| Abstract: |
Maize weevil (Sitophilus zeamais Motsch) is one of the serious insect pests of stored grains of maize in Nepal. Weevil resistant maize is the best option to minimize maize loss in storage. Maize grains of 14 maize genotypes were evaluated for their resistance against maize weevil under free choice test under room conditions. Maize resistance was evaluated based on grain damage index (GDI) value ranging from 0.00 to 1 calculated based on the number of weevils in F1 progeny, rubbish weight from the damaged grains, and weight loss from the sample grains. Non-preference resistance was also tested for the test entries. Among the 14 maize genotypes, seven genotypes were found less damaged (GDI: 0.34-0.49), five were found moderately damaged (GDI: 0.50-0.65), and two were found highly damaged (GDI: 0.66-0.82). The maize genotype ‘Rampur SO3FO4’ was the least damaged one (GDI: 0.34) whereas the genotype ‘RML4 x NML2’ was the most damaged one (GDI: 0.82)…………………… |
