ABSTRACT

Pod borer (Helicoverpa armigera) is economically vital insect pests for chickpeas and caused huge yield losses in south Asian countries. Host plant resistance, physio-morphic characters counteract the ability of insect to demage and to cause minimum reduction in yield. The experiment was conducted under natural and semi-natural conditions to determine the host plant resistance of nine (09) chick pea advance genotypes viz., (K01211, K01216, K01241, K01242, K09012, KO1308, K014001, K014002, K-14003) and one (1) control (Noor). Antixenosis was calculated by counting the number of eggs per stem and antibioses was assessed by counting the number of infested leaves and survival rate of pest. The results revealed that H. armigera infestation started to appear during the second fortnight of February that continued to increase till the crop maturity. Lowest number of eggs (115) were recorded on K01308 while K09012 and K01242 were found to be most preferred for oviposition (261 and 250, respectively). Maximum larval survival about 0.98 was recorded on K09012 followed by K01216. Whereas, minimum was recorded on K014001 followed by K01308 and K014002.Minimum leaf damage percentage (1.1289%) was observed in K014001 followed by K014002, K14003 and K01308 however maximum damage (7.25%) was observed in K01242.
