Fourteen genotypes of chickpea (Cicer arietinum L.)namely CSJ 859, CSJ 870, CSJ 855, CSJK 46, Phule G 13107, Phule G 12313, GL 12021, GL 29095, GNG 1969, NBeG 49, JG 11, ICCL 86111 (resistant check), ICC 3137 (susceptible check) and JG 14 (local check) were evaluated to study the ovipositional preference of Helicoverpa armigera during 2016-17 and 2017-18. The experiment was conducted in completely randomized design in the laboratory, adopting free-choice experiment technique. Twenty eight pairs (males & females) of adults of H. armigera were released in the cage containing chickpea genotypes, for mating & oviposition. Preference of adult females for oviposition was determined based on total egg count on different genotypes. Lowest mean oviposition was observed on genotypes NBeG-49 (11.67 eggs/ plant) and ICCL-86111 (13 eggs/ plant). Next better genotypes were CSJ-870 and Phule G-13107 (18 eggs/ plant).
