Abstract: Twenty genotypes of chickpea were screened for three consecutive years from 2020-21 to 2022-23, to study different biochemical and morphological traits responsible for C. chinensis resistance under laboratory conditions using “No choice” test. Resistance of chickpea genotypes were evaluated on the basis of per cent chickpea seed damage by C. chinensis.
The results revealed that none of the genotype was completely immune to the attack of C. chinensis. Studies of chickpea revealed that among twenty genotypes, Vijay recorded less number of eggs laid (14.00 eggs/10 seed) and lesser per cent adult emergence (33.93%) and prolonged developmental period (31.67 days, respectively). Vijay exhibited minimum seed weight loss (1.33%) with least seed damage (5.33%). While genotype KAK II and Gulak exhibited maximum per cent seed damage (44.00 and 39.75%), seed weight loss (30.50 and 28.50%) and were categorized as highly susceptible cultivar. Genotype Vijay recorded highest total phenol content (1.91 mg/100 g), alpha amylase inhibitor activity (83.19%) and trypsin inhibitor activity (7.62 TIU/mg). Number of eggs laid, number of adults emerged and adult emergence (%) is significantly and positively correlated with seed damage. Total developmental period and seed hardness is significantly and negatively while growth index is significant positively correlated with chickpea seed damage. Biochemical parameters total phenol content, alpha amylase inhibitor activity and trypsin inhibitor activity is significantly negatively correlated with chickpea seed damage. Lower seed damage in genotypes Vijay, JAKI 9218 was attributed due to lower number of eggs, per cent adult emergence, growth index, more developmental period and seed hardness. However, maximum seed damage and seed weight loss in genotypes KAK II and Gulak was due to more number of eggs, per cent adult emergence, growth index and less developmental period recorded in these genotypes. Based on per cent infestation being main index of resistance, variety Vijay was found highly tolerant against pulse beetle, C. chinensis.
