Genetic polymorphism among the local community around our university was investigated by SDS-PAGE analysis of seed storage proteins in wild adzuki bean Vigna anglalis var. nipponensis. We collected seeds from five independent populations. Population I has phenotypic polymorphism in seed color, that is, black, brown, light brown, green and russet. The other four populations have only black seed color. Two polymolphic bands were detected by SDS-PAGE analysis of seed storage proteins. One was around 70kD and the other was around 60kD. Black colored seeds in population I involved six types that showed different band patterns and should be mixed lines. Seeds of each color except black in population I showed no polymorphism within the color so that they should be a pure line, respectively. But each band pattern of them were identical with one of six types of black seeds. Each of the other four population was a pure line and two populations showed one of six types of black seeds in population I. But the rest two showed different patterns. In short, two polymorphic bands and eight different band patterns were detected by SDS-PAGE analysis of seed storage proteins.
