abstract
The present experiment was conducted during Kharif 2017-18 at the Entomological Research Field, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. In this field trial 9 long duration Pigeonpea genotypes were screened for resistance against Tur Pod bug, Clavigralla gibbosa (Spinola). The first incidence of pod bug was observed in the 4^th standard week in all genotypes and the population persisted up to 12^th standard week in all the genotypes. The peak population of pod bug irrespective of the genotype was recorded in 10^th standard week. The mean populations of pod bug on different genotypes ranged from 1.84 pod bugs/plant in CRG 2015-007 to 4.40 bugs/plant in Bahar (Check). The per cent pod damage due to pod bug significantly varied from 14.33 per cent in genotype CRG 2015-007 to 29.00 per cent in genotype Bahar. The highest grain damage by pod bug was also seen in Bahar (8.97%) while the lowest grain damage was observed in CRG 2015-007 (3.85%). The grain yield of different genotypes also differed significantly and ranged from 916 kg/ha in the genotype Bahar to 1500 kg/ha in JKM 189.
