Abstract

The tomato is susceptible to more than 200 diseases. Tomato spotted wilt virus is one of the most damaging pathogens in tomatoes. Due to its wide spread, TSWV has become an important limiting factor in tomato production worldwide. Most often the virus is spread by Frankliniella occidentalis (commonly known as thrips), tiny insects that act as a vector carrying the virus. After the plant is infected, the virus will spread throughout the plant. Tomatoes showing symptoms of the disease are unmarketable due to severe discolorations. In areas of high infection, the economic losses for farmers are substantial. By developing lines of tomato that have a host resistance to TSWV, it is anticipated that the negative effects of TSWV can be minimized and that economic losses from TSWV will be reduced.
