Abstract: In 1981—1986, the effects of photo-period and temperature on the development of wild soybean (Glycine soja) from various locations, with latitude 24—53˚N, longitude 97—143˚E and altitude 0–2650m, were studied. According to the analytical data of 343 germ-plasm lines (China 292,Japan 32, South Korea 14, USSR 5), seven ecotypes and their geographical regions and thirteen sub-regions were divided. They are: 1. the northern ultraearly-maturing region. 2. the northern early-maturing region. 3. the western plateau early-maturing region. 4. the central medium-maturing region. 5. the central-southern medium-late-maturing region. 6. the south-western late-maturing region. 7. the south-eastern ultra-late-maturing region.
