Abstract

Field studies were conducted to evaluate the comparative varietal resistance in thirteen advanced desi chickpea genotypes against chickpea pod borer (CPB), Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) during 2007-2008. Weekly observations showed that mean larval population of CPB in different genotypes ranged from 0.33 to 4.33 per meter row from 1st week of March to 3rd week of April, where the pod damage varied from 7.4 to 14.2%. The results manifest that among the tested genotypes, B 8/02, showed the maximum resistant to CPB along with B 8/03, CH 4/02 and CH 9/02 with highest resistant to CPB, less larval population per plant, minimum pod damage and highest grain yield with increase of 256.8 to 285.7% with respect to check. Therefore, conclude that these genotypes can be used in crossing/evolving new elite chickpea varieties
