Abstract
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 F, generation for plant height, number of tillers plant", biomass plant", 1000-
:: grain weight, harvest index, number of grains spike" and grain yield plant". The additive gene effects were
operating in plant height, biomass plant", number of grains spike" and grain yield plant' while number of tillers
plant" 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", number of tillers plant" and plant
height. While V-00055 was found good general combiner for grain yield, biomass plant", plant height and number
of grains spike". The cross "SH-02 x Uqab 2000" and its reciprocal and "V-00125 x V-00055" were the best
specific combiners for grain yield plant" and yield components
