The present study was under taken on the varietal screening against pod borer Helicoverpa armigera in Pigeonpea at Rainfed areas of Kabirdham district under the SK College of Agriculture and Research Station, Kawardha, Indira Gandhi Krishi Vishwavidyalaya Raipur (Chhattisgarh) India. During 2008-2009 crop season ten selected pigeonpea genotypes viz.. BDN-2, UPAS-120, RPS-2007-63, Asha, RPS-2007-107, Rajeev lochan, RPS-2007-73, ICPL-87, RPS-2007-15 and RPS-2007-109 were tested against pod borer in the field conditions. The Number of pods per plant, Grain yield per plot and Grain yield kg/ha. Among genotypes, RPS-2007-109 recorded significantly highest pod damage and lowest pod damage was recorded on RPS-2007-73. The losses in yield due to infestation by pod borer Number of pods per plant was height recorded in the genotypes UPAS-120, Grain yield per plot (Kg/plot) and Grain yield kg/ha was height recorded in the genotypes BDN-2.
