Abstract
Sixteen chickpea genotypes including susceptible Check BG 362 were screened against gram pod borer, Helicoverpa armigera. The mean larval population of H. armigera ranged from 0.69 to 3.22 larvae per five plants in different genotypes. The lowest larval population was recorded in genotype KPG 59 (0.69 larvae/five plants) and highest in genotype L 550 (3.22 larvae/five plants). The genotype RVG 203 recorded significantly lowest per cent pod damage (5.33%) followed by KPG 59 (6.03%) and BG 212 (9.66%). The genotype L550 recorded significantly highest per cent pod damage (31.33%) followed by BG 362 (24.33%) and GG 2 (23.33%). The genotypes RVG 203 (1840 kg/ha), KPG 59 (1822 kg/ha) produced highest grain yield. The genotype L 550 (8 PSR) recorded significantly highest pest susceptibility rating (PSR) and the lowest pest susceptibility rating was recorded in genotype KPG 59 and RVG 203 i.e 2 PSR � 2022, Journal of Entomological Research.All Rights Reserved.
