Abstract

Forty desi (local) early maturity chickpea (Cicer arietinum L.) genotypes were screened for resistance to gram pod borer, Helicoverpa armigera (Hubner), under natural field conditions. ICC 506 exhibited 8% pod damage and harboured 10 larvae on 10 plants and was designated as least susceptible, whereas ICC 14665 showed 41.8% pod damage and 26 larvae on 10 plants and categorized as most susceptible. A low amount of acidity in the leaf exudates (21.1 and 41.9 meq./100 gm) of genotype (ICC 14665) was found to be associated with susceptibility to H. armigera, 60 and 75 days afer sowing. However, such a trend was not evident 90 days after sowing.
