A 4 x 4 diallel cross of wheat were evaluated for combining ability at Wheat Research Institute, Faisalabad during 2004-05. Data were recorded from F1 generation for plant height, number of tillers plant-1, biomass plant-1, 1000- grain weight, harvest index, number of grains spike-1 and grain yield plant-1. The additive gene effects were operating in plant height, biomass plant-1, number of grains spike-1 and grain yield plant-1 while number of tillers plant-1 and 1000-grain weight were controlled by non-additive gene effects. The genotypes of “Uqab 2000” proved to be good general combiner for grain yield, 1000-grain weight, biomass plant-1, number of tillers plant-1 and plant height. While V-00055 was found good general combiner for grain yield, biomass plant-1, plant height and number of grains spike-1. The cross “SH-02 × Uqab 2000” and its reciprocal and “V-00125 × V-00055” were the best specific combiners for grain yield plant-1 and yield components.
