dc.description.abstract | 本研究以秈型稻耐旱品種‘HY15’為貢獻親,而臺灣優良稉型稻‘TK9’為輪迴親,透過回交方式將‘HY15’之耐旱性轉移至‘TK9’。過程中利用28%聚乙二醇6000 polyethylene glycol 6000; PEG-6000)溶液的模擬缺水逆境處理,挑選出耐旱的植株,並於各回交世代之BCxF1 與BC4F2 進行分子標幟輔助背景選拔。結果發現,BC2F1、BC3F1、BC4F1 及BC4F2 世代回復輪迴親遺傳背景之比率分別為86.2、91.6、94.5及93.0%。而以‘HY15’、‘TK9’及10 個BC4F4品系於三葉齡、五葉齡及七葉齡等3 個幼苗時期,分別以28% PEG-6000 模擬缺水之水分逆境處理評估材料之耐旱性表現,試驗發現多數品系之耐旱性表現優於輪迴親‘TK9’,顯示已將’HY15’之耐旱特性導入‘TK9’中,培育出高耐旱之稉型稻新品系。進一步評估12 個耐旱品系 (BC4F4)在水分管理下產量與構成要素表現,結果發現DT22 擁有較重的穗重,DT38 和DT56則具較高稔實率,三個品系稻穀產量皆達5,000kg ha-1 以上,顯示獲選之三個耐旱品系具有缺水環境下之實際耐旱性栽培價值,未來可命名成為適合臺灣栽培利用之耐旱水稻新品種潛力。 To introgress the gene(s) conferring drought-tolerance to the Taiwanese elite japonica cultivar ‘Taikeng 9 (TK9)’, a drought-tolerant cultivar ‘Hang-yu 15 (HY15)’ was used as a donor parent crossed to ‘TK9’. Four backcrossing practices were conducted and the progenies of each backcross generation BCxF1 were screened for drought tolerance by treating with 28% PEG-6000 solution and consequently selected by molecular markers to recover the recurrent parent’s genome. | en_US |
