Abstract: Evaluation of newly brad and released wheat cultivars is critical in formulating production recommendations about a particular cultivars. Nine wheat cultivars ( Nowshera- 96, Sulman-96, and Saleem-2K, Dera-98, Daman-98, Raj', and Naseer 2K, Tatara, and Fakhre Sarhad) released during the past seven years were evaluated at Agricultural Research Institute Tarnab, Peshawar, during 2000-2001 and 2001-2002 crop seasons. A Randomized Complete Block Design with three replicates was used during each year. Each experimental plot had four rows, spaced 0.30 m apart and 3.5 m long. Sowing was done on November 8, 2000 and November 5, 2001, using a seeding rate of 90 kg ha-1. Soil type was clay loam, wherein 120 kg N (half at sowing time and remaining half at flag leaf stage), 90 kg P and 60 kg K ha-1 was applied each year. Highly significant genetic difference were observe among cultivars for biomass, straw and grain yield, spikes m-2, grains spike-1, and 1000 cyrain weight during both years. Cultivars were highly consistent in performance across years for plant height (r= 0.97, P < 0.01), biomass (r = 0.98, P < 0.01), grains spike-1 (r= 0. 99, P < 0. 0 1) and 1000 grain weight (r= 0. 74, P < 0. 0 1). Fakhre Sarhad had consistently out standing performance among cultivars, producing 67 and 69% more biomass, 68 and 63% more straw, and 64 and 79% more grains than the lowest yielding cultivars during 2001 and 2002, respectively. Fakhre Sarhad also produced comparatively more spikes m-2 , and grains spike-1 than other cultivars during both years. Highly significant and positive correlation of plant height vs. biomass (r-> 0, 7 1, P < 0. 0 1), and biomass vs. straw yield (r-> 0. 90, P < 0. 0 1 ) was contributing component ( r-> 0.87, P < 0.02), but relationship among the yield components was not existent.
