Abstract Mutagenic effect of Ethylene Glycol on interphase chromosome volume (ICV) and structural chromosomal aberrations were studied using five different doses of mutagen along with a control. The ICV was found to be mutagen sensitive in somatic cells of wheat. It was found to increase with increasing the doses of mutagen in all the five varieties of wheat. The chemical mutagen, Ethylene Glycol was also found to induce high frequency of chromosomal changes like chromatid bridges, chromosome fragments, laggards etc. Their frequencies were also found to increase with increase of the doses. Regarding treatment durations the materials treated for 24 hours showed significantly higher values compared to that of 12 and 6 hours.
