The data on per cent damaged grains per panicle due to ear head bug revealed that the varieties viz., GR-104, GAR-1, GNR-3, IR-22, GR-102 and GAR-2 found moderately resistant (MR) with 4-7 per cent grain damage. GNR-2, GR-12, GR-103, GR-7, GR-101, GR-11, Gurjari, Narmada, NAUR-1 and Masuri varieties were categorized as moderately susceptible(MS) group that recorded 8 to 15 per cent grain damage. Whereas, IR-28 found susceptible (S) with 16-25 per cent grain damage and Jaya was categories into highly susceptible (HS) with more than 26 per cent grain damage.
