    Flutriafol residues in non-traditional Burley tobacco

    VANN M.C.; WHITLEY D.S.; CHEEK J.A.; MACHACEK J.L.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Flutriafol is a fungicide that is not currently labelled for tobacco production, which may offer suppression of common foliar leaf spot diseases such as target spot (Rhizoctonia solani) and frogeye leaf spot (Cercospora nicotianae). In spite of such...

    Estimating genetic variability and correlation of agronomic traits in Burley tobacco for selection purposes

    BATISTA E.C.; DE OLIVEIRA E.; FRANTZ E.L.; PULCINELLI C.E.
    Alliance One International, Global Center of Research, Development & Deployment, Brazil
    The breeding values, genotypic and phenotypic variances, heritability and the correlation coefficients of the agronomic traits are some of the key parameters, which determine the efficiency of a breeding program. The phenotypic correlation is...

    Chromosome-level genomes of the Nicotiana tabacum progenitors, Nicotiana sylvestris and Nicotiana tomentosiformis

    SIERRO N.; OUADI S.; AUBERSON M.; DULIZE R.; GUEDJ E.; IVANOV N.V.; GOEPFERT S.
    PMI R&D, Philip Morris Products S.A., Neuchâtel, Switzerland
    As descendants of the Nicotiana tabacum progenitors, Nicotiana sylvestris and Nicotiana tomentosiformis are important diploid Nicotiana species. In addition, ancestors of N. sylvestris were involved in the polyploidization events that gave rise...
