Abstract: In order to understand the tomato bacterial wilt resistant resources of genetic background, the field planting method and inoculation method, in all parts of the country's 127 varieties and 208 copies of materials evaluation of resistance to bacterial wilt. The results showed that the death of 127 varieties all patients, only three species received the first red, big source less resistant materials, small fruit more, based on the average incidence of resistance evaluation of grading, small fruit H7997 and cherry fruit T16 not the disease, not the disease; Resistant resources had T17, T8; T4, T6, T7, T381, T390 was the onset of lighter disease.
