ABSTRACT
Eight different varieties like QPM, Rampur Composite, RML, Mankamana-4, Arun-2, Across, Deuti and Manakamana-3 were used for varietal screening against maize weevil damage. The research was done in free-choice and no-choice conditions. Deuti variety of maize was the most susceptible variety and grain damage was recorded up to 40% whereas in long term storage condition, Across (44.81%) was the most suitable variety for weevils. The RML variety of maize was the least damaged variety and loss recorded about 18.12% in 60 days of observations. But while calculating the weight loss of the weevil, the loss 7.66% recorded in 60 days of observation in Across Variety, 6.26% in 40 days of observation in QPM and 5.06% were recorded in Deuti, whereas the lowest percent weight loss was recorded in Manakamana-4 that was 1.80% and 1.00 % in 40 days and 60 days respectively. Maximum number of F1 progenies were observed in across (74.00) and lowest were emerged in Rampur composite (32.33) and RML (32.67). The lowest germination loss was recorded in QPM (8.00%), followed by Rampur Composite (10.00%) and RML (12.67%) respectively.
