The photosynthetic rate at the flowering stage was lower than that at the panicle initiation stage in all the inbred parent cultivars and F_1 hybrids. Heterosis in photosynthetic rate was higher at the panicle initiation stage than that at the flowering stage. Pre-anthesis leaf area in the F_1 hybrid was significantly larger than that in the parent cultivars. However, the post-anthesis decline in leaf area was more rapid in the F_1 hybrids than in the parent cultivars and its magnitude was the highest in the F_1 hybrid of Z × A which was tall having long and curved panicles. Pre-anthesis dry matter accumulation in both hybrids was significantly higher in the F_1 plants than the parental cultivars, but post-anthesis dry matter accumulation in the F_1 hybrid was lower than the mid-parental value in Z × A. The degree of heterosis in grain yield varied with the hybrid combination, an average heterosis being 1.03. Heterosis in grain yield was closely associated with heterosis in harvest index.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"en","subitem_1522300316516":"The Crop Science Society of Japan"},{"subitem_1522300295150":"ja","subitem_1522300316516":"日本作物学会"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4867"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"1343-943X"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AA11162156"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"en","subitem_1522650091861":"Plant Production Science"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1998-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicPageEnd":"239","bibliographicPageStart":"233","bibliographicVolumeNumber":"1"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"Vol1No4p233-239.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2003588/files/Vol1No4p233-239.pdf"},"version_id":"98571880-2d86-4f73-9a1a-c016d5ce32c4"}]},"item_title":"Physio-morphological Studies of F_1 Hybrids in Rice (Oryza sativa L.) : Photosynthetic ability and yield","item_type_id":"15","owner":"1","path":["1642838338003","1642838407312"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-03-07"},"publish_date":"2008-03-07","publish_status":"0","recid":"2003588","relation_version_is_last":true,"title":["Physio-morphological Studies of F_1 Hybrids in Rice (Oryza sativa L.) : Photosynthetic ability and yield"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-08-03T05:39:44.721571+00:00"}
