The petioles are used mainly as a human food source, and ‘Aichi-Wase-Fuki,’ the most widely grown cultivar, is triploid and propagated vegetatively. Growth problems have been caused by three types of wide-spreading virus, arabis mosaic virus, butterbur mosaic virus and cucumber mosaic virus in Osaka Prefecture. To establish efficient mass propagation of virus-free plants, adventitious buds were regenerated directly from immature flowerheads of Japanese butterbur. Osaka native lines of Japanese butterbur were collected from the production field, and the highest yielding clonal line was selected by comparison cultivation using virus-free plants regenerated from the collections. To induce somaclonal variation related to plant yield, adventitious buds were regenerated directly from immature flowerheads of Japanese butterbur. The total yield of the highest-yielding variant induced by somaclonal variation was 20.89 t/ha, which was 129.8% that of ‘Aichi-Wase-Fuki’. Subsequently, the highest yielding variant was registered in 2002 as ‘Osaka-Nougi-Ikusei No.1.’ Currently, all farmers in Osaka Prefecture cultivate this high-yield cultivar ‘Osaka-Nougi-Ikusei No.1.’", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本植物細胞分子生物学会", "subitem_publisher_language": "ja"}]}, "item_5_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.5511/plantbiotechnology.26.189", "subitem_relation_type_select": "DOI"}}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA11250821", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1342-4580", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Iwamoto, Yuzuri", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "37567", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ZL_26(2)_189-196.pdf", "filesize": [{"value": "2.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2500000.0, "url": {"label": "ZL_26(2)_189-196.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2515/files/ZL_26(2)_189-196.pdf"}, "version_id": "5c965dab-e191-4161-a302-f0b1957abc04"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Flowehed culture", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Petasites japonicus", "subitem_subject_scheme": "Other"}, {"subitem_subject": "somaclonal variation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "virus-free", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Breeding of Japanese butterbur (Petasites japonicus) by using flowerhead culture", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Breeding of Japanese butterbur (Petasites japonicus) by using flowerhead culture", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "487"], "permalink_uri": "http://hdl.handle.net/10191/17587", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2012-04-04"}, "publish_date": "2012-04-04", "publish_status": "0", "recid": "2515", "relation": {}, "relation_version_is_last": true, "title": ["Breeding of Japanese butterbur (Petasites japonicus) by using flowerhead culture"], "weko_shared_id": -1}
