Forty five isolates were classified into 15 races through the inoculation test by 10 differential cultivars used in the previous reports. Out of 15 races, 13 were new and most of them were more pathogenic than those of the past, which showed the progress of pathogenicity to the differentials, e.g. some isolates were found to be pathogenic to Tennessee Winter and Atlas 46 which had been highly resistant to the pathogen distributed in Hokuriku and Tohoku districts. With reference to the change of pathogenicity, it was suggested that J-6 and/or J-10 should be added to J-4a which was already used for the screening of resistance of genetic resources or breeding process. To obtain more appropriate composition of the differentials, reaction patterns to the pathogen and genotypes for the resistance in the 10 differentials and 16 internationally used ones were analyzed by the principal component analysis. A total of 26 differentials were classified into 6 groups. Since 3 out of 6 groups did not include 10 differentials, Osiris, Jet, Nigrinudum and C.I.4368 were recommended as newly added differential cultivars. Furthermore, evaluating method for the degree of susceptibility was discussed.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"163289","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Takeuchi, Kazunari"}]},{"nameIdentifiers":[{"nameIdentifier":"163290","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Fukuyama, Toshinori"}]}]},"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":"竹内, 一成"}],"nameIdentifiers":[{"nameIdentifier":"163287","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福山, 利範"}],"nameIdentifiers":[{"nameIdentifier":"163288","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","filename":"61(2)_149-157.pdf","filesize":[{"value":"774.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"61(2)_149-157.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28384/files/61(2)_149-157.pdf"},"version_id":"a5b66f5c-f83b-4982-bc35-549789ea4d1e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"オオムギ","subitem_subject_scheme":"Other"},{"subitem_subject":"雲形病","subitem_subject_scheme":"Other"},{"subitem_subject":"判別品種","subitem_subject_scheme":"Other"},{"subitem_subject":"Rhynchosporium secalis","subitem_subject_scheme":"Other"},{"subitem_subject":"レース変遷","subitem_subject_scheme":"Other"},{"subitem_subject":"barley","subitem_subject_scheme":"Other"},{"subitem_subject":"differential cultivar","subitem_subject_scheme":"Other"},{"subitem_subject":"racial change","subitem_subject_scheme":"Other"},{"subitem_subject":"Rhynchosporium secalis","subitem_subject_scheme":"Other"},{"subitem_subject":"scald","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":"北陸・東北地方におけるオオムギ雲形病菌のレース分布および変遷とその同定に関する提案","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"北陸・東北地方におけるオオムギ雲形病菌のレース分布および変遷とその同定に関する提案"},{"subitem_title":"北陸・東北地方におけるオオムギ雲形病菌のレース分布および変遷とその同定に関する提案","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1599"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-07-02"},"publish_date":"2010-07-02","publish_status":"0","recid":"28384","relation_version_is_last":true,"title":["北陸・東北地方におけるオオムギ雲形病菌のレース分布および変遷とその同定に関する提案"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:26.835423+00:00"}
