Abstract

Amongst 100 chickpea genotypes screened against Helicoverpa armigera, IC 11627 recorded the lowest larval population (0.60 larvae/5 plants), lowest percent pod damage (6.50%), and highest yield of chickpea (1.73 t/ha). Based on PRSR (Pest resistance susceptible rating), 18 genotypes (IC 11627, EC 198581, IC 538496, IC 5522, IC 2722278, IC 275637, IC 48746, IC 299175, IC 257477, IC 299330, IC 305597, IC 299218, IC 327579, IC 9862, IC 9755, ICC 14402, ICC 4182, & ICCL 86111) showed scale 3 ratings and were categorized as ‘Resistant’.
