It was first reported in Japan in the Taisho era. With the increase of land used for domestic wheat production, outbreaks of this disease occurred in the 1990s in Japanese wheat production areas. The breakdown of resistance also occurred, and the disease has become an obstacle to increased wheat production in Japan. Countermeasures to this disease have been restricted to changes in cultural practices and the use of resistant cultivars. On the other hand, because of the lack of an experimental inoculation system, the mechanism of cultural practices to control this disease were not clarified, and the relationship between WYMV strains and the resistance of wheat cultivars to the virus were not clear. This study was conducted to contribute to the development of resistant cultivars and practical cultural practices to control wheat yellow mosaic disease. For this purpose, the ecology of this disease was clarified from the aspects of the effect of temperature on the disease. The favorable temperature for the virus to propagate in the wheat plants is about 10℃, while 5-10℃ is favorable to disease progression. Masking of the symptoms occurred when the temperature was above 10℃, and then the wheat plant recovered from the disease. The favorable temperature for the infection of P. graminis ranges from 13℃ to 15℃. Based on this knowledge, we have clarified why late sowing is an effective disease control measure for this disease. An experimental inoculation system that consistently had high inoculation efficiency was also developed.\n","subitem_description_type":"Abstract"},{"subitem_description":"コムギ縞萎縮病は, 土壌生息性の原生動物 Polymyxa graminis により媒介される土壌伝染性のウイルス病害である。大正年間に我が国で最初に報告され, 国内の主要なコムギ産地に発生し被害を及ぼしてきた。抵抗性品種の罹病化, 突発的な大発生が各地で認められ解決が求められた。本病の防除の主体は, 耕種的防除技術と抵抗性品種の利用に限られる。一方で, 接種試験系がないために, 耕種的防除法の機作や, 抵抗性品種と WYMV の病原性系統の関係も明らかではなかった。本研究は, コムギ縞萎縮病の耕種的防除技術の開発並びに抵抗性品種の開発に資するために行った。そのために, 本病の発生生態の詳細を, 温度環境の影響を中心に明らかにし, ウイルスの増殖には約10 ℃が適すること, 病勢は5 ～ 10 ℃で進展し, 10 ℃以上ではマスキングにより停滞し病徴が回復することを明らかにした。さらに, P. graminis の活動適温が約13 ～ 15 ℃であることも明らかにした。これらの情報に基づいて晩播の防除機作を明らかにした。さらに, コムギ縞萎縮病の接種効率の高い接種実験系を確立した。\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001184","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人 農業・生物系特定産業技術研究機構 東北農業研究センター"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00001184","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-3379","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大藤, 泰雄"},{"creatorName":"オオトウ, ヤスオ","creatorNameLang":"ja-Kana"},{"creatorName":"OHTO, Yasuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1583","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50355286","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50355286"},{"nameIdentifier":"oto","nameIdentifierScheme":"researchmap","nameIdentifierURI":"http://researchmap.jp/oto"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-07"}],"displaytype":"detail","filename":"tarc_report_No104p17-74p.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tarc_report_No104p17-74p.pdf ","url":"https://repository.naro.go.jp/record/1217/files/tarc_report_No104p17-74p.pdf"},"version_id":"a0373d6f-e6c7-44b5-b617-8fe225bbe2d9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"コムギ縞萎縮病","subitem_subject_scheme":"Other"},{"subitem_subject":"WYMV","subitem_subject_scheme":"Other"},{"subitem_subject":"Polymyxa graminis","subitem_subject_scheme":"Other"},{"subitem_subject":"発生生態","subitem_subject_scheme":"Other"},{"subitem_subject":"耕種的防除法","subitem_subject_scheme":"Other"},{"subitem_subject":"晩播","subitem_subject_scheme":"Other"},{"subitem_subject":"Wheat yellow mosaic disease","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"WYMV","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Polymyxa graminis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ecology","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Cultural practices","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Late sowing","subitem_subject_language":"en","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":"コムギ縞萎縮病の発生生態に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"コムギ縞萎縮病の発生生態に関する研究"},{"subitem_title":"Study on the Ecology of Wheat Yellow Mosaic Disease","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"12","path":["180"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-22"},"publish_date":"2019-03-22","publish_status":"0","recid":"1217","relation_version_is_last":true,"title":["コムギ縞萎縮病の発生生態に関する研究"],"weko_creator_id":"12","weko_shared_id":12},"updated":"2023-05-15T15:47:44.716309+00:00"}
