Resistance in tobacco to the tobacco hornworm

Resistance in tobacco to the tobacco hornworm

Journal of Economic Entomology 72(6): 914-915

During the screening of 1500 Nicotiana tabacum cultivars, breeding lines and hybrid populations between 1971 and 1978, 14 were found which seemed to possess a useful degree of resistance to Manduca sexta. Among these forms, compared in a single trial in 1978, a Ti1112 X Ti7 F3 hybrid population and a Ti1112 X McNair 944 F1 were the most resistant. The former showed low damage rates throughout the growing season but the latter only towards the end.
