Tomato leaf curl disease is the most devastating disease, caused by tomato leaf curl virus (ToLCV) a Gemini virus transmitted by the vector Bemesia tabaci Gen. In this study 17 F2:3 families of tomato derived from the cross IIHR 2201 x C-13-1-2-1 along with the parents IIHR 2201, C-13-1-2-1 and check Arka Vikas (Succeptible), Arka Rakshak(Resistant) were screened against resistant/ Succeptible reaction for tomato leaf curl disease under field condition, during 2017-18 from end of October to beginning of February in the Department of Vegetable Science, College of Horticulture, Bengaluru. Based on coefficient of infection and per cent of disease incidence, out of 17 F2:3 families only seven families . 18, 29, 64, 88, 144, 253, 261 showed highly resistant reaction, with less per cent of disease incidence and coefficient of infection, and Three families namely 43, 158, 224 showed resistant reaction, five families . 81, 89, 133, 134, 248, showed moderately resistant reaction and only two families 33 and 35 showed moderately succeptible reaction. | Evaluation of F2:3 families of tomato (Solanum lycopersicum L.) for tomato leaf curl disease resistance
