Monogenic lines for blast resistance have been newly developed at the International Rice Research Institute (IRRI) as international differential varieties and differential blast isolates from the Philippines were selected. Using a differential system based on the gene-for-gene theory, blast resistance genes were estimated in the IRRI-bred elite rice varieties. At least seven kinds of resistance genes --Pi20(t), Pita, Pik* (one of the Pik allele genes except Pik-s), Pik-s, Pib, Piz-t, and Pii or Pi3 -- were estimated in 42 rice varieties on the basis of reaction patterns to 14 standard blast isolates. The reaction patterns of the IRRI varieties were compared with those of the blast monogenic lines. To confirm this gene estimation, genetic analysis was done using segregating populations derived from crosses between the IRRI varieties and a susceptible Indica-type variety, CO 39. The BC1F2 populations (with CO 39 as recurrent parent) were segregated for reaction to the specific standard isolates. Furthermore, the estimated genes were confirmed by allelism test against the blast resistance monogenic lines. As a result of the segregation analysis of 10 of 42 IRRI-bred varieties, seven genes -- Pi20(t), Pita, Pik*, Pia, Pib, Piks -- and Piz-t, were identified. Genes Pia, Pib, Pik-s, and Piz-t were not estimated by reaction patterns to the blast isolates but identified by genetic analysis in some varieties. The effectiveness of the differential system, which is based on conventional methods and which does not require advanced facilities, is discussed as a fundamental tool to provide essential information to develop breeding programs for blast resistance.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available"}],"filename":"jircas_working_report63-_69-86.pdf","filesize":[{"value":"763KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"jircas_working_report63-_69-86","objectType":"fulltext","url":"https://jircas.repo.nii.ac.jp/record/2000250/files/jircas_working_report63-_69-86.pdf"},"version_id":"c29b4d4b-2ee9-4aa6-8da9-f5a6a57e475e"}]},"item_30002_identifier_registration17":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34556/0002000250","subitem_identifier_reg_type":"JaLC"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_30002_publisher10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan International Research Center for Agricultural Sciences","subitem_publisher_language":"en"}]},"item_30002_relation18":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"en","subitem_relation_name_text":"Development and Characterization of Blast Resistance Using Differential Varieties in Rice"}],"subitem_relation_type":"isPartOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.34556/0002000242","subitem_relation_type_select":"DOI"}}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"book part","resourceuri":"http://purl.org/coar/resource_type/c_3248"}]},"item_30002_source_identifier22":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"1341-710X","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"AA11159468","subitem_source_identifier_type":"NCID"}]},"item_30002_subject8":{"attribute_name":"主題","attribute_value_mlt":[{"subitem_subject":"rice (Oryza sativa L.)","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"blast (Pyricularia oryzae Cavara )","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"differential system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"genetic analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"resistance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"IRRI variety","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30002_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Identification of blast resistance genes in IRRI-bred rice varieties by segregation analysis based on a differential system","subitem_title_language":"en"}]},"item_30002_version_type15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"Identification of blast resistance genes in IRRI-bred rice varieties by segregation analysis based on a differential system","item_type_id":"40039","owner":"74","path":["1715565337507"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-05-16"},"publish_date":"2024-05-16","publish_status":"0","recid":"2000250","relation_version_is_last":true,"title":["Identification of blast resistance genes in IRRI-bred rice varieties by segregation analysis based on a differential system"],"weko_creator_id":"74","weko_shared_id":-1},"updated":"2024-05-31T04:23:38.899450+00:00"}
