Abstract: During the period of 2006-2013 is determined the spread of Tomato spotted wilt virus (TSWV), after analysis of 120 introduced varieties and perspective lines and hybrids of Virginia and Burley tobacco, grown in experimental fields of TTPI (Tobacco and Tobacco Products Institute), Markovo. Results of the study and data from their statistical processing showed that in 2009 and 2010 the spreading of the disease, caused by the virus at the end of the vegetation for Virginia tobacco is twice as high, compared with Burley tobacco. This difference in both varietal groups is mostly expressed in 2007. The variation of results for the spreading of TSWV in Virginia and Burley tobaccos is very large, as the disease is influenced by many factors, mainly the climate, combined in different ways over the years.
