The present investigation was carried out in randomized block design during kharif 2016-17 at research field, AICSIP, College of Agriculture, Indore (MP). The ear head bug population ranged between 3.00 to 12.67.The lowest number of pest was recorded in resistance check IS 18551 (3.00) followed by IS 2205 (3.67), AKSV 410 (4.00), RSSV 350 (4.00), SPV 2433 (4.00), IS 2123 (4.00), SPV 2426 (4.33), SPV 2440 (4.33), SPV 2358 (4.67), CSV 27 (4.67), SPH 1862 (4.67) and SPV 2308 (4.67) and showed resistant against the insect. However, susceptible checks DJ 6514 (11.00) and Swarna (12.67) recorded maximum number of bug. The ear head worm population ranged between 3.67 to 13.00. The lowest number of ear head bug was recorded in resistance checks IS 2205 (3.67) which was statistically found to be at par with CSV 27 (4.33), SPH 1862 (4.33), SPV 2293 (4.67), SPV 2432 (4.67) and SPV 2305 (SR 2872) (4.67) and showed resistant against the insect. However, susceptible checks Swarna (11.33) and DJ 6514 (13.00) recorded maximum number of worms. Under yield attributing characters number of grains per ear head ranged from 733.79 to 1370.37, and yield in kg/ha. have been obtained between 3672 to 6594(kg). The maximum grain yield in (Kg/ha.) was obtained in genotype SPV 2299 (6594) and found significantly superior with rest of the genotypes.
