Abstract The polymorphism of 11 enzymes was analysed in 11 progenies from controlled crosses between pear varieties, using acrylamide and starch electrophoresis gels. Twenty-two loci were identified and segregation was scored for 20 of them. Three pairs of duplicated loci forming intergenic hybrid bands were detected, these correspond to equivalent duplicated genes in apple. A total of 49 active alleles and 1 null allele were identified. Joint segregation analysis revealed three linkage groups, which could all be related to existing groups on the apple map. The conservation of isozyme patterns, duplicated genes and linkage groups indicates a high degree of synteny between apple and pear.
