Abstract
Breeders are always interested in the task of developing new varieties for changing environments. Thus, they have to deal with new crosses to select desired combinations. Grain yield is a complex character that is influenced by the fluctuating behavior of the environment. To overcome this situation, it is necessary to breed wheat varieties which perform better than existing ones under diverse conditions. A complete diallel cross was prepared from eight parental wheat accessions with a range of tolerance to drought. F1 hybrids and parents were grown at Barani Agricultural Research Institute, Chakwal. At maturity peduncle length, number of spikelets per spike, number of grains per spike, dry weight per plant at maturity and harvest index were recorded.
