Ten geontypes of sweet potato were analysed using SDS-polyacrylamide gel electrophoresis and isozymes like estarase and peroxidase. SDS-PAGE gave as many as 13-18 protein bands depending on the specificity of genotypes. Electrophoresis of esterase gave 4-6 bands in various genotypes. The isozyme profile of peroxidase was similar for all the genotypes except in band intensity. However, protein polymorphism in SDS-PAGE gave better information on genetic diversity and relationship among the genotypes of the crop.
