SUMMARY
Eighty sorghum genotypes possessing forage and sweet sorghum characters along with standard resistant, susceptible and local checks were screened for resistance to major insect pests including sorghum shoot fly and spotted stem borer under natural field conditions at Hisar (Haryana), India during rainy season (kharif) – 2019. Per cent deadhearts caused by shoot fly and stem borer were recorded at 28 and 45 days after emergence, respectively, under natural field conditions. Fifteen genotypes namely, RBSV 36, SFRM 4, SFRM-6, SFRM-8, SFRM-9, SPH 1881, SPH 1933, SPV 2669, CSH 24MF, SSG 59-3, CSV 33MF, SPV 2712, SPV 2604, SPV 2692 and CSV 19SS performed better by registering less percentage of deadhearts caused by Atherigona soccata and Chilo partellus.
Key words:Sorghum, screening, insect resistance, deadhearts, stem borer and stalk tunneling
