The studies of induced mutation in Linum usitatissimum L. were performed by exposing the fully matured and
healthy dry seeds to gamma rays at 10 and 15 Krad (Kr), Xrays at 10 and 15 Kr, hydroxylamine (HA) at 0.1% and
0.2%, and 5amino acridine (AA) at 0.1% and 0.2% doses. The observations were made for seed germination
percentage, survival percentage, and growth characters such as shoot length, root length, and dry weight. Seeds treated with low dose of mutagens showed negligible effect while that with the high dose exhibited significant effects on studied parameters as compared to control. Data obtained in this study were statistically significant at 5% level. The results conclude that treatments of gamma rays and X-rays were less effective as compared to those of HA and AA treatments.
