To develop universal primers for phylogenetic analysis and species-specific marker for breeding program of kiwifruit, eighteens primers were designed from kiwifruit genome-specific repeat sequences. Seven species including twenty two varieties collected from native eastern Asia were examined using 18 to 22 mer kiwifruit target(KT) primers. among eighteen primers, we selected seven primers for phylogenetic relationship. The genus Actinidia was divided into two large groups; group I,A. arguta, A. melanandra, A. kolomikta, and A. marcrosperma, characterized by the non-hair in fruits and loaves or a few pubescences only in young stage, which belongs to the section Leiocarpae, and group II, A. chinensis, A. deliciosa, and A. eriantha, characterized by a lot of hairs only in young fruit stage and with a lot of hairs or fuzzes in leaves and branches, which belongs to the section Stellatae. Group II especially belongs to the series Perfectae of the section Stellatae and was divided into two subgroups; subgroup I containing A. chinensis and A. deliciosa, and subgroup II containing A. eriantha. In contrast, the two species, A. chinensis and A. deliciosa, which are known to have common parents, were divided into two independent subgroups with 80£¥ of a similarity value. On the other hand, we selected KT6F for variety specific bands, KT12E primers for 'Hayward' and 'Tomuri'. KT7F or KT12F primers were useful for analysis of inheritance pattern in kiwifruit cross-breeding. We suggest that these primers will be a powerful tool for elucidating phylogenetic relationship and selection of novelty kiwifruit in a breeding program.
