Varietal screening of chickpea, Cicer arietinum (L.) against gram pod borer, Helicoverpa armigera (Hüb.)

Abstract

Fifteen chickpea varieties/genotypes (JG 11, ICCV2, KAK 2, Pusa 391, JGK 1, GJG 3, JG 315, JG 218, JG 63, ICCV 10, Vishal, RSG 888, RSG 44, JAKI 9218 and KPG 59) were screened for resistance to gram pod borer, Helicoverpa armigera in T.C.A., Dholi, Muzaffarpur (Bihar). The population of Helicoverpa armigera was observed on chickpea genotypes from 51 to 114 days after sowing. The overall lowest mean larval population was recorded on Pusa 391 closely followed by RSG 888 during crop season 2017-18. The overall highest mean larval population (4.46) was recorded on JGK 1 which was at par with GJG 3, JAKI 9218, JG 315, JG 63 and JG 218.The maximum per cent pod damage (15.52%) was observed on JGK 1 genotype and minimum per cent pod damage (2.77%) in Pusa 391.
