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, Forty three sorghum genotypes were screened for varied levels of resistance during Kharif 2018 and 2019. Eleven genotypes viz., SPH 1881, SPV 2564, SPH 1890, SPH 1891, SPV 2445, SPV 2451, SPH 1917, SPH 1918, SPV 2581, SPV 2591 and SPV 2593 showed highly resistant disease reaction against sorghum anthracnose. Entries SPH 1905, SPV 2587 and SPV 2451 with 17.8, 17.0 and 27.1 percent deadhearts caused by shoot fly (Atherigona soccata). The percent deadhearts caused by spotted stem borer Chilo partellus were ranged between 3.5- 7.8. Overall, SPV 2587 recorded lesser oviposition, least percent deadhearts, low seedling vigour and higher glossiness.
