英文摘要	Dwarf mutants identified from various crop species have been extensively used as valuable resources for breeding lodging resistant elite cultivars. The response of dwarf lines to gibberellic acid 3 (GA(3)) is important for dwarf mutant identification and classification. Forty-eight foxtail millet [Setaria italica (L.) P. Beauv.] dwarf lines collected from different breeding programs in China were tested for their response to GA(3) at the seedling stage. Forty-six of the samples were identified as being sensitive to GA(3) treatments and two lines, 84133chunhe and Xianai, were identified as insensitive. For most sensitive lines, seedling, leaf, mesocotyl, and coleoptile showed positive reaction to GA(3), increasing their length at most of the concentrations. Root responses to GA(3) were diverse but mostly negative. The mesocoty1 is the most sensitive to GA(3) solutions with concentrations between 30 and 50 mg kg(-1) and is suggested as the best test for gibberellic acid (GA) sensitivity in foxtail millet. The results in this paper indicate that multiple dwarfing genes might exist in foxtail millet and that these dwarf lines will be useful for further studies.
