title: The chromosomal location of peroxidase isozymes of the wheat kernel.
abstract: The analysis of the individual parts of the Triticum aestivum L. kernel yields a total of 11 peroxidase isozymes: m, n, a, c, d1, d, d2, e, f, g and h (in order from faster to slower migration). Isozymes a, c and d are found in the endosperm (Ed) and seed coats (C), while m, n, d1, d2, e, f, g and h are peculiar to the embryo and scutellum (E + S). The use of the nullitetrasomic and ditellosomic series of 'Chinese Spring' wheat allows peroxidase isozymes to be associated with specific chromosome arms. Isozymes a, c and d (Ed) are associated with chromosome arms 7D(S), 4B(L) and 7A(S); whereas isozymes m, d2, e and f are associated with chromosome arms 3D(S), 3B(L), 3D(L) and 3D(L), respecitvely. Thus, the E + S isozymes are associated with homoeology group 3 and the Ed isozymes with homoeology groups 7 (a and d isozymes) or 4 (c isozymes).
