The most economic way to manage the foliar blight of wheat is through resistance breeding. The present investigation was carried out to gather information about the hundred entries possessing resistant to spot blotch at field under epiphytotic condition of 2016-17 crop season. Among twenty five entries of wheat, ten entries i.e. GW 322, GW 492, GDW 1255, Raj 4315, Raj 3765, VA 2015-30, VA 2015-41, JD 2015-18, VD 15-26, and VD 2016-1 were found with no infection of foliar blight in all three stages hence their values of AUDPC were zero. While, the highest score of foliar blight were recorded in two varieties; Bansi and A-9-30-1 with 89 and 79 respectively, in hard dough stage. Among barley entries, three entries viz., PL 751, VW 2016-7 and RD 2715 were associated with highest severity score ranging from 69 to 79 so categorized as moderately susceptible to susceptible reaction and their values of AUDPC were ranged from 1605 to 1672.5. Values of AUDPC for all entries were ranged from 0 to 1657.5 as compared to susceptible varieties, Bansi and A-9-30-1 which recorded with AUDPC values of 2122.5 and 1672.5 respectively. It was observed that out of seventy five entries of wheat, fifty eight and nine entries were highly resistant and resistant while among twenty five entries of barley, three and four entries were highly resistant and resistant respectively to foliar blight. Thus, these diverse sources of resistance entries can be used for enhancing crossing programme for developing foliar blight resistant variety of wheat and barley.
