Tomato yellow leaf curl (TYLCV) is most the dreaded disease which causes yield losses up to 90 per cent in tropical and subtropical countries. The disease is transmitted by white flies (Bemisiatabaci). It is imperative to identify TYLCV resistant sources which could be incorporated in tomato improvement programme. The research work was carried out which resulted in identification of new resistant sources. Three highly resistant (null) and five highly resistant lines were reported out of 30 lines and CLN-3125 and Pusa Ruby were taken as a resistant and susceptible checks, respectively. The seedlings were transplanted 21 days after sowing in Randomized Block Design with three replications. The data were recorded for the characters like marketable fruit yield (t/ha), fruit set (%), average fruit weight (g), virus infected plants (%) for three consecutive years. Transplanting after 77 days in the field, the lines NTL-628, NTL-630 and M-108 were found to be highly resistant (null)and NTL-753 (6.89%), NTL-759 (7.55%), NTL-769 (9.25%), M-54 (6.66%) and M-134 (3.55%) were found to be highly resistant. The remaining lines and susceptible check showed high degree of infestation. The resistant lines were confirmed by inoculating virulent white flies under insect proof net.
