-wr graph, partial dominane was exhibited by all characters investigated.

  • Transgenic Nicotiana benthmiana plants harboring and expressing coat protein (CP) gene of Zucchini green mottle mosaic virus (ZGMMV) were generated for both virus-resistant screening and complementation analysis of related viruses and environmental safety assessment (SA) of living modified organism (LMO) purposes. Transformation of leaf disc of N. benthamiana was performed using Agrobacterium-mediated method and the pZGCPPGA748 containing the ZGMMV CP and NPTII genes. Two kinds of transgenic homozygous groups, virus-resistant and -susceptible lines, were obtained by screening of challenging homologous virus for T1 generations. Complementation of CP-deficient related virus was analyzed using the susceptible line of ZGMMV. These two pathologically different lines can be useful for host-virus interactions and LMO environmental SA.
