This study concerns the induct ion of genetic variabilities in some morphological and yield component characters infiibibcnn(Vicia faba L.)by gamma rays. Five varieties of faba bean were used in this study with four different doses of gamma rays.5,10.20 and 30 K rad. Nine characters were studied in both Ml and M2 plants. Data revealed that the increase of gamma rays doses has a significant negative effect on the Ml seed germination in all the treated cultivars. However in M2 seed there is no effect. Concerning the shoot length, data showed that gamma rays had a significant positive effect at the mosi used doses for M1 plants, while in M2 plants the effect was negative. For (he other characters, most results of Ml plants showed that 5 K. rad dose had a positive effect as compared to the control. While at the other doses the effect ranged between negative and no effects
