Description Biparental progenies (North Carolina Design II) derived from F2s produced separately from normal parents and the same parents treated with EMS (0⋅4%) were analysed for estimating components of genetic variances for yield and certain yield components in bread wheat. Additive genetic variance constituted the major source of variation for all the component characters except tillers/plant which along with yield showed greater importance of dominance component. Diversity of parents influenced the estimates; genetic variances were higher in the cross which involve diverse parents. Mutagen treatment increased the additive genetic variance for all the characters except test weight whereas nonadditive genetic variance varied in a random fashion. In self pollinated cross, such as wheat, it is encouraging that additive genetic variance were predominant and thus could be exploited most effectively by resorting to population improvement approach
