Twenty genotypes and 8 market samples of mungbean were evaluated on the basis of their seed storage protein (SSP) subunits profile determined by sodium dodecyl sulphate - polyacrylamide gel electrophoresis (SDS-PAGE). Subunit bands in the range of 14kD to 80kD of molecular weight (MW) were recognized in their protein samples and appeared to show four distinct regions. Region I subunit bands were invariably monomorphic. Eight bands belonging to regions II (42kD-56kD), III (25kD-35kD) and IV (14-22 kD) were polymorphic. From binary data generated from polymorphic bands over the genotypes and market samples, Jaccard’s similarity coefficients were computed using NTSYS-pc software and utilized for the dendrogram construction. The dendrogram segregated the 20 genotypes and 8 market samples into 4 clusters. Cluster I included all the genotypes (except RMG 1004) and two market samples. The remaining 6 market samples formed clusters II and III. Genotype RMG 1004 represented cluster IV with maximum divergence.
