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

Nine isozyme systems were investigated by polyacrylamide gel electroph oresis as a means of identifying the six species of Fortunella. By exa mining the characteristic isoenzymatic patterns, it was found that the re was considerable variability between the different species. The rel ationships 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 l ow, suggesting that the six species of Fortunella are independent.
