Screening of Chickpea Genotypes for Resistant against Pod Borer, Helicoverpa armigera Hubn.

Fifty genotypes of chickpea were screened against gram pod borer under field condition. Each genotype was sown in two rows of 2 m length in Augmented Design, Susceptible (H82-2) and resistant (C235) genotypes as checks were sown after every 10 genotypes. The populations of larvae of grampod borer were recorded on each test genotype at 50% pod filling stage. On the basis of pod damage throughpod borer were grouped in three categories (Tolerant, Moderate resistant, Susceptible). Nine genotypes registered as rating scale 1 were graded as tolerant because their pod damage (5.50–8.50 per cent) were moderate between resistant and susceptibleand these were DGP 15, GIG 0312, ICCL87315, ICCV7, RIL115, ICC29, ICC12470, ICCV 10 and PG23. Seven genotypes (DGP 15, GIG0312, ICCL87315, ICCV7, RIL115, ICC 29, ICC 12470,ICCV10 and PG23) had showed pod damage varies from 20.00–23.00 percent and rating scale 3 were placed under susceptible grade because they were at par with check susceptible (H82-2), remaining 34 genotypes had showed pod damage varies from 10.50–1900 percentrating stage scored 2, were placed under moderately resistant grade.
