SUMMARY

Seventy-three sorghum genotypes were evaluated under six field trials for resistance against shoot fly and spotted stem borer along with commercial, resistant, susceptible and local checks at Hisar during Kharif, 2018. Per cent deadhearts caused by shoot fly and stem borer were recorded at 28 and 45 days after emergence, respectively under natural field conditions. Sixteen genotypes viz. SPH 1906, SPV 2581, SPV 2586, SPV 2594, SPV 2530, SPV 2531, SPV2597, SPV 2598, SPV 2604, SPV 2521, AKSV 425, RBSV 34, RBSV 36, SFRM 1, SFRM 2, SFRM 3 and SFRM 4 exhibited resistance against shoot fly as these genotypes produced less than 45 per cent deadhearts caused by Atherigona soccata. However, the genotype SFRM 1 exhibited resistance against both pests including A. soccata and Chilo partellus under natural field conditions.
