Abstract: Foxtail millet (Setaria italica B. ) male- sterile line 927A and it. s near isogonics fert ile line 927Cw ere used as ex perimental materials. The deference betw een content of endohormone in their plant s was analyzed.Results show ed that Sterility was related to low content of indole acet ic acid (IAA) in 927A plant. Thefert ility of 927A plant s t reated by indole acetic acid (IAA) was improved,Selfed seed sit t ing percentage was increased.Indole acetic acid (IAA) could maintain the sterility of 927A.

Key words: Millet, Nuclear inherited sterility, Indole acet ic acid (IAA), Chemical maintenance of sterility
