Lack of genetic and cytogenetic effects in mice fed on irradiated wheat.

Experiments were conducted to test the mutagenicity of wheat irradiated with 20 and 200 krad gamma-rays by feeding male and female mice for various periods starting from weaning time. The results obtained from dominant lethal tests, specific locus mutation test, studies on chromosome rearrangements in males and gonadal cell survival studies indicated no positive evidence for genetic and cytogenetic effects.
