倒伏严重影响玉米产量而且还影响玉米的机械化收获，是当前玉米生产和育种中一个主要问题。玉米的抗倒性受到植株受力因素与植株支持系统两方面的影响。讨论提高玉米抗倒性的遗传因素以及综述与其相关的遗传机制研究进展。

Lodging has seriously influenced the yield and mechanical harvesting of maize, and it is a major problem on maize production and breeding. Lodging resistance is controlled by traits affecting load and plant supporting system. How to improve the genetic factors of maize lodging resistance and associated research progress of the genetic mechanisms were discussed in this paper.
