Abstract

Eight chickpea genotypes were evaluated against the infestation of Helicoverpa species under the field conditions at NIA, Tandojam. Helicoverpa species were the most serious insect pests causing severe damage to this crop. In order to identify resistance against the infestation of this pest, seeds of the test genotypes were obtained from Plant Genetics Division of this Institute. Results depicted that all the genotypes showed varied response to the traits under observation. The data on larval population, percentage damage and yield components was highly variable, showing the percentage larval attack severity 1.00 to 50.00, pods damage 8.50 to 90.90% and 23.33 to 1920.00 gm grain yield of the sampling unit. Data revealed that genotype C-727 was relatively resistant against pod borer infestation as compared to other genotypes.
