Seeds of Vicia faba var minor were treated with the solutions of ethyl methane sulphonate (EMS) at 0.05%, 0.125%, and 0.25% and diethyl sulphate (DES) at 0.25%, 0.50%, and 0.75%. Germination, seedling growth, pollen fertility, time to maturity, and survival were adversely affected by both mutagens. Plant height, branching, number of leaves, pods and seeds as well as yield per plant showed varying responses to different concentrations of the mutagens. However, DES at all doses and EMS only at the highest dose had adversely affected these traits. Whereas, the lower doses of EMS had either no effect or a slight promoting effect
