The present study was carried out to analyse the effect of gamma radiation on morpho-physiological parameters of seven days old M1 seedlings of Eleusine coracana (L.) Gaertn. (finger millet). The finger millet seeds were irradiated with different doses of viz., 100 Gy, 200 Gy, 300 Gy, 400 Gy, 500 Gy, 600 Gy, 700 Gy, 800 Gy, 900 Gy and 1000 Gy of gamma ray. Higher doses of gamma rays induced substantial reduction in mean performance of morphological and physiological traits. However, lower doses showed stimulatory effects on morphological and physiological traits. The results revealed a progressive decrease in chlorophyll fluorescence with increasing dose of gamma irradiation. Among all the mutagen doses used, 600 Gy gamma irradiated seeds showed enhanced mean performance of morphological and physiological traits in finger millet. Hence 600 Gy gamma rays may be employed in other crop species to improve the agro-economic traits
