Abstract: Lodging is one of the important factors affecting the yield and quality of oat. It is a prominent problem to be solved urgently in the breeding and production of oat. Strengthening the systematic research on the physiological and molecular mechanisms of oat lodging resistance is of great significance for promoting the germplasm innovation of oat lodging resistance and cultivation with high yield and high efficiency. Based on that objective,the study on lodging of oats is summarized systematically up in this paper,the influencing factors of lodging occurrence and the status quo of lodging resistance evaluation of oat were combed,the research progress in the morphology,physiology and anatomy of lodging resistance of oat was reviewed,the relationship of plant morphology,physical and chemical substances and cultivation measures with the lodging of oat was summarized up as well. In this paper,we prospected the researches on the characteristics of stem mechanics,endogenous material synthesis,genome wide association study (GWAS) of lodging resistance traits and quantitative trait locus (QTL) mapping.,functional gene mining and molecular mechanism analysis of oat,in order to provide references for the genetic improvement and breeding of the inverted resistance varieties of oat,and promote the development of researches on stress resistance of oat.

摘要: 倒伏是影响燕麦产量和品质的重要因素之一,也是目前燕麦育种和生产中亟需解决的突出问题。加强燕麦抗倒伏生理和分子机制的系统研究,对促进燕麦抗倒伏种质创新和丰产高效栽培具有重要意义。基于此,本文对燕麦倒伏方面的研究进行了系统总结,梳理了燕麦倒伏发生的影响因素和抗倒伏性鉴定评价现状,综述了燕麦抗倒伏形态学、生理学及解剖学等方面的研究进展,归纳了植株形态、理化物质、栽培措施等与燕麦倒伏的关系。并针对燕麦茎秆力学性能与内源物质合成,抗倒伏相关性状全基因组关联分析(Genome wide association study,GWAS)分析及数量性状位点(Quantitative trait locus,QTL)定位,功能基因挖掘与分子机制解析等研究进行了展望,旨在为我国燕麦遗传改良和抗倒品种选育提供参考,进而推动燕麦抗逆性研究的发展。
