A 5 x 5 diallel cross experiment on bread wheat revealed that the genetic interactions were apparently of overdominance type for number of tillers plant-I and number of grains spike-I, determining delayed selection to fairly good improvement in these traits. Additive type of gene action with partial dominance and absence of non-allelic interaction was found for lOOO-grain weight suggesting fruitful selection in early generations. There was also additive with partial type of dominance for grain yield but the presence of epistasis showed that selection might be more effective in later segregating generations.
