Japan International Research Center for Agricultural Sciences (JIRCAS) has been conducting the research project, titled “Blast Research Network for Stable Rice Production,” to solve this problem since 2006. Under the research network, an international differential variety set (DVs: monogenic lines) for 23 blast resistance genes; Pish, Pib, Pit, Pia, Pii, Pi3, Pi5(t), Pik-s, Pik-m, Pi1, Pik-h, Pik, Pik-p, Pi7(t), Pi9(t), Piz, Piz-5, Piz-t, Pita-2, Pita, Pi12(t), Pi19(t), and Pi20(t), and the methods of evaluation for reaction patterns of DVs against blast isolates and designation of blast races, are commonly used among participating nations (Korea, China, Vietnam, Philippines, Indonesia, Lao PDR, Cambodia, Bangladesh, Kenya, and Japan), international agricultural institutes (IRRI and AfricaRice), and university (Yunnan Agricultural U., China). The genetic variations of blast races and of resistance in rice cultivars have been clarified in each country and at the global level. These genetic variations of blast races and of resistance in rice cultivars differ dramatically among the countries, with Japan showing the lowest diversities and south Asia showing the highest. Additionally, highly virulent blast races were found to be distributed at high frequencies in West Africa and northeast China. Additionally, the differential system consisting of DVs and standard differential blast isolates was also developed in each institute, becoming one of many achievements from pathological studies. The differential system is a basic tool for the characterization of resistance genes in rice cultivars and the pathogenicity of blast isolates. Using the differential system developed in each institute, genetic improvement of leading rice cultivars is being conducted through introduction of partial resistance genes, such as pi21, PB1, Pi34, Pi35, and Pi38. Multiline varieties with genetic backgrounds of Indica Group rice cultivars, IR 64 and IR 49830-7-1-2-2, are also being developed. These differential systems, leading rice cultivars introduced with partial resistance genes, and multiline varieties, will be the key materials toward development of a durable protection system, which will be implemented in harmony with environmental conditions and contributing to sustainability in rice cultivation.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"JIRCAS International Symposium 2019, Session 2: Important Migratory Diseases and Quarantine\nChair: Yoshimichi Fukuta","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","dateValue":"2025-02-07"}],"displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"2020-01"}],"filename":"International_symp2019-_47-52.pdf","filesize":[{"value":"970.1 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"International_symp2019-_47-52","objectType":"fulltext","url":"https://jircas.repo.nii.ac.jp/record/2000705/files/International_symp2019-_47-52.pdf"},"version_id":"062dd4b5-1e22-4697-b92b-6e88ef61f52d"}]},"item_30002_identifier_registration17":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34556/0002000705","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 (JIRCAS)","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":"International research collaboration to tackle transboundary plant pests : Contributions to Sustainable Development Goals"}],"subitem_relation_type":"isPartOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.34556/0002000694","subitem_relation_type_select":"DOI"}}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference presentation","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_30002_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"International collaborative research networks for rice blast","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":"International collaborative research networks for rice blast","item_type_id":"40039","owner":"74","path":["1735004988747","1738644224004"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-02-07"},"publish_date":"2025-02-07","publish_status":"0","recid":"2000705","relation_version_is_last":true,"title":["International collaborative research networks for rice blast"],"weko_creator_id":"74","weko_shared_id":-1},"updated":"2025-02-18T04:22:19.926810+00:00"}
