A green seed coat colour mutant induced by 0.06% MMS and its parental strain were studied during present investigation. The mutant differed from the control not only in seed coat colour but also in some cytomorphological, palynological and biochemical characters. The mutant was superior to the control in herbage, seed and crude oil yield. The induced mutant seems to be originated due to gene mutation.
