Abstract

Abstract:

The acidic peroxidase isozymes in petals of 106 Citrus and Fortunella species and

cultivars were studied using polyacrylamide gel electrophoresis. The results (Fig. 1; Tables 1

and 2) suggest that these isozymes be of the monomeric nature coded by a single locus. Five

alleles were identified and designated as A, B, C, D and F respectively. No genetic difference

in peroxidase isozymes was detected among the mandarins orignated from China, Japan and

Indian. Man Ju may be a hybrid between Ponkan and Ougan. Ponkan may have not been in-

volved in the origin of Jiao Gan. Zheng Jiang Jin Ju should be an infraspecific hybrid of C.

reticulata. C. sinensis has a close relationship with some Chinese mandarins. Changshou

Kumquat and Calamondin are shown to be intergeneric hybrids between Citrus and

Fortunella.
