中文摘要 | 本試驗以兩個稉稻品種(越光與台農67號)雜交所產生之102個F2衍生系為材料,調查11個重要農藝性狀,共定位得到42個數量性狀基因座(QTL),其中2個(qHD-3、qHD-10)與抽穗期相關;4個(qPH-2、qPH-7、qPH-9、qPH-10)與株高相關;3個(qNT-8、qNT-9、qNT-10)與分蘗數相關;7個(qFLL-2、qFLL-3、qFLL-4、qFLL-5、qFLL-9、qFLL-10、qFLL-11)與劍葉長度相關;5個(qFLW-3、qFLW-4、 qFLW-6、qFLW-11、qFLW-12)與劍葉寬度相關;5個(qGY-1、qGY-7、qGY-8、qGY-9、qGY-10)與產量相關;1個(qPN-3)與穗數相關;5個(qSN-3、qSN-8、qSN-9、qSN-10、qSN-12)與每穗粒數相關;3個(qSF-7、qSF-8、qSF-11)與稔實率相關;2個(qTGW-1、qTGW-7)與千粒重相關;5個(qPW-1、qPW-3、qPW-8、qPW-9、qPW-12)與平均穗重相關。其中以qHD-10的概度值最大(LOD=8.1),對抽穗期的變異解釋量亦最大(29%),而比對GRAMENE資料庫與相關研究,可知該QTL為已選殖確認之Ehd1基因。另由本試驗結果,位於水稻第10條染色體在63cM附近可同時得到與抽穗期、株高、分蘗數、劍葉長、產量及每穗粒數等性狀相關之基因座,該位點緊密連鎖之分子標誌(RM5304)可直接作為稉稻育種選拔之利用。 |
英文摘要 | The major agronomic traits of 102 F2-derived lines obtained from a cross between Koshihikari and Tainung No. 67 were surveyed for QTL mapping. Among 42 mapped QTL, two QTL (qHD-3 and qHD-10) associated with heading date, four QTL (qPH-2, qPH-7, qPH-9 and qPH-10) associated with plant height, three QTL (qNT-8, qNT-9 and qNT-10) related to tiller numbers per plant, seven QTL (qFLL-2, qFLL-3, qFLL-4, qFLL-5, qFLL-9, qFLL-10, and qFLL-11) related to flag leaf length, five QTL (qFLW-3, qFLW-4, qFLW-6, qFLW-11, and qFLW-12) associated with flag leaf width, five QTL (qGY-1, qGY-7, qGY-8, qGY-9 and qGY-10) related to grain yield, one QTL (qPN-3) influencing panicle numbers, five QTL (qSN-3, qSN-8, qSN-9, qSN-10 and qSN-12) relevant with spikelet numbers per panicle, and three QTL (qSF-7, qSF-8 and qSF-11) associated with performance of spikelet fertility, two QTL (qTGW-1 and qTGW-7) corresponded to 1000-grain weight, and five QTL (qPW-1, qPW-3, qPW-8, qPW-9 and qPW-12) related with average panicle weight were identified, respectively. Among all of them, qHD-10 was detected with the highest LOD value (8.1) and contribution of phenotypic variance on heading date (29%). This gene was verified as cloned Eh1d based on GRAMENE database and related researches. Besides, several QTL related with heading date, plant height, tiller numbers, flag leaf length, grain yield and grain numbers per panicle were congruently detected around 63 cM region of chromosome 10. A closely linked marker (RM5304) at this region could be used for indirect selection in the rice breeding program. |
