• 中文摘要： 以具有臺中65號之遺傳背景的 14 個早熟同質遺傳因子系統為材料，播種於四個不同環境條件（30°C, 20°C，施氮肥及無肥），生育 20 日後，調查秧苗特性，探討早熟遺傳因子對秧苗性狀之多效性作用，結果大約如下： (1)早熟遺傳因子對秧苗特性具有多效性作用，其程度因各個早熟遺傳因子之不同而有差異。一般第二、三葉及苗長具有增大之傾向。 (2)所調查的秧苗性狀，環境與早熟系統間具有交感作用。 (3)秧苗之生育特性與抽穗期間之相關，一般部很低而不顯著。
• 英文摘要： The pattern of pleiotropic effects of 14early-maturing genes on seedling characters wasinvestigated by using isogenic lines having thesame genetic background of a Taiwanese variety,"Taichung 65". Generally, early-maturing genes seemed toconnected with the elongation of the upperleaves of the seedlings (the second leaf sheath,the third leaf sheath and leaf blade), but thepleiotropic effect appeared to vary with indiv-idual genes. Environment and early-maturinggene interaction was significant for every seedl-ing character investigated in this study. Thecorrelation between each seedling character andheading date of the adult plant was very small.
