Abstract
使用中粒型水稻品種臺農 67 號、大粒型品種 Pegonil 及以前者為輪迴親回交五代(並自交五代)或回交六代(並自交四代)的粒重型系統各兩個，在第二期作於田間進行試驗，調查產量與乾物質生產能力，分析各器官全氮濃度，並解析氮素利用效率的表現，以瞭解粒重變異與氮素含量及分配對產量生理的影響。四個回交系統的全乾物質與稻穀產量均高於大粒親本 Pegonil ，並與臺農 67 號相同但未能超越，單位面積穎花數仍為產量之限制因子。
A medium-grain variety, Tainung 67, a large-grain variety, Pegonil, and two each of their BC-5 and BC-6 offsprings with grain weight between 30.5-32.7 mg were used to study the relationship between grain weight and characteristics of N utilization. Yields of total dry matter and grain of the backcross offsprings were comparable to those of the high-yielding Tainung 67 and exceeded those of Pegonil.
