Chilli veinal mottle virus infection (ChiVMV) could reduce the quality and 60–100% of yield losses of Chili. Among the Chilivarieties released, no one has been resistant to ChiVMV, mainly due to a high variation of ChiVMV strains and not well mapped.Therefore, finding a new source of ChiVMV resistant genes is pivotal role in order to assembly new varieties. Approach throughin vitro mutation induction using mutagen ethyl methane sulfonate (EMS) is one of the efforts to increase genetic diversity.Previous studies has successfully acquired 800 M2 lines through callus induction of Gelora variety with EMS. This study aimed toobtain M2 lines resistant to ChiVMV and having a good agronomical characters. A total of 800 Chili M2 lines that derived from ChiliM2 mutations using mutagen EMS has been tested in greenhouse to ChiVMV resistance and studied character phenotype. Theresults showed that of the 800 lines, there were 28 strains obtained showed a response tolerant and resistant to ChiVMV. Eightmutant lines of which have good agronomic characters. The mutant lines are M2.100, M2.108, M2.200, M2. 122, M2.238, M2.353,M2.420, and M2.517. Eight lines will be selected and further observed to obtain Chili promising lines that are resistant to ChiVMVand high yielding.
