In this study, Alyssum virgatum, which belongs to the family of Brassicaceae. The anti-sitoxic effect of distilled water extract (Av-eks) of the surface parts of the plant on the roots of Allium cepa L. has been studied. The effects of the different periods and concentrations of Av-eks on root growth against MMS (Metilmetansulfonate), mitotic index and anaphase-telofaz chromosome aberrations have been determined. In the Allium root growth inhibition test, 10 different concentrations of Av-eks (100 gL -1 , 50 gL -1 , 25 gL -1 , 12.5 gL -1 , 6.25 gL -1 , 3.2 gL -1 , 1.6 gL -1 , 0.8 gL -1 , 0.4 gL -1 and 0.2 gL -1 ) were determined by applying EC50 value to the flour root cells. Other Av-eks concentrations except 0.8 gL -1 , 0.4 gL -1 and 0.2 gL -1 have significantly reduced the root length. The EC50, considered to be a concentration that decreases the root length to half, was found at approximately 1.6 gL-1. In the anti-toxicity test, different concentrations of Av-eks containing distillated water (negative control), MMS (positive control) and 10 ppm MMS (0,5×EC50, EC50 and 2×EC50) were used for 24, 48 and 72 hours. In the Av-ex mixture containing 10 ppm MMS, a significant increase in the mitotic index was observed due to the increase in concentration in plant extract. In chromosome aberration studies, the percentage of anomalies has been found to be reduced according to the positive control group. The thin chromosome aberration caused by the deterioration of the wire has been more detected than other anomalies. Results of Av-eks, A. It has shown that in the meristematic root cells, MMS has an anti-sitoxic and anti-genotoxic activity in the presence.
