Abstract:

Isozymes of peroxidase of 10 species in Juglans L. were analyzed by using poly-

crylamide gel electrophoresis, and, as a result, 16 different patterns of isozymes were observed.

Polymophism of isozymes patterns appears within species and more significant differences in pat-

tern between species have been found. “Zymogram distance” was measured for each species

pair and section pair. The ten species may be divided into 4 groups according to their “zymo-

gram distance” and specific bands, which accords with the classical taxonomy of Juglans L..

Evolutionary relationship among species and rate of evolution for Juglans L. are discussed.

Key words: Juglans, Lsozyme
