    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

    VERRIER J.L.; WIERNIK A.; STAAF M.; ONILLON M.; LAURENT T.
    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 ...

    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 ...

    Overview of tobacco variety evolution in France 1989-2005 and impact to the raw matter characteristics

    Altadis - Institut du Tabac, Bergerac, France
    From 1989 to 2005, the French tobacco crop evolved dramatically. A near complete disappearance of dark air-cured types was accompanied by a substantial increase in flue-cured and Burley. Varieties from foreign origin were lacking appropriate adaptation ...

    Evaluation of resistance to the tobacco cyst nematode complex (Globodera tabacum) in the genus Nicotiana and the species Nicotiana tabacum L

    VERRIER J.L.; CAILLETEAU B.; DELON R.; MUGNIÉRY D.
    Altadis - Institut du Tabac, Bergerac, France
    Cyst nematodes from the complex species Globodera tabacum (GT) affect tobacco in Europe and U.S.A. In France, damages have been recorded in the Garonne valley and adjacent areas (south west), since at least 1985. Several Nicotiana species and N. tabacum ...
