The isozymes peroxidase, alpha-amylase and acid phosphatase from leave
s of 42 cultivars of ber (Zizyphus mauritiana, Lamk.) were studied usi
ng acrylamide gel electrophoresis. The number of cultivar specific iso
zyme phenotypes observed were 15 for peroxidase, 18 for amylase and 18
for acid phosphatase. Of the 42 cultivars 40 could be identified with
the help of the different isozyme systems.
