摘　　要：超级杂交稻具有净光合速率高、光合功能期长、群体光合优势明显、物质积累量大、后期灌浆时间长、抽穗前物质积累具有重要作用、光合产物积累与籽粒灌浆对物质的需求相协调等特点。结合第1,2,3期超级杂交稻的株型特点,就未来的杂交稻超高产育种从光合作用、干物质积累角度提出了建议。Compared with common high-yielding hybrid rice, super hybrid rice shows the characteristics of higher net photosynthetic rate, longer functional duration of photosynthesis, higher population photosynthesis, greater dry matter accumulation, longer grain-filling period, higher accumulation of dry matter before heading and better coor- dination between photosynthate accumulation and grain-filling need. Based on plant type characteristics of Phase Ⅰ, and Ⅲ super hybrid rice, the proposal was put forward for future super hybrid rice breeding in the aspects of photosynthesis and dry matter accumulation.
