Screening of different wheat varieties against aphids at Pantnagar

Ashish Devrani, RS Bisht and Nistha Rawat

Study was carried out in the department of entomology, GBPUA & T, Pantnagar (2015-16). Lowest aphid population were found in PBW-660 (1.9 aphids/plant) and highest aphid population was found in UP-2785 (4.96 aphids/plant) during 30 DAG. In the genotypes UP-2526 (8.86 aphids/plant) and DPW-62150 (26.46 aphids/plant) recorded lowest and highest aphid population at 45DAG respectively. At 60 DAG UP-2785 and UP-2785 genotypes recorded the lowest (1.50 aphids/plant) and highest (4.96 aphids/plant) aphid population was recorded respectively. The genotype UP-2526 and UP-2869 were comparatively resistant with minimum population of aphids (4.30/plant and 5.83/plant). Whereas, the genotypes DPW-62150 (11.98 aphids/ plant) found susceptible. As the genotype UP-2869 and UP-2526, has lowest aphid population shows the highest yield of 21.00q/ha. DPW-62150, UP-2425, HD-3059, WH-1105 and UP-2883 with highest aphid population (11.98, 10.93, 10.72, 10.06 and10.02 aphids/plant) shows the lowest yield of 15.50q/ha, 17.50q/ha, 17.50q/ha,17.00q/ha and 16.00 q/ha.
