In order to solve the lodging problem in millet production, Jingu 21 was induced by EMS, and a highquality dwarf mutant millet variety was selected. The photosynthetic characteristics, agronomic characters, nutrient element content, yield and millet quality of mutant millet were analyzed and compared. The results showed that the net photosynthetic rate per unit area of dwarf mutant millet induced by EMS was lower, but the total leaf area was larger. Although the yield decreased, the quality of millet was better. The decrease of plant height and the increase of stem diameter are conducive to solving the lodging problem in millet production.
