order to investigate the presence of a fertility-restoring gene or genes for a completely male-sterile strain with Oryza sativa cv. Lead Rice cytoplasm (cms-2) and a completely male-sterile strain carrying the cytoplasm of O. perennis, 213 commercial lowland-rice varieties of Japan were crossed to the former strain and 214 varieties to the latter. From the F_1 progeny of each cross, five plants were planted to examine their pollen and seed fertilities and also to determine whether to be varieties having fertility-restoring gene(s) or not. For cms-2 strain, 27 of the 213 varieties possessed fertility-restoring gene(s) and the remaining 186 carried non-restorers. Out of the 27 varieties carrying fertility restorers, 22 were distributed in the southern region of Japan (Kyushu, Chugoku, Shikoku and Kinki districts) and the remaining five were present in the northern region (Chubu, Kanto, Tohoku, and hokkaido districts). On the other hand, out of 186 non-restorers, 111 were distributed in the northern and 75,in the southern region. The frequency of the gene(s) was higher in the northern than in the southern region. Of the 27 varieties having restorers, 19 (ca. 70%) were bred by pure-line selection from their naive ones and the remaining eight (ca. 30%) were by the hybridization breeding methods. For cms-3 strain, all of the 214 varieties possessed non-restoring genes. It suggests that male-sterile lines of japonica with the cytoplasm of cms-3 can be bred easily. If an effective restorer for cms-3 cytoplasm is discovered, the cytoplasm and its fertility-restoring gene(s) will be utilized extensively in the basic studies on hybrid rice breeding in Japan. In the present investigation, the fertility-restoring gene9s) for cms-2 cytoplasm did not restored fertility in the cms-3 cytoplasm. It indicated that the above two cytoplasms were of different nature in each other.","subitem_description_type":"Other"},{"subitem_description":"\u7d00\u8981\u8ad6\u6587","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4224"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
