| Outline of Final Research Achievements |
We tried to obtain intersectional hybrids between wild species native to Japan and blueberry cultivars using reciprocal crossing. Four intersectional hybrids were obtained from the cross between colchicine-derived tetraploid shashanbo (Vaccinium bracteatum section Bracteata)as seed parent and tetraploid highbush blueberry ‘Spartan’(V. corymbosum section Cyanococcus ), and the morphological and ecological characteristics and fruit quality of these hybrids were compared with ‘Spartan’and tetraploid shashanbo. With crosses between tetraploid cultivars and diploid wild species, some intersectional hybrids were also produced. Some of these hybrids showed the interesting characteristics that accompanied by variegated leaf in part of branch or varies ploidy level (triploid or tetraploid) according to branch.
