Title: Isoenzyme Polymorphism in Apricot Cultivars
Authors: D. Milatovic, D. Nikolic, D. Šurovic, J. Milivojevic
Abstract:
Eighteen enzyme systems were studied in 50 apricot (Prunus armeniaca L.) cultivars of diverse geographical
origin using polyacrylamide gel electrophoresis.
Thirteen systems were polymorphic at 20 loci.
This polymorphism
allowed unique identification of 31 cultivars, while the remaining 19 cultivars were divided into six groups.
The
most useful enzymes in apricot cultivar identification were esterase, amylase, alanine (or leucine) aminopeptidase
and glutamate dehydrogenase.
Isoenzyme variability was highest in the cultivar groups originating from Central
Asia and from the former USSR countries.
European and North American cultivars showed a medium level of
variability, while polymorphism was lowest in genotypes from Serbia.
