Evaluation of chickpea (Cicer arietinum L.) genotypes against gram pod borer (Helicoverpa armigera, Hubner) under field conditions

Abstract

Fourteen genotypes of chickpea (Cicer arietinum L.) namely CSJ 859, CSJ 870, CSJ 855, CSJK 46, Phule G 13107, Phule G 12313, GL 12021, GL 29095, GNG 1969, NBeG 49 and JG 11 including resistant check (ICCL 86111), susceptible check (ICC 3137) and local check (JG 14) were evaluated against Helicoverpa armigera through field screening trials during the years 2016-17 and 2017-18. The trials were conducted in Randomized Block Design with three replications. Larval density of Helicoverpa armigera was recorded on different genotypes at regular intervals during vegetatve, flowering and maturity stages of the crop. Pooled data analysis indicated lowest seasonal mean population density of H armigera on genotypes CSJ-870 and CSJ-855 (0.41 and 0.48 larva / 0.5 m2, respectively).
