The petioles are used mainly as a human food source, and \u0027Aichi-Wase-Fuki,\u0027 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 \u0027Aichi-Wase-Fuki\u0027. Subsequently, the highest yielding variant was registered in 2002 as \u0027Osaka-Nougi-Ikusei No.1.\u0027 Currently, all farmers in Osaka Prefecture cultivate this high-yield cultivar \u0027Osaka-Nougi-Ikusei No.1.\u0027.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "163145", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Iwamoto, Yuzuri"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学農学部"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00183393", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03858634", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "岩本, 嗣"}], "nameIdentifiers": [{"nameIdentifier": "163144", "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": "2019-08-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "62(2)_41-48.pdf", "filesize": [{"value": "882.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 882800.0, "url": {"label": "62(2)_41-48.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28364/files/62(2)_41-48.pdf"}, "version_id": "720a3997-97ae-4758-9867-82ea5b3a6ad8"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "ウィルスフリー", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ソマクローナル変異", "subitem_subject_scheme": "Other"}, {"subitem_subject": "頭花培養", "subitem_subject_scheme": "Other"}, {"subitem_subject": "フキ", "subitem_subject_scheme": "Other"}, {"subitem_subject": "virus-free", "subitem_subject_scheme": "Other"}, {"subitem_subject": "somaclonal variation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "flowerhead culture", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Petasites japonicus", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "バイオテクノロジーを利用した3倍体フキの育種", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "バイオテクノロジーを利用した3倍体フキの育種"}, {"subitem_title": "バイオテクノロジーを利用した3倍体フキの育種", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1597"], "permalink_uri": "http://hdl.handle.net/10191/13099", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-07-14"}, "publish_date": "2010-07-14", "publish_status": "0", "recid": "28364", "relation": {}, "relation_version_is_last": true, "title": ["バイオテクノロジーを利用した3倍体フキの育種"], "weko_shared_id": null}
