標題: | 玉米雜種優勢之基因表現差異分析(第一年) | 作者: | 林順福 | 關鍵字: | 玉米;雜種優勢;基因 表現差異分析;細胞質效應;Maize;Heterosis;Differential display;Cytoplasmic effect | 公開日期: | 31-七月-2000 | 出版社: | 臺北市:國立臺灣大學農藝學系暨研究所 | 摘要: | 本計劃利用新近發展之基因表現差異 分析技術,探討玉米雜種優勢之遺傳機 制。試驗使用之材料為單雜交品種台農一 號、台農二號及其自交系親本。試驗結果 顯示在台灣北部地區台農二號較台農一號 能表現雜種優勢;正反交配對產量性狀有 較大影響,對株高及穗長之影響較小;同株 自交所產生自交系其生長活力稍低於姊妹 株交配者;基因表現差異產物分析結果顯 示有顯性作用存在,而且細胞質之遺傳物 質亦可能與雜種優勢之表現有關,有待進 一步探討。 This project was to study the genetic mechanisms of heterosis in maize with a newly developed technology, differential display. Two singlecross cultivars, including TNG 1 and TNG 2, and their inbred parents were used in this experiment. The result indicated single-cross cultivar TNG 1 expressed better hybrid vigor in the northern area of Taiwan than TNG 2. The effects of reciprocal crosses were obvious in yield but not in plant height and ear length of corn. Inbred plants propagated from sib-mating had less weakness than plants from selfpollination. Dominance effect was observed in the differential display (D.D.) analysis. Cytoplasmic effect was also detected based on the band density of D.D. More studies are needed to reveal the relation between agronomic traits and D.D. results. |
