Evaluation of Tomato (<i>Lycopersicon lycopersicum</i> (L.) Genotypes for their Reaction to <i>Tomato mosaic virus</i> (ToMV) Infection in Kebbi State, Nigeria

Tomato mosaic virus (ToMV) is among the most devastating viral diseases of tomato worldwide and it can cause yield losses up to 40%. One effective managements plant use resistant genotypes. This research was conducted determine reaction genotypes infection. The experiment consists five which were evaluated for resistance ToMV infection under screen-house conditions using Completely Randomized Design (CRD) with three replicates. treatments Dantaya, Danwarai, Dan-Niko, Dan-Heka, Hybrid Platinum, are preferred farmers varieties in Kebbi State. Prior mechanical inoculation, ToMV-infected leaf samples used as source inoculum tested positive Direct Antibody Coating-Enzyme Linked Immunoassay (DAC-ELISA). Thirty-six (36) seedlings each genotype transplanted into plastic pots containing compost recovery recorded two weeks after transplanting (WAT) before inoculation. Platinum has low establishment percentage (72.22%), compared DanHeka Dan-Niko both 100%. All infected when inoculated but significant variation (P = 0.05) their Dantaya highest percent disease incidence 50.00% while, lowest 31.94%. Three susceptible ToMV. high found on State great management concern. Also, this implication productivity state.
