Abstract：A dwarf mutant of winged bean〔Psophocarpus tetragonolobus（L.）DC.〕radiated by 60Coγ was screened from mutant generations. The mutant was studied on its major agronomic characters, photosynthetic characteristics and nutritional quality in this paper. The mutant obviously differed from‘Zhongyi No.1’（contrast）in plant height, stem diameter, etc. Compared with the contrast, variation in mutant plant height（48 cm）was very significantly different, with falling range of 89.9 %. Chlorophyll content and net photosynthetic rate（Pn）increased 6.7 % and 13.6 %, respectively. The latter was significantly different from the contrast. Contents of some nutritional components, including fattiness, VC and dissoluble sugar, were very significantly different, but the contents of protein and faecula were almost the same.
