Impact of awns on grain yield and yield components was studied in two crosses of spring wheat grown under rain-fed conditions. F2 plants were classified into three categories, i.e. awned, awnletted, and awnless. Awned plants in both crosses had significantly higher mean 1000-grain weight and grain yield/plant than the awnletted and awnless categories. For number of spikes/plant, there were no differences among various categories. Regarding number of grains/spike, results differed between the two crosses. Contribution of awns toward grain yield was found to be 20. It is advocated that the awned character be given due consideration in selecting for yield under rain-fed conditions
