SUMMARY
Forty six sorghum genotypes along with resistant, susceptible and local checks were screened for resistance against shoot fly and spotted stem borer at Forage section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar during Kharif, 2019. Per cent dead hearts caused by shoot fly and Stem borer were recorded at 28 and 45 days after emergence respectively, under natural field conditions. Nine genotypes namely, CSH 40F, CSV 21F, SPV 2704, SPV 2591, SPV 2582, SPV 2587, SPV 2581, SPV 2584 and SPV 2593 showed resistant in terms of minimum per cent dead hearts caused by Atherigona soccata and Chilo partellus.
