SUMMARY

Six field trials were conducted to evaluate seventy five sorghum genotypes for multiple resistance against shoot fly and spotted stem borer along with commercial checks, resistant checks, susceptible checks, local check and improved lines for resistance at Hisar during Kharif 2017. 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. Fourteen genotypes namely, SPH 1838, SPV 2444, SPV 2388, SPV 2387, SPV 2522, SPV 2521, SPH 1895, SPV 2530, SPV 2533, SPV 2532, SPV 2383 and SPV 2385 including two commercial checks (SSG 59-3 and CSV 30F) were found to be resistant against shoot fly and stem borer as these genotypes showed less than 45 and 15 per cent dead hearts caused by A. soccata and C. partellus, respectively.
