Abstract: Mung bean (Vigna radiata L.) is one of the most important grain legumes cultivated in Sri Lanka. Drought is a major abiotic stress on Mung bean in the sub-humid, dry and intermediate zones of Sri Lanka. The present reveals the response of mung bean for the drought stress at germination to seedling stages. The major beneficiaries of the intervention are the poor, especially children and women, whose diets lacked much needed protein and iron. Supplementation with improved Mung bean recipes has effectively improved low body iron stores in children and women. Both urban and rural consumers now have access to improved quality mungbean at reasonable cost. The drought is a major environmental factor that determines the growth, the productivity of crops which is estimated to be one of the most serious yield reducing stresses in crops. Surface sterilized seeds were introduced to hormone free Murashige and Skoog (MS) basal medium with different concentrations of mannitol (0%, 10%, 20%, 30%, 40% and 50%). Seedlings heights, length of the roots and number of germinated seeds were recorded after 2nd weeks of culture. Completely Randomized Design (CRD) with five replicates was used for study. Statistical analysis was performed with Duncan’s multiple range test using SAS software (version 9.1.3). Results showed that highest seed germination (100%) from Mung bean variety MI 5 and Harsha in all mannitol concentrations. Reduction of seedling height and increasing the root length was observed while increasing the mannitol concentration in both varieties.
