But almost all seedlings were albino and have never grown at anthesis.\nIn 1996, we succeeded to obtain the green seedlings by three way crossings among R.japonicum and evergreen azaleas. We reported that high frequency of albino plant appearance was caused by incompatibility between plastome from evergreen species and nuclear genome from R.japonicum, and that green plants appeared only when their plastomes were originated from R.japonicum. Therefore, to succeed the frequency of green plant obtainment, R.japonicum should be used as seed parents in such crosses. But such crossings are unsuccessful because of failure to set capsules. IN this study, we obtained a green seedling from the single crossing between R. kiusianum x R. japonicum. This seedling was triploid and have plastome from evergreen species. In the previous reports, we investigated that the appearance of albino seedlings seem to originated in the incompatibility between ptDNA and nuclear DNA. From these findings, however, it seems that the triploid seedlings that have nuclear genome originated from R. kiusianum (2x) and originated from R. japonicum (x) show green leaves and not show the incompatibility."}]}],"researcher":[{"@id":"https://cir.nii.ac.jp/crid/1030003658330955521","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"20182024"},{"@type":"NRID","@value":"1000020182024"},{"@type":"NRID","@value":"9000001989082"},{"@type":"NRID","@value":"9000412188250"},{"@type":"NRID","@value":"9000023608194"},{"@type":"NRID","@value":"9000312729103"},{"@type":"NRID","@value":"9000405731358"},{"@type":"NRID","@value":"9000003137977"},{"@type":"NRID","@value":"9000329020607"},{"@type":"NRID","@value":"9000258082197"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0118239"}],"foaf:name":[{"@language":"ja","@value":"宮島 郁夫"},{"@language":"en","@value":"MIYAJIMA Ikuo"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"九州大学"},{"@language":"en","@value":"Kyushu University, Fac.of Agriculture, Assistant Professor"}],"role":"principal_investigator"},{"@id":"https://cir.nii.ac.jp/crid/1420001326233579776","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"60253514"},{"@type":"NRID","@value":"1000060253514"},{"@type":"ORCID","@value":"0000-0003-3005-5451"},{"@type":"NRID","@value":"9000411497988"},{"@type":"NRID","@value":"9000002227113"},{"@type":"NRID","@value":"9000413871751"},{"@type":"NRID","@value":"9000342446483"},{"@type":"NRID","@value":"9000413871746"},{"@type":"NRID","@value":"9000414834628"},{"@type":"NRID","@value":"9000260190009"},{"@type":"NRID","@value":"9000408574080"},{"@type":"NRID","@value":"9000408888152"},{"@type":"NRID","@value":"9000006855114"},{"@type":"NRID","@value":"9000006339681"},{"@type":"NRID","@value":"9000413871758"},{"@type":"NRID","@value":"9000408574084"},{"@type":"NRID","@value":"9000005831473"},{"@type":"NRID","@value":"9000260189978"},{"@type":"NRID","@value":"9000402454485"},{"@type":"NRID","@value":"9000415125500"},{"@type":"NRID","@value":"9000005831289"},{"@type":"NRID","@value":"9000406046692"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/hortsci4564"}],"foaf:name":[{"@language":"ja","@value":"尾崎 行生"},{"@language":"en","@value":"OZAKI Yukio"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"九州大学"},{"@language":"en","@value":"Kyushu University, Fac.of Agriculture, Assistant Professor"}],"role":"co_investigator_buntan"}],"since":"1998","until":"1999","institution":[{"institutionIdentifier":[{"@type":"NII","@value":"0017102"}],"notation":[{"@language":"ja","@value":"九州大学"},{"@language":"en","@value":"KYUSHU UNIVERSITY"}]}],"fundingProgram":[{"jpcoar:funderName":[{"@language":"ja","@value":"科学研究費助成事業"},{"@language":"en","@value":"Grants-in-Aid for Scientific Research"}]}],"url":[{"@id":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-10660031/","notation":[{"@value":"KAKEN"}]}],"createdAt":"1998-03-31","modifiedAt":"2025-11-20","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=%E5%B8%B8%E7%B7%91%E6%80%A7%E3%83%84%E3%83%84%E3%82%B8","dc:title":"常緑性ツツジ"},{"@id":"https://cir.nii.ac.jp/all?q=%E9%BB%84%E8%89%B2%E8%8A%B1","dc:title":"黄色花"},{"@id":"https://cir.nii.ac.jp/all?q=%E8%82%B2%E7%A8%AE","dc:title":"育種"},{"@id":"https://cir.nii.ac.jp/all?q=%E3%82%A2%E3%83%AB%E3%83%93%E3%83%8E","dc:title":"アルビノ"},{"@id":"https://cir.nii.ac.jp/all?q=%E5%80%8D%E6%95%B0%E6%80%A7","dc:title":"倍数性"},{"@id":"https://cir.nii.ac.jp/all?q=%E9%BB%84%E8%8A%B1%E3%83%84%E3%83%84%E3%82%B8","dc:title":"黄花ツツジ"},{"@id":"https://cir.nii.ac.jp/all?q=%E3%83%97%E3%83%A9%E3%82%B9%E3%83%81%E3%83%89DNA","dc:title":"プラスチドDNA"},{"@id":"https://cir.nii.ac.jp/all?q=RFLP","dc:title":"RFLP"},{"@id":"https://cir.nii.ac.jp/all?q=%E4%B8%80%E5%81%B4%E4%BA%A4%E9%9B%91%E4%B8%8D%E8%A6%AA%E5%92%8C%E6%80%A7","dc:title":"一側交雑不親和性"},{"@id":"https://cir.nii.ac.jp/all?q=%E8%8A%B1%E7%B2%89%E7%AE%A1","dc:title":"花粉管"},{"@id":"https://cir.nii.ac.jp/all?q=Evergreen%20azalea","dc:title":"Evergreen azalea"},{"@id":"https://cir.nii.ac.jp/all?q=Yellow%20flower","dc:title":"Yellow flower"},{"@id":"https://cir.nii.ac.jp/all?q=Breeding","dc:title":"Breeding"},{"@id":"https://cir.nii.ac.jp/all?q=Albino","dc:title":"Albino"},{"@id":"https://cir.nii.ac.jp/all?q=Ploidy","dc:title":"Ploidy"}],"dataSourceIdentifier":[{"@type":"KAKEN","@value":"10660031"}],"grant":{"grantIdentifier":[{"@type":"NII","@value":"54"}],"jpcoar:fundingStream":[{"@language":"ja","@value":"基盤研究(C)"},{"@language":"en","@value":"Grant-in-Aid for Scientific Research (C)"}]},"allocationClassification":[{"notation":[{"@language":"ja","@value":"補助金"},{"@language":"en","@value":"Single-year Grants"}]}],"projectStatus":"project_closed","allocationAmount":{"totalCost":{"amount":"3600000","currency":"JPY"},"breakdownCost":[{"notation":[{"@language":"ja","@value":"直接経費"},{"@language":"en","@value":"Direct Cost"}],"amount":"3600000","currency":"JPY"}]}}
