Pod borer is the most important chickpea pest which cause a lot of damage annually. Chloridea viriplaca is the dominant species of this pest in Kermanshah. Objective of present study was to evaluate reaction of 22 genotypes (6 genotypes from ICRISAT and 16 advance lines from Iran) to pod borer pest. This experiment was conducted in randomized complete block design (RCBD) with three replications during 2005-2006 in Sararood station, Kermanshah , Iran. Each plot consist of 3 rows with 4 m length.Infestation precent of genotypes to podborer was calculated and resistance and susceptible . Genotypes scored on the basis 1 to 9. Evaluation was done under natural infestation condition.The density of larvae was determained on 10 plants. Results showed that the max and min density were 5 larvae on Bivanij and 1 on ICCL 87211 ICCL 87315 ICC 12494 Hashem S 96019 Jam X,95TH5K10 Flip, 97-102c, respectively . The mean of density of larvae was 2 on 10 plants. The mean infestation of percentage on pods were 6.3 and the max and min infestation of percentage on pods were 14.3 percentage on Bivanij and 6.4 on X95TH5K10 respectively . Finally,The result of present study showed that 8, 12 and 2 genotypes were resistant, moderate and susceptible to pod borer, respectively.
