Abstract:

Lodging is a key factor which restricts the wheat production. The lodging resistance improvement of wheat is beneficial to the harvest mechanization and agricultural production efficiency of wheat. Furthermore, the grain yield and quality can also be improved. In order to clarify the cause and the mechanism of lodging and its effects on wheat yield and quality, this paper summarized four aspects including the influencing factors, the lodging mechanism of stem, the effect of lodging on yield and on grain quality. Finally, key measures of lodging resistance and the future research direction were pointed out from two perspectives of breeding and cultivation measures. In the aspect of breeding, we should combine agronomic traits (such as plant height, stem thickness and filling rate) with mechanical properties (such as stem breaking resistance), and select high-yield and lodging-resistance varieties. In cultivation, we should pay attention to the coordination of different measures to achieve high yield and lodging resistance at the same time.

Key words: wheat, lodging resistance, mechanism of lodging, variety breeding, cultivation measures
