title: Inheritance and linkage relationships of peroxidase isoenzymes in apple.
abstract: Six anodal and two cathodal zones of peroxidase activity were observed in apple and designated PRX-I to PRX-VIII from the most anodal to the most cathodal on the basis of migrational distance. PRX phenotypes were found to be coded by at least eight genes (PRX-1-8); analyses of four (PRX-2, PRX-3, PRX-4 and PRX-7) revealed 15 alleles including three null alleles. PRX-2 and PRX-3 were closely linked, and PRX-1 appeared to be in the same linkage group. In addition, PRX-4 and PRX-5 were linked.
