Title: Assessment of Tomato Germplasm for Resistance to Fruit Borer<i>Helicoverpa (=Heliothis) armigera</i>Hubner
Abstract: Abstract Identification, exploitation and utilization of host plant resistance are ecologically safe and economically viable strategies for management of the fruit borer, Helicoverpa (=Heliothis) armigera Hubner (Noctuidae: Lepidoptera) in tomato (Lycopersicon esculentum Mill). Three hundred and twenty-one accessions of tomato including cultivars and wild types were screened for resistance against fruit borer, H. armigera in a glasshouse and under field conditions at Annamalai Nagar, Tamil Nadu, India. Ten accessions found promising, along with a susceptible check, were selected for screening under field conditions to confirm their resistance, and plant height, fruit weight, number of fruit and yield were measured. Accessions ‘Varushanadu Local’, ‘Seijima Jeisei’, ‘PT 4287’, ‘Roma’ and ‘Ac 238’ were determined to be highly resistant to H. armigera. Accessions ‘Varushanadu Local’, ‘PT 4287’ and ‘Seijima Jeisei’ may be used as donors of resistance in future breeding programs, but accessions ‘Roma’ and ‘Ac 238’ are recommended for commercial cultivation, as they possessed insect tolerance as well as higher yield.
