Summary Peroxidase isozymes were studied in the Triticum aestivum L. kernel and in nullisomic-tetrasomic and ditelocentric combinations of ‘Chinese Spring’ wheat. Analyses were carried out on different parts of dry kernels (embryo plus scutellum and endosperm) using polyacrylamide and starch gel electrophoresis, different electrophoretic buffer systems and various staining methods. The peroxidase isozymes showed a low substrate-specificity and a high tissue-specificity. The embryo plus scutellum and the endosperm always presented different peroxidase patterns. Endosperm peroxidases were associated with chromosome arms 7DS, 4BL and 7AS; whereas the embryo plus scutellum isozymes were related to chromosome arms 3AL, 3BL and 3DS. The different results obtained using various electrophoretic techniques are due to the buffer system used. All staining procedures employed revealed the same peroxidase isozymes.
