Abstract

In order to develop rice cultivars for resistance to the gall midge, Orseolia oryzae (Wood-Mason), some rice entries were screened under natural field conditions at the Chiplima, OUAT, Odisha under All India Coordinated Rice Improvement Project during kharif 2016. Gall midge incidence as silver shoot was recorded on 30 and 50 days after transplanting and scoring was done. Highest incidence of silver shoot was recorded in TN-1 (36.71% SS after 50 DAT) whereas 12 entries viz., W 1263, INRC 3021, Sudu Hondarawala, PTB 26, RP 4686-48-1-937, RMSG-11, WGL 1147, WGL 1127, WGL 1121, WGL 1131, WGL 1141, JGL 27058 were found resistant to gall midge damage. Based on the reaction of the different entries the presence of biotype 1 was identified.
