Resistance of traditional rice (Oryza sativa L.) genotypes against Asian gall midge (Orseolia oryzae wood-mason) in TBP command area

Abstract

The rice gall midge (Orseolia oryzae Wood-Mason) is recognized as the third most destructive pest, after stem borer and planthoppers. The increased incidence of gall midge may be attributed to the late onset of monsoon and late transplanting during the Kharif season. The current study of screening traditional rice varieties to identify potential traditional rice varietiesagainst rice gall midge was conducted at ARS, Gangavathi in late Kharif 2020. The gall midge incidence i.e. silver shoot was recorded on 30 and 50 days after transplanting. Among 59 traditional rice varieties, Sindhura Madhusaale, Aasanaleeya, and Ralugalli were promising varieties to gall midge incidence with less than 1 percent silver shoot damage. These resistant varieties are further employed in breeding programs and as a one of the component integrated pest management.
