Peroxidase isozyme patterns in 23 materials of Ipomoea genus (including 10 diploid wild species,2 tetraploid wild species,7 hexaploid wild strains and 4 hexaploid cultivars ) were investigated via slab polyacrylamide gel electrophoresis technique.The primary results showed that zymogram variation could be found obviously among different species especially in diploid and tetraploid wild species rather than in different hexaploid wild strains or in different hexaploid cultivars.However, 4 dominant bands, pb2, pb3, pc1 and pc2, were presented in I,trifida (6x), I. trifida (2x), I. littoralis(4x) and I. batatas L. (sweet potato) simultaneously which could be considered as the marked bands of B group spcies in Ipomoea batatas section
