| Outline of Final Research Achievements |
The aim of the present study was to examine use of wild grape germplasms in Japan , which are short dormant, ever bearing and short juvenile, to improve breeding efficiency of grape. Using Ryuukyuuganebu as seed parent made it possible to carry out year round crossing and to obtain many hybrids for short period. Intermediate parents of short dormant grapes were selected in this study. Meanwhile, field surveys were conducted for Okinawa Islands. Ryuukyuuganebu was distributed in Kuchinoshima Island widely, especially near the vegetable or crop fields or houses. The leaf-shapes of Ryukyuganebu in Okinawa, Amami and Tokara islands were almost similar, but the Ryukyuganebu leaves in the northern habitats trended to have 3 lobes. As breeding material, some elite lines of Ryuukyuuganebu were selected based on the berry weight, the berry juice Brix, and content of anthocyanin and resveratrol in the berry skins, from the vines native to Amami Oshima, Okinoerabu island and Okinawa island.
