abstract
The present investigation was carried out in randomized block design during kharif 2016-17 at research field, AICSIP, College of Agriculture, Indore (MP). 50 newly developed sorghum genotypes along with two susceptible checks (DJ-6514 and SWARNA) and two resistant checks (IS 2205 and IS 18551) were tested. Shootfly damage at 14 and 28 days after emergence (DAE), leaf injury, dead hearts and stem tunneling percent by stem borer were recorded. The shootfly dead hearts at 14 DAE varied from 8.45% to 81.34% and at 28 DAE it varied from 9.30% to 82.47%. The lowest shootfly attack was recorded in both the resistant check IS 18551 and IS 2205 and in genotypes CSV 15, SPH 1848 and SPV 2324 which showed resistance while SPV 2299, SPV 2305 (SR 2872), SPV 2439, SPH 1858(SS), Swarna and DJ 6514 exhibited susceptibility. The leaf injury caused by stem borer was ranged between 1.41% to 11.16% and infestation at 45 DAE ranged from 10.07% to 55.21%. The lowest damage was recorded in resistant checks and in ICSV 25019, PVK 902 SS, SPV 2434, CSV 15, SPH 1860, SPV 2366 and SPH 1847,the stem tunneling ranged between 1.56% to 8.44% was recorded.
