The large-grain rice cultivar Akita 63 showed higher N-use efficiency for grain production. To elucidate this, we analyzed yield characteristics of Akita 63 in comparison with those of a maternal cultivar, Oochikara with a large grain, a paternal cultivar, Akita 39 with a normal grain, and a Japanese leading cultivar, Akitakomachi. The yields of Akita 63 were 20% higher than those of Oochikara and Akita 39, and 50% higher than those of Akitakomachi for the same N application. Akita 63 showed superior N uptake capacity. Whereas a trade-off between single grain weight and grain number was found for Oochikara, Akita 63 did not show such a relationship. The success in Akita 63 breeding was due to overcoming such a trade-off. Akita 63 had the large-grain alleles of GS3 and qSW5. Thus, an enlargement of grain size can have a great impact on an increase in yield with improved N-use efficiency. However, an enlargement of sink capacity led to source limitation. Thus, both sink and source improvements are essential for a further increase in the yield of today’s high-yielding cultivars.","subitem_description_type":"Abstract"}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Nature"}]},"item_16_relation_17":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"High yielding ability of a large‑grain rice cultivar, Akita 63"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.nature.com/articles/s41598-020-69289-0","subitem_relation_type_select":"URI"}}]},"item_16_relation_26":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1038/s41598-020-69289-0","subitem_relation_type_select":"DOI"}}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© The Author(s) 2020"}]},"item_16_rights_19":{"attribute_name":"権利URI","attribute_value_mlt":[{"subitem_rights":"http://creativecommons.org/licenses/by/4.0/"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"20452322","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Agricultural Science, Tohoku University"},{"subitem_text_value":"Faculty of Bioresource Sciences, Akita Prefectural University"},{"subitem_text_value":"Japan International Research Center for Agricultural Sciences"},{"subitem_text_value":"Graduate School of Agricultural Science, Tohoku University"},{"subitem_text_value":"Graduate School of Agricultural Science, Tohoku University"},{"subitem_text_value":"Graduate School of Agricultural Science, Tohoku University"},{"subitem_text_value":"Graduate School of Agricultural Science, Tohoku University, Faculty of Agriculture, Iwate University"},{"subitem_text_value":"Graduate School of Agricultural Science, Tohoku University"}]},"item_16_version_type_27":{"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":"MAKINO, Amane"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YOSHIHIRO, Kaneta"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OBARA, Mitsuhiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ISHIYAMA, Keiki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KANNO, Keiichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KONDO, Eri"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SUZUKI, Yuji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MAE, Tadahiko"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-12-09"}],"displaytype":"detail","filename":"sr-v10p12231.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"sr-v10p12231","url":"https://iwate-u.repo.nii.ac.jp/record/15469/files/sr-v10p12231.pdf"},"version_id":"d89261c5-7cad-4102-ba74-8b256eb92213"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"High yielding ability of a large‑grain rice cultivar, Akita 63","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High yielding ability of a large‑grain rice cultivar, Akita 63"}]},"item_type_id":"16","owner":"19","path":["1510"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-12-09"},"publish_date":"2021-12-09","publish_status":"0","recid":"15469","relation_version_is_last":true,"title":["High yielding ability of a large‑grain rice cultivar, Akita 63"],"weko_creator_id":"19","weko_shared_id":-1},"updated":"2023-05-15T13:04:10.594403+00:00"}
