These information include electrical resources, papers, experimental data, mathematical models, simulations, URLs, etc. Hence, it is necessary to develop a database system to integrate these disparate resources into a single base named XooNIps, which serves as the Base Platform for each research fields. 20090915--> Home News Forum 20090915--> Advanced Search--> Login XooNIps検索    全て タイトル & キーワード メタデータ Article      詳細検索 インデックスツリー open all close all Public 全て タイトル & キーワード メタデータ Article --> 詳細 閲覧数:1585 ID AN00181569-19751200-1008 アイテムタイプ Article このアイテムを表示する 画像 本文 AN00181569-19751200-1008.pdf Type : application/pdf Size : 103.9 KB Last updated : Nov 19, 2010 Downloads : 811 Total downloads since Nov 19, 2010 : 811 タイトル The Extremely Frequent Occurrence of Haploids in Some Plants of a Common Wheat Strain with the Aegilops tyiuncialis Cytoplasm 著者 T.Ryu ENDO (Endo ryu) 教養部 T.KATAYAMA (katayama) 教養部 版 Publisher 出版地 奈良 出版者 奈良大学 上位タイトル 奈良大学紀要 (Memoirs of the Nara University). Vol.4号, (1975. 12) ,p.90- 94 識別番号 ISSN 03892204 抄録 Many attempts have been made to obtain haploid plants of various species, with some positive results. Except for anther culture, however, all methods so far have been successfully applied to only a very limited number of species: i,e., pollination of Xrayed pollen grains in Triticum monococcum (Katayama, 1934); selection of specific strains with effective screening in Zea mays (Chase, 1949); use of an alien cytoplasm in T. aestivum (Kihara and Tsunewaki, 1962); and elnbryo culture in Hordeum vulgare(Kasha and Kao, 1970)and T. aestivum (Barclay, 1975). At present, alien cytoplasms are quite useful for inducing haploids in a single strain of common wheat, T. aestivum strain Salmon, and their effect on haploid induction in this strain is rather prominent and stable. Eight species of the genus Aegilops, a related genus of Triticum, are known to possess cytoplasms that induce haploids when incorporated with Salmon&＃039;s nucleus(Tsunewaki et al., unpubl.). Ae. triuncialis is one of them. This year we found four plants of Salmon with the Ae.triucialis cytoplasm that produced so many haploid and twin seedlings that maintenance of the line became almost impossible. We here report the extraordinarily high frequency of haploids and twins observed in the four plants of this line, and discuss briefly the cause. 言語 eng 資源タイプ text ジャンル Departmental Bulletin Paper Index / Public / 奈良大学紀要 / 4号 関連アイテム
