Three samples of bread-wheat CV. Ajeeba stored under Baghdad prevailing room conditions since 1968, 1978 and 1983 were irradiated with gamma rays (15 krad). They were then treated with the chemical mutagen (EMS). Seeds were sown in the field during the cultivation seasons of 1983-1985. The effects of gamma radiation, EMS, the storage periods and their interaction on some developmental stages of M1 plants were statistically significant. However, no differences were observed among M2 plants. The greatest number of variants were found among M2 plants that had originated from seeds stored since 1968, irradiated and treated with EMS
