STUDIES ON THE PHYLOGENETIC RELATIONSHIP BETWEEN ACTINIDIA CHINENSIS AND A. DELICIOSA USING CLADISTIC ANALYSIS

Xiong Zhiting (Wuhan Institute of Botany, Academia Sinica, Wuhan 430074)  
Based on morphology and chromosome number data, three identical length Wagner trees (length=28) for three evolutionary units, Actinidia chinensis (including- diploid and tetraploid) and A. deliciosa are constructed, using parsimony analysis with species A. eriantha as outgroup. One of the three trees, which coincides with the geographical distribution and cytological data of the three taxa, is considered to reflect the true phylogenetic relationship among the taxa. This tree shows that A. deliciosa had evolved from A. chinensis rderived from the diploid of the same species. Although A. deliciosa has been revised as a species, it may be one of the members of A. chinensis species complex.
