Abstract

The study was aimed to  know the resistance response of some tomato varities to bacterial wilt disease (Ralstonia solanacearum). The study was arranged in a completely randomized design (CRD) with six tomato variety treatmens, namely : Permata, Cosmonot, Idola, Gress, Ratna, and a local Muna variety. Each treatment had three replicates of six plants. The resistance response observed were : the latent period, disease incidence, disease severity,  and  plant  height.  The  response  was   observed  weekly  until  7   weeks  after inoculation.  The  results  showed  that  Cosmonot  variety  was  resistant  to  bacterial  wilt disease, without any disease incedence occured and the disease severity was only 6,66%. Whereas the Local Muna variety as well as Permata, Gress, and Idola were susceptible to bacterial wilt disease. On the other hand, Ratna variety showed slight tolerant response. Keywords : bacterial wilt, Ralstonia solanacearum, resistance reaction, tomato variety
