In this paper, factors which influenced maize stem lodging were analyzed, research methods of lodging and evaluation index of maize varieties with different lodging resistance summarized. Ideal plant type of stem lodging resistant varieties was put forward based on previous research. This will provide reference for higher lodging resistant maize breeding and cultivation.
