摘　　要：倒伏是限制小麦产量增长和品质提升的主要因素之一,解决好倒伏与产量、品质之间的矛盾关系至关重要。本文对小麦茎秆强度的遗传特性、影响因素、鉴定方法及应用进行综述,分析得出茎秆强度是决定小麦抗倒伏能力的最重要因素。从生产实践和育种经验的角度应高度重视茎秆强度与茎秆弹性(回弹力)的同步选择,茎秆强且弹性好的小麦品种抗倒伏能力强,是小麦抗倒伏育种的理想选择。Lodging is one of the main limiting factors for yield increased and quality improvement of wheat.It is very important to solve the contradiction between lodging and yield and quality.In this paper,the genetic characteristics,influencing factors,identification methods and application of wheat stem strength were discussed.It can be concluded that stem strength is the most important determinants on wheat lodging resistance.From the angle of production practice and breeding experience,we should attach great importance to the synchronous selection of stem strength and stem elasticity(reaction force).Wheat varieties with strong stem and good elasticity have strong lodging resistance,so they are the ideal choices of lodging resistance breeding.
