Abstract:
A Laboratory experiment on “Susceptibility of different wheat varieties/ genotypes to lesser grain borer, Rhyzopertha dominica Fabricius” was carried out of at PG research laboratory, Department of Entomology, College of Agriculture, Navsari Agricultural University, Bharuch during 2020-21. Among ten wheat varieties/genotypes (GADW-1, GADW-3, N-820, N- 817, N- 814, N-810, N-807, N-813, N-809, N-811) screened against R. dominica on stored wheat. N-813 and N-809 were found resistant which exhibited minimum seed damage of 25.09% and 25.94%, minimum per cent weight loss of 11.77% and 14.64% and higher per cent germination 58.45% and 53.64% respectively, at 180 days after storage. So far as population build up of R. dominica in varieties/genotypes is concerned, minimum adults (61.33 and 44.47) were emerged in genotypes N-813 and N-809, respectively at 180 days of storage. Variety GADW- 3 and N-811 were found susceptible as it recorded higher seed damage 44.44% and 40.44%, higher weight loss 35.79% and 33.72% and minimum germination 14.30% and 22.69% as well as higher population build up 390.33 and 367.00, respectively.
