Abstract :
Seed storage proteins are considered as biochemical markers, which are less affected by the environment and have high repeatability, and have become a powerful tool in studying genetic variation within and among genotypes in crop plants and also distinguishing cultivars of a particular crop species. In this study, 17 genotypes of soybean were studied using SDS-PAGE. The results showed that genetic diversity average for all detected loci including total proteins and low molecular weight (LMW-GS) was equal to 0.48 and for proteins with high molecular weight (HMW-GS) was 0.42. Additionally, Shannon average index were 0.4096, 0.41 and 0.60 respectively with regard to three storage proteins examined. While the cluster analysis produced from total proteins divided genotypes into four groups, proteins with low molecular weight (LMW-GS) and high molecular weight(HMW-GS) divided them into three groups. This polymorphism could be used in any biochemical marker based breeding programs to facilitateselection.
