A field experiment with three replications was conducted at two locations of College of Forestry, Ranichauri, Tehri Garhwal, V.C.S.G. Uttarakhand University of Horticulture and Forestry. One location selected was at Plant Breeding Block (2100-2200 m above msl) and other at Gaja Research Station (1600-1`700 m above msl) for the screening of barnyard millet germplasm in Advance Varietal Trial against per cent damage caused by shoot fly and stem borer during Kharif 2017 under ICAR- All India Coordinated Research Project on Small Millets. The screening comprised a total of 06 entries in Barnyard Millet- Advance Varietal Trial (BAVT) along with two checks viz., VL-172 and PRJ-1. Significant differences in resistance were found in the tested entries to both the recorded insect pests at both the locations. However, the damage recorded at Gaja Research Station was comparatively higher for both the insect pests. The results revealed that due to shoot fly infestation, the percentage of noted ‘Dead Heart’ was in the range of 5.28 to 23.18 per cent at Plant Breeding Block and 7.22 to 25.00 per cent at Gaja Research Station. However, the infestation due to stem borer ranged from 2.91 to 16.63 per cent at Plant Breeding Block and 4.07 to 22.96 per cent at Gaja Research Station. Among the tested entries in BAVT, two entries were found resistant to shoot fly and three entries were found resistant to stem borer. Overall two entries viz., DHBM 996 and TNEF-204 were found resistant to both the insect-pests at both the locations. These experiments conclude that screening of barnyard millet entries in AVT for identifying resistance sources to shoot fly and stem borer is a vital study as entries with stable resistance are of immense value to the breeders and may be used in further breeding programme in developing resistant varieties against both the insect pests.
