Abstract:
The field experiments on “Screening of chickpea germplasm against gram pod borer, Helicoverpa armigera Hubner” was conducted at Students’ Instructional Farm of C. S. Azad University of Agriculture & Technology, Kanpur during Rabi 2017-18 and 2018-19. Screening of fifty chickpea germplasm with one check variety KGD-1168 was carried out to evaluate for resistance to gram pod borer, H. armigera. Present study revealed during 48^th SW till maturity i.e. 14^th SW both years. The lowest larval population was recorded of 0.77, 0.71 larvae/m row in germplasm 425 and highest population with 6.72 and 6.01 larvae/m row in germplasm 471 and P-255, respectively. The minimum pod damage was recorded of 4.08 and 4.88 percent in germplasm 425 and W-48-75 and maximum i.e. 14.42 and 13.22 percent was recorded in germplasm 471, P-255, respectively. The insect pest susceptibility rating (PSR), declared that 7 and 8 germplasm were found highly susceptible, 26 and 26 were moderately susceptible and 16 and 15 least susceptible, respectively, both years.
