Outline of Final Research Achievements

In this study, we analyzed phylogenetic relationships of Hydrangea macrophylla and H. serrata distributed in Japan and assessed their tolerances to the excessive solar radiation and drought for breeding of hydrangea cultivars with strong resistance to environmental stress. This study revealed the following; 1) Kubiki Mountains are one of the borders of geographical distribution between H. serrata var. serrata and var. yesoensis.; 2) Natural crossing between H. macrophylla and H. serrata occurs in Izu Peninsula; 3) H. serrata var. yesoensis as well as H. macrophylla were deeply involved in development of old hydrangea cultivars; 4) Some wild H. macrophylla plants from Hachijojima Island and Aogashima Island showed tolerance to the excessive solar radiation; There are two types of symptom on the leaves induced by the excessive solar radiation and some wild H. macrophylla plants showed tolerance to intensive radiation.
