Summary
A rapid method for differentiating between Citrus clones as well as between zygotic and nucellar plants has been developed. It is based on determination of peroxidase isoenzyme patterns in small root samples. Ten to 14 bands could be distinguished, in contrast to the small number of bands present in leaves. Tetraploid seedlings gave uniform patterns closely resembling the diploid, while triploids showed segregation in isozyme pattern.
