[Method] Foxtail millet cultivar Changnong35 which is widely used in agricultural production, was treated with 0.8% and 1.0% EMS; and then seven traits of mutants were investigated analyzed, to classify the mutants into different groups. [Result] 282 mutants in the M1 generation related to plant type were obtained, of which, 100 mutant plants treated with 0.8% EMS can be divided into 10 groups; 182 mutant plants obtained by using 1.0% EMS can be divided into 17 groups. The analysis results of the mature plant type traits of the M1 Generation showed that, plant height, diameter of stem under spike, diameter of the first internode under spike and internode number of the mutants treated with 1.0% EMS were significantly different from those of control, while those of mutants treated with 0.8% EMS did not show significant difference from those of control. [Conclusion] The inducing with 1.0% EMS was more conducive to obtain a large number and different types of mutants from Changnong35.展开更多
