41 test genotypes including 34 improved varieties, five local land races, one wild accession of mungbean; and one local variety of urdbean were analysed for albumin seed storage proteins by SDS-PAGE. The electrophoregrams revealed eleven polypeptide bands for albumin which has shown a great array of polymorphism in presence/absence of bands as well as the intensity/thickness of bands. The test genotypes were distributed over six clusters. The cluster analysis based on, albumin polypeptide banding patterns revealed different separate clusters for genotypes e.g., Pant M-5, RCM 15, OGG 57, OUM 7, COGG912 and ML 613 indicating their genetic divergence from rest of the genotypes. These genotypes could serve as valuable breeding material for further crop improvement.
