Abstract

                                Dry seeds of Vigna marina Merr. and Siratro were exposed to different doses of gamma rays to study their effect on various plant characters like germination, seedling height, leaf number, number of branches and plant height. The results revealed that there was more reduction at higher doses compared to lower doses for all the characters for both the crops. The results obtained in the present study clearly indicate that different doses of gamma rays can be effectively utilized to create variability for various quantitative traits in both the crops.

Key words : Gamma rays, Vigna marina Merr., Siratro
