Abstract
A total of 119 genotypes of chickpea from NBPGR were screened against gram pod borer, (Helicoverpa armigera Hubner) (Lepidoptera: Noctuidae) for four years (2004–05 to 2007–08). The mean incidence of pod borer on the promising genotypes, IC 269317, IC 268855, IC 269218 and IC 269347 ranged from 11.24 to 14.23% as compared to 21.36, 21.53, 23.94 and 35.4% on the check varieties PBG 1, L 550, GPF 2, and the Infester, respectively. The mean Pest Resistance Rating (PRR) was 3 on the promising genotypes whereas it was 4 on check varieties and 6 on the Infester. Genotype IC 269347 gave high yield comparable to check varieties.
