Results revealed that with the increased levels of web blight severity, the corresponding yield decreased significantly. Per plant reduction in seed yield varied from 24.2 to 60.4% under resistant (grade 1) to highly susceptible (grade 9) in comparison to healthy control. On an average 35.6% reduction in seed yield were assessed on moderate level of susceptibility (grade 5) over healthy control. Out of 45 genotypes evaluated against web blight. IPU 8–18, KU 99–19, IPU 7–19, VBG 04–008, OBG 31, IPU 94-1 and IPU 05–13 showed highly resistant reaction with disease score 1. The genotypes viz., CU-5, SB 25–19 IVT, NDU 9–15, UH 4–06, Pant U 30, M 1–1, KUG 222, UL 416, UL 417, KKB 20055 and UH 04-65 showed moderately resistant reaction with disease score 3.
