| Popis: | Fifty-four apple (Malus domestica Borkh.) cultivars were characterized electrophoretically using 6 isozyme systems. Intracultivar variation in isozyme phenotype was not observed, whereas intercultivar polymorphism was sufficient to permit reliable and unambiguous identification of nearly every cultivar. The most useful isozyme systems for distinguishing among the cultivars were 6-phosphogluconate dehydrogenase and aspartate aminotransferase. Sports could not be distinguished from the original cultivar. The genetic basic of several polymorphisms was known, enabling the comparison of the isozyme genotype observed in a hybrid with that predicted on the basis of parental genotypes. The 6-phosphogluconate dehydrogenase genotype of ‘Spartan’ indicated that ‘Yellow Newtown’ may not have been the paternal parent. |
