摘　　要：理想株型与杂种优势利用相结合是实现水稻单产突破的重要途径之一。综述了理想株型的概念、株型构成因子及其相互关系、国内外株型育种的主要理论及存在的问题。提出了动态理想型的株型观点和水稻动态理想型的主要塑造途径,对水稻动态理想型育种进行了展望。It has been proved that morphological improvement combined with utilization of heterosis is one of the most important ways to raise rice yield ceiling genetically. The authors reviewed the major findings of ideal plant type breeding, including the concept of ideal plant type, the components of plant type and their interrelation. Based on the analysis of advantages and constraints in existing plant type models and modem breeding programs, a viewpoint of dynamic ideotype was put forward and discussed for shaping its specific morphological structure in the growth cycle of rice.
