    Breeding for blue-mould resistance in Burley and flue-cured tobacco: an overview of results

    VERRIER J.L.; MALPICA A.; L’HUMEAU J.
    Bergerac Seed & Breeding, Bergerac, France
    Conventional, non-GMO blue-mould (Peronospora tabacina) resistance has been transferred to Nicotiana tabacum L. from interspecific hybridisation works tracing back to years 1965-70, involving in particular the species Nicotiana debneyi. Partial resistance ...

    TSNA accumulation during post-cure storage of air-cured tobacco: Results of a 2009 experiment

    Imperial Tobacco Group, Institut du Tabac, Bergerac, France
    In Burley and dark tobacco, tobacco specific nitrosamines (TSNA) are formed during air-curing. A further accumulation may occur post-cure, before threshing and re-drying. The experiment reported here investigates this post-cure accumulation in leaves from ...

    Contribution of near infra-red spectrometry (NIRS) to detect nicotine conversion to nornicotine in Burley tobacco

    VERRIER J.L.; JOURDAIN M.; VERRON T.
    Imperial Tobacco Group, Institut du Tabac, Bergerac, France
    Discarding converter plants is a major goal in the seed production of Burley cultivars, but requires chemical analysis of individual alkaloids. In order to lessen this workload, we explored the possibilities offered by spectrometry. The LabSpec Pro → ...

    The influence of post-curing handling of Burley and dark air-cured tobacco on TSNA and nitrite levels

    VERRIER J.L.; WIERNIK A.; STAAF M.; CADILHAC J.L.; ONILLON M.; VIDAL B.
    Institut du Tabac, Imperial Tobacco Group, Bergerac, France
    While most of Tobacco Specific Nitrosamines (TSNA) are formed during air-curing, further accumulation may occur between end of cure (EOC) and delivery. In order to investigate putative factors affecting this accumulation, different ways of storing have ...
