Advances on Studies Relating to Lodging Resistance of Rice Plant

Relevant literatures on the studies relating to the lodging resistance of rice (Oryza sativa L.) plant published in China and abroad in the past two decades were reviewed. This article summarizes the genetic factors and regulation mechanisms of the resistance, as well as the applicable methods for identifying and evaluating the property that closely affects rice production. Taking the interrelations between lodging resistance and other factors, such as panicle type, physical strength of stem at the base, root morphology, and plant type, into consideration, the conclusion can become rather complex. It was suggested, in preventing or mitigating permanent displacement of rice plant parts due to external effects, breeding new varieties to restrict plant height be applied conservatively. By using conventional cross breeding along with the newly available molecular biotechnology, varieties could be generated to simultaneously be lodging-resistant as well as highly desirable on other quality concerns. Meanwhile, perfecting the cultivation, standardizing the identification and evaluation protocols, and utilizing the techniques of modeling and UAV remote sensing to establish a digital lodging warning system in the field would help to accelerate the advancement on the management and improvement of lodging resistance of rice plants for an optimal production performance.
