    Nornicotine in industrial varieties of tobacco. I. state of knowledge, follow up of character and efforts to eliminate nornicotine by selection

    FAYEULLE J.P.; DE SALLES DE HYS L.; DUMERY B.
    SEITA, Institut du Tabac, Bergerac, France
    The first part of this article is a revue of the bibliography which gives the main data on nornicotine (reaction of conversion). It is widespread in the Nicotiana genus but its presence is often considered as a cause of defect in industrial tobacco. ...

    Genetic fingerprinting of tobacco by RAPD. Use of markers to screen somatic hybrids between Nicotiana tabacum and Nicotiana rustica L

    COUSSIRAT J.C.
    SEITA, Institut du Tabac, Bergerac, France
    The identification of somatic hybrids between Nicotiana tabacum and Nicotiana rustica can be carried out using polymerase chain reaction (PCR) and four primers of short sequence to direct an amplification of DNA. Each primer amplifies specifically the ...

    Influence of the 5' region non-coding of the potato virus Y on the translation of bicistronic messengers RNA

    CHAYBANI R.; ROBAGLIA C.; CASSE-DELBART F.
    INRA, Laboratoire de Biologie Cellulaire, Versailles, France
    The RNA genome of a group of animal viruses, the picornaviruses, is expressed by an internal initiation mechanism of the translation. The vegetal potyvirus show many structural genomic analogues with the picornaviruses. In this study the influence of the ...

    Production efficiency : effect of plant population, genotype, and N fertilization on yield, quality, and usability

    LONG R.C.; PEEDIN G.F.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    Preliminary studies were begun in 1992 to increase yield/ha, and therefore production efficiency, while minimizing adverse effects on leaf quality. In 1993, treatments in an incomplete factorial design at three locations involved conventional (114 or 122 ...

    Agronomic traits and stability parameters of new flue-cured tobacco hybrids resistant to PVY

    KOZUMPLIK V.; BOIC M.; NEMCEVIC N.; PEJIC I.
    University of Zagreb, Faculty of Agriculture, Zagreb, Croatia.
    Lately, PVY has been the biggest threat to the flue-cured tobacco production in Croatia. Thus, a breeding program with the aim of developing the flue-cured tobacco hybrids resistant to PVY and acceptable to the tobacco producers and cigarette ...
