Over the last few years, we have been classifying various G. max and G. soja lines based on their electrophoretic zymogram patterns. In the 1982 Soybean Genetics Newsletter (Gorman et al., 1982), we published a table compiling electrophoretic profiles for most of the named soybean cultivars in the early maturity groups (000-IV). Listed on the table below is a similar compilation of electroohoretic profiles (zymogram types for 12 enzyme systems) for 60 G. max Pis (10 originating from Northeast China, 10 from Central China, 20 from Korea, and 20 from Japan) as well as 90 named cultivars in the late maturity groups (V-VIII).
