摘　　要： 在回顾国内外水稻超高产育种的理论与实践的基础上 ,指出必须通过目标创新、技术创新 ,实现超级稻新的突破。一是创制新种质、新材料 ,二是注重理想株型构建中几个关键性状的选择 ,三是开展生理生态理想型育种 ,四是分子标记辅助选择数量性状基因座 (QTL ) ,五是实施理想株型栽培 ,从而实现水稻超高产与优质、多抗及广适应性的同步改良与全面突破。 Based on the theory and practice of the rice breeding for super high yield at ho me and broad, this article indicated that objective and technological innovation can realize new transcendency in super rice. Some strategies are as follows: Fi rstly, We must create new germplasm and materials. Secondly, We should pay atten tion to the choice of several key characteristics during the construction for id eo-type. The third is to develop breeding for ideal physiological and ecologica l type and to choose QTL by marker-assisted selection. The next is to implement ing the culture of ideo-type. The final is to realize the simultaneous improvin g and comprehensive transcending ultrahigh yield, quality, resistance and adapta bility in rice.
