摘要：

The present study was carried out to analyse the effects of gamma radiations on physio-morphological traits of seven days old M(1)seedlings of Eleusine coracana (L.) Gaertn. (finger millet). The finger millet seeds were irradiated with different doses of gamma rays viz., 100 Gy, 200 Gy, 300 Gy, 400 Gy, 500 Gy, 600 Gy, 700 Gy, 800 Gy, 900 Gy and 1000 Gy. Lower and higher doses of gamma rays induced a substantial increase and decrease in the mean values of physiological and morphological traits respectively. The results revealed a progressive decrease in chlorophyll fluorescence with an increasing dose of gamma rays. Among all the mutagen doses employed, 600 Gy gamma-irradiated seeds showed maximum mean values of physiological and morphological traits in finger millet. Hence, 600 Gy gamma rays may be employed in other related crop species to improve the agro-economic traits.
