Abstract
Chickpea (Cicer arietinum L.), is an important pulse food. During storage this commodity is severely attacked by bean beetle Callosobruchus maculatus (Fabricius) resulting losses in quantity and nutritional quality. Research studies on relative resistance of 12 chickpea genotypes to the attack of C. maculatus during storage were carried out. The genotypes most tolerant to bruchids comprised CH-52/02 and B-8/03, whereas, the most susceptible reactions were apparent in CH-86/02 and CC-117/00. The moderate pest incidence was observed in CH-28/02, CH-4/02, CH-32/02, CH-31/02, CH-9/02, CM-772/03, B-8/02 and CM-628/03 genotypes. The tolerant genotypes exhibited hard and wrinkled seed coat, dark brown colour and small size grain. These characteristics demonstrated a significant harmful effect to pest appearance and grain damage. The vulnerable genotypes had soft and smooth seed coat, white seed colour and bigger grain size that caused vulnerability to C. maculatus. Based on the present investigation, chickpea genotypes CH-52/02 and B-8/03 deserve special consideration and may be recommended for relatively longer storage to achieve the goal of long term and sustainable pest management strategies
