Evaluation of tomato germplasms/cultivars for its comparative level of resistance against tomato fruit borer (Helicoverpa armigera Hubner)

Abstract

Thirty germplasms/cultivars evaluated for their varietal susceptibility/resistance against tomato fruit borer, only Punjab Chhuhara was identified as highly resistant variety of tomato offering maximum protection to fruit damage during both the years of study. The genotypes like TLBRH-6, Hissar Anmol, Kashi Amrit and Punjab Keshari were found moderately resistant, whereas, Kashi Vishesh, Pusa Rubi, Punjab Upma and Avinash-2 were susceptible against fruit borer infesting 10.10 to 15.00 per cent fruit damage and the remaining twenty one cultivars/cultures were graded highly susceptible to fruit borer (Helicoverpa armigera) infestation.
