    Genetic study of Erysiphe cichoracearum D.C. resistance of PMR Burley 21 cultivar and some morphological characters that influence the tobacco yield

    TOUNKARA F.; PALAKARCHEVA M.
    Institut of Genetics - Plant Breeding, Sofia, Bulgaria.
    The aim of the present investigation is to study the genetic control of Erysiphe cichoracearum resistance of PMR Burley 21 cultivar, coming from N. tabacum. At the same time the inheritance of some quantitative characters was studied, that influence the ...

    Belgrade University, Faculty of Agriculture, Belgrad-Zemun, Yugoslavia
    In this work, static burning rate (SBR) is taken as the basic indicator of general burning conditions, chosen primarily as a practical one (it can easily be determined). First we have determined SBR for main Yugoslavian tobaccos, their condensate ...

    Differences in composition of particulate phase of smoke condensate caused by addition of fruit concentrates

    NIKOLIC M.
    Belgrade University, Faculty of Agriculture, Belgrad-Zemun, Yugoslavia
    On the basis of gas-chromatographic and mass-spectroscopic analysis differences in the content of three main fractions (weakly acid, neutral, basic) in condensate (CSC) of pure Burley and Burley treated with four fruit concentrates as additives were ...

    Effect of seedling source on incidence of tomato spotted wilt in flue-cured tobacco

    CULBREATH A.K.; BERTRAND P.F.; CSINOS A.S.
    University of Georgia, Dept. of Plant Pathology, Tifton, GA, USA.
    Tobacco seedlings from 16 different outdoor seedbeds in 11 counties in Georgia were assayed by ELISA for tomato spotted wilt virus (TSWV). Only one asymptomatic seedling out of more than 1,200 was positive for TSWV. Additional seedlings from the 16 ...
