Abstract: Wheat (Triticum aestivum L.) is an important grain and staple food crop, which plays an important role in the economy of Pakistan. Wheat crop suffers a lot of yield loss due to insect pests attack, which affects plant life and grain yield. Cultivation of pest resistant/tolerant varieties is the main method to combat these losses. Among the insect pests the aphid Rhopalosiphum padi is a main destructive pests of wheat crop which cause a considerable damage to wheat production in Sindh Pakistan. The current study focus on different resistant wheat varieties against population of aphid R. padi against aphid under field condition. Results of currant study showed significantly maximum population of R. padi (13.54±2.26/tiller) was recorded on Kiran, followed by TJ-83 11.35±2.12/tiller, Sattar 7.23±1.64/tiller, Mehran 5.08±1.13/tiller, TH-83 4.33±0.98/tiller, NIA Sunder 2.25±0.52/tiller, NIA Amber 2.72±0.60/tiller, Khirman 3.17±0.67/tiller, NIA Sarang 3.61±0.77/tiller, while manimum population was found on TD-1 (1.63±0.40/tiller) genotype respectively. The results indicated that highest yield of wheat genotype was recorded from TD-1 (6249.5 kg) followed by NIA Sunder (4562.1 kg), TH-23 (4343.1 kg), Mehran (4311.5 kg), Khirman (4193.2 kg), NIA Amber (3466.1 kg), NIA Sarang (3306.8 kg), Sattar (2826.2 kg), TJ-83 (2400.5 kg) whereas the Kiran genotypes found lowest (2293.1 kg) yield respectively.
