Objective of the present investigation was the study the effectiveness of sodium azide (NaN3) on the morphological traits of the initial breeding materials of millet (Panicum miliaceum L.). The seeds were treated with different concentrations of sodium azide (0.1; 0.2; 0.3 and 0.4%). Number of morphological mutant were observed visually and recorded. According to the obtained results the stimulating effect of mutagen is clearly determined, the higher the level of the concentration of mutagen, the stronger the decrease in seed germination. In general, lower 0.1 mM concentration of sodium azide was most effective. Different concentrations of sodium azide inhibited most agronomic traits such as germination, plant height, panicle length, panicle weigth and one thousand seed weight of proso millet in the field conditions.
