摘　　要：株型是水稻重要农艺性状,与产量、品质及抗逆性有密切关系。株型改良过去曾对水稻育种发挥了重要作用,未来还将对水稻育种产生深远影响。本文结合沈阳农业大学水稻团队相关工作,从株型的概念、株型育种研究简要回顾、株型生理生态与遗传基础等方面综合评述了水稻株型研究进展,还讨论了水稻株型相关领域存在问题与发展方向。充分利用现代分子生物学相关理论与技术最新研究结果,解析群体与个体、个体器官之间的相互关系及其优化组合模式,明确生理生态基础及其分子调控网络并付诸株型育种实践,有望实现更高水平上全方位的水稻“理想株型”。Rice is one of the most important crops in China and even the world.Plant type is an important agronomic trait of rice,which is closely related to yield,quality,and stress resistance.Plant type improvement has played an important role in rice breeding in the past,and will have a profound impact on rice breeding in the future.On the base of related achievements of Rice Research Institute of Shenyang Agricultural University,this paper comprehensively reviewed the research progress of rice plant type from the aspects of the concept of plant type,physiological ecology,and genetic basis of plant type breeding,and also discussed the existing problems and development direction of rice plant type.With the application of the latest research results of modern molecular biology,analyze the relationship between various organs and their optimal combination among population and individual,define the physiological ecology basis and the molecular regulatory network,and apply to plant type breeding practice,which is expected to achieve a higher level of“ideal plant type breeding”of rice.
