Eighteen chickpea (Cicer arietinum L.) genotypes were evaluated for yield and their susceptibility reaction against gram pod borer, Helicoverpa armigera Hub. for three consecutive years under natural field conditions during rabi 2010-11, 2011-12 and 2012-13 at Hisar. Among these, maximum grain yield was realized from the genotype H 04-28 (13.00 q/ha) during the season rabi 2010-11 and it was statistically at par with RSG 931 (12.45 q/ha), H 03-56 (11.73 q/ha) and RSG 963 (10.82 q/ha) during rabi 2011-12 and it was statistically at par with GNG 1488 (10.01 q/ha), CSJ 140 (9.07 q/ha) and H 03-56 (8.95 q/ha) during Rabi 2012-13 and it was statistically at par with RSG 888 (8.80 q/ha) and GNG 1591 (7.79 q/ha). However, on the basis of average of three years (2010-11 to 2012-13), the maximum yield was exhibited by the genotype GNG 1488 (9.36 q/ha) followed by RSG 931 (8.95 q/ha), H 04-28 (8.32 q/ha) and H 03-56 (8.20 q/ha). The genotype H 03-56 flowered earliest in 68-71 days and proved the best donor against gram pod borer with PSR 4.7. Minimum larval population was recorded in BG 256 (15.8 l/mrl) and it was followed by GL 25016 (17.5 l/mrl) and H 04-28 (18.5 l/mrl). Minimum per cent pod infestation by H. armigera was recorded in genotype H 01-27 (27.8%) and it was superior over all other genotypes. It was followed by H 03-56 (29.5%), CSJ 140 (30.9%) and GNG 1488 (31.3%). H 01-27 proved least susceptible genotype under natural field condition. The genotype H 03-56 flowered earliest and seemed to be the best as potential donor for pod borer’s tolerance under late sown condition. GNG 1488, RSG 931, H 04-28, H 03-56 and RSG 963 proved promising genotypes for yield and against H. armigera. These genotypes may further be utilized in breeding programmes to develop the high yielding and tolerant cultivars against gram pod borer.
