本研究以两系法杂交组合两优培九、６５３９６ 和汕优６３（ ＣＫ） 为试验材料，采用分期播种和平行比较观测方法，对供试材料的绿叶数量、功能叶面积、比叶重等光合性状进行了比较分析，同时根据三个品种的功能叶叶角测定结果，从理论上计算了不同株型的受光状况。这些研究成果可以为超级稻育种目标提供必要的技术依据。
In this study, the two-line hybrid combinations, Liangyoupeijiu 65396 and Shanyou 63 (CK), were used as experimental materials to evaluate photosynthetic characteristics such as leaf number, functional leaf area and specific leaf weight The comparative analysis was carried out. At the same time, the light-receiving conditions of different plant types were calculated theoretically according to the determination results of functional leaf-angle of the three cultivars. These research results can provide the necessary technical basis for the super rice breeding goal.
