Evaluation of genetic diversity in soybean genotypes (Glycine max) based on SDS-PAGE.

The genetic variation of seed protein was assayed by SDS-PAGE for 19 genotypes of soybean (Glycine max). The result of factor analysis for SDS-PAGE 5 independent factors for characters to explain %78.018 variation of all data. A similarity dendrogram was constructed using complete clustering analysis for molecular data varieties were classified into 7 groups. On the basis of SDS-PAGE, 20 reproducible bands were used for analysis and genetic diversity was estimated based on the number of different protein peptides. Ten major bands were recorded out of total 20 bands detected, while 60% of total were polymorphic. The SDS-PAGE which was used in this study showed good genetic diversity between genotypes.
