Abstract

Laboratory experiments were carried out to evaluate twenty genotypes of chickpea against pulse beetles (Callosobruchus chinensis (L.) for three consecutive years from 2020-21 to 2022-23. Twenty genotypes/varieties of chickpea were used to characterize their resistance against pulse beetle by using “No choice” test. Resistance of chickpea genotypes was 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. Susceptibility 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. Lower seed damage in genotypes Vijay, JAKI 9218 was attributed due to lower number of eggs, per cent adult emergence, growth index and more developmental period. 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

Conclusion

From the above investigation it is concluded that, Vijay chickpea variety can be effectively used as promising donors for developing bruchid resistant varieties which would ensure food security by reducing postharvest losses under storage conditions
