摘　　要：文章从玉米耐密性的遗传改良、影响因素以及高密度的不利影响等方面,对国外玉米耐密性的研究进展进行了综述,指出现代玉米杂交种的产量提高主要归功于耐密性的增强;耐密性是一个复杂的生理性状,受很多因素的影响;高产性和稳产性的统一是现代优良杂交种的必备条件。Foreign research progress on tolerance to high plant density in maize was reviewed in this article,including the aspects of genetic improvement and influence factors of tolerance to high plant density,as well as adverse effects of high density. The increased yield of modern maize hybrids was mainly owed to enhance of plant density; tolerance of high plant density is a complex physiological trait,which was influenced by many factors; the unity of productivity and stability is prerequisite for outstanding modern hybrids.
