SUMMARY
Foliar diseases (anthracnose, grey leaf spot, zonate leaf spot) and insect-pests (sorghum shoot fly, stem borer) are major restraints in the cultivation of forage sorghum. Host plant resistance is one of the alternative components to manage sorghum shoot fly, stem borer and foliar diseases. In the present study, sixty-one sorghum genotypes were screened for varied levels of resistance during Kharif 2021 to 2023. Eleven genotypes viz., SPH 1967, SPH 1993, SPH 1994, SPH 1996, SPV 2861, SPH 1997, SPH 2018, SPH 2042, SPH 2043, SPH 2045 and SPV 3045 showed highly resistant disease reaction against sorghum anthracnose and grey leaf spot. Multi-resistance to both shoot fly and stem borer as observed in the entries SPV 2861 and SPV 2955. Entries SPH 1997 and SPV 3046 were found promising against shoot fly, while SPH 1934 and SPH 2047 had least stem borer dead heart formation.
Key words: Sorghum, screening, resistance, foliar diseases, shoot fly, stem borer
