Abstract

Thirty three genotypes were screened under field conditions for the fruit borer, Helicoverpa armigera (Hübner) damage for two seasons. The mean of two season for percent fruit borer damage ranged from 3.25 in SL-37 to 70.19 in PAU-101.

As per the scattered diagram, the seven selected genotypes of chilli and capsicum were SL-37, Arka Lohith, Purired, Devarhippargi, TC-1, Button and H.C.-28 and were grouped as resistant. The six genotypes, Hybrid Agni, CA-960, LCA-312, California Wonder, North-Hira and PAU-101 which recorded more than 48.7 percent fruit borer damage were grouped as highly susceptible. The remaining 20 genotypes were rated as susceptible.
