Abstract
Among 20 chickpea genotypes, a wide range of variation observed in Helicoverpa armigera larval population (0.99 to 2.02 larvae per plant), pod damage (4.37 to 10.50 per cent), damage rating (1.17 to 1.75), trichome number (105.4 to 279.6 per 0.25 cm2) and grain yield (12.21 to 24.48 q per ha), respectively. The lowest larval population (0.99 per plant), pod damage (4.37 per cent), damage rating (1.17) and maximum trichome number (279.6 per 0.25 cm2) as well as grain yield (24.48 q per ha) was observed in JG-11 which indicates that it is resistant against H. armigera compared to resistant check i.e. ICCL-86111, due to its virtue of genetic potentiality. While the maximum larval population (2.02 per plant), pod damage (10.50 per cent), damage rating (1.75) and lowest trichome number (105.4 per 0.25 cm2) was observed in ICCV-95334, respectively; and lowest yield was recorded from the genotype, ICC-3137 (susceptible check) i.e. 12.21 q per ha . On basis of H. armigera larval population and pod damage, two chickpea genotypes viz., JG-11 (0.99 larvae and 4.37 per cent per plant) and ICCV-97105 (1.15 larvae and 4.91 per cent per plant) were found to be resistant against H. armigera.
