Abstract
Tomato genotypes viz., Roma Local, Rio Grande, Tanja, Chico III, Long Tipped, Red- Top, FS-8001, FS-8002,
Tropic, Pakit, Peelo, NARC-1, Roma VFN, Pant Bahr, Ebein, Nova Mech, Rockingham, Nagina, Shalkot-96,
Pomodoro, Manik, Gressilesse, Nadir, Early Mech, Tommy, Pusha Rubi, Tropic boy, Big Long, Sahil, Sun 6002,
Money-Maker and Royesta were evaluated to screen out the suitable resistamt/susceptible genotypes against
the fruit borer in Pakistan. The results imparted that the percentage of fruit infestation and larval population per
plant on tested genotypes of tomato varied significantly. Roma VF, NARC-1 and FS-8002 were categorized as
susceptible genotypes with fruit infestation (37.69%, 37.08% and 36.41%, respectively) and larval population per
plant (1.02%, 1.02% and 0.84 %, respectively). Whereas, the genotypes Sahil, Pakit and Nova Mecb had fruit
infestation (12.30%, 13.14% and 13.96%, respectively) and larval population per plant (0.42%, 0.42% and 0.43%,
respectively) and declared as resistant genotypes to tomato fruit borer. Lower values of host plant susceptibility
indices (HPSI) were recorded on resistant genotypes. Sahil, Pakit and Nova Mecb could be used as a source of
resistance for developing tomato genotypes resistant to tomato fruit borer.
