Abstract: RAPD genetic analysis were conducted on 32 Northeast China soybean genotypes.A cluster analysis was performed by using the PSBAPC2 computer program, based on the furthest neighbor, and a phenograme was constructed.The results indicated that cultivators of different districts were grouped together separately, conforming to the geographical distribution.The wild.G.soja) and semiwild.(G.gracillis) materials were grouped together, but the two were separated strikingly from the cultivators.G.max).Based on this analysis, G.gracillis and G.soja should and were distincted from G.max , Perhaps be considered as one species.
