Abstract

Forty three inbred lines were evaluated against maize stalk borer, Chilo partellus (Swinhoe) under artificial infestation during khari! (rainy) season and under heavy natural infestation against shoot fly species (Atherigona soccata Rondani and A. naqvii Steyskal) during spring season. The persual of data reveals that two inbreds namely, IPA 34 - 10 - 13 - 3 - 1 - 1 - # - 2 - 1 and IPA 3 - 6 - 14 - 2 - # - 1 were least vulnerable to both the tissue borers, C. partellus and Atherigona spp. These inbreds may be designated as multiple pest resistant sources and should be used while developing varieties or single/double cross hybrids.
