PHYLOGENETIC-RELATIONSHIPS IN THE KUMQUAT (FORTUNELLA) AS REVEALED BY ISOZYME ANALYSIS

Nine isozyme systems were investigated by polyacrylamide gel electrophoresis as a means of identifying the six species of Fortunella. By examining the characteristic isoenzymatic patterns, it was found that there was considerable variability between the different species. The relationships among the six species of Fortunella were inferred from the similarity matrix data. The results indicate that no pairs of species are identical and the degree of relationship between the species was low, suggesting that the six species of Fortunella are independent.
