SUMMARY
Shoot fly is a major insect pest of sorghum and screening for identifying resistant sources against it is a step towards managing it effectively. A total of forty germplasm lines of sorghum were evaluated along with resistant checks (IS 2312, IS 18551 and IS 2205) and susceptible checks (Swarna and DG 6514) during kharif 2020 at Ludhiana and Hisar. Twenty entries were found promising with less than 45% mean dead hearts inflicted by shoot fly. Entry EC- 13 had the lowest mean dead hearts incidence (22.9%) which was comparable to resistant checks. Entries EC-13, E-73, POP- 52 and E-173 had higher leaf glossiness (2.0 to 2.3) along with lesser mean shoot fly infestation ( 30.2% dead hearts). Entries GGUB-34, E-173, E-73, SEB- 12010, ELG-2, EC-12, EC-13, SEVS-2, SEVS-8 and EG- 2 with shoot fly dead hearts less than 45% (17.7- 44.2% dead hearts) were found promising at both the locations.
