The field experiment on screening of tomato lines for GBNV infection was carried out Horticultural College and Research Institute, Tamil Nadu Agricultural University and Coimbatore. Totally 25 hybrids/varieties were screened in Rabi season during 2015. None of the varieties/hybrids screened were resistant or immune to GBNV during Rabi season. However, average disease incidence ranged from 7.55 to 25.25 percent indicating moderately resistant to highly susceptible. Tomatoes cultivar namely, PKM-1, PKM-2, PKM-3, VRG-17, VRG-95 and IVRC-1 were found moderately resistant to GBNV recording average disease incidence range is 6.88 to 9.88 and thrips population range from 0-2 per plant. In Sivarna, VRG-89, VRG-155, HAT-20, Co-3, WFM-1, ATL-019, DVR-2, LRC-1, DVRT-2, Yellow fruit, Uttakumari and CE-2004 were found moderately susceptible to GBNV recording average disease incidence range is 10.55 to 13.88 and thrips population range from 2-3 per plant. In CE-12, VRG-90, HN-2, H-24, WFF-1 and CLNR-2 were found susceptible to GBNV recording average disease incidence range is 16.77 to 19.75 and thrips population range from 3-5 per plant were recorded.
